What Is Database Architecture Explain With Diagram Design Talk

Types of DBMS Architecture. Database architecture can be seen as a single tier or multi-tier. But logically, database architecture is of two types like: 2-tier architecture and 3-tier architecture. 1-Tier Architecture. In this architecture, the database is directly available to the user. It means the user can directly sit on the DBMS and uses it.
