Teradata Warehouse Diagrams and Documentation

DbSchema gives Teradata teams a design-first workflow: import the existing schema as an interactive ER diagram, refine it visually, and ship every change as a reviewed SQL script.

Built for enterprise schema governance, change review, and cross-environment consistency, with an offline model you can keep in Git, team collaboration, and documentation that developers, analysts, and stakeholders can navigate in minutes.

Schema Visualization for Teradata Data Warehouses

Teradata is an enterprise data warehouse platform that organizes data using user-based schema ownership, primary index (PI) and unique primary index (UPI) distribution strategies, and multi-value compression. In large Teradata deployments, hundreds of user schemas and thousands of tables make manual navigation through system views impractical. DbSchema connects to Teradata via JDBC, reads the data dictionary, and renders cross-database relationships as interactive ER diagrams that DBA teams can explore and share.

ER Diagrams Across Teradata Databases and User Schemas

DbSchema lets you pull tables from multiple Teradata databases and user schemas onto a single diagram canvas, making it straightforward to document data mart structures, staging layers, and cross-schema dependencies common in Teradata warehouse architectures. Because the diagram is built directly from the data dictionary, it reflects primary index and unique primary index distribution choices as part of the same visual model your DBA team already reasons about.

Teradata SQL Client Built Into DbSchema

The DbSchema SQL editor connects directly to your Teradata system and supports Teradata SQL syntax, including BTEQ-compatible statements, SET/MULTISET table semantics, and analytic functions. Execute queries, browse result sets, and export data without maintaining a separate Teradata client tool alongside your schema designer.

Schema Documentation for Teradata DBA Teams

DbSchema generates complete HTML schema documentation from your Teradata data dictionary, covering table definitions, column types, primary indexes, partitioning expressions, and referential constraints. Exporting this documentation helps DBA teams maintain data catalog standards and satisfy data governance requirements without building custom documentation tooling. The same offline model can also be compared against a second Teradata environment to generate a migration script instead of writing ALTER statements by hand.

How to Connect DbSchema to Teradata

A Teradata connection profile takes a few minutes to set up:

  1. Download and install DbSchema — no signup required.
  2. Download the Teradata JDBC driver from the Teradata Downloads portal (developer.teradata.com) and register it in DbSchema under Connections > Manage Drivers.
  3. Start a new connection, choose Teradata, and enter the host together with the default port 1025, matching the JDBC URL format jdbc:teradata://host/DATABASE=dbname,DBS_PORT=1025.
  4. Provide credentials — LDAP and Kerberos parameters can be appended to the JDBC URL if your deployment requires them.
  5. Connect to pull the data dictionary and generate the first cross-database diagram.

When connecting to Teradata on AWS or Azure, use the VPC endpoint hostname rather than a public IP.

Reasons Teradata Teams Choose DbSchema

  • Map complex Teradata data warehouse schemas with cross-user and cross-database ER diagrams
  • Run Teradata SQL queries without requiring a full Teradata Tools and Utilities installation
  • Generate and share schema documentation for data warehouse governance and auditing
  • Compare schema structures between Teradata development and production environments
  • Store schema snapshots locally and review them without an active Teradata connection
