Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    set structure theory???

    Good morning!

    I have done a several searches on this subject and have been unable to find exactly what I am looking for. So I thought I would present it as a question and hopefully open up a discussion to get as many different theories and explanations as possible.

    The actually question is not "how" to actually point and click to set the sets up in the following scenario, but the logic and theory behind the what you link to what.

    If you have the following databases:

    cust= customer
    sku = innventory sku's
    invh= invoice header
    invd= invoice detail records
    poh = po header
    pod = po detail records

    If you wanted to created the ultimate application, what sets(as many as possible)would you create from this scenario? I know the obvious ones:

    invh - invd 1 to many
    poh - pod 1 to many
    cust - invh 1 to many

    would you :

    poh - pod - sku
    invh - invd - sku
    sku - pod - poh

    I understand linking poh to pod, would you also link that to sku? Would you also create another set for the :

    sku - pod - poh
    sku - invd - invh
    poh - pod - sku

    What does creating 2 sets:

    poh - pod - sku
    sku - pod - poh

    do for look ups etc.

    I am looking to create an application for a group of businesses and want to create a set structure that is as simple as possible, yet is as efficient and as powerful as possible. Any and all help is appreciated. As much explaination as possible, without writting an essay would be appreeciated as well.

    Thanks,

    Alan

    RE: set structure theory???

    Alan,

    The set creation is determined by the end results desired. You could set up any number of variations for sets with your tables, but having all the possible combinations would not necessarily make the application the most efficient.

    You need to determine what forms/reports you want to include in your application and that would determine the sets needed.

    Good luck
