We have become accustomed to the fact that the applications for business automation are by default ready systems, in which the necessary functions are modified. This approach is justified in most cases, but not always. If existing solutions have extremely complex functionality, and we only need a few business functions, it is much easier to write an internet application from scratch (WebApp or Web application such as this MRP for Small Manufacture).
Let's start with the definition in Wikipedia: "Web-based applications — client-server applications, in which browsers are clients, and servers are web servers on different platforms. Web application logic is distributed between the server and the client, all the data is stored mainly on the server, information exchange takes place over the network. One of the advantages of this approach is the fact that the clients do not depend on a specific user’s operating system, so web applications are cross-platform services".
Let's look at some aspects of defining the term "application":
Client-Server Applications
In this architecture, a browser or mobile application is used as user's working place. The advantage of this solution is that there is no need for any configuring on end user's working place. An end user can sign in independently or it is enough to send him an application link and (if necessary, depending on how the authorization have been resolved) his login and password.
One of the modern programming languages with different application architecture designs can be used as a solution back end. We use .Net and Node.js in our projects as server platforms.
Why .NET?
We will not go in depth in ‘complicated IT-terminology’. We will only provide answers from Quora (Quora is the most authoritative platform, that concentrates opinions of experts from all over the world):
python or .NET?
Quora: what is better and in which cases? .NET serves in an excellent way for creation of reliable and large scale corporate applications (when Python is better to use for data analysis and machine learning).
Php or .NET?
Quora: What is better and when? For corporate business applications .NET is сertainly better. (php can be used for development of small applications, mainly to interact with the final consumer/customer).
ASP.NET is the best choice for development of applications on automation of business-processes and on resolvement of business tasks at large organisations (there, where business users interact internally within the company, and externally with suppliers/ intermediaries/buyers). It is also the best for development of corporate applications for medium-sized business.
Web Application Logic
In the definition, we see that the logic is distributed between the server and the client, all data is stored mainly on the server, information exchange takes place over the network.
Tо begin with, Web application logic can be distributed in different ways. We can store only data on the server, and all the logic of user's work can be implemented into user’s application, the code of which we can receive from the server if we work through a browser. The code can also be implemented into the application if we use our mobile client. In other case, we can provide the user with already generated HTML page from the server and rebuild it with each user action.
In modern back-end solutions, the REST service of data storage and, partially, business algorithm storage is often implemented. A browser application addresses this REST service for required information. There is an example of this solution in our article on CRM (Small Business), product, developed for our customer Select Sport. In the same article, you can go to the demo baza.
All data is stored mostly on the server, but it can be also stored locally as browser cache or in a mobile application in case there is no connection or the server is unavailable for some reason.
Benefits of Web Applications
Custom clients are independent of hardware and don’t need any configuring. The process of connecting a new user ends with providing him a link to the application and (depending on business requirements) his login and password or he can sign in independently. Otherwise, the application does not require any user identification at all.
Speed of work - Web applications built on this architecture have very high performance. The number of concurrent users can number in thousands. Often, ready-made desktop solutions, as well as solutions with a metamodel embedded in their architecture, have difficulties with exponential growth of users and data processing.
No need to license each client individually when creating a Web application from scratch, and Linux laptops do not require any expenses for connecting a new working place (except for the hardware itself).
Disadvantages of Web Applications
As for any solution, one can not evaluate only its advantages, it is necessary to understand the risks associated with choosing such a solution.
When creating a Web application from scratch, you are partly tied to a company-developer of this solution. The change to another developer results in additional expenses for studying the solution architecture by a new partner. Moreover, many of us have often heard: "They did everything wrong."
Often, although not always, writing an application from scratch is more expensive because of the necessity for creation of typical objects already existing in box versions of software solutions. Sometimes it is justified, and sometimes not.
Frequently Asked Questions
Where is data stored?
Data can be stored either in a cloud in leased space or on your servers in a local network.
What can we do, if we already have an IT system, and we need to modify a small set of tasks and functions?
It depends on a situation. Sometimes it is easier to modify the existing system, and sometimes it's better to move functionality out of the existing system. We solve such problems successfully, integrating individual services by using
Genumis integration platform.
Do you have any questions on architecture and implementation of WEB applications for your business ?
We create Web applications with complex business logic using our working experience with ERP-class systems, integrating software complexes into a single information space. We solve synchronization and data exchange tasks.
OUR EXPERIENCE OF ERP IMPLEMENTATION IS OUR BENEFIT IN DEVELOPING FUNCTIONALLY COMPLEX WEB APPLICATIONS FOR B2B AND B2C.
