Brief History

•First conceived by Dr. Edgar F. Codd in 1969•Solves failing features of earlier database designs•Redundancy, integrity of data, over dependency on physical implementations

Concept of RDBMS

Concept

•Relation of data•Mathematical disciplines and structure•Unique language•User Friendliness•Features and functions•Most widely used model for business of all sizes

Terminology

Value-relateddata, information, null

Structure-relatedtable, field, record, view, keys, and index

Relationship-relatedrelationship, types of relationships, and types and degree of participation

•Logical &physical data independence from database applicationsassurance that changes made by the user will not adversely affect applications upon which the database is built (Hernandez, 2003).

•Guaranteed consistency and accuracy in dataData is congruent with the various levels of integrity imposed within the database (Hernandez, 2003).

•User-friendly design for viewing and manipulation of datadata can be retrieved from a particular table or from any number of related tables within the database. Enabling the user to view information in a variety of ways (Hernandez, 2003).
