# Log trigger

**Log trigger** is a a pattern to create a [trigger](https://en.wikipedia.org/wiki/Database_trigger) to automatically store historical information

of a table in a relational database.

It works on a parallel table, creating infomation in a scheme of [tuple versioning](https://en.wikipedia.org/wiki/Tuple-versioning).

More detailed information: Log trigger in [Wikipedia](https://en.wikipedia.org/wiki/Log_trigger).

## Repository

The intention of this repository is to mantain the definition of the **Log trigger** in as many database providers as possible,

given that they use very different syntax and semantics, specially for triggers.

Currently, we have the defintition for the following database providers:

* **IBM DB2**

* **Microsoft SQL Server**

* **MySQL**

* **Oracle**
