+ Applications may use this to determine which version of the database they are 
+ connecting to. The number is formed by converting the major, minor, and revision 
+ numbers into two digit numbers and appending them together. For example, version 
+ 7.4.2 will be returned as 70402, and version 8.1 will be returned as 80100 
+ (leading zeroes are not shown).
