Reverse Auction Defined. You probably think you have a good understanding of how most auctions are done. For example, you may have bid on a product you found on eBay. If another person wants the same item you want, she may bid higher than you to get it. Of course, if you still want the item bad enough, you may bid higher yet.
Custom Data Types: Ability to Create them in Setup. I would like to create my own data type in SalesForce. When we create a New Field, we have to choose from the built in options for example, Date, AutoNum, Checkbox, Picklists, text, lookup, etc.
A Variant is a special data type that can contain any kind of data except fixed-length String data. (Variant types now support user-defined types .) A Variant can also contain the special values Empty, Error, Nothing, and Null. You can determine how the data in a Variant is treated using the VarType function or TypeName function.
