SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Quickly discover and understand the structure of a relational database so you can find relevant tables, columns, and relationships without manually inspecting schemas or guessing join paths.

Core Features & Use Cases

  • List available tables and provide brief descriptions of their purpose to orient users to the dataset.
  • Describe table schemas with column names, data types, primary keys, foreign keys, and short sample rows to illustrate content.
  • Map relationships and join paths by identifying Id-suffixed foreign keys and tracing parent-child chains to support query building and analytics workflows.
  • Use Case: Determine which tables to join and what keys to use when calculating revenue by artist or when extracting customer contact information for reporting.

Quick Start

Use the schema-exploration skill to list all tables and then describe the Customer table with columns, types, keys, and example rows.

FAQPage Schema
How do I map database schema and table relationships for SQL queries?

Map database schema by listing available tables and describing columns, data types, primary keys, and foreign keys. This process traces parent-child join paths to support relational database query building and data discovery.

What is the best way to discover foreign key join paths in a relational database?

Discover foreign key join paths by identifying Id-suffixed foreign key columns and tracing parent-child chains. This maps table relationships, clarifying which tables to join and what keys to use for analytics workflows.

How do I list all tables and inspect column data types in a SQL database?

List all tables and inspect column data types by applying schema discovery tools to the relational database. This produces clear summaries of table purposes, column names, primary keys, and sample rows to orient users to the dataset.

Do I need specific tools to explore database structure and sample rows?

Exploring database structure and sampling rows requires access to sql_db_list_tables and sql_db_schema tools. These tools enable the extraction of table schemas, column data types, and short sample rows to illustrate content.

Can I sample rows from tables while mapping database schema?

Sample rows from tables while mapping database schema to illustrate content alongside column names and data types. This provides immediate context for the data stored within specific tables during the data discovery process.

What are the limitations of using schema exploration for data discovery?

Schema exploration for data discovery is limited to relational databases and relies strictly on sql_db_list_tables and sql_db_schema tools. It focuses on structure and sampling rather than executing complex data transformations or analytics queries.
