Once the conceptual design is finalized, it's time to convert this to the logical and physical design. Usually, the DBMS is chosen at this stage, depending on the requirements and complexity of the data structures.

The design phase is where the requirements identified in the previous phase are used as the basis to develop the new system. Another way of putting it is that the business understanding of the data structures is converted to a technical understanding. Tutorial 2 – The Database Design Life Cycle Answers to Review Questions 1. What is an information system? What is its purpose? An information system is a system that • provides the conditions for data collection, storage, and retrieval • facilitates the transformation of data into information • provides management of both data and information.

Overview. Once the conceptual design is finalized, it's time to convert this to the logical and physical design. Usually, the DBMS is chosen at this stage, depending on the requirements and complexity of the data structures. Ideally, this phase of the database design process should be performed by a team of database professionals, subject-matter experts, and end users. Even with a very high level of diversified
