Data dictionary

As explained in AI for Everyday IT

A data dictionary is a structured reference describing the objects, columns, data types, and other metadata in a data system.

A data dictionary is a reference for the tables, columns, data types, and other metadata in a data system. Supplying it to an AI chatbot gives the chatbot the schema context needed to write more accurate queries, especially when the system is unfamiliar or poorly represented in its training data. section 10.5 section 10.6.2

Use a data dictionary when asking for database queries:

  • Provide the table and column definitions, or supply equivalent DDL. section 10.6.2
  • Add a basic query or sample output when the desired result is difficult to describe. section 10.6.2
  • Review generated SQL carefully; without schema information, a chatbot may invent tables and columns that do not exist. section 10.5

Memory-configuration query

Give the chatbot the inventory schema and request a query that identifies improper Oracle memory configurations. A supplied view can expose server name, database name, memory targets, and physical memory; the generated SQL can then convert values such as 6G and 2000M into comparable megabytes. section 10.6.2

How AI for Everyday IT covers it

How deep it goes
Defines schema context and prompt inputs, but stops short of independently validating generated SQL or guaranteeing correct results.
Examples
Uses Commvault metadata and an Oracle memory-configuration view with sample rows and conversion queries.
What it assumes
Assumes basic database administration knowledge and access to reliable table definitions, column metadata, or DDL.
What you can do after
Diagnose database configurations by prompting for queries grounded in supplied schemas, then reviewing the resulting SQL.
How it connects
Connects database schemas, DDL, SQL queries, database maintenance, and inventory reporting.
