Data Structure Analysis

Before defining the object structure, you analyzed the structure of the legacy data to help you define the object structure and the attributes of each field. You can use this data analysis to determine the amount of data that will be stored in the database, which will help you size the master index database and decide how to best distribute the database. Knowing the volume of existing data plus the expected daily transaction volume will help you plan the requirements of the database server, such as networking needs, disk space, memory, swap space, and so on.

The data structure analysis also helps you determine the processing codes and descriptions to enter in the common tables (described below), and should help you determine any default values that have been entered into certain fields that could skew the matching probability weights.
