Introduction to IBM Db2: Understanding the Basics of a Database
What is IBM Db2?
IBM Db2 is a relational database management system (RDBMS) developed by IBM that offers a comprehensive platform for storing, managing, and analyzing structured and unstructured data. It is designed to provide high levels of performance, scalability, and reliability for enterprise-level applications. Db2 has been in existence for several decades and has evolved to become a robust and widely-used database technology.
Key Concepts of Database Technology
To understand IBM Db2 better, let’s explore some fundamental concepts of database technology.
1. Relational Database:
A relational database is a type of database that organizes data into tables, which are composed of rows and columns. It establishes relationships between tables using common attributes, enabling efficient storage, retrieval, and manipulation of data.
2. Structured Query Language (SQL):
SQL is a programming language used to manage and manipulate data in relational databases. It allows users to create, modify, and retrieve data using a set of standardized commands, such as SELECT, INSERT, UPDATE, and DELETE.
3. Database Management System (DBMS):
A DBMS is software that provides an interface for managing databases. It facilitates data storage, retrieval, security, and administration, ensuring data integrity and enabling efficient data management.
