What are the advantages and disadvantages of a two-tier architecture system?

Two-tier architecture (client-server) is characterized by a division into two levels: the client interface and the server with a database.

Advantages:

• Simplicity of implementation and support.
• Rapid development for small applications.
• Fewer components, which reduces complexity.

Disadvantages:

• Limited scalability as load increases.
• Client and server are closely linked, reducing flexibility.
• Security and access management can be challenging.
• Difficulties in implementing complex business logic, as it is often concentrated on the server.

Thus, two-tier architecture is suitable for simple and small systems but can become a bottleneck when scaling and complicating the application.
