Answer to Question 1

Sequential, indexed, and hashed are the three file organizations presented in the textbook. When using the sequential file organization, the rows in the file are stored in sequence according to a primary key value. When using the indexed file organization, the rows are stored either sequentially or nonsequentially, and an index is created that allows software to locate individual rows. The hashed file organization method uses an algorithm to determine the address for each row.
