'''Abstract of no more than 500 words:'''
I am sure we have all been in the situation of having mountains of data stored in our database, needing a piece of information and yet being unable to determine how to get what we need. Computerized databases have been around for decades now and there are several architectures available; however, the ability of a database developer, regardless of the architecture, to store data in a format that is comprehensible to a businessperson yet readily accessible through software applications remains an impossible challenge.
Topics to be discussed include
o Components comprising a logical model, how it is developed and how is it used
o Components comprising a physical model, how it is developed and how is it used
o What does a logical model look like
o What does a physical model look like
o Who works with a logical model and why
o Who works with a physical model and why
o What is the relationship between the logical model and the physical model
o What kind of a time investment is required to develop and maintain logical and physical models
o What are the challenges of keeping the two models in sync as the software application evolves
Although data modeling is a huge discipline and presents research topics for millions of theses and dissertations, this twenty-minute snapshot view will allow anyone, technical or business, to sit through a development meeting and be able to grasp what is being discussed as well as gain a better understanding of logical and physical business flows.
