Do you know there are hundreds of additional tasks, tools, and components for SSIS, many which are free? Why re-invent the wheel? Take a look at this exhaustive list created by Todd McDermid on CodePlex: SSIS Community Tasks and Components. It is split into the following categories:
SQL Server Master Data Services (MDS) has a number of enhancements in SQL Server 2012:

If those fields needs to be tracked in a fact table, the result could be many small… Read more
A factless fact table is a fact table that does not have any measures. It is essentially an intersection of dimensions (it contains nothing but dimensional keys).

If you are using Visio 2010 and creating tables via the Database Model Diagram template, you may be surprised to learn there is not a way to build CREATE TABLE scripts from your resulting diagram.
