ABSTRACT
The information engineering methodology relates well to the corporate mission. The analyst is expected to relate all the essential information system components and match those functions to corporate objectives before performing data analysis. During the information analysis stage, a data model is created. The analyst begins by analyzing the information gathered during the first stage and further defining the system objectives. The system’s data requirements are defined, the necessary entities, related attributes, and keys are identified, and the appropriate data characteristics, structure, and relationships are documented in the data dictionary. The analyst determines the operational procedures implied by data identified in the previous step. Additionally, physical file attributes are identified for the subsequent physical database design step.
