- Steve,
-
- To my understanding, DAL requires that you purchase and install a DAL server
- on your host. According to sources that I have tapped into at Oracle
- and at the IOUG conference in S.F., DAL is actually a poor performer because
- it has to go through an additional layer after SQL*NET. In other words,
- you would have Excel->DAL->Dal(Host)->SQL*NET->oracle........or something like
- that. The SQL*NET layer is actually a bunch of lower layers piled up.
-
- Anyhow, I would look into some other products if I were you. There are 2
- other ways to get data from Oracle into Excel on the Mac. We have not tested
- either of them yet, but I have already ordered the later of the two for testing.
- They are called 'Second Wind' and 'Clear Access'. Clear Access looks to be
- far superior to Second Wind. Clear Access comes with a DA that will let you
- suck oracle data into ANY macintosh application via the clipboard. It also
- provides 12 functions that are callable from an Excel Macro. (It actually
- provides these programming hooks for many different macintosh applications
- that support some sort of scripting or macro language). If you are familiar
- with Excel macros at all, then you will know that it is possible to create
- Excel Add-in's that are basically macros. Items can be installed into the menu
- bar and so forth. Clear Access itself has its own scripting language, and
- provides a GREAT DEAL of flexibility. I was very impressed by this product
- at the IOUG conference. 95% of the mac-based demonstrators there were using
- Clear Access to bring data from Oracle into their application. Its
- performance is very superior to DAL because it uses SQL*NET directly, without
- the need for the DAL server software on the host, although it does require
- SQL*NET on each mac. They are also working on some new software that will
- include a full fledged Oracle ReportWriter(GUI). One last thing, they have
- both Mac AND Windows versions and they look and feel and program and configure
- the same!!!!
-
- If I were you I would at least check it out. They have
- a fully functional demo version(it doesn't go to oracle, but rather to a local
- mac database that they provide) that will show you what you can do and let
- you play with it. Give them a call (515) 472-7077. Let me know how it comes
- out as we are also trying to evaluate mac based client packages.
-
- We are attempting to make the slow transition to client/server.
- Have you had any experiences with other Mac-based software that taps into
- Oracle?
-
- Good luck!
-
- PS -
-
- Second Wind just gives you access to Oracle through Excel. It is much less
- flexible than Clear Access. It is also a smaller opertation. I got the
- sense that it was a couple of guys working out of their home. However, it
- was still reccomended over DAL because it goes straight through SQL*NET
- like Clear Access does.
