- I've never worked directly with PICK, but I develop in an environment that
- was derived from PICK.
-
- PICK's main attributes are that it is based on variable length records with
- the possibility of multi-variables within single fields of a record. Each
- record is essentially a string with different kinds of delimiters to determine
- the end of a field, multi-value within a field, or even sub-value withing
- a multi-value and so on. The allows for easy database restructuring and
- design, but suffers some in the speed department when compared directly to
- fixed field/record length database environments.
-
- PICK was originally designed as the operating system so that the speed was
- regained as actions were OS and not on top of the OS. I don't know how the
- UNIX based PICK is set up exactly.
-
- Things that it would be very good for is if you have lots of text fields in
- you database, or even pictures or any data that might need to be long, but you
- don't want to have to declare a maximum length of the field.
-
-
- Remember, since I've never worked directly with PICK, some of what I just
- said might not be exactly right, but hopefully will give you a general
- idea of what it's about.
