Study Notes
Data vs. Information
- Data refers to raw, unorganized facts and figures, while information is the result of organizing, analyzing, and interpreting data to extract meaning and value.
Value of Databases
- Databases are valuable assets for decision making because they provide a centralized repository of organized data, enabling efficient storage, retrieval, and analysis of data to support informed decision making.
Database System Components
- A database system consists of three main components: hardware, software, and data, which work together to store, manage, and provide access to data.
Functions of Database Management System (DBMS)
- A DBMS performs several key functions, including:
- Data definition, which involves defining the structure and organization of data
- Data manipulation, which involves adding, modifying, and deleting data
- Data querying, which involves retrieving and extracting specific data
- Data security, which involves protecting data from unauthorized access and use
- Data backup and recovery, which involves ensuring data availability and integrity in the event of system failures or errors.
