-the basic assumption is a single sales table is available to work with that has a lot of related data that came from master data tables originally.
+* setup the application tables `$PGD -f setup_sql/schema.sql`
-the goal then is to break that back apart to whatever degree is necessary.
+* create a table of data to forecast
-
+* edit `target_info.sql` to reflect the name of the table from previous step
-* _**run**_ `schema.sql` and `perd.sql` to setup basic tables
+* `$PGD -f setup_sql/target_info.sql` to populate the meta table
-* create a table fc.live as copied from target (will need to have columns `version` and `iter` added if not existing)
+* fill out the `target_meta` table in the database to model the forecast table
-* _**run**_ `target_info.sql` to populate the `fc.target_meta` table that holds all the columns and their roles
+* `PGD -f setup_sql/build_maste_tables.sql` to create master data tables from forecast data
-* fill in flags on table `fc.target_meta` to show how the data is related
+* `./routes/baseline/generate_route_sql.sh` to create the baseline sql used by the /baseline route
-* _**run**_ `build_master_tables.sql` to generate foreign key based master data
