MVC – Why it is better?

MVC is an acronym for Model, View, and Controller. It’s a product development architecture. The traditional approach of programming works on Input -> Process -> Output approach while MVC works on Controller → Model -> View.

During, the traditional approach of programming, the UI coding, business logic, and application data domain was written into a single file which creates a lack of maintainability, testability as well as scalability of the application.

With the emerge of MVC approach, it helps you create applications that separate the different aspects of the application (input logic, business logic, and UI logic), while providing a loose coupling between these elements. The pattern specifies where each kind of logic should be located in the application. The UI logic belongs in the view. Input logic belongs in the controller. Business logic belongs in the model. This separation helps you manage complexity when you build an application because it enables you to focus on one aspect of the implementation at a time. For example, you can focus on the view without depending on the business logic.

The MVC model or “pattern” is commonly used for developing modern user interfaces. It provides the fundamental pieces for designing programs for desktop or mobile, as well as web applications. It works well with object-oriented programming since the different models, views, and controllers can be treated as objects and reused within an application.

Below is a description of each aspect of MVC:

1. Model

A model is data used by a program. This may be a database, file, or a simple object, such as an icon or a character in a video game.

2. View

A view is the means of displaying objects within an application. Examples include displaying a window or buttons or text within a window. It includes anything that the user can see.

3. Controller

A controller updates both models and views. It accepts input and performs the corresponding update. For example, a controller can update a model by changing the attributes of a character in a video game. It may modify the view by displaying the updated character in the game.

IMPORTANT BENEFITS OF MVC MODEL

1. Accelerated Development Process:

How can you increase the development speed by adopting MVC architecture? Whenever an MVC architecture is being employed in developing a web application, one developer can concentrate on the view component whereas the other can focus on controller and create business logic. Therefore, when compared to other development models, the MVC model results in higher development speeds i.e. up to three times.

2. Develop Multiple View Components for your Model:

The MVC architecture empowers you to develop different view components for your model component. As you can witness an ever-increasing demand for new ways to access your web apps, MVC architecture is your one-stop solution for developing different view components. Also, the MVC model limits code duplication and separates the business logic and the data from the display.

3. Supports Asynchronous Method Invocation (AMI):

Undoubtedly, MVC architecture works cohesively well with JavaScript Frameworks. As a result, you can run MVC apps on desktop widgets, site-specific browsers, and PDF files. The MVC architecture supports asynchronous method invocation (AMI) that bolsters developers in building quick loading web apps.

4. Modifications do not Affect the Entire Model:

Your web app’s UI gets new updates every now and then than your actual business model/rules. These include optimizing the color, layouts, font family, font size, and additional support for mobile/tablets. As already said, since the model, view and controller are independent components, making changes in the MVC architecture is very easy. Moreover, making changes in the model component will not have any adverse effects on the architecture.

5. MVC Model Returns the Data Without Formatting:

You can use and call the same components and put them into use with many interfaces. For instance, you can format data with HTML.

6. Ideal for Developing Large Size Web Application:

MVC architecture works exceptionally well when your web app demands the support of a huge developer team, and for web designers who require complete control over the app’s behavior.

Therefore, MVC architecture is a one-of-a-kind approach to building web apps. As the MVC frameworks come packed with the above-mentioned advantages, it is easy to implement in your framework. The adoption of MVC architecture results in the lesser expense of time & money, and the ability to create multiple views makes it the best architecture for web app development.

Freelancer vs Agency: Who Should You Hire?

With every technology update and advancement, the world is coming in much closer and is bringing everybody together. For each and everything we see out there, there is a website or a mobile app related to it, be it a product or a service. The individuals or organizations working on these updates and advancements also need to be in sync with each other. In order to grow the business, they will need to put out more websites and mobile apps.

For these software developments, we need specialists to help us create the best possible product. If you need your car fixed, you go to a garage and get it fixed by the one who is an expert in cars. The same applies to the software development industry. You will have to find a professional you can trust with the design, development, and deployment of your software.

