Hello All, Using PostgreSQL 9.6.2 on a Windows 64bit platform. I am about to start a new software development dealing with warehouse operations. Software should handle multi-company structure. There will be single company starting to use the software at the beginning. I need to decide between below scenarios before I develop any database structure. Biggest table I am assuming will be inventory movements table. I am expecting about 90% of the queries will run on that table. I do not see that table to have more than 100.000 rows in a year for a single company. I am not planning to have a new database for each year. Data will pile up in time. My current scenarios are: 1) Separate company records by adding a field in each table and keeping all records in a single database and schema. (Queries will be easier to build and run) 2) Separate company records by adding a new schema for each company there may be keeping all records in a single database. (Queries will need UNION across schemas for corporate reports) 3) Separate company records by creating a new database for each company. (This option, I do not want to do. Will think about corporate reports if I have to select this one). I appreciate any suggestion on above possible options. New suggestions, experience sharing are always welcome.
