Where ( at what stage) does the work take place to make a database intuitive?

Consider the 4 fields " ProdCategory", ProdName", "ContainerSize" and ContainerType".

I want the end user to choose a ProdCategory and be given a drop down with 6 choices ( white, milk, flavored milk, cheese, yogurt, vegetables, cultured)

Having made the choice say " Cheese", the product name is dependent on my selections and gives a drop down of cheese names only.

Similarly containerSize then limits its drop down to sizes for the various cheeses and so on.

Am I jumping the gun and this is not a task for table design if so where does this task fit?

Thanks

Because of the small number of category choices a simple table lookup field rule would suffice. Otherwise create a "supporting" table that contains separate records for each "category". Create "supporting" tables for the product names. Each record would contain a category, and a product name. Use a table lookup field rule and define a filter based on the category. Create a "supporting" table for the container sizes. Each record would contain three fields, category, productname, and containersize. Define a table lookup field rule, using a filter based on category and productname.

Ok I think my situation calls for maximum 12 category choices. Assuming I want to use a lookup how ot I get there from table design and can you illustrate how I would create an actual lokup? I lean best by example.

Thanks

Clem,

I lean best by example.
As do I and many others.....do a search for "lookup" using quotes and then choose appropriate threads that have examples (paperclip icons next to them). There are many such examples already created by people attached to threads--think Alpha includes some too in the sample file it has.

Here is an example of filtered lookups based upon the field value from the previous field lookup as you were describing. See if this helps.

I should also have made the point that mine is a Quality database it will not be used say for orders but rather to manage suppliers (vendors). so we ( qA , marketing, sales, logistics ) can see who makes what , what the standards are , where vendors are located , what problems they have, etc.
