Queries VS VBA Design
My partner and I developed an access database using queries instead of VBA
because we will not be the ones who will edit and update it and the people who will do not write VBA but do work extensively with queries. We have now been told through other people that an experienced designer stated our system will NOT work, will overload the system and will cause the linked table to corrupt and disrupt all of the other programs (which are VBA code based) because of the database being query based. The databasehas been converted to mde. Is there any problem running the database with approximately 6,000 records and maybe 100 users working on it at one time with a query based database and the shared records also being accessed by VBA written database? |

I manage a one million record database set up just that way. The tables are
all on a sql server and then users have an Access front end on their machines. They log into the server and use the data they need through queries, forms and reports. I probably have somewhere around 50-60 queries that are used to power different forms and reports that various users use. The tables are backed up each day and the users are responsible for backing up their forms or reports that they use. We have no problem at all with that system, provided the server soesn't go down, which is very infrequent.

Would there be a problem using a query based front end database with 2 VBA
based front end databases? They all use the same backend database. "Golfinray" wrote: I manage a one million record database set up just that way.

No. You would need separate icons for users to go into the 3 different
databases unless you somehow wanted to link them all together, which is possible. I would recommend just staying with the 3 separate for ease of use on your part. Just go to the desktop of each user and put a shortcut to that database or however you want to set it up. Just be sure they have access to all the tables they need, most likely on a lan, and you should be good to go.

I'm sorry I was not clear with my description. All of my users do share the
databases across the LAN and have their own icons on their desktops. -- I was told by an access guru that 2 VBA written access databases and 1 query designed access database cannot share the same backend files without a lot of errors and degradation. I do not know of this as a problem but would like to know if anyone else has seen this problem.

Multiple front ends hitting a shared back end can possibly step on each other with respect to record locking depending on what they are doing, but it has nothing to do with mixing front ends that access the data from code versus from queries. -- Rick Brandt, Microsoft Access MVP Email (as appropriate) to...

I develeoped a system here where there are 73 backends and 30 front ends. I use both VBA and Queries. It has been running extreamly well for 9 years now. Its all in the design. If you want some tip/tricks just email "Rick Brandt" wrote: AccessNewbie wrote: I'm sorry I was not clear with my description.

I can't understand why there could ever be any justification whatseover for multiple back ends to any front end -- it sounds like the data has been split up incorrectly to me. I hear that SQL is eayier. For what? What do you use to develop the front end? -- David W. Fenton http://www.dfenton.com/ usenet at dfenton dot com http://www.dfenton.com/DFA/ |
