# Overview

The integration between APM for PPM (APM) and Universal CMDB (UCMDB) enables you to share information from UCMDB with APM.

You can use the integration to automate the creation and update of requests in APM, freeing you from repetitive and manual input of information in APM. This also ensures that APM is kept up to date with real, accurate, discovered data in your environment.

The following table provides an overview of the APM integration with UCMDB:

Property | Details
--- | ---
Integration direction | From UCMDB to APM
Integration technology | Push adapter
Pushed data | CIs created in UCMDB are pushed to APM to create requests in APM
Universal CMDB adapter | APM Push Adapter (APMPushAdapter)

## How Data is Synchronized Between APM and UCMDB

When referring to the concept of data information, it is important to distinguish between a UCMDB CI (Configuration Item) and an APM Application. Both are defined in a different Data Model, and there must be a conversion before transferring CIs in UCMDB to Applications in APM.

The following graphic shows the high-level components of the integration:

Note: The Push Adapter is executed in the Data Flow Probe/Integration Service process.

UCMDB stores its information using CIs. The integration chooses which data to pull from UCMDB by defining integration TQL queries. Each TQL query defines a superset of data relevant for the integration.

The UCMDB Push Engine:

- Retrieves the required data from the UCMDB, using the given TQL query.

- Filters the data to include only the data that has changed since the last execution of this synchronization.

- Splits the data into multiple chunks without breaking consistency.

- Sends the information to the Probe/Adapter.

The Push Adapter is a generic framework for easily configuring push adapters, using only XML and Groovy. It allows easy mapping of the data from the UCMDB data model into the APM data model, and the transfer of this converted data into the APM database through REST APIs called from APM.

For more information about push adapter, see Developing Push Adapters in the Universal CMDB Developer Reference Guide.

For details about REST APIs that this integration call from APM, see REST APIs Called in the Integration.
