# Introduction
The BoxLang ORM module allows your BoxLang application to integrate with the powerful Hibernate ORM
## BoxLang ORM
The [BoxLang ORM module](https://github.com/ortus-boxlang/bx-orm) allows your BoxLang\
application to integrate with the powerful [Hibernate ORM](https://hibernate.org/orm/). With Hibernate, you can interact with your database records in an object oriented fashion, using a BoxLang class to denote each record and simple getters and setters for each field value:
```js
class entityName="Auto" persistent="true" {
property name="id" type="string" fieldtype="id" ormtype="string";
property name="make" type="string";
property name="model" type="string";
function preInsert( entity ){
writeLog( "Inserting new Auto: #getMake()# #getModel()#" );
}
}
```
BoxLang ORM also enables transactional persistence, where an error during a save will roll back the entire transaction to prevent leaving the database in a broken state:
```js
transaction{
try{
entitySave(
entityNew( "Purchase", {
productID : "123-expensive-watch",
purchaseTime : now(),
customerID : customer.getId()
})
);
var cartProducts = entityLoad( "CartProduct", customer.getID() );
entityDelete( cartProducts );
} catch ( any e ){
// don't clear the user's cart if the purchase failed
transactionRollback();
rethrow;
}
}
```
### Hibernate Version Support
bx-orm bundles Hibernate ORM `7.4.8.Final`.
### Open Source Product
bx-orm is an open source BoxLang module with no license purchase necessary. If you are looking to further the development of this extension, consider [sponsoring a feature or opening a support contract](#support).
### Features In A Nutshell
* Map BoxLang classes to database tables and work with rows as objects, with generated getters and setters.
* 47 built-in functions (BIFs) to create, load, save, delete, query and inspect entities (`entityNew()`, `entitySave()`, `entityLoad()`, `ormExecuteQuery()`, ...).
* A fluent query builder, `entityCriteria()`, with automatic joins, projections, paging and bulk statements.
* Entities as structs for JSON APIs with `entityToStruct()`, compatible with mementifier's `this.memento`.
* Entities as queries for reports, grids and exports with `entityToQuery()`. See [Entities as Queries](/bxorm-2.x/working-with-entities/queries.md).
* ORM work shares BoxLang's `transaction{}`, so ORM writes and plain SQL commit or roll back together.
* Soft delete, automatic timestamps, pessimistic locking, read-only loads and a second-level cache.
* Entity events (`preInsert()`, `postUpdate()`, `postCommit()`, ...) with the power to veto a write.
* Clear `orm.*` errors that name your entities and say how to fix the problem, plus `ormDiagnostics()`.
* A boot cache that lets production start without parsing a single entity.
* Supports every database Hibernate supports, from MySQL, MariaDB and PostgreSQL to SQL Server, Oracle and SQLite.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://bxorm.ortusbooks.com/bxorm-2.x/introduction.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
