## worked on so far
|
|
|
|
setup
|
|
----------------------------------------------------------------------------------------------------------------------------------------------------
|
|
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.
|
|
the goal then is to break that back apart to whatever degree is necessary.
|
|
|
|
* _**run**_ `schema.sql` and `perd.sql` to setup basic tables
|
|
* create a table fc.live as copied from target (will need to have columns `version` and `iter` added if not existing)
|
|
* _**run**_ `target_info.sql` to populate the `fc.target_meta` table that holds all the columns and their roles
|
|
* fill in flags on table `fc.target_meta` to show how the data is related
|
|
* _**run**_ `build_master_tables.sql` to generate foreign key based master data
|
|
|
|
|
|
routes
|
|
----------------------------------------------------------------------------------------------------------------------------------------------------
|
|
* all routes would be tied to an underlying sql that builds the incremental rows
|
|
* that piece of sql will have to be build based on the particular sales layout
|
|
* **columns:** a function to build the columns for each route
|
|
* **where** a function to build the where clause will be required for each route
|
|
* the result of above will get piped into a master function that build the final sql
|
|
* the master function will need to be called to build the sql statements into files of the project
|
|
|
|
|
|
route baseline
|
|
----------------------------------------------------------------------------------------------------------------------------------------------------
|
|
* forecast = baseline (copied verbatim from actuals and increment the dates) + diffs. if orders are canceled this will show up as differ to baseline
|
|
* regular updates to baseline may be required to keep up with canceled/altered orders
|
|
* copy some period of actual sales and increment all the dates to serve as a baseline forecast
