+# Oracle source (contrib)
+
+## Description
+
+Oracle data sources are Oracle database tables.
+These are specified by a table reference (e.g. `"TRANSACTION_FEATURES"` or `"SCHEMA.TABLE"`).
+
+## Disclaimer
+
+The Oracle data source does not achieve full test coverage.
+Please do not assume complete stability.
+
+## Examples
+
+Defining an Oracle source:
+
+```python
+from feast.infra.offline_stores.contrib.oracle_offline_store.oracle_source import (
+    OracleSource,
+)
+
+driver_stats_source = OracleSource(
+    name="driver_hourly_stats",
+    table_ref="DRIVER_HOURLY_STATS",
+    event_timestamp_column="EVENT_TIMESTAMP",
+    created_timestamp_column="CREATED",
+)
+```
+
+**Note:** Oracle stores unquoted identifiers in uppercase. Reference columns using the casing shown by Oracle (e.g. `USER_ID` for unquoted identifiers).
+
+## Supported Types
+
+Oracle data sources support standard Oracle numeric, string, date, and timestamp types mapped through the ibis Oracle backend.
+For a comparison against other batch data sources, please see [here](overview.md#functionality-matrix).

+# Oracle offline store (contrib)
+
+## Description
+
+The Oracle offline store provides support for reading [OracleSources](../data-sources/oracle.md).
+* Entity dataframes can be provided as a SQL query or as a Pandas dataframe.
+* Uses the [ibis](https://ibis-project.org/) Oracle backend (`ibis.oracle`) for all database interactions.
+* Only one of `service_name`, `sid`, or `dsn` may be set in the configuration.
+
+## Disclaimer
+
+The Oracle offline store does not achieve full test coverage.
+Please do not assume complete stability.
+
+## Getting started
+
+Install the Oracle extras:
+
+```bash
+pip install 'feast[oracle]'
+```
+
+## Example
+
+{% code title="feature_store.yaml" %}
+```yaml
+project: my_project
+registry: data/registry.db
+provider: local
+offline_store:
+  type: oracle
+  host: DB_HOST
+  port: 1521
+  user: DB_USERNAME
+  password: DB_PASSWORD
+  service_name: ORCL
+online_store:
+  path: data/online_store.db
+```
+{% endcode %}
+
+Connection can alternatively use `sid` or `dsn` instead of `service_name`:
+
+```yaml
+# Using SID
+offline_store:
+  type: oracle
+  host: DB_HOST
+  port: 1521
+  user: DB_USERNAME
+  password: DB_PASSWORD
+  sid: ORCL
+
+# Using DSN
+offline_store:
+  type: oracle
+  host: DB_HOST
+  port: 1521
+  user: DB_USERNAME
+  password: DB_PASSWORD
+  dsn: "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=DB_HOST)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ORCL)))"
+```
+
+### Configuration reference
