In fact, the basic purpose of building a logical database design is to ensure that all the entities and their possible relationships required by the database are entirely and exactly identified and described. In view of the fact that logical database design is built using easy to understand symbol and language, hence it can be easily examined and validated as accurate by the end-users. As discussed above, this logical database design works as a guide that is to be followed by the database developers to use as a “blueprint” for developing the physical database model. In this scenario, the information provided in the logical database model is utilized to describe the relational tables, entities, stored procedures, primary and foreign keys, and triggers (Liberty University, 2013).
