(2004)Essential Strategies, Inc. was also retained to help two different New York banks to select a commercial data model. This was done by first preparing a "sketch" conceptual model, in order to learn the essential components of each client's concerns. This model was then used as a template to evaluate a set of three vendor models plus (in one case) several models developed by the bank itself. Both the vendor models and the in-house models were "logical" models, in that they each reflected a particular relational database design. The conceptual model was useful to determine what concepts these models did and did not have.
(2009)During his tenure as Manager, Information Strategy and Architecture with Capgemini Financial Services, David Hay worked for an international United Kingdom bank to prepare a strategy for data governance and information architecture. The objectives of this project were to provide a view of information across the bank, establish an enterprise-wide information governance culture, and to create an enterprise information model framework to establish the basis for managing informatin and services across the bank. While he supported all of these objectives, in particular, he developed an enterprise semantic model to provide the foundation for all of them.
