Hence, an n-tier DBMS Architecture divides the whole DBMS into related but n independent layers or levels, i.e., a one-tier architecture divides the DBMS into a single layer, a two-tier DBMS architecture divides the DBMS into two layers, a three-tier in three layers, and so on. These architectures follow a tier-based classification, i.e., the DBMS architecture is classified depending upon how many layers are present in the structure of the DBMS. Since a database management system is not always directly accessible by the user or an application, we can maintain it with the help of various architectures based on how the user is connected to the database. These modules/layers describe the functioning and the design of the DBMS. Types of DBMS Architectureĭatabase management systems are divided into multiple levels of abstraction for proper functioning. In this article, we will explore the different types of DBMS architectures along with their real-life examples. It describes the structure and the way in which the users are connected to a specific database system. The database management system design depends on the DBMS architecture for its representation. The DBMS architecture affects the performance of the database as it helps to design, develop, implement, and maintain the database management system. This concept is also true in the case of the database management system. This determines the structural integrity and durability of the entire complex, i.e., the architecture defines the structure's performance. While planning any structure, the architects design and develop the organization and the layout of the individual components used to build the whole structure and their relationships. This article provides an overview of the different types of DBMS architectures along with their merits and demerits. It also affects the performance of the database as it helps to design, develop, implement, and maintain the database management system. DBMS architecture describes the structure and how the users are connected to a specific database system.
