Hi..I am arun and Thanks to all of you in advance for solving my
problem...
I am working as a quality co-op for Maytag and I have developed a
defect tracking database using access and VBA. It looks good and its
performance is good.
My problem is in data accessing and the size of the tables.
1. More than 15 people are going to access the database.
2. There are 5 lines and there are 3 stations in each line entering
data.
3. There are 3 Quality engineers, 5 manufacturing Engg, 3 lean sigma
guys and 3 directors (not mentioning the team leaders, supervisors and
co-ops) accessing the queries.
4. I have one main table for data entry and 2 more small tables for
other stuff. From these 3 tables, I take data for my queries.
5. 15 people access the main table for data entry simultaneously (5
lines, 3 stations each line).
6. So, I decided to have 15 differant database with same underlying
structure. Then each and every one of the engineers,team leaders,
supervisors and Directors having their own FE and accessing the tables
by the LINKED TABLES concept. IAM YET TO DO THIS STEP.
7. My question is whether this is the right method to do it?
8. Every production line has 150 enteries a day...so we are talking
about 540k records for an year....
9. Please advice me on my data base design...Mainly on my table
design. whether i should have 15 different tables of the same dsign
and then link them to the FE or create temp MDB etc
Please start with some general comments and advices and I will explore
those comments and will go deeper...

I'd put these in one table.

Not too much of a problem.

You should really, really have one MDB with a FE for each workstation.
If you find you are getting a lot of locking issues with everyone entering new
records then you might want to consider using a temp tables for the duration of the
data entry and then append those records to the main table at periodic intervals.
However you really won't know this until the folks start using the system in volume.

I have ODBC linked tables to a SQL 7 database in an A2K database. The linked
tables do not have the password stored in them, so the first time the user
accesses them, they need to enter the SQL password.
I am developing a process that will automatically run at night which will
access those tables. I need to be able to give Access the password, as the
user currently does, so that the process can run without a password prompt

the data contained in the linked tables. For tables that involve a number
field as the primary key, the data is returned successfully. For tables
that involve a character field (e.g. CHAR(3) or VARCHAR(10)) as the primary
key, I have the correct number of rows returned, but the data displayed...

Hello there.
I have a question somewhat related to this topic, and I don't know
where else to go. I hope somebody can help. I've created a database
in access, that I'd like to share with less than 10 users. I'd like
each user to see only some of the records in the database. So for
example, if I have eight users in eight countries, I want each of them
to only see information for their country.

The code below works great IF the previous back-end database connection is

However, if you remove or even rename the old database, then launch your
