Hi

1. gotcha - australian colloquial (i guess) - the little things that go 
wrong that you just don't expect - they "get you"
2. team size - me
3. yes 30 years - i'm known for me bloody minded persistence - 
translation from australian - persistence in the face of potential 
failure /impossible difficulties, until the job is done
4. SQL (from memory) was originally defined by Ted Codd as part of 
System R - the first relational database. It was later formalised and 
then standardised. The standard has been updated over the years. You can 
implement SQL by implementing a language that conforms to the standard. 
You can extend SQL informally by adding to a conformant product and by 
offering the extension to the body that maintains the standard. That's a 
reasonable process used all the time by the mainstream database vendors. 
Of course you can call anything you like SQL, but if it doesn't have a 
conforming base you'll just annoy all your potential customers - they 
will object to the deception.
5. one to one translations - ultimately to machine code - is an 
important subject, but not enough space to cover that here.
