Teradata Control Framework

The Control Framework is a set of architectural standards, development methods, processing patterns and a code library that provides the basis for implementing a true time variant data warehouse.

•The Control Framework is an automated framework to manage the ELT processes of the Teradata Global Architecture (3 Tier EDW) to ensure accuracy and efficiency.

>The Control Framework is used in conjunction with an ELT tool – in itself it is not a tool nor a replacement for a tool.

•The Control Framework enforces audit trail and reduces programmer effort.

•The Control Framework consists of the following components.

>Process Control Data Model and standard processing columns for all cross functional model tables.

>Standard code modules for ELT processes, surrogate keys and reference code data management .

>House keeping utilities for the daily/intraday control of the ELT processes

•The Control Framework is a Teradata Professional Services Consulting Asset that is available for purchase by Teradata customers.

Control Framework Control Patterns:

Start of Day

>Opens the business date for a given stream of ELT

•Start of Stream

>Opens the stream instance within a business date for a specific ELT batch

•End of Stream

>Completes the stream instance

•End of Day

>Completes the business date for a given stream

•Register Source File Extract

>Registers the availability of source data in the landing queue.


STREAM Concept

•A Stream is a collection of processes that must be completed as a whole to meaningfully transform a set of input data (files or tables) into a coherent output set of tables within the data warehouse. Each collection of dependent processes is identified by a record in this table.

•A Stream is a unit of schedulable work. Once completed a Stream may not be re-run without intervention to revert output data and CTLFW metadata to the pre-run state.

•There is no limit to the number of times a Stream may be run on any given date. Only one instance of any Stream is allowed to be run at a time.

Control Framework Components:

•Data Model that holds processing metadata

>When, what program, what source, what target, update metrics

>Static metadata, eg System, Files, Paths

>Operational metadata collected by the Standard CTLFW code at run time, e.g. metrics…

•Standard Code for the processing, control and registration patterns

>Called and executed to read from and write to the CTLFW tables.





>Does the audit and control part of the process isolated from the individual pattern.
