A relational database is the primary method for organizing and maintaining data today in information systems. It organizes data in two (2) dimensional tables with rows and columns called “relations.” Each table contains data about an entity and its attributes. Each row represents a record, and each column represents an attribute or field. Each table also contains a key field to uniquely identify each record for retrieval or manipulation. Provide examples of five (5) good key fields.