The important question is, how do you find the right fit at the right price? Would it be better to hire a freelancer to do multiple jobs or an agency with specialized skills?

Freelancers vs. Full-Service Agencies

Building a world-class website requires a team of experts with many areas of expertise. One person simply cannot do it all (or cannot excel in all areas). Why? Here is an example.

Would you hire just one person to build an entire house for you from the ground up: obtaining permits, architectural design, foundation, plumbing, electrical, roofing, painting and decorating? Can you imagine the finished home at the hand of one individual attempting to fulfill all these elements of construction? A world-class website, the kind of website that can actually achieve your business goals, is not a one-man job. It takes a small army of professionals, each with their specialty, working compatibly over an extended amount of time.

Step By Step Guide

  1. Successful business websites require business-minded project managers who can delegate projects effectively. They work with market research professionals who study the needs of your customers.
  2. Usability experts create user-centric experiences. Following this phase, art directors and designers transform these plans into effective designs.
  3. Coders and programmers convert designs into a functional website, which, in turn, is tested by quality assurance teams.
  4. Driving traffic to a website is the job of Search Engine Optimization (SEO) and Social Media Optimization (SMO) specialists.
  5. System administrators ensure the website is fully operational around the clock, and account executives manage client communications.
  6. Some projects may require additional services from photographers, illustrators, videographers, voice-over artists, post-production specialists, animators, data entry personnel, mobile marketers, IT strategists and security experts. The list of specialists grows depending on the complexity of the project.

If you hire a single individual to complete your entire project, it is likely they will have to outsource some of the tasks. If they focus strictly on cost-effective measures and cut corners on talent and resources, the unfavorable result will fall on your shoulders. You may find yourself managing efforts in an industry where you lack expertise.

Hiring an Agency

  1. Skills. An agency makes more effort at learning new skills. They constantly update themselves with new technologies and try to offer you the best possible tools for development.
  2. Consultation. Because you are working with a team here, you get tips and advice for almost every part of your project as the team will consist of people from different backgrounds with different expertise.
  3. Accountability. When you hire an agency, a project manager will be tasked to handle your freelancers. The project manager handles the team, tracks the hours, and provides feedback. It’s easier to go through a project manager who watches the team, than individually checking each freelancer. This gives you more time for other important things like client meetings. Also, you don’t have to worry about freelancers dropping your project. They can provide replacements if emergencies happen.
  4. More coordination. Handling one person can be extremely easy. But when there is a team that handles the whole project, you don’t need to worry about the coordination as the team will have different members assigned for different tasks and this is managed internally.
  5. Long-term work relationship. Finding the right team helps you take on more projects in the future. Since you already have a team with a set of special skills, you’ll be more confident to accept bigger projects.

Hiring a Freelancer

  1. Availability. Freelancers have flexible schedules. They are location independent and can work anywhere, as long as they have a strong internet connection. However, this can be a problem if you are in a different time zone from your freelancer. There might be times that he’s unavailable if you urgently need them.
  2. Work overload. A solo freelancer works for many clients. Sometimes, the tasks and deadlines pile up on his desk. This can affect the freelancer’s performance. The projects might be rushed and not properly done because they are too exhausted. This can bring less satisfying results.
  3. Looking for a replacement can be difficult. One of the common freelance hiring nightmares are workers who disappear or quit completely. Though a huge chunk of freelancers is reliable, emergencies happen sometimes. Certain factors and reasons can cause a freelancer to quit the project. You can hire a replacement in a breeze, but that means you need to go through step one again. Also, if the freelancer is already halfway in his work, it can be hard for the new freelancer to continue it.
  4. Managing multiple freelancers can be tough. If you need many specialists, you’ll need multiple freelancers. For example, if your project needs a writer, a coder, and a graphic designer, you need to hire three people. Handling them all at the same time can be a daunting task, especially if they live in different time zones.
  5. Less Control. When you work with an individual you will have to trust whatever information is provided to you. Sometimes the information given to you is outdated or not beneficial. But there is not much control over it.
  6. Confidentiality. Freelancers often don’t sign contracts. When there is no contract, there is also no non-disclosure agreement. Because of this, there are chances of your ideas and designs being leaked out.

