  • involves converting a DB2 data extraction program in C++ to some other language -- guess what I'd like to use -- and making it run faster. (When I asked how long it takes now, they said, "Forever.") Doesn't sound difficult, so I figure there must be some complicating factor.
    Sounds suspiciously like a SQL issue, unless I've misunderstood what "data extraction" means. The fact that it's written in C++ wouldn't account for the "slowness", unless it was very poorly written.
    • Yah, the database is by far the biggest suspect: either the data model, or lack of proper indexes, or just crummy SQL, or something along those lines. But that's the low-hanging fruit, which supposedly has been picked already. So I wonder what other surprises are waiting.
