What are MVC, MVP and MVVM Design Patterns?

There are three types of design patterns commonly used in today’s technological generation. The MVC, MVP and MVVM. Here is a brief description about the three.

MVC Pattern

Model View Controller is defined as an architectural software pattern used for executing user interface on computers which was introduced in 1970s. It separates given software into three parts which means that controlled logic and domain model are decoupled from user interface which allows the testing and maintenance go easier.
MVC pattern splits an application basically into three parts. They are;
• Model: A model depicts the set of classes which further describes the business logic i.e. data model. It delineates the rules for business data which can be manipulated and changed further.
• View: The View depicts the User Interface modules like jQuery, CSS, html, etc. View only displays the data that is obtained from the controller as outcome.
• Controller: The Controller processes the incoming requests. Controller receives the input from the user via the View; further it processes the data with the help of Model and then sends it back to View as a result. Characteristically, it acts as a manager between Model and View.
Presently, this pattern is in common use by popular frameworks like,
• Spring Framework
• Ruby on Rails
• Apple iOS development.

MVP Pattern

MVP stands for Model View Pattern, which is derived from the Model View Controller architectural pattern. In this, the controller is replaced by presenter. In this, the application is broken into three aspects;
• Model: Like in previous case, the model depicts a set of classes that illustrates the business logic and data.
• View: The View is described as passive interface which displays data, and directs the event to presenter which further acts upon it.
• Presenter: The presenter retrieves the data from model and further formats it for display to the View. Presenter does not coordinate the incoming request like controller.
MVP Pattern is widely used with,
• Window forms
• ASP.NET

MVVM Pattern

Model View-View Model is an architectural software pattern. MVVM supports two-way data binding between View and view model. It is a value converter which enables the automatic proliferation of changes, within the View to the state of View model.
As briefed before, the Model and View in MVVM represents the business logic and UI components. While View model is accountable for commands, exposing methods and other properties that helps to preserve the state of view and to influence the model as the outcome of action in the view.
The MMVM Pattern is mostly used by;
• nRoute
• Silverlight
• WPF and
• Caliburn.
In conclusion, all of the three have some similarities and some differences. All the three have MV i.e. Model and View common with some advantage over one another.

Migration from SharePoint on Premise to SharePoint Online on Office 365

If you are planning to migrate from SharePoint on

Premise to SharePoint online, you should assess that which SharePoint capabilities are best for implementation in your Office 365 environment.

Analysis of accessible SharePoint Environment

It is important for you to deeply analyze the current environment of your SharePoint before you decide to migrate. The analysis should highly be focused on the SharePoint contents and workloads that you are planning to move to SharePoint Online.  After the analysis is performed, you will get a crystal clear understanding of the content and customization you have on your On-Premise setting.

After the analysis is done, you should now create content and customization road map that will cover exactly what content and customization will move to SharePoint Online and how they will be moved. For every customization you will need to decide if you want to provide that precise functionality in your SharePoint Environment. In the next step, you will be needed to authenticate if the customization can be applied as sandboxed solution or not.

Content Migration

The most common method of manually moving your content to SharePoint Online is by attaching the SharePoint Library to the SharePoint Workspace. Now, one can further upload the contents to SharePoint Workspace and later it would automatically get the files synchronized to SharePoint Online. Another popular method is to use the ability of SharePoint to upload numerous files which will allow you to upload batches of documents instantly.

Below is the method illustrated on how Office 365 gives method for migrating numerous files to SharePoint Online.

• Microsoft FastTrack: Microsoft FastTrack is a method used for tools and guidance while migrating one’s data to cloud.
• SPO Migration Content Roadmap: To form migration import job Office 365, one can use SPO migration API and queue it up for afterward processing by a separate timer job.
• Windows PoweShell cmdlets for SPO Migration Public Preview: If you want to transfer content from an on-premises SharePoint or an on-premise file share site office 365, you can use Windows PowerShell cmdlets for SPO Migration Public Preview.

It is important to validate whether the tool meets your migration requirements before choosing the migration tool to transfer your SharePoint content. Also, it is important to check whether it supports all the SharePoint relics you want to migrate. Refer towards the third party tool’s documentation and calculate what preparation steps your organization will require to implement.

