Completing thesteps out of order may complicate the project or result in an incorrect result.1. Begin by creating a new Microsoft Access database namedlastname_firstname_ntrp.accdb .2. We would like to begin by making a table to store the television networks.a. Create a table named Networks to store the names of the televisionnetworks and their abbreviations. Designate the abbreviation as primarykey.b.

Please proceed to the next step.5. To finish adding our dataset, we must store information about the shows.a. Create a table named Shows to store information on each of our shows(listed below under Step 5b). Some requirements for this table appearbelow.IMPORTANT: Completely define the Shows table before entering records.i. For the primary key, use an AutoNumber-type field to store an IDnumber.ii.Create a text field to store the abbreviation for the show’s network(e.g., “FOX” for the show Family Guy).iii.iv.For the network abbreviation, create a relationship to the primarykey of the Networks table to indicate which network airs each show.Enforce referential integrity and enable cascade updates, but do notenable cascade deletes.Provide a field to store the name of the television show.Using a lookup field to the Genres table, allow the user to specifythe show genre. The user should be able to select the full name ofthe genre (e.g., “Drama”) from the lookup field dropdown list.Enable data integrity, restricting deletes, on the relationship createdby the Lookup Wizard.v. Provide a fixed-type number field with 1 decimal place to store theshow’s rating.vi.vii.Provide a field formatted as a percentage with 1 decimal place tostore the show’s viewer share.Include a standard-type number field with no decimal places tostore the number of viewers.Introduction to Computer ApplicationsWest Virginia UniversityPage 2 of 6 Version 14.9Modified 2/20/2015
