Step 1: Understanding the Concept:
A Database Management System (DBMS) is designed to store, retrieve, and manage data efficiently, maintaining accuracy and accessibility.
Step 2: Detailed Explanation:
Let us evaluate the listed characteristics of a database system:
- Minimum cost (A): Ensuring high performance at a lower cost of storage and administration is a desirable goal.
- Search capability (C): A database must allow users to query and retrieve data quickly and easily using search indexes. This is essential.
- Data integrity (D): Maintaining data accuracy, consistency, and reliability through constraints and validation rules is critical. This is a primary goal of a database.
- Redundancy: This refers to the duplication of the same data in multiple places.
High redundancy is undesirable because it wastes storage space and can lead to data inconsistency (where the data is updated in one place but remains outdated in another).
One of the main purposes of a database system is to minimize or eliminate redundancy through normalization.
Therefore, "Maximum redundancy" is not a desirable characteristic.
Step 3: Final Answer:
Maximum redundancy is not a desirable characteristic of a database system.
