Hi, I'm sorry if the question is a bit long, but I need to describe the set up.
I have to following type of database in mysql that I would like to convert to a mart: ------------------------ A "gene table" with the following columns: - gene id - gene name - sequence ... ------------------------ A "rna_gene table" with: - rna_gene_id - rna_id - gene_id ... A "rna table" with - rna_id - description ... ------------------------ A "reaction_gene table" with: - reaction_gene_id - reaction_id - gene_id ... A "reaction table" with - reaction_id - description ... ------------------------ If, when using martbuider I select only the 'gene' table to build the dataset, the corresponding mart does not include data from the "rna" and "reaction" tables. If, I select the tables "gene", "rna" and "reaction" tables to build the dataset, I get two datasets: one where I could filter by gene and rna and the other that I can filter by gene and reaction So, is there a way to build a single dataset so I can filter by gene, rna and reaction? This is a made up example, in the real database there are many more tables, but all follow this structure.
