Ever-larger electronic text archives have the advantage of allowing a more complete analysis but the disadvantage of forcing longer waits for results. This thesis addresses the issue of efficiently storing data in a literary data warehouse. The method in which the data is stored directly influences the ability to extract useful, analytical results from the data warehouse in a timely fashion. A variety of storage methods including mapped files, trees, hashing, and databases are evaluated to determine the most efficient method of storing cubes in the data warehouse. Each storage method's ability to insert and retrieve data points as well as slice, dice, and roll-up a cube is evaluated. The amount of disk space required to store the cubes is also considered. Five test cubes of various sizes are used to determine which method being evaluated is most efficient. The results lead to various storage methods being efficient, depending on properties of the cube and the requirements of the user.
