Data Model Patterns: A Metadata Map by David C. Hay

By David C. Hay

Lately, businesses and govt organisations have come to gain that the knowledge they use symbolize an important company source, whose price demands administration every piece as rigorous because the administration of human assets, funds, and capital apparatus. With this attention has come attractiveness of the significance to combine the information that has normally simply been on hand from disparate assets. an enormous portion of this integration is the administration of the "metadata" that describe, catalogue, and supply entry to many of the different types of underlying company information. The "metadata repository" is key retaining music either one of a few of the actual parts of those platforms, but additionally their semantics. What will we suggest by way of "customer?" the place do we locate information regarding our buyers? After years of creating firm types for the oil, pharmaceutical, banking, and different industries, Dave Hay has the following not just constructed a conceptual version of the sort of metadata repository, he has actually created a real company information version of the knowledge expertise itself. * A accomplished paintings in accordance with the Zachman Framework for info architecture-encompassing the enterprise Owner's, Architect's, and Designer's perspectives, for all columns (data, actions, destinations, humans, timing, and motivation) * presents a step by step description of version and is prepared in order that various readers can make the most of diversified components * presents a view of the area being addressed by way of the entire options, tools and instruments of the knowledge processing (for instance, object-oriented layout, CASE, enterprise technique re-engineering, etc.) * provides many suggestions that aren't at the moment being addressed via such instruments - and may be

This is still without reference to any particular technology. For example, business owners’ views of business rules encompass all constraints that might be imposed on a business, whereas the Architect’s View is only of constraints that affect the updating of data or the processes of doing such updating. ∗ The architect’s perspective eliminates all of these. Mr. Zachman originally called this the “Information Designer’s View” because of its role in making the structures suitable for automation. The word designer, however, has the connotation of applying technology to the solution of a problem, even though this row really simply represents the final stage in describing the enterprise as rigorously as possible.

Each half of the association (going in one direction) is a role. “Role” is then another object class in our metamodel, as shown in Figure 1–5. One attribute of Role is “Cardinality”, which is the maximum number of occurrences of an associated class that may be related to an occurrence of the class playing the role. Another attribute is “Optionality”, a binary variable determining whether or not an occurrence of the role must be present in the first place. Each role, of course, must have a “Name”.
