RE: To cast or not to cast?

UInt32: Int will do. Signed and Unsigned integers are actually the same;
just cast them to the right type.
UInt16: SmallInt, see warning above
Byte: TinyInt
BioAPI_*: look up underlying type definition and use it. Enums are Int32 by
default.
IntPtr: it's Int32, so store it as Int.

Note, however, it's probably pointless to store pointers in the data base.
Pointer itself is not important, most likely you need to store whatever
it's pointing to.
