Application Architecture Design: Introduction

In the previous article, we became acquainted with the typical structure of a technical specification. We are now handing the specification over to the development department.

After the technical task has been handed over to the development team, it is necessary to translate it into a more technical language. This process is called architecture design.

View this process as the process of building architecture for a building. Building without an architectural solution is a failed endeavor.

The stages of designing architecture include

Application architecture design consists of the following steps:

1. Choosing a suitable architecture based on the requirements of the TOR. At this stage, a suitable product architecture is selected. We will talk about the main types of architectures in the next publication.

2. Creating a map of the interaction of architecture elements. It's like a map of user interaction with the application interface, only instead of interface elements, elements of the product architecture: databases, microservices, modules and others.

3. ER diagrams construction. This is a diagram that reflects the database structure of the entire product.

4. Building UML diagrams. A graphical representation of classes, objects and relations between them in the system is formed. 

In simple terms, the result of paragraph 3 is taken, individual components of the architecture are superimposed on it. Its functions are described for each overlay.

5. Formation of the final documentation. The results of the previous stages are formed into a single documentation, which is approved by the customer.


There is always a choice, skip this stage and go straight to development, or sacrifice finances and time in favor of getting a better IT solution.

This choice depends on various factors: budget, timing and scale of the product. 

If you need a simple web application consisting of 2-3 pages, then you can skip the design process, or do it in parallel, taking into account future functions. 

If you are going to develop a large IT solution from scratch, or upgrade an existing one, then I do not recommend neglecting this stage.
