Teradata Sql Assistant (TSA)


Definition:
Teradata SQL Assistant (TSA), as part of Teradata Tools and Utilities (TTU), is an ODBC-based client utility used to access and manipulate data on ODBC-compliant database servers. It has two editions:
1) Teradata SQL Assistant for Microsoft Windows
2) Teradata SQL Assistant/Web Edition

Teradata SQL Assistant is an information discovery tool designed for Windows XP and Windows 2000. Teradata SQL Assistant retrieves data from any ODBC-compliant database server. The data can then be manipulated and stored on the desktop PC.

Teradata SQL Assistant/Web Edition is a web-based query tool that allows you to compose queries, submit them to the Teradata Database, and then view the results in a web browser.

Overview:
Teradata SQL Assistant for Microsoft Windows, originally called "Queryman" (before V. 6.0)or "QueryMan" (V. 6.0 and up), is also known as "SQLA" among programmers. It supports import / export tasks, but not the serious ones. With its user-friendly GUI, TSA for Windows is generally oriented to business users and casual data consumers. (Refer to BTEQ for comparison.) TSA / Web Edition has fewer functions than TSA for Windows. The key features of each are presented below.

The key features of Teradata SQL Assistant are:
    * Send queries to any ODBC database or the same query to many different databases;
    * Export data from the database to a file on a PC;
    * Create reports from any RDBMS that provides an ODBC interface;
    * Import data from a PC file directly to the database;
    * Use an import file to create many similar reports (query results or Answersets). For example, display the DDL (SQL) that was used to create a list of tables;
    * Create a historical record of the submitted SQL with timings and status information such as success or failure;
    * Use SQL syntax examples to tailor statements;
    * Use the Database Explorer Tree to easily view database objects;
    * Use a procedure builder that provides a list of valid statements for building the logic of a stored procedure;
    * Limit data returned to prevent runaway queries.

The key features of SQL Assistant / Web Edition are:
    * Send queries to any Teradata Database;
    * View and sort the results by column and save them to a file;
    * Save queries to a file so you can run them automatically from the same file in the future;
    * Load queries from a file and make changes before submitting them to the database;
    * View historical records of the queries you have submitted with timings and status information. You can sort the history rows by column, update them with your notes, and save the records to a file;
    * View a hierarchical listing of databases with object names to reduce the time required to create SQL statements;
    * Use the browser’s built-in find features to do a string search on a query, an answer set, or any information in the historical table visible in the browser window;
    * Abort a query in progress if you change your mind about running a query or if a query is taking longer than you expected;
    * Client browser’s connection ends after 30 minutes of inactivity.

BYNET

DEFINITION BYNET, acronym for "BanYan NETwork," is a folded banyan switching network built upon the capacity of the YNET. It acts as a distributed multi-fabric inter-connect to link PEs, AMPs and nodes on a Massively Parallel Processing (MPP) system. OVERVIEW Interconnect technology is important for parallel computing. The BYNET is Teradata's "system interconnect for high-speed, fault tolerant warehouse-optimized messaging between nodes." [11] As an indispensable part of the Teradata MPP system, it can be understood better with its predecessor "YNET" in the background. In 1982, the YNET interconnecting technology used on the DBC 1012 was patented for the parallelism. As a broadcast-based hardware solution, it linked all the IFPs, COPs, and AMPs together with circuit boards and cables in a dual bus architecture. Two costom-built busses operated concurrently within the interconnect framework: YNET A to connect the IFPs and COPs on one side, and YNET

SET VS MULTISET

Table Type Specifications of SET VS MULTISET There are two different table type philosophies so there are two different type tables. They are SET and MULTISET. It has been said, “A man with one watch knows the time, but a man with two watches is never sure”. When Teradata was originally designed it did not allow duplicate rows in a table. If any row in the same table had the same values in every column Teradata would throw one of the rows out. They believed a second row was a mistake. Why would someone need two watches and why would someone need two rows exactly the same? This is SET theory and a SET table kicks out duplicate rows. The ANSI standard believed in a different philosophy. If two rows are entered into a table that are exact duplicates then this is acceptable. If a person wants to wear two watches then they probably have a good reason. This is a MULTISET table and duplicate rows are allowed. If you do not specify SET or MULTISET, one is used as a default. Here is the issue:

Datawarehousing Concepts

Data warehousing : Data warehousing is combining data from multiple and usually varied sources into one comprehensive and easily manipulated database. Common accessing systems of data warehousing include queries, analysis and reporting. Because data warehousing creates one database in the end, the number of sources can be anything you want it to be, provided that the system can handle the volume, of course. The final result, however, is homogeneous data , which can be more easily manipulated. Data warehousing is comprised of two primary tools: databases and hardware. In a data warehouse, there are multiple databases and data tables used to store information. These tables are related to each other through the use of common information or keys. The size of a data warehouse is limited by the storage capacity of the hardware. The hardware required for a data warehouse includes a server, hard drives, and processors. In most organizations, the data warehouse is accessible via the sh
