Study Notes
Understanding Databases and Data Management
- A database is an organized collection of structured information, typically stored electronically and managed by a Database Management System (DBMS).
- Data contributes to producing information by being processed, accumulated, and analyzed to generate meaningful insights and facts that support decision-making.
Modern Database Management Systems (DBMS)
- A modern DBMS aims to reduce data redundancy, ensuring that data is stored once and minimizing duplicate storage across different systems or tables.
- A characteristic of a modern DBMS includes support for transaction management, which provides data integrity and consistency during operations.
Traditional Data Organization
- Before DBMS, data was traditionally organized in flat files or spreadsheets, leading to challenges such as difficulty in managing large amounts of information and inconsistencies across various data sets.
