A physical representation of data of the staging tables. You can create, edit, and delete physical data objects. When you configure the Informatica platform staging process, the synchronization process creates physical data objects with the name

C_<

staging table name

>

. One of the physical data objects that the synchronization process creates is a customized data object that is reusable with one or more relational resources.

A model that describes the structure and flow of data into the staging table. The synchronization process creates one logical data object model for each staging table in the

MDM Hub

. The logical data object model has the name

C_<

staging table name

>_Model

. The model contains logical data objects and a mapplet. You can edit and delete logical data objects and the mapplet in a logical data object model.

An object in a logical data object model that describes an

MDM Hub

staging table. When you synchronize the Model repository with the

MDM Hub

metadata, the synchronization creates one logical data object with the name

C_<

staging table name

>_LDO

. The logical data object contains a logical data object read mapping and a logical data object write mapping.

Contains physical data objects as input and a logical data object as output. In a mapping, the Data Integration Service reads data from the mapping source and makes the data available to view in the logical data object read mapping.

Contains a logical data object as input. The logical data object write mapping writes to the target staging table in the

Hub Store

. In a mapping, the Data Integration Service processes the data through a mapplet before the mapping writes to the

MDM Hub

staging table.

A reusable object that contains an input transformation and an output transformation. The input transformation can connect to an upstream transformation in a mapping to fetch source data. The output transformation can connect to a downstream transformation in the mapping to transfer the transformed data to the target staging tables. When you synchronize the Model repository with the

MDM Hub

metadata, the synchronization creates mapplets with the name

C_<

staging table name

>_Mapplet

. You can edit and delete mapplets.

A physical representation of source data. You can create, edit, and delete physical data objects. You need to create physical data objects to connect to the source data.

A set of inputs and outputs that represent the data flow between sources and target staging tables. Mappings can be linked by transformation objects that define the rules for data transformation. The Data Integration Service uses the instructions that you configure in the mapping to read data from the source, transform the data, and write data to staging tables.
