Table Variables

Reel and frame give the location on the microfilm files where the particular transaction is recorded. The reel number and frame number are unique to a transaction between the assignee and assignor. The recdate is the date the assignment was recorded. The actionkeycode is an indicator for whether the transaction was included in a daily, weekly, bi-monthly or annual release.[1] The trandate is when the data was extracted into the file. The table has a composite key consisting of reel, frame, and recdate.
