PC Databases

Examples of PC databases include Access, SqlServer, etc.

Centralized Database

A centralized database is a collection of information stored at a single location, accessible from multiple points.
Advantages:
- Fast search results due to single location searching.
- Easier to organize information in a single location.
- Easy to upgrade by adding servers to the database site.
Disadvantages:
- Can create bottlenecks if multiple users need to access it simultaneously.
- Vulnerable to data loss if not backed up or outdated backup.

Client-Server Databases

In a client/server system:
- The network database server processes all requests for data on the server itself.
- The primary advantage is reduced network traffic.
- Only the result set of the query is returned to the workstation, reducing network traffic.