Client Focus

Client is the main part of any business organization and client satisfaction is the most important issue for its success. An organization’s orientation moves toward serving its clients’ needs. Having Client focus is usually a strong contributor to the overall success of a business and involves ensuring that all aspects of the company put its customers’ satisfaction first. In general, the model of client satisfaction can be split into two sections – Differentiators and Essentials.

• Differentiators set you apart from the crowd as you actively demonstrate trust, openness and respect, pro-activity, anticipation of problems and problem solving, communication, planning and work shopping, team working etc.
• Essentials are required for quality, cost and time predictability, resources, health and safety, appropriate experience and expertise, financial stability etc. An organization will excel to both of its internal or external clients by focusing efforts on discovering and meeting their needs.

To make apt responses to clients’ requests an organization needs to meet client needs by effectively responding to requests, working efficiently to satisfy client and organizational expectations.

At AnAr Solutions, we maintain professionalism, remain helpful and responsive to all our clients’ needs, seek clear understanding of client requirements and outcomes, gain acceptance for ideas and solutions before proceeding to the next step. An organization must communicates in a language that the client understands and consults the client in clarifying priorities.

To build up positive client relations organizations must maintain ongoing communications and interaction with clients to anticipate and prevent potential problems, keep clients up-to-date with information and decisions that affect them, balances client requests with other priorities (e.g. safety regulations). They should clearly represents risks and liabilities to client and seeks feedback about client satisfaction and outlines and explains the benefits of proposed solutions.

To evaluates and adapt to the clients’ focus an organization must adhere to the following:

• Identify benefits for the clients and looks for ways to add value and looks for opportunities to save money or resources for client.
• Adapt methods, schedules, equipment, products or solutions to meet client needs and responds to changes in project scope by re-negotiating deliverables, work plans, etc.
• Know how to distinguish client desire and client need in order to define realistic expectations and involve clients in assessing service, solutions or products to determine ways to improve service.

To measure customer satisfaction a we at AnAr Solutions, have framed specific client oriented policies. They can obtain complains through their customer service center and encourage further suggestions from the customers to satisfy their future needs.

What Does Application Security Cost? – Your Job!

As most assets of an organization are available on servers, the external threat is imminent, and one must be prepared for it. An appropriate lineup of application security will ensure that an organization’s applications stay protected with software, hardware, and procedural methods to protect applications from external threats.

Often a neglected concept in software design, security is now an issue of concern for several organizations as networks are now incredibly easy to hack into and access thereby exposing the applications to serious threats. However, with security measures that scan all your applications and possesses a thorough security routine that monitors and restricts attempts from unauthorized officials that use code to alter access to the organization’s most secure applications featuring sensitive data.

An impenetrable application security, a leading contributor in the assessment of an organization’s brand perception, is capable of storing a large amount of sensitive data on the cloud storage using private servers and other software.

Aftermath of an improper application security: Recently, Beth Jacob, CIO of Target Stores for over seven years resigned. The reason behind his unusual resignation was a leak of private data of over 70 million of Target’s customers. As a result, the losses suffered by Target were massive excluding the legal remunerations. Target’s CEO Gregg Steinhafel later announced their plans to hire a more experienced CIO and make amends for their losses by completely overhauling their information security network. This is just another example of many scenarios wherein the lack of application security has cost organizations their dignity and negligent associates their jobs. The cost incurred by an organization is staggering and the sole person responsible for the mess is the CEO. Even a single hit by the IT security department would put the CEO in a difficult position.

What it could cost: The CEO’s and CIO’s are now required to qualify their abilities to organizations, not just in their managerial skills, but also in their ability to minimize risks, monitor application security protocols, and be perseverant. Another major effect of application security is in the cost to the company. Earlier, using advanced security measures and reliability were a part of the bonus package under variable income. However, with external threats imminent a CIO’s primary salary plan includes the requirement of maintenance of a solid security protocol. Because of this paradigm shift in policies, the CIO could be regarded as the head of application security as online external threats continue to overwhelm organizational firewall servers. Just like the security guards that monitor an organization’s premises for people that a surveillance would miss, a CIO or an information security manager would be responsible for restricting prevalent threats to an organization’s data.

Other cases of irregular application security:

• Gov
• Airline ticketing systems
• Knight Capital Trading

Failure to follow the protocol would not only lead to a massive loss for the organization, but also to the employee as it directly affects the salary premium and more importantly, could cost the CIO their job.

