Prepare
- Upload Teradata files
Teradata is a massively parallel (MPP) data warehouse relational database system designed for large-scale analytics applications.
Why Agent Required
Teradata databases run on enterprise data warehouse systems that cannot directly upload data to the web. The DataMeans Agent connects securely to your Teradata environment for extraction.
What You Can Extract
- Teradata versions 12.x through current
- Tables, views, and materialized views
- Indexes and constraints
- Stored procedures (documentation)
What You Get Out
DataMeans extracts your data into multiple modern formats:
| Output | Description |
|---|---|
csv/{TableName}.csv | One CSV file per table with all row data |
xlsx/{TableName}.xlsx | Excel workbook per table |
xls/{TableName}.xls | Legacy Excel format per table |
json/{TableName}.json | JSON array of records per table |
json/{TableName}.jsonl | Newline-delimited JSON (streaming-friendly) |
postgres.sql | PostgreSQL CREATE TABLE + INSERT statements |
schema/schema-graph.json | Relationship graph for visualization |
schema/er-model.json | ER model for diagram tools |
report.json | Structured extraction report |
report.md | Human-readable extraction summary |
