Information and Data Modelling for the Enterprise

One of the most important tasks in the development of enterprise-strength software applications covers the analysis and design of the information and data structures that will be needed to support the achievement of the business goals. These structures must be validated against the relevant business and software processes, so that the resulting information system is seen as fit for purpose, and contributes effectively to the realisation of corporate strategy.

Information, and the data that supports it, are among the key strategic assets available to the enterprise as it pursues success in the execution its mission. Hence, Information and Data Modelling forms an important part of a wider enterprise function, Information and Data Management. Ideally modelling would be conducted from an enterprise perspective, thus avoiding the creation of isolated project or functional databases, which must then be integrated at great expense to complete the corporate view needed by senior decision makers.

This course situates Information and Data Modelling within the Management function, and exposes the main techniques useful to the modeller in deriving the required Information and Data structures in accordance with recognised best practice. The course makes extensive use of the UML notation, where applicable.

Learning Objectives

  •   Justify the need for modelling within the Information and Data Management functions
  •   Develop a Conceptual Data Model
  •   Develop a Logical Data Model
  •   Apply a range of techniques to validate data models against business requirements
  •   Apply the normalisation technique as a way of analysing and designing attributes, and as a way of validating data models
  •   Rationalise and integrate the bottom-up view of data with the top-down view of information
  •   Approach the design of schemas for physical databases
  •   Approach the design of schemas for BI applications based on OLAP databases
  •   Articulate the need for a corporate view of information and data, and be aware of the issues involved
  •   Understand some approaches to performing quality checks on the models produced
