Summary of What Are Databases and Why Do We Need Them?
Databases are designed to solve problems related to storing and managing Data.
Having Data is not the main problem; issues such as Size, updating, accuracy, Security, Redundancy, and integrity of Data arise.
Spreadsheets and Text files may work for small amounts of Data but become inefficient as Data grows.
Problems with Spreadsheets include slow speed, difficulty in updating, lack of Data accuracy, Security concerns, Redundancy, and Data integrity issues.
A database is required to prevent these issues and allows for efficient Data storage, modification, validation, Security control, tracking of changes, Data backups, and recovery.
