WEB APPLICATION DEVELOPMENT
Creation of web applications for smartphones, tablets and desktops is the best investment in the development of a company. These versatile solutions simplify and streamline business processes for both owners and customers. At the same time, all commercial data will be located in a fault-tolerant and secure cloud storage, and access to the necessary program functions can be easily obtained through a web browser on any device.
To meet the demands of the time and to withstand the competition, a company's web resources must open equally well and quickly on both desktop computers and mobile devices.
But a change in the approach to site layout does not in itself allow making a qualitative leap in business development. For online conversions to rise and metrics to skyrocket, interactivity is needed.
The organization's web resource should not provide static information at the user's request, but dynamically generate web pages with exactly the data that the client needs. That is why the creation of static websites, portals and landing pages is being replaced by the development of web applications.
FUNCTIONALITY AND ARCHITECTURE
Many sites and portals that we visit on a daily basis are in fact web applications. These are postal resources, social media pages, search tools, online banking systems, online stores, online editors, games and much more.
As mentioned, the key difference between web applications and websites is that they are not static data in the form of documents on the Internet, but executable programs. Web applications are client-server solutions that are stored on the server and run on the server and on the user's computer or smartphone.
The back-end of the web application is the main part of the program where the calculations take place. They are executed on the basis of users' internet requests sent through web browsers. Moreover, many clients can have access to the server side of web applications at the same time. Developers familiar with PHP, ASP, Perl, C / C ++, Java, Python, etc. technologies are involved in the development of the Back-end parts of web applications.
A web application database is a huge array of all kinds of information that a business needs. At the request of the user, the back end of the web application uses this data to process and provide it to the end client.
Thus, the development of web applications allows you to abandon the binding of a mobile or application program to any one platform - Windows, MacOS, Android or iOS. Web applications will work wherever there is a web browser and internet access.
SPA: SINGLE PAGE WEB APPLICATIONS
A special case of web application development, which today is an undoubted trend, is the creation of so-called "applications from one web page" (Single Page Application). They represent a resource (for example, a multi-page portal) from one web page, on which, depending on the user's actions, the necessary executable code is loaded in the form of program scripts and content. The server of such a web application can store thousands of files, documents, and program scripts, but only a few of them will run on the user's device.
Thus, traffic is significantly saved, since only those scripts and the content that the user needs are downloaded to the device, and not all software components of the web application. And at the same time, a universal solution for different devices is being created: a separate set of software scripts is downloaded for each smartphone, tablet or laptop. This approach to developing web applications makes it possible to run software solutions with a complex architecture and interface in an Internet browser that are not close to a standard website, but rather to an application program.
WHAT ARE THE ADVANTAGES OF WEB APPLICATION DEVELOPMENT
The main advantage that a business gets from developing web applications is a win-win strategy in relation to the owner of the Internet resource and to the client. The user gets a convenient, fast and affordable digital service, and the site owner gets a tool for automating business processes. The key advantages of web applications can be summarized in several theses:
cross-platform: web applications can be accessed from any device;
cost-effectiveness: the customer does not need to pay for the development of applications for different operating systems;
versatility: web applications do not require installation and updates;
performance: data is calculated on the server, and device resources are used to a minimum;
scalability: you can improve the quality of the web application (for example, with an increase in the number of users) by improving the server hardware;
security: user data is stored in the cloud on the server, not on the device;
interactivity: the interaction between the server and the client makes it possible to personalize the user and provide each individual with individual data;
consistency: web applications facilitate the work of the business and the receipt of services by the client.
HOW THE PROFESSIONAL DEVELOPMENT OF WEB APPLICATIONS HAPPENS
In order to order the development of web applications, it is enough to focus on the general scheme of software development that we use in our work. To do this, we apply a modern approach to project management using the SCRUM system. This development model assumes a flexible approach to creating digital services, divided into time intervals in the form of sprints of 1-2 weeks. At the end of each of the temporary iterations, the client can control the web application development process, making his own suggestions and adjustments.
The general development cycle of web applications includes such stages.
Analysis of business requirements and market situation is necessary to find out the target audience of a digital product, understand its functionality and check if there are competitors.
Drawing up a technical assignment: requirements for the development of a web application should be documented.
Prototyping web applications is a key stage that allows you to think through and visualize all the logic of a digital product.
Interface design development implies drawing graphic solutions that fully and conveniently correspond to the functionality of the web application.
Responsive web application layout is the implementation of interface design on different devices.
Programming the server and client parts of the program is the main stage in the development of web applications.
Testing of web applications is necessarily carried out not only at the stage of the final release, but also during the development process.
Launching and technical support implies placing a web application on the customer's server with the subsequent maintenance of the resource.
In addition to the direct development of web applications, we are also ready to provide services to promote a new digital service.
WHY IT IS WORTH ORDERING THE DEVELOPMENT OF WEB APPLICATIONS IN OUR COMPANY
We are ready to design and develop web applications such as:
