# EMQX Oracle Database Bridge
|
||||||
|
|
||||||
|
This application houses the Oracle Database bridge for EMQX Enterprise Edition.
|
||||||
|
It implements the data bridge APIs for interacting with an Oracle Database Bridge.
|
||||||
|
|
||||||
|
|
||||||
|
# Documentation
|
||||||
|
|
||||||
|
- Refer to [EMQX Rules](https://docs.emqx.com/en/enterprise/v5.0/data-integration/rules.html)
|
||||||
|
for the EMQX rules engine introduction.
|
||||||
|
|
||||||
|
|
||||||
|
# HTTP APIs
|
||||||
|
|
||||||
|
- Several APIs are provided for bridge management, which includes create bridge,
|
||||||
|
update bridge, get bridge, stop or restart bridge and list bridges etc.
|
||||||
|
|
||||||
|
Refer to [API Docs - Bridges](https://docs.emqx.com/en/enterprise/v5.0/admin/api-docs.html#tag/Bridges) for more detailed information.

# Oracle Database Connector
|
||||||
|
|
||||||
|
This application houses the Oracle Database connector for EMQX Enterprise Edition.
|
||||||
|
It provides the APIs to connect to Oracle Database.
|
||||||
|
|
||||||
|
So far it is only used to insert messages as data bridge.
