Study Notes
Database Concepts
- Databases store user data and metadata
- Data is raw facts, while information is processed data
- Databases are crucial for decision-making in various modern settings, like business, research, and administration
- Databases evolved from file systems, addressing limitations in managing data effectively
- Database design is vital for efficient data management, avoiding redundant data, and creating accurate information
- A Database Management System (DBMS) manages database structure and controls access to data, making data management more efficient
- DBMS functions include data dictionary management, storage management to store data and associated forms, reports, data transformation and presentation in a suitable format.
- DBMS guarantees security and data privacy; multi-user access control; and backup and recovery procedures
- Database types categorized by user count: single-user (desktop) and multi-user (workgroup, enterprise)
- Database types categorized by location: centralized (single site) and distributed (multiple sites)
- Database types categorized by use: operational (OLTP) and analytical (data warehouse)
- DBMS handles user requests through access languages and application programming interfaces, allowing efficient data retrieval from complex systems
- Database system contains hardware (physical devices), software (operating system, DBMS, application programs/utilities), people (users, administrators, designers, analysts, programmers), procedures (instructions governing the database system), and data (stored facts)
- File systems' limitations include complexity, ad-hoc queries, difficulty adapting to changes in file structure, inadequate security, data redundancy, and data anomalies
- Data dependence and structural dependence are limitations in file systems, where changes in data attributes or file structure require modifications in various application programs.
- Data anomalies (update, insertion, deletion) lead to data inconsistency and integrity problems in file systems
- Modern end-user productivity tools (like spreadsheets) can present similar limitations as older file systems