Conclusion

Hiring an agency is advisable if:

  • The project is complex and requires multiple work streams and phases to manage.
  • Need multiple specialists.
  • Tight deadline.
  • You can’t manage multiple freelancers.
  • You are always busy and can’t always keep up with the team.

 

So, should you hire an individual freelancer or an agency?

What is a Payment Gateway and How Does It Work?

Online payments have become a part of our daily lives in no time. We’re transacting online not only through debit or credit cards but through numerous other modes like net banking, wallets, etc.

Online invoice payment helps companies save time, is faster and saves maximum efforts for the clients. It helps in reducing,

  • excessive costs involved in physical transactions
  • significant amount of paper invoices that will be printed and used to send invoices.

Online payments allow you to buy products and services from all over the world. If you are a seller, you can sell to anyone in the world with a decent internet connection. Your customer doesn’t even need to have a computer; a smartphone is enough.

But what exactly is a payment gateway? Is it safe to transact through a payment gateway? Does it make sense for your business to have a payment gateway integration? Let’s find out.

What is a Payment Gateway?

Payment gateways are software and servers that transmit transaction information to acquiring banks and responses from issuing banks (such as whether a transaction is approved or declined). Essentially, payment gateways facilitate communication within banks and plays the role of a third party that securely transfers your money from the bank account to the merchant’s payment portal.

How do payment gateways work?

The transaction flow is the same whether you’re using a physical or virtual payment gateway, but mobile and online payments use digital capture files for packaging the credit card information rather than output from a credit card reader:

  1. The buyer makes a credit card payment through the merchant’s credit card reader or e-commerce site.
  2. The payment gateway:
  • Pushes the transaction information to the acquiring bank (the merchant bank or acquirer)
  • Determines which credit card network (Visa, MasterCard, Discover, or American Express) issued the buyer’s card
  • Routes the transaction information to the correct payment switch
  1. The payment switch routes the request to the bank that issued the buyer’s credit card (the issuing bank) and pushes the transaction information onto the correct credit card network.
  2. The issuing bank applies fraud detection procedures to determine the legitimacy of the transaction and confirms the buyer has sufficient credit in their account to accommodate the purchase.
  3. The issuing bank approves (or rejects) the transaction and sends this information back through the credit card network to the merchant bank and the payment gateway.

Security Standards

Security is an integral component of all payment gateways, as sensitive data such as credit card numbers need to be protected from any fraudulent parties. The card associations have created a set of rules and security standards that must be followed by anyone with access to card information including gateways. This set of rules and security standards is called the Payment Card Industry Data Security Standard (PCI-DSS or PCI).

Submitting an order is usually completed using the HTTPS protocol, which securely communicates personal information through the parties involved in the transaction.

Opening Your Payment Gateway for Business

Once you understand the importance of a payment gateway and its impact on your sales and security, it’s time to take the next steps:

  • Research with key priorities in mind. Check the PCI compliance of your potential payment solution to ensure its security, and always look for per-transaction prices to get a sense of how a gateway will impact your bottom line.
  • Understand what your customers want. Even if you don’t have a payment gateway, there are insights you may already have that you need to leverage. Which payment services do your customers prefer, and what’s the most convenient way to facilitate these preferences?
  • Stack multiple gateways to fill gaps. You don’t have to commit to one gateway for the rest of your days. You can even stack multiple gateways at once to ensure maximum coverage for most customer needs.
  • Like with almost any service, there are fees associated with them. You’ll have to pay transaction fees for your business — so pay attention to your gateway’s costs and do your research before integrating it into your site so you’re not slammed with surprise fees.
  • Different fees charged can include transaction, statement, chargeback, merchant account fees, and likely more — such as fees to customers for using a certain payment method. And not surprisingly, customers do NOT like hidden costs so read the fine print.

With a better knowledge of price, function, and gateway security, your business will be in the position to choose the right option for your business needs and add a new level of security (and peace of mind) that customers need when making a purchase online.
