  The main workhorse behind everything that was done at Shoestring Commerce was based on being able to store, serve, and search large amounts of data. The project required having many different databases, such as ones for storing the product catalogs, databases that stored orders, and finally client databases that were stored on separate servers, sometimes in other packages. It was important to maintain data concurrency amongst all the different databases so an item was always uniquely identified.

  I would like to remind you that the whole 35psi venting is not mentioned anywhere when I did the review, it was only after my review that we found out how it was supposed to vent!!
  I asked the maker twice after my review to give me detailed info so I could pass it on but both times was threatened with legal action!
