Why to Learn DBMS?
Historically, data was structured in file formats. The concept of a Database Management System (DBMS) was revolutionary at that time, with extensive research conducted to address the shortcomings of the conventional approach to data management. A contemporary DBMS embodies the following key features Enhanced Realism: A modern Database Management System (DBMS) incorporates real-world entities into its architecture, capturing both their behaviors and attributes. For instance, in a school database, students are treated as entities with attributes like age.

For instance, in a school database, students are treated as entities with attributes like age. Structured Relationships: DBMS organizes entities and their relationships into tables, allowing users to comprehend the database architecture simply by examining the table names. Data-Application Separation: DBMS distinguishes between the database system itself and the data it manages. While the database actively processes and organizes data, the data itself remains passive. Additionally, DBMS stores metadata, facilitating its operations. Reduction of Redundancy: By adhering to normalization principles, DBMS minimizes data redundancy. Normalization, a rigorous and scientific process, breaks down relations to eliminate redundant attribute values. Ensured Consistency: DBMS ensures consistency across all database relations. Various methods and techniques are employed to detect and prevent actions that could lead to an inconsistent database state. Compared to older file-processing systems, DBMS offers superior consistency. Robust Query Language: DBMS features a query language, streamlining data retrieval and manipulation. Users can apply diverse filtering options to retrieve specific data sets efficiently—an operation not feasible with traditional file-processing systems.
