Relational Database Management System (RDBMS);Definition of terms.

1. Database: A collection of structured data, typically stored electronically in a computer system.

2. Field (Column): A column in a table that holds a particular type of data, such as a text string or a number. Each field in a table has a unique name.

3. Record (Row): A single row in a table, consisting of a related group of fields (columns).

4. Primary Key: A unique identifier for a record in a table. A primary key must contain a unique value for each record and cannot be null.

5. Foreign Key: A field or collection of fields in a table that is used to refer to the primary key of another table.

6. Index: A performance-tuning method used to speed up data retrieval.

7. Join: A way to combine rows from two or more tables based on a related column between them.

8. SQL (Structured Query Language): A programming language used to manage and manipulate relational databases.

9. Normalization: A systematic approach of decomposing tables to eliminate data redundancy and improve data integrity.

10. Schema: The structure of a database, including all its tables, fields, and relationships.

11. CRUD: The basic operations that can be performed on a database: Create, Read, Update, and Delete.

12. Integrity Constraint: A rule that must be enforced on a database table to maintain data consistency and integrity.

13. ACID Properties: A set of properties that guarantee reliable and consistent transaction execution. These characteristics include durability, isolation, consistency, and atomicity.

14. Transaction: A single unit of work performed by a database management system, which can include multiple operations (e.g., inserting, updating, or deleting records).

15. Concurrency Control: A technique used by a database management system to manage simultaneous transactions and ensure data consistency and integrity.

16. View: A virtual table based on the result-set of a query.

17. Stored Procedure: A set of SQL statements stored in a database, which can be executed as a single unit.

18. Trigger: A special kind of stored procedure that automatically executes (or “fires”) in response to a specific event, such as the insertion or deletion of a record.

19. Function: A set of SQL statements that can be called within a SQL statement and can return a value.

20. Operating System: A software system that manages computer hardware, software resources, and provides various services for computer programs.

21. User: An individual who uses a database system.

22. Owner: A database user who has administrative privileges for a particular database object, such as a table or a view.

23. User Role: A group of database users that share the same set of privileges.

24. Server: A computer program that provides resources and services to other programs, such as database clients, over a network.

25. Client: A computer program that accesses the resources and services provided by a server over a network.

26. Backup: A copy of a database, usually created to ensure data integrity and security in case of system failures.

27. Recovery: The process of restoring a database to a consistent state after a system failure.

28. Restore: The process of replacing a database with a backup copy, usually done to recover from a system failure.

29. Admin: A user who has administrative privileges to manage and configure a database system.

30. Script: A sequence of SQL statements or commands that can be executed to perform a specific task.

31. Module: A software component that provides a specific function or feature within a database system.

32. Database Engine: The core component of a database system responsible for processing SQL commands and managing the database files.

33. Driver: A software component that allows a client program to interact with a database system through a specific interface or protocol.

34. Connector: A software component that allows a client program to connect to a database system.

35. Blob (Binary Large Object): A type of field that can store large binary data, such as images or documents.

In the upcoming database management system tour, numerous additional terminologies will be covered.
