1.4.1 Using EADS as a write buffer

You can use EADS as a write buffer in application systems. A write buffer is memory for storing data temporarily to eliminate disk access overhead during data write operations.

The figure below shows an example of an update application program that uses EADS as a write buffer. This example might be for a system that handles a large volume and wide variety of data, such as a reservations management system or an online trading system.

Figure 1‒2: Using EADS as a write buffer

1. A client accesses EADS to update data such as reservation information.

2. EADS temporarily stores the data to be manipulated by the client (using EADS as a write buffer).

3. EADS writes the updated data in the RDBMS.

You can eliminate disk access overhead and achieve high-speed data processing by using EADS as a write buffer, without writing data directly in the database.
