# Data Integration Operations Mart

The Data Integration Operations Mart is a centralized data mart that stores job or transformation log data for auditing, reporting, and analysis. You can use the Data Integration Operations Mart to collect and query Data Integration log data. Then use the Pentaho Server tools to examine the log data in reports, charts, and dashboards.

The data mart is a collection of tables organized as a data warehouse using a star schema. Together, the dimension tables and a fact table represent the logging data. These tables must be created in the Data Integration Operations Mart database. Pentaho provides SQL scripts to create these tables for the PostgreSQL database. A Data Integration job populates the time and date dimensions.

**Note:** For optimal performance, be sure to [clean the operations mart](/pdia-admin/9.3-administer/optimize-the-pentaho-system/monitoring-system-performance/pentaho-operations-mart/data-integration-operations-mart/clean-up-operations-mart-tables.md) periodically.

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pdia-admin/9.3-administer/optimize-the-pentaho-system/monitoring-system-performance/pentaho-operations-mart/data-integration-operations-mart.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
