Study Notes
Database System Overview
- Five components of a database system include: Hardware, Software, People, Procedure, and Data.
- Raw facts are unprocessed data awaiting utilization.
- Information is processed raw data that becomes useful for the user.
- Knowledge is the compilation of relevant information and facts on a specific subject.
Importance of Databases
- Databases manage vast and varied data efficiently.
- They serve as organized electronic filing cabinets to store and manage data.
Database Structure
- A database consists of two primary data types:
- End-user data (raw facts)
- Metadata (data about data).
- Metadata details include the name, type of values (numeric, dates, text), and attributes of each data element.
Database Management System (DBMS)
- A DBMS is a set of programs designed to manage database structure and control data access.
Advantages of Database Management Systems
- Improved data sharing ensures users can access the same data resources.
- Enhanced data security protects sensitive information.
- Facilitates better data integration across various systems.
- Minimizes data inconsistency through centralized management.
- Improves data access speed and efficiency.
- Leads to enhanced decision-making based on accurate data.
- Increases end-user productivity by simplifying data manipulation.
Disadvantages of Database Management Systems
- Higher operational costs due to the need for specialized software and hardware.
- Increased management complexity requires skilled personnel.
- Necessitates ongoing maintenance for data accuracy and relevance.
- Potential vendor dependence on specific DBMS providers.
- Frequent upgrade and replacement cycles can be necessary for modern standards.
Database Types
- Single-user Database: Operates with only one active user at a time.
- Desktop Database: A single-user database that runs on a personal computer.
- Multi-user Database: Supports multiple concurrent users.
Specialized Database Types
- Distributed Database: A logically related database spread across two or more physically independent sites.
- Cloud Database: Maintained using cloud services like Microsoft Azure or Amazon AWS.
- General-purpose Database: Contains a wide variety of data applicable across multiple disciplines.
- Discipline-Specific Database: Focuses on data relevant to specific subject areas.
- Operational Database: Also known as Transactional or OLTP Database, supporting everyday transaction processing.
