Access & SQL Server
I realise that this posting will be a little bit off-the-point, but here goes.
Access vs SQL Server...
Comparing these two is a bit like comparing Access and Visual Basic.
In both cases Access will deliver a level of functionality that will work
in a simple and cost effective manner. But if you want to bet your business
on the solution you need to pay more (both in time and license fees).
If you want a simple solution to a desktop application for small numbers
of users then Access's default bound-forms are great. They are far more intuitive
than VB. Similarly with Access and SQL Server - I'm sure that many newcomers
to SQL Server have struggled with MDF's and wondered why you can't simply
copy and paste them like MDB's.
if you want to build an application with 10 lumps of functionality it may
take 10 hours in total (1 hour each). But if you want 100 lumps of functionality
this is likely to be a lot more than 1 hour each.
More "Serious" tools (SQL Server / VB) take more work but "Easier" tools
are more limited. Access CAN'T be an alternative to SQL Server for every
application - if it was then Microsoft wouldn't sell it.
If you want to scale an application then you need serious technology - you
need ADO / Stored Procedure / n-tier / data-layer / COM+ - and you need all
these even if you are changing on value in one record. So 2-3 lines in Access
equates to maybe 100 lines if you add all these different technologies together
One last thought - Don't let anyone from the Access bb read any of these
last few days postings - they'll never believe that we write all those 100
lines of code..
