Centralized Database

Definition

• A type of database architecture where all data is stored in one central location, typically a server.
• Users access data by connecting to the server through a network.

Key Functions

1. Data Storage

   • Stores large amounts of data centrally.
   • Data includes customer info, product details, financial records, etc.
   • Structured format for easy access and retrieval.

2. Data Management

   • Tasks include adding, updating, and deleting data.
   • Provides tools and functionalities for efficient management.

3. Data Security

   • Security features protect against unauthorized access (encryption, access controls).

4. Data Access

   • Accessible through web-based applications, mobile apps, etc.
   • Tools for quick and easy data retrieval.

5. Data Analysis

   • Uses tools and technologies to extract insights and trends.
   • Helps in informed decision-making and operations improvement.

Examples

• Organizations: Store and manage employee info for HR purposes.
• Healthcare Providers: Store patient records and billing info for better patient care.
• Banks: Manage customer account info and prevent fraud.
• Online Retailers: Manage product info, orders, and shipping details.
• Government Agencies: Store tax records, voting data, census info for analysis and service improvement.

Advantages

• Easier management and maintenance due to centralized data.
• Better performance for certain applications due to reduced network traffic.
• Simplified access control with set permissions.

Disadvantages

• Single point of failure: Server issues can disrupt data access.
• Potentially higher implementation and maintenance costs.
• Requires a powerful server and regular upgrades to handle data and users.

Conclusion: Centralized databases are beneficial for efficient data management and quick access but come with risks like single points of failure and higher costs.
