Getting Started

@rattus-orm/core provides the essential functionality for data interaction. In simple terms, there are four main concepts:

• Database – an object that ties all parts together;
• Model – a class describing the fields of a specific entity;
• Repository – a service for managing data of a particular Model;
• Query – a service for creating complex queries.

Each of these relies on a Data Provider – a separate class that establishes a connection with a storage system. The "core" package includes a provider for working with a standard JavaScript object (ObjectDataProvider).

With a data provider, you can connect the ORM to any synchronous data storage. It facilitates the main operations of reading and writing.

The optimization of interaction with a specific storage system also occurs at the data provider level. All methods of other parts of the application, in one way or another, refer to it.
