andmebaasisüsteemis

An andmebaasisüsteem (DBS) is a collection of interrelated data that is organized and stored in a way that allows for efficient access, management, and updating. It consists of a database, which is the actual collection of data, and a database management system (DBMS), which is the software that interacts with the database to perform operations such as data retrieval, insertion, deletion, and updating.

The primary purpose of a DBS is to provide a structured and efficient way to manage large amounts of data. It ensures data integrity, security, and consistency by enforcing rules and constraints on the data. This makes it easier to maintain and update the data, as well as to retrieve specific information when needed.

DBSs are used in a wide range of applications, from simple personal databases to complex enterprise systems. They are particularly useful in environments where data needs to be shared among multiple users or applications, as they provide a centralized and controlled way to manage and access the data.

The design of a DBS involves creating a database schema, which defines the structure of the data, including the tables, fields, and relationships between them. The DBMS then uses this schema to manage the data and enforce the rules and constraints defined in the schema.

In summary, an andmebaasisüsteem is a crucial tool for managing and organizing data in a structured and efficient manner. It provides a centralized and controlled way to store, retrieve, and update data, making it an essential component of many modern applications and systems.
