1. Introduction to Databases

An introduction to databases involves understanding their role in storing, organizing, and managing data. Databases are structured collections of data that enable efficient retrieval, insertion, updating, and deletion of information. They serve as the foundation for various applications, from simple contact lists to complex enterprise systems. Key concepts include tables, which organize data into rows and columns; relationships, which define connections between tables; and SQL (Structured Query Language), used to interact with databases by querying and manipulating data.

What is a Database?

As mentioned, A database is a structured collection of data that is organized and stored electronically in a way that allows it to be easily accessed, managed, and updated. It typically consists of one or more tables, each containing rows and columns, where each row represents an individual record and each column represents a specific attribute or field of the data. Databases are commonly used in various applications and industries to store and retrieve information efficiently. They serve as a central repository for data that can be accessed and manipulated by users and applications as needed.