Considerations when Choosing an IoT Platform Provider

Internet of Things (IoT), the latest advancement that Information Technology has to offer is now upgraded from a simple self-built IoT stack to a conglomerate market of various IoT platform providers. This transformation resembles the changes observed with cloud computing. What started as a single independent unit is now a market with several providers and service seekers. It is easier to build an IoT product using IoT platform providers on a pre-existing platform.

Things to consider:
Secure Product
A novel piece of technology is interesting and its development can always be rushed into so as to cater to the needs of the market. Many of such IoT devices experience the same hastiness that leads to a drop in security management. Security management is an important aspect as IoT at its core is an integrative platform. Risking security for functionality is not a prudent choice especially for IoT platform providers.
Secure Service
Another aspect of consideration is the integrity of security through the entirety of the software development life-cycle. Ensuring security only at the final product stage is not sufficient and has to last the entire development chain. As smaller companies cannot afford most of the resources required for consistent monitoring of the security, they integrate with other service providers. Only with a secure IoT platform will software providers and products experience enhanced security through the entire course of the software development life-cycle.
Returns
Returns always matter, especially when they are returns on a high investment. A standard term used in the business of anything, returns on investment (ROI) is a simple equation that balances out the cost and profits. Different providers have different ROI parameters. These parameters might be inconsistently priced. For example, one platform charges for the device whereas the other charges for usage and storage. For this very reason, recruitment costs and implementation costs need to be estimated and proportioned.
Maturity
The maturity of a platform is an indicative of its comprehensiveness in direction directly affecting its functionality. Security and Returns should be given lesser importance when considering IoT platforms in comparison to maturity of the platform. This is because of certain critical aspects that have long-term effects not just on the product software but also on IoT industry.

Type of support
Support is critical to any IoT product especially in critical stages of planning, development, and production. Records and references in the form of documents have very little significance when compared to support, guidance, and hands-on experience. In the production stage, a solid support would increase the efficiency of operation and minimize outages.
• Critical reviews
If the platform has been accepted by most of the experienced peers in the IoT industry, it probably has been through every test, scrutinized heavily, and deemed worthy of use.
• Performance
At the end of the day, the platform must present itself as a useful asset for the user. All the features, when tested, should deliver as a whole and be suitable for applications.
• Plot holes
Not every mature product is perfect. The fallacies in the product feature should not have a major effect on the performance of the IoT application.

Custom Software Solutions for the Oilfield Services

Oilfield services, one of the largest industrial sectors that have reported immense growth in the last decade, are responsible for maintenance of bulk datasets. Oil and gas plants that cover a major portion of the energy companies are required to handle complicated, intricate data sets that involve subcontractors, staff, and suppliers. With an increase in the costs, oil and gas companies have resorted to increasing their efficiency to compensate. To increase product efficiency in exploration and production services, operators are developing automation technologies for procurement and scheduling processes. For smooth operation of automotive technology, there is a requirement of software solutions that cater specifically to the service sector of oil and gas.

Driving Forces for Custom Software Solutions:

Apart from a better operational ability, the utility of equipment is also enhanced with software solutions leading to greater profits from an increase in production while not compromising on the budget. The specific costs that are targeted are the operational costs, which are known to substantially limit profits. The solution to limit those costs is in customized software solutions. These tailored software solutions ensure an increase in field performance efficiency enabling the organization to grow faster and expand to better horizons in the hydrocarbon sector by generating demand.

The tailored software solutions developed for the processing sector help the oilfield sectors increase operational efficiency in various operations, one of the major driving forces for adopting software solutions. Production and performance in oilfield services utilize software solutions for analysis to optimize their parameters without investing a major portion of their annual budget, this is possible through analysis of a large collection of data that is accessible through tailored software solutions.

Example: A multinational universally renowned oil and gas company, is an example of an organization that utilized the resources of customised software solutions to analyze geographical data produced from seismic sensors for improving their production and performance.

Another aspect of customized software solutions is through mobile wherein company personnel can communicate easily and take important decisions without having to invest a lot.

Note: For taking mobile software to the next level and develop cloud-based computing software to perform operations online would require a significant investment of time and money.

As these software solutions are customized to suit various requirements of different sectors under oilfield services, they can be offered on a per-case basis. Based on requirements, the solutions can either feature resource management, production cycle monitoring, data collection, cost accounting services, etc. Smooth handling and faster processing of processes that are more complicated is possible through tailored software solutions.

