Yes, your understanding is very close. A Component for a project has Operations associated with it. A Routing (also called a Production Order) has a list of Operations that will be performed either on a Component or to make a Component. Correct, Operations take time to complete (as opposed...

Got it. Thanks. I've got the options table built and I'm filling it in right now. We have something like 80 "options." Is there something more I can tell you about our time entries that would help you understand? I could show you some very limited part of the dataset or something if it...

Hey there, Thanks very much for the response. If you were asking me to verify that any one project has only one model, enclosure type, application, customer, end user. Yes, that is correct. (One project can only have one voltage, diameter, length, number of poles, noise limit, etc. I've...

I was worried that would happen. ;-)

Thanks for the reply - I try to keep my posts relatively short & to the point out of respect for your time. I don't know where else I would get this information if not here, so I try to do whatever I can to make an answer as likely as possible. :-) Based on your suggestion, I typed this up...

I should clarify that I have used junction tables (once) in the past... but didn't have to build any forms, etc for that database because it was just a work in progress for my personal use. My understanding is that I would have one very large lookup table of all options - maybe 3 fields (ID...

So, I understand what you are both saying... but I run into an issue because going forward I won't understand how to work with the data. That is, I won't know how to build a form where a user can put in the data, and I won't know how to use the data the user put in once it's in the database...

Thank you both for the answers. Much appreciated. :-)

Hello, Currently working on a database for a "somewhat standard" product with lots of options customers can purchase. Options are almost all "yes/no" type, with a smattering of "if yes, how many" type scenarios. Database uses the product serial number as the primary key. So, is the best way...

At the risk of being too audacious, a "why" for any answers / opinions would also be awesome so we can educate ourselves. Teach a man to fish and all that... :)

Hi! A coworker and I are having a debate about the most correct way to do something. I'll attempt to describe this as objectively as possible. :-) We have a database with several lookup tables. This is for building motors, so the tables are for things like bearings, the enclosure for the...

I have a question about this statement. I understand what you mean philosophically, but not how to implement it. As an easy example... say we have a motor, and the customer has an option to buy a cooler or not buy a cooler. Once they've bought a cooler, they can choose 0, 1, or 2 liquid level...

Hi MajP, Regarding the first part of your post, that is exactly correct. The left column is a list of all the possible selections (51 of them). The blank can be filled in with a C or an E (don't know why he created it that way...). I will work on creating the table you mention in the second...

No sir... I'm essentially building it from scratch as we "speak." Right now I'm still working on cleaning up all sorts of other inconsistencies in the data set.

I agree with you regarding data storage philosophy, but no, essentially I'm dealing with a giant flat-file that someone put in Access and I'm trying to turn it into a proper relational database.

Hi there - thanks for looking at it. An example of what I was talking about using the "product line," which can be D, E, G, I, M, or T and the "Type" which has a bunch of other letters: You can have a "GA__," but not a "DA__." Similarly, you can have an "ID__," but not a "DD__." So, I'd be...

Here we go, I've uploaded it to my Google Drive.https://docs.google.com/open?id=0B-95hEnZ9g0WSVVKLV9lNWJUS3c

Awesome - thank you. I shied away from the real detail because it's a little gory and didn't want to overwhelm people. Let me think about the best way to communicate it on here... this might be a little goofy, but I'll attach the model index with the proprietary information redacted. I was...

Hello and thanks for any help. I am trying to build / fix a database of projects for a manufacturing company. Each project is for one or more parts with model numbers. Those model numbers are set up such that the acceptable characters later in the number are based on the choices earlier in...

So this is the fun part. I am on 2003, but we're a huge company and it's not standard at all. There will be 2003, 2007, and 2010.
