Software architecture is a critical component of any software development process. It focuses on the structure of the application or system, including the way its components are organized and how they interact with one another. A software architecture has several distinct layers, each with its own purpose and responsibilities. In this blog post, we will discuss what these layers are and why they are important to consider when designing a software application. By understanding the various layers that make up a software architecture, you can create an effective and efficient application that meets the needs of its users. Furthermore, understanding the layers involved in software architecture can help developers identify potential bottlenecks, such as performance issues, during the development process. This blog post will provide an overview of the different layers of a software architecture and explain how they relate to one another and the overall application design.
- Presentation layer. The presentation layer, also called the UI layer, handles the interactions that users have with the software. …
- Application layer. The application layer handles the main programs of the architecture. …
- Business layer. …
- Persistence layer. …
- Database layer.
Why is it important to divide an application into layers?
The need to divide an application into layers can be attributed to a number of factors, including:
What are the layers in software architecture?
In software architecture, layers function as distinct processes within an application’s infrastructure. Typically, a pattern known as the n-tier architecture pattern is formed by these layers. For many applications, this is the industry standard, and many designers, engineers, architects, and developers are familiar with this idea. Each layer in the layered architecture pattern performs a particular duty and function for the application. Some deal with the execution of business rules, while others concentrate on user interface logic. Although they complement one another’s distinct functions, these layers are not explicitly dependent on one another to carry out their respective tasks.
In essence, the layered architecture pattern is made up of layers. Although there are no strict requirements for the number or type of layers in this pattern, most layered architectures are made up of four to five standard layers. However, the number of layers an application has depends on its size. Smaller applications, for instance, might only have three layers. Comparatively, larger, more complex applications can have up to five layers or more. Each layer only deals with the logic that applies to its own layer because there is a separation of concerns among the various layers.
5 layers in software architecture
Here are five main layers in software architecture:
1. Presentation layer
The user interface (UI) layer, also known as the presentation layer, manages user interactions with the software. Its most visible layer determines how an application will appear to users overall. Anyone can use this tier from a client device, such as a desktop, laptop, mobile phone, or tablet, making it the most widely available.
2. Application layer
The application layer handles the main programs of the architecture. It includes the code definitions and the developed application’s most fundamental features. When creating the software, programmers spend the majority of their time in this layer. This layer can be used to implement particular coordination logic that does not perfectly coincide with either the presentation layer or the business layer.
3. Business layer
Applications’ business logic operates at the business layer, also known as the domain layer. Business logic is a set of rules that instruct the system how to execute an application in accordance with the policies of the company. This layer essentially determines the behavior of the entire application. It instructs the application what to do next after one action has finished.
4. Persistence layer
The data access layer, also known as the persistence layer, serves as a safeguarding layer. It has the necessary code to access the database layer. Additionally, this layer contains the set of codes that let you control different aspects of the database, including connection information and SQL statements.
5. Database layer
The system stores all the data in the database layer. It is the bottom tier of the software architecture and contains tables and indexes in addition to data. Search, insert, update and delete operations occur here frequently. Application data can be stored on a file server or database server, revealing important information while concealing the methods used for data storage and retrieval.

FAQ
What are the 3 layers of architecture in step?
The four standard layers in most layered architectures are presentation, business, persistence, and database, even though the layered architecture pattern does not specify the number or types of layers that must exist in the pattern (Figure 1-1).
What are the types of layered architecture?
- The server that houses all of the application’s data is called the “Data Tier.”
- primarily serving as a link between the Presentation Tier and Data Tier
