- I'm in no position to confirm the rumour about the .INP files, but last week
- some Oracle reps came out to our organization to give a technical overview
- of Oracle7, and a glimpse of future product directions. Part of the
- discussion centered around SQL*Forms 4.0, and according to the reps, Oracle
- is "considering" the elimination of the .INP files in 4.0. Apparently the
- matter has not been finalized yet, and it was suggested that our concerns be
- aired in order to help Oracle make their "decision".
-
- Issue #1 - Change control - Tools like RCS and SCCS (UNIX) or CMS (VMS) are
- essential in a multi-person development environment to prevent
- simultaneous (accidental) modifications. Developers "check out"
- the .INP file to ensure exclusive access to the form definition
- during the development cycle.
- Issue #2 - Version control - Every once in a while, Murphy strikes and
- something goes drastically wrong. It becomes necessary to go
- back to a previous generation of a form and reengineer
- the changes. With SCCS or CMS, these earlier generations of
- .INP files can be reconstructed and reserved.
- Issue #3 - It is also valuable to be able to determine what changed between
- generations (and not necessarily adjacent generations). To do
- this requires "differenceable" code (aka, ordered text files).
- (Note that .REX files from SQL*ReportWriter are hardly
- "differenceable".)
- Issue #4 - Many development shops are willing to circumvent "supported"
- actions if the result is going to be cost effective (faster),
- as long as safety/reliability is not significantly impacted.
- The direct editing of .INP files, although not supported by
- Oracle, is relatively safe (especially with a code management
- system where the original version can be refetched) and is
- a proven time-saver (global edits, search/replace operations).
- The cost to apply the same change (such as boilerplate text) to
- many forms can be enormous compared to using a stream editor like
- SED on .INP files.
-
- IMNSHO, until Oracle can provide change control, version control, the ability
- to identify differences between different forms or generations of the same
- form, AND global search/edit capabilities, there will be a STRONG DEMAND for
- .INP files (or their equivalent) by most development shops doing serious
- development work.
