TS1329: '{0}' accepts too few arguments to be used as a decorator here. Did you mean to call it first and write '@{0}()'?

TS1340: Module '{0}' does not refer to a type, but is used as a type here. Did you mean 'typeof import('{0}')'?

ORM or Object-Relational Mapper maps objects to records in relational database tables (also sometimes referred to as relations, hence the name). Oracle, MySQL, and PostgreSQL are well-known relational databases.
ODM or Object-Document Mapper does the same for non-relational, document-based databases like MongoDB - it will map objects to documents.
In both cases the idea is to make persistence of objects in an object-oriented application as simple and transparent as possible - whatever kind of target database system you may be using for that persistence.
