The Perron Electronics Assembly Company (PEAC) needs a database to track its training program. PEAC has several trainers and they offer various courses for their employees. Courses are offered numerous times throughout the year. Each course offering is taught by just one trainer and every trainer is capable of teaching all of the courses offered through PEAC. Design a set of tables and relationships for PEAC in 3NF. Represent your answer in DBDL (i.e. give table name & fields. Underline primary key.) Draw an Entity-Relationship Diagram using Visio or Lucid Charts.
