Relational database terms and concepts are taught in a simple     and practical way. Our technique can be used to develop applications for     e-commerce, servers, or personal computers. ERA is designed to improve     productivity and communication between users and analysts, yet is equally     effective when used by people developing systems on their own. The method is     structured so that every activity results in a tangible product that directly     contributes to the final system./p>  p classh2>Audience/p>  p>Our ERA course is available in workshop and overview format.     The workshop is designed for developers of relational database applications.     The overview is directed at end users and anyone interested in a brief     introduction to relational database design concepts and terminology.     Both courses will also benefit individuals who are evaluating alternative     technologies and design proposals for data-oriented systems./p>  p classh2>Outline/p>  p>The ERA Process is taught, step by step, as it is used in the development of     an application. It begins by identifying the persons, places, and things     (entities) of the users business, and modeling them in table form. Next,     relationships between entities are identified and documented in the same     concise and unambiguous way. Finally, attributes of both entities and     relationships are identified and normalized into the proper table. Sample data is     always used to verify the model. The result is a data model that is precise,     complete, flexible and yet easily understood./p>  p>img srcimages/eracircle.gif border0 width497 height253 altera circle>  p>The methodology also addresses the following advanced topics: face-to-face     interviewing techniques; entity types and sub-types; parent and dependent     entities; intelligent keys; and advanced forms of one-to-one, one-to-many,     and many-to-many relationships including recursive relationships, complex     relationships, and time relationships./p>  p classh2>Objectives/p>  p>The successful ERA Workshop student will be able to:/p>  p>• Understand relational database terms and concepts    br>• Develop a relational model for a business situation    br>• Participate in database design sessions    br>• Establish clear and concise communication between user and analyst    br>• Propose, evaluate, and choose between design alternatives    br>• Understand the capabilities and limitations of a database design    br>• Determine the relative quality of commercially-available RDBMS products  /p>  p classh2>Availability/p>  p>The ERA Workshop is usually taught as a three-day class, and the ERA Overview as     a half-day class. The Workshop materials include a 170 page manual with detailed     exercises and answers, a table drawing pad, three colored pens corresponding to     each modeling step, and a handy reference card.

Students are taught how to solve difficult     problems by developing solutions a piece at a time. The same approach is     used to teach database maintenance and definition. Our class teaches a generic     SQL that can be used with a variety of relational database products./p>  p classh2>Audience/p>  p>Computer users and developers who need to use SQL, but dont want to spend     a month learning it. No previous programming experience is required. Exercises     are included for both the beginner and advanced student./p>  p classh2>Outline/p>  p>First day topics center around single-table queries:     selecting columns; ordering columns; formulating basic comparisons;     selecting rows; sorting rows; eliminating duplicate rows; specifying     advanced comparisons; using arithmetic expressions; applying statistical     functions; and creating column aliases./p>  p>On the second day, multi-table queries are studied, including joins,     unions, and subqueries. How to insert, update, and delete data is covered     next. Finally, students create tables, indices, and views, with appropriate     integrity constraints./p>  p>The class is comprehensive, yet practical.

This data must be loaded into a relational     database (not provided) to perform the exercises in an interactive mode.
