When designing an application and its tables, it’s very important to capture the time dimension and determine how data should be stored with the expectation that it will change over time. While there’s a natural tendency to keep data normalized so that the same information is stored in only one place, the time dimension also needs to be considered.

- Making Sure Data Normalization Doesn’t Lose Historical Data

Longtime client Kathy Korman Frey, George Washington University School of Business professor and GWU Entrepreneur in Residence, has engaged the FMS Professional Solutions Group to enhance her HotMommas Project website.
The site is the world's largest collection of public case studies for entrepreneurial women. It is a community where women can learn from the experiences of other women addressing their businesses, family and personal challenges.
The revamped website is built on Visual Studio .NET, SQL Server with a modern, dynamic interface incorporating our technical and graphic artist resources.

Data normalization is fundamental to database design. Properly normalized data makes it easy to support an application over time and simplifies the querying, displaying, and reporting features of an application.
Unfortunately, we don’t always receive or have normalized data. Tables that require adding fields as the data changes over time are particularly problematic and violate the basic premise of database design where adding records is free, but adding fields is expensive:
Here are some updated resources detailing the value of data normalization, including a sample database and VBA code to transpose and normalize your existing data.

Hope these help you create more scalable, maintainable, and analyzable databases.

Our long time client Kathy Korman Frey, George Washington University School of Business professor and GWU Entrepreneur in Residence, has engaged the FMS Professional Solutions Group again to update her HotMommas Project case study competition website and create another brand new website. Professor Frey has amassed the world's largest public domain collection of women's case studies, and created an environment where these women can share their experiences and challenges of creating and running companies along with juggling family and other commitments in life.
This effort is almost complete and we'll be unveiling the revamped case study competition website as well as the new "sister" site next month. Stay tuned!
