Concepts

pull various static files into postgres and do basic transformation without losing the original document or getting into custom code for each scenario

the is an in-between for an foreign data wrapper & custom programming

Storage

all records are jsonb applied mappings are in associated jsonb documents

Import

COPY function utilized

Mappings

  1. regular expressions are used to extract pieces of the json objects
  2. the results of the regular expressions are bumped up against a list of basic mappings and written to an associated jsonb document

each regex expression within a targeted pattern can be set to map or not. then the mapping items should be joined to map_rv with an = as opposed to @> to avoid duplication of rows

Transformation tools

  • COPY
  • regexp_matches()

Difficulties

Non standard file formats will require additional logic example: PNC loan balance and collateral CSV files

  1. External: Anything not in CSV should be converted external to Postgres and then imported as CSV
  2. Direct: Outside logic can be setup to push new records to tps.trans direct from non-csv fornmated sources or fdw sources

Interface

maybe start out in excel until it gets firmed up

  • list existing mappings
    • apply mappings to see what results come back
  • experiment with new mappings
