Data Structure: This establishes a preliminary organization of the defined data elements into logical records and the relationships between these logical records. The data are organized in a way that facilitates the processing of inputs to generate outputs and satisfy other computational requirements. Generally, this is best accomplished by defining data structure that models the way in which data naturally occurs in the environment. As a part of this task, the project team organizes required data elements into logical records or schemas and develops an initial specification for these data element groups and group relationship. A data structure chart is then prepared to illustrate the logical relationships among the records defined above. Connecting lines may be used to indicate that one record can be logically accessed from another. In addition, a key is identified for each record that may be directly accessed. The objective of this task is to define a logical set of records and record relationships that satisfy the user-based requirements of the new system.
