Tips for Running the Dynamic Data System (DDS)

The Dynamic Data System (DDS) makes loading a data warehouse much easier and faster. This system uses SSIS to load standard and partitioned tables via SSIS packages created on the fly using metadata. This eliminates the need to maintain complex SSIS packages. Only basic T-SQL skills are needed. The Dynamic Data System is available on CodePlex.

My current data warehouse project uses SQL Server 2008 R2. Out of the box I found a couple minor configuration issues that prevented me from getting started with using DDS. The following notes, in addition to the documentation provided with the product, should get you on your way.

ASP.NET MVC – LabelFor htmlAttributes Extension

Android Critters Retired

The Android version of Critters has been retired so we can focus our resources on our next version. Trying to keep the application viable on three different versions of Android (2.x, 3.x, and 4.x) for no cost and creating a new version was consuming more resources than were available.

For those currently using the Android version, you may certainly continue to use it; however, we will not be releasing any future updates and the application has been removed from the Android Market. If you need to re-install the old application, please contact us and we will e-mail you an APK of the last release. You can install the APK directly from e-mail, if you have set your security to install applications from “Unknown sources”.

The next generation of Critters will be web based and work on a variety of traditional and mobile platforms. By focusing on the web, we hope to make updates and fixes more timely and transparent. See our page on facebook so we can get your thoughts and ideas of what we need to make Critters the best personal veterinary record ever!

Thank you for using Critters!
