Ad-hoc and Audit Support

Introduction

Ad-hoc data retrieval and audit support are critical functions for organizations seeking to gain insights from their data and maintain compliance. Teradata, a powerful data warehouse and analytics platform, plays a pivotal role in enabling businesses to efficiently provide data for requested periods and filters, ensuring data-driven decision-making and regulatory compliance. This technical document explores the key technologies and processes involved in leveraging Teradata for ad-hoc and audit support.

Key Technologies:

Teradata Database:
- Teradata’s massively parallel processing (MPP) architecture offers high-performance data storage and processing capabilities, making it ideal for handling large datasets and complex queries.
SQL (Structured Query Language):
- SQL is the primary language used to query Teradata databases, allowing users to extract, filter, and manipulate data with ease.
Teradata Tools and Utilities:
- Teradata provides a suite of tools and utilities, such as Teradata Studio, Teradata QueryGrid, and Teradata Data Mover, to streamline data retrieval and transfer processes.
Teradata Indexes:
- Properly designed indexes improve query performance by accelerating data retrieval, which is vital for ad-hoc queries.
Teradata Query Optimization:
- Teradata’s query optimizer ensures efficient execution plans for complex queries, reducing processing time.

Ad-hoc Data Retrieval Process:

Data Request

Users submit ad-hoc data requests specifying the desired time periods, filters, and required data fields.

Query Design

Data analysts and administrators create SQL queries tailored to the request, ensuring optimal performance by using indexes and optimized query structures.

Query Execution

The SQL query is executed against the Teradata database, and the results are generated.

Data Presentation

The retrieved data is presented to the requesting party through reporting tools or in a format compatible with their needs.

Audit Support Process:

Audit Request: Audit support typically involves extracting historical data to ensure regulatory compliance or investigate specific events.
Data Retrieval: Data administrators access historical data within Teradata, often from data archives, and extract the relevant information based on the audit request.
Data Verification: Extracted data is compared with the source data to ensure accuracy and integrity.
Audit Documentation: A detailed audit report is generated, highlighting the findings and outcomes of the audit.
