CONCEPTUAL DATA MODELING: THE ENTITY / RELATIONSHIP MODEL

By far our most popular skill-building seminar, Conceptual Data Modeling (CDM) is an intensive course in the discipline of Conceptual Data Modeling (entity/relationship level of data modeling). It is one of the most powerful and effective analytical techniques ever developed for understanding and properly organizing the information required to support any enterprise.

This form of modeling can be applied on a very large scope (including the entire enterprise) or any smaller subset down to modeling the data required for a single application in the enterprise. CDM generally gives greatest benefit when used to model, integrate, and eliminate redundancy across the entire enterprise, helping to ensure the same data will never be stored twice. Applied on an enterprise-wide basis, CDM focuses on the big picture, and surfaces everything the business must know and keep data about in order to operate effectively. Data subjects (entities) are shared across functional, process, and organizational boundaries within the business, and so this model (and the shared databases which will ultimately be physically implemented from it) are the keys to removing unnecessary time and cost in the conduct of business processes - the complete collapse of "information float". It is truly analogous to everyone in the enterprise being able to know the same thing at the same time. CDM is also useful in conceptualizing data to be shared directly with customers and suppliers (usually via the internet today) to further collapse time and cost. Building a CDM invariably surfaces conflicts and ambiguities in business terminology, business rules, and practices which inevitably cause quality problems for the customer of the enterprise, legal risks, and errors and inconsistencies which are costly and troublesome to correct. Building a CDM gives the enterprise a golden opportunity to "clear up a few things around here" in a very organized and methodical manner. Extensive workshops in the CDM seminar fully develop modeling skills. The seminar material is completely independent of any vendor's CASE tool or DBMS.

This is by far the most complete and advanced CDM seminar available anywhere, and gives the student a complete set of tools, rules, skills and constructs to properly model any complex requirement they will encounter in a real-life modeling effort. Our instructors teach in plain, jargon-free English, so no previous data modeling knowledge or experience is required.
