Creating an Analysis Services Cube with Visual Studio 2008 - Part 1

by Jayaram Krishnaswamy | July 2008 | .NET Microsoft

A cube in the context of Business Intelligence is a multidimensional representation of business facts that can be accessed quickly to provide specific information. (This can be accomplished by properly written queries in a relational database, but the overhead involved in processing the query, which may involve a large number of 'joins', is simply not efficient). While a relational model is more suited to OLTP, a different model is necessary for OLAP. Whereas highly normalized tables are a norm for OLTP, the model for OLAP does not require normalization. The SQL Server Analysis Services that supersedes the earlier versions is specifically meant for analyzing data in the archives or in OLTP databases to be retrieved and burnished to provide the 'Intelligence' by mining for facts hidden in the data. This two part article by Dr. Jayaram Krishnaswamy describes how a Cube is designed using Visual Studio 2008 and how it may be browsed on the Analysis Server. In Part 1, the necessary items for creating the Cube, namely the Data Source and Data Source Views are described.

Blender 3D: Interview with Allan Brito

by Allan Brito | July 2008 | Open Source Web Graphics & Video

Blender is an open source, cross platform suite of tools for 3D creation, capable of modeling, rendering, and animating 3D environments. Since Blender is completely free, everyone can download and use it immediately in commercial projects. It's not a shareware with limited tools, or time constraints; you can use it freely. In the past few years, the Blender user base has grown significantly. One of the positive aspects of Blender is its size—it is only 10 MB and we can even run it directly from a portable drive. Another great aspect of Blender is that we can use various Operating Systems such as Linux, Windows, and Mac OS X, leaving us the choice of which one to use.

Packt spokesperson Meeba Abraham approached Allan Brito at the heart of this movement to understand his take on the future of Blender.
