Study Notes
Database Management Systems (DBMS)
- Databases store structured data using tables and fields.
- Databases save physical space compared to paper records.
- Multiple users can access the same data simultaneously.
- Queries (filters) allow retrieving specific data.
Data vs. Information
- Data is a collection of facts, meaningless on its own.
- Information puts data into context, making it understandable.
Database vs. Spreadsheet
- Spreadsheets manipulate data with formulas and calculations.
- Databases store data, often with relationships between tables, and allow user-friendly queries.
- Databases generally hold more data than spreadsheets.
Database vs. Information System
- A database can be part of an information system's backend.
- An information system (IS) handles collecting, processing, storing, and distributing information.
- Includes aspects of task, people, structure, and technology.
- The database provides data used by the information system, which then transforms the data into useful information.
Database Management System (DBMS)
- Software managing a database.
- Can encompass various software/applications (complete DBMS) or a single software (basic database).
- Provides data manipulation tools, security, and built-in data validation.
Data Consistency and Integrity
- Data consistency ensures data within a category is in the same format.
- E.g., date of birth formats (DD/MM/YYYY vs. MM/DD/YYYY).
- Data integrity ensures data is correct, relevant, accurate, and up-to-date.
- Use input methods (like calendars and drop-down menus) to improve data consistency.
- Validation rules within the database enhance consistency.
- Example: using drop-down lists in input forms to control data format and reduce errors.
Database Transaction
- A series of steps to make a single change to the database (update, delete, add).
- Includes ensuring data consistency, running validations, and checking data integrity.
