A Database Management System (DBMS) is software that is used to create, manage, and manipulate databases and provides users and programmers with a systematic way to create, retrieve, update, and manage . It serves as an interface between the and its users or the application programs, ensuring that data is consistently organized and remains easily accessible. Key functions include: Data Storage, Retrieval, and Update, Data Security and Integrity, Data Administration, and Data Models.
The storage engine handles the physical storage of data on , performs data retrieval and manipulation operations, and ensures data integrity and consistency. It plays a central role in enabling users to create, read, update, and delete (CRUD) data efficiently and reliably. A data dictionary is a centralized repository of information about data such as meaning, relationships to other data, origin, usage, and format. It acts as a reference for the system to understand the structure, constraints, and relationships of the data.
A database management system (DBMS) user interface (UI) is the graphical or text-based interface that allows users to interact with the database. There are two main types of DBMS UIs: User Interfaces (GUIs) and Text-based Interfaces (TUI / CLI). There are many different types of database reports, but they can be broadly classified into categories such as Summary reports, Detail reports, Drill-down reports, Cross-tabulated reports, and tables. The backup feature in a Database Management System (DBMS) is a critical component for ensuring data integrity and continuity, allowing organizations to recover data after unforeseen events like system failures, data corruption, or accidental deletions.
