With MPP architecture for Quick load and fast query results. Teradata is mostly used by Fortune 500 Companies due to its high Cost. The MPP architecture patented technology which Teradata brings with its AMP nodes (as explained below) gives it optimum amount of parallelism. Teradata AMP configuration requires highly specialized Engineers coming directly from Teradata. This parallelism and Configuration as well infrastructure requirements makes it high cost technology to acquire for any medium size vendors. Although Teradata is also used to OLTP but its most optimum well before Oracle 10g came with Grids and RAC real application clusters amounting load balancing of query processing loads among multiple nodes as well parallelism. Teradata Utilizes program driven ETL tools. The Extract-Fetch-Load and processing cycle is all maintained by program driven ETL utilizes. As Explained below: SQL standards used by Teradata : SQL ’92 , SQL’99 , SQL 2003. The latest is SQL-2008 many organizations and products are still maintain SQL 2003 standards. If you look at most Job SQL 2008 is hot skill. This Real time data justifies that see yellow line. Teradata was among the quickest to implement latest SQL standards.

Like in Oracle we have (+) proprietary symbol for left or right outer join But This is not portable to let us say SQL Server or Informix( As they do not have this syntax). Using ANSI syntax like <table A> left outer join <table B> on A.key = B.key instead as in Oracle select * from <table A>(+) join <table B> PROPERITORY SYNTAX. Using ANSI syntax is One of The Important BEST PRACTISES for code interoperability. (MPP) Massive parallel processing AMP manages Disk Each Disk stores part of database offering parallelism. parser (done by Parsing Engine in short called PE)-> BYNET-AMP-DISK Diagram 1: : BTEQ: BTEQ scripts can be customized/coded to allow source to target mapping and transformation. Command based tool where we can write scripts to import or export data. TPT: Teradata Parallel Transporter

High level of performance for load data from source to target can be achieved. Fast Export: High speed utility for Quick export of data. Multi load: Load from multiple disparate data sources. Teradata gives PLSQL like facility to write Functions, procedure, code block which are utilized by The 5 ETL utilities provided by Teradata for Every step of Extract, transport and Load cycle.
