Basic concepts of three-tier architecture in software development

There are no software development companies that do not use a three-tier architecture or higher-level architecture.

For example, if your project team has three people.

If a layer-3 structure is used, the job can be split into one person as the UI Layer, one person as the data access layer, and one person as the business logic layer. Everyone is responsible for their own levels to ensure that their level design is good and maintainable, so as to achieve the overall design and maintenance of the project.
Otherwise, Division by function will lead to a large number of repeated data access objects and business processing objects, thus causing project structure accidents.

Therefore, the three-tier architecture has clear ideas and tacit cooperation among teams, making it easy to make a good decision.Program.
