I am dealing with a new type of schema that was recommended to me because of the possibilities of many to many relationships between each table of information.
To give a summary - We have projects. Each project will have assets or media that we received. Each asset can be a different asset type, such as hard drives, CDs, DVDs etc.
Each asset gets a unique asset tag comprised of the project id (intematter) a sequential counter with a 00001 padding, and the asset type. so an example would be 123456_00001_HDD.
We process each asset into a tool call Nuix. We may create multiple nuix cases in a case, and each asset may be processed into multiple pieces. This allows us to split 1 hard drive into multiple sets of evidence, based on assigning portions of a drive to different people or departments.
Sorry for the long description, but I have read that the better the explanation, the better people will be able to help out.
This is the full table list:
It was recommended that I have (for instance) the tblHBCase table and to link tblCaseAssets, I have a tblKeyHBCaseAssets table to link them. Normally I would have an FK in tblCaseAssets to the tblHBCase PK. The issue is that 1 asset could be used in multiple cases. For this reason, I need to be able to link any case to any asset at any time.
I am trying to create the front end forms in Access. I don't understand how to update the key tables and link the joining tables based on the key table. Does this make sense?
I have a link to an image of the schema too, in case that helps. The backend tables are in SQL.
Thank you for any help!
