A logical design is a conceptual, abstract design. You do not deal with the physical implementation details yet; you deal only with defining the types of information that you need. The process of logical design involves arranging data into a series of logical relationships called entities and attributes. An entity represents a chunk of information. In relational databases, an entity often maps to a table. An attribute is a component of an entity and helps define the uniqueness of the entity.
Deciding how and where this information is stored is the domain of the database designer. Working with a system architect and a requirements analyst, the database designer ensures that all necessary data has a place to be stored. At the same time, the speed at which the data can be stored and retrieved are taken in to account so that user's are not left waiting for unreasonable amounts of time. Sometimes database designers take on database related activities such as arranging for backups, creating ad-hoc reports, and server tuning. However, these other tasks are often part of a Database Administrator's (DBA) job. Related Terms. 1  Database Administrator (DBA). 2  Data Architect. 3  Data Modeler.
