I have a SQLite database. Should I put the DB in a data structure with Core Data. How can I do? My problem is “z relations” between tables.
It’s possible?

I found a solution. In the future, should I use SQLite directly, but for those who have a similar problem to mine this solution works well.
Step 1: Core Data in your table add column headed gl’ID temporary relations of the original table.
Step 2: In the data in CSV add two columns. The first column contains the value 1 and refers to P_OPT of Core Data and the second column contains the identifier of the table and retrieved P_ENT generated by reading the SQLite Core Data in the table Z_PRIMARYKEY.
Step 3: With any editor Mac transfer your data in SQLite files generated by Core Data. Remember to attach gl’ID (relations) in the temporary columns.
Step 4: Through the use of the SQL UPDATE command (works with any SQL editor on the Mac) updates all ID columns of relations in Core Data with the value Z_PK. The value retrieved by the queries and the use of temporary columns.
Sorry for the bad English. I hope not to have been convoluted with the explanation and useful to others.
