mORMot REST Object-Relational-Mapping ORM Units

Folder Content

This folder hosts the RESTful ORM high-level features of the mORMot Open Source framework, version 2.

ORM/ODM Features

mORMot implements a simple and very efficient Object-Relational-Mapping:

  • The parent TOrm class give access to ORM methods at object level;
  • IRestOrm IRestOrmServer IRestOrmClient interfaces can be used in business code for abstract and persistent-agnostic data access;
  • UTF-8 and JSON are used from the ground up, to make our ORM easy to consume in a REST approach, as defined in the /src/rest folder;
  • It can leverage SQLite3 as its kernel, to access several data sources over virtual tables;
  • A high-performance in-memory engine, using JSON or binary on disk, can be used instead of SQLite3;
  • Switch to a NoSQL database like MongoDB is possible, transforming our ORM to an ODM - aka Object-Document-Mapping.

Units Presentation

mormot.orm.base

Low-Level Basic Types and Definitions for our RESTful ORM

  • Shared ORM/JSON Fields and Values Definitions
  • ORM Ready UTF-8 Comparison Functions
  • TOrmWriter Class for TOrm Serialization
  • TOrmPropInfo ORM / RTTI Classes
  • Abstract TOrmTableAbstract Parent Class
  • TOrmTableRowVariant Custom Variant Type
  • TOrmLocks and TOrmCacheTable Basic Structures

mormot.orm.core

Main Shared Types and Definitions for our RESTful ORM

  • ORM Specific TOrmPropInfoRtti Classes
  • IRestOrm IRestOrmServer IRestOrmClient Definitions
  • TOrm Definition
  • RecordRef Wrapper Definition
  • TOrmTable TOrmTableJson Definitions
  • TOrmMany Definition
  • TOrmVirtual Definitions
  • TOrmProperties Definitions
  • TOrmModel TOrmModelProperties Definitions
  • TOrmCache Definition
  • TRestBatch TRestBatchLocked Definitions
  • TSynValidateRest TSynValidateUniqueField Definitions
  • TOrmAccessRights Definition
  • TOrm High-Level Parents

This unit is not depending from mormot.rest.core so can be used as a pure ORM layer for your projects.

The IRestOrm interface is the main SOLID entry point of all ORM process.
