Study Notes
Traditional File Systems
- Before computers, manual file systems were used to store data, which involved physical files for easy retrieval of information.
- Traditional File Systems were introduced to overcome the limitations of manual systems.
- Traditional File Systems stored data in separate files for each department or function, leading to data redundancy.
Data Redundancy in Traditional File Systems
- Example: Student data stored in separate files for library, exams, and registration, leading to duplicated student information (name, number, etc.).
Traditional File Systems Pros and Cons
- Advantages: Simple functionality suitable for small businesses and home users; less expensive.
- Disadvantages: No multi-user access support; limited to small organizations; limited functionality (lack of complex transaction support, recovery, etc.); data decentralization; redundancy and integrity issues.
Database Approach
- Centralizes data storage within a single database.
- Database is physically stored in files, but users and applications interact with an abstract view of the data.
- Relationships between data sets are represented within the database.
- Database description (schema) is stored along with data, allowing Database Management Systems (DBMS) to retrieve and store data efficiently.
- Applications don't directly access the database; they interact through the DBMS.
Traditional vs Database Approach
- File Management Systems (FMS) are predecessors to Database Management Systems (DBMS).
- FMS allowed access to single files, while DBMS facilitates access to multiple files or tables at a time.
- FMS works with flat files, while DBMS manages relational data.
Advantages of Using a DBMS
- Eliminates data redundancy during storage and development/maintenance.
- Enables data sharing across multiple users.
- Restricts unauthorized access to sensitive data.
- Provides efficient storage structures for data retrieval through queries.
- Offers data independence, separating data representation and storage from user interaction.
- Facilitates efficient data access through various storage and retrieval techniques.
- Enforces data integrity constraints.
- Manages data administration, treating data as a valuable organizational resource.
- Supports concurrent access and crash recovery, allowing multiple users to access data without conflicts and protecting the system from failures.
- Reduces application development time by providing common functions required across applications.
Database Users
- Categorized as actors on the scene (those who use and control data) and workers behind the scene (those responsible for developing the database and DBMS software).
