Data Modeling

Data modeling tools have been conceived as database design tools to be use by data architects and database administrator to design logical and physical data models generating DDL. Although many of these data modeling tools are rather used to document (create a data model) of existing databases. Talend Data Catalog offers a different approach than traditional data modeling tool:

• The glossary driven methodology allows for immediate reuse and creation of terms and naming standards on the fly, fast tracking the data store documentation process
• The Web enabled tool offers better access than desktop tools
• The Data Modeling / Diagramming capabilities of the Talend Data Catalog are similar to conventional data modeling tools
• Data modeling is not limited to relational (RDBMS) database modeling, but also supports hierarchical (NoSQL) databases, and object stores (e.g. JSON in Amazon S3).

In addition, Talend Data Catalog has a glossary application that allows one to manage terminology and domain definitions across the enterprise. One can reuse these definitions not only among different enterprise applications but between versions of the same application.

A Naming Standard may be used to collect and apply naming standards based upon the name assignments made when editing a model.

In addition, the Talend Data Catalog allows one to link tables and columns to terms and glossary domains and business rules.

All the above may be accomplished with all the kinds of models and objects in Talend Data Catalog .
