I am seasoned SQLAlchemy user and quite good in node's sequelise ORM. But I am new to the one with Django.So here's my situation. I am developing an accounting (book keeping ) automation software service. So there are accounting rules (Debit = Dr and credit = Cr) for double entry book keeping. Every transaction will have 2 or more amounts, at least 1 each for dr or Cr. These entries are called vouchers. We also store retail bills, receipts and payments again all in different tables. But the bills and receipt&payment tables are connected to the voucher table. The software generates reports such as cash flow, meaning day's opening balance, total Drs, total crs, and final closing balance (DRs - Crs). then there are Profit and Loss as well as balance sheet reports. All this needs a lot of aggregations (sum and counts ) and also joining of invoice + voucher and recept&payment + voucher tables. so here are my questions. 1: given the fact that I have created materialised views in Postgresql, should I even care to model them and use the ORM syntax instead of raw query? What would perform better? 2: datasets are going to be huge some times in terms of shear rows (all transactions aka vouchers ) or some times sum and count will be used in complex queries on a huge dataset. Again, should I rely on raw queries or will ORM plan the queries for me better? Should I instead create stored procedures and call them from my REST API? talking of which, 3: I am using Django REST Framework and serialising records is an option to get json output. Should I use it or just go with raw queries and convert output to JSON as required? Again performance is a question. Tip, My team is very proficient in SQL and yours truely can modestly call himself an expert in the same, so maintenance is not an issue here. Regards.
