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.

Multi Company within same database

  • Multi Company within same database

    We are a landscape company that has developed our own custom database since the DataStar using CP/M days up to Microsoft Access 2003. We started asking ourselves why we couldn't "commercialize" what we have done so other small landscape companies wouldn't have to reinvent the wheel and use our system. After many days of research we have settled on what appears to be a great solution with Alpha Five.

    Therefore, we have all of the typical newbie questions of going from Access to MySQL/AlphaFive along with the bigger overall design of the database. I am currently paralyzed as to the direction I should go in by converting our current single company designed database into a multi-company database.

    If there is one thing we have learned over the last 25 years that the database will be evolutionary and not revolutionary. Meaning, there will be constant changes/improvements to the code/design of the database. Thus, I would like to stay with a single database design so that I do not have to track and maintain individual databases for each company.

    Therefore, basically all of my tables in the database will have to have columns and keys added with a company id in order to filter out data from other companies. The problem is how to manage the users and companies logging into the database. Examples being Company A may only need 2 simultaneous users while Company B needs 7 simultaneous users and then isolating them to manipulate only there data from all of the communal tables. I envision our commercial model will be company's paying a monthly fee based on how many simultaneous users they need.

    I have looked at the web security framework and AlphaToGo's frameworks and understand them to be basically designed for single company designs. I need that type of framework, but another layer added above that for a company level.

    Hope this makes sense. Unforunately, I have never had a formal database or for that matter computer class and have learned everything I know from reading, time, and a lot of mistakes. I have also learned that the first steps are the most crucial as to laying the foundation for the rest of the database.

    Thoughts, directions, and theories would be greatly appreciated.

    I think you are on the right track. If it were me, I would start by building a user management grid tied back to security. Your user grid would include company name/id as well as user id. When the user logs in, you retrieve the company id as well as the user id and set them to session variables. All tables will need a company_id field as you suggest and you then filter the tables on the company session variable.

      Thanks for the input. Since I have never come up with an original idea in my life, do you know of any examples I could look at of a user management grid being tied back to security that you spoke of?

        If you send me an email, maybe I could send you a sample component to study.
