Pre-Built Data Marts / DW

[antexity]

Hello All,

I was entertaining the idea of Pre-Built solutions and came across a company called Rapid Decision. Has anyone heard of them, or have implemented Pre-Built solutions such as Data marts/WH etc?

What are your thoughts of pre-built solutions?  What are the disadvantages?
Do you know of any other companies that provide the same type of solutions?

According to Pre-Built solutions, you save a lot of time and money but why are a lot of companies doing the original method?

Hoping to hear a few comments,

Thanks so much,
Jonathan