Present Scenario:

As more services are looking to increase their operational efficiency, the investment in these software solutions is increasing. Major countries in Europe and the minors in countries like Africa and Latin America are recruiting the services of tailored/custom software solutions for improving their production through better recruitment of resources, exploration abilities, and faster processing in oilfield services.

Business Requirement Analysis and Why It’s Important

We can’t control customer behaviour. But what we can control is our approach. Today, we talk about : Business Requirement Analysis and Why It’s Important

Many people embarking on a new project will ask why business requirements analysis is needed. Some may even advocate just “getting started” on the project – a very tempting proposition when the budget has been approved and the project team is enthusiastic and ready to go. But Business Requirements must be documented to ensure the agreement of all parties involved and that the final product meets the needs of the business and delivers a discernible, measurable improvement.

First, there is a set of knowledge someone should have to do analysis on some projects, but it depends on what you are building for who. In other words, it makes a big difference if you are modifying an enterprise application for a Fortune 100 corporation, building an iPhone app, or adding functionality to a personal webpage.

Second, there are different kinds of requirements.

• Objectives: What does the user want to accomplish?
• Functional: What does the user need to do to reach their objective? Non-functional: What are the constraints your program needs to perform within
• Business rules: What dynamic constraints do you have to meet?

Third, the ways to gather requirements most effectively can be:

• Read the agile manifesto – working software is the only measurement for the success of a software project
• Get familiar with agile software practices – study Scrum, lean programming, xp etc – this will save you tremendous amount of time not only for the requirements gathering but also for the entire software development lifecycle
• Keep regular discussions with Clients and especially the future users and key-users
• Make sure you talk to the Persons understanding the problem domain – e.g. specialists in the field
• Take small notes during the talks
• After each CONVERSATION write an official requirement list and present it for approving. Later, it would be difficult to argue against all agreed documentation
• Make sure your Clients know approximately what are the approximate expenses in time and money for implementing “nice to have” requirements
• Make sure you label the requirements as “must have”, “should have” and “nice to have” from the very beginning, ensure Clients understand the differences between those types also
• Integrate all documents into the latest and final requirements analysis (or the current one for the iteration or whatever agile programming cycle you are using …)
• Remember that requirements do change over the software life cycle, so gathering is one thing but managing and implementing another
• KISS – keep it as simple as possible

Last but the most important, get feedback!

Ways to Improve and Enhance Your Application Maintenance and Support Program

As an enterprise that deals with software development, alternating between the market’s requirements that are ever in flux is one of the problems that have a major effect on productivity. Gaining and staying competitive is one of the most crucial aspects of software development. As application developers, it is important to meet the specific requirements of a client and ultimately aid in the conversion of resources to products. However, without strategy and planning, the conversion is on the harder side and requires dedication. This article will highlight the ways to improve and enhance your application maintenance and support program.

Alter the defect tracking process

Defect tracking is similar to debugging as it basically involves tracking of errors made in an application. As the process starts from the origin point and goes through the end, it can be utilized for assessment and tracking of errors. The process of tracking errors involves meticulous recording, scrutinizing, clarifying, feedback reporting, and then as a culmination, rectify the problem. Even though it may seem cumbersome, the process is very useful and is can easily enhance application maintenance and support.

Testing and Reporting

Obvious and unavoidable means of application maintenance is to test and report defective codes or any changes that have to be reported. As an application is exposed to an environment in flux, like the technological operating system front, there will be many changes to be made post-testing. Testing and reporting are completed in two stages, the first stage has the test of modifications and updates made to the application. Following the first, the second stage involves checking for proper system function post-rectification.

Keep on updating

The continuous update of applications is possible in the form of support packages released by the publisher of the application. These support packages to aid in proper maintenance and support of your line of work. These packages are implemented to ensure that any bugs are rectified and do not emerge again in the code. Generally, bug fixes, new code, troubleshooting tools, upgrades are supplied through these support packages.

24×7 Maintenance & Support

One of the most effective ways to ensure that application maintenance is productive is through dedicated support unit. Certain applications require support to assist users all throughout the day across the world. Round the clock, support is a service strategy of the advanced level and has shown higher rates of success.

To conclude

These practices can increase rates of satisfied users for software applications as the problems are counteracted on even before they are noticed, and in cases where they are, the rectification is done immediately.
