Question

I need advise wish scenario is most efficient to represent my data

Table (A) fields:

ID (key), width (number), Height (number)

Table (B) fields:

ID (key), description (string), price (number)

Table (A) that have most of the basic data but one record from this table can have multi records from table (B)

For example: record A2 can have B1, B2 while record A3 can have B2, B3, B4

Now should I use master / detail 1 to many relation ? in this case the user will repeat entering the same “description” field from Table (B) for each similar value

or I should create a third table (AB) to hold the related data from both A and B ?

Thanks

Answer 1

in this case the user will repeat entering the same “description” field from Table (B) for each similar value

I don’t know what you mean by this but to me it looks like a typical many to many relation (A2 has B1, B2 and B2 has A2, A3). In that case, I would suggest creating the third “(AB)” table.
