Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.

Memory (sometimes called address space) is set aside before a programme is run so that it may store its instructions, data, and structures. Pre-execution is the stage before a programming is actually run. the act of piling or stacking something. In addition to the maximum number of stacks and heaps that may be utilised by a single process, please describe the functionality of these data structures.
