Teradata Parallel Data Pump

Glossary
Teradata SQL: Teradata Database dialect of the relational language SQL, having data
definition and data manipulation statements. For example, CREATE TABLE is a data
definition statement. A data manipulation statement is a data retrieval statement, such as
SELECT.
transaction: A set of Teradata SQL statements executed as a unit. All of the statements must
execute normally or else any changes made during the transaction are backed out and none of
the remaining statements in the transaction are executed. Teradata Database supports both
ANSI and Teradata transaction semantics.
trigger: One or more Teradata SQL statements associated with a table and executed when
specified conditions are met.
type: A column attribute that specifies the representation of data values for fields in that
column. Teradata SQL data types include numerics and strings.
U
UDF User-Defined Function. UDFs are extensions to Teradata SQL. Users can write UDFs
to analyze and transform data already stored in their data warehouse in ways that are beyond
the functionality of Teradata’s native functions.
UDM User-Defined Method. A custom function explicitly connected to a UDT.
Functionality applicable to a UDT can be located in the UDM associated with that UDT
instead of being replicated to all of the applications that use that UDT, simplifies maintenance.
UDT User-Defined Type. A collection of one or more data values organized into a single
customized data type and a set of methods that operates on those values.
user: In Teradata SQL, a database associated with a person who uses Teradata Database. The
database stores the person’s private information and accesses other Teradata Databases.
UPI: Unique primary index; a UPI is required and is typically assigned to major entities in
the database.
user: A person who uses Teradata Database. The database stores the person’s private
information and accesses other Teradata Databases.
UTF-8: Teradata’s 8-bit multi-byte character set used by Teradata Database to calculate an
export width based on column character set (Latin, Unicode, KanjiSJIS) and for the session.
For example "Col1 Char(100) Latin Character set" will be exported as 100 bytes for ASCII
session and 300 bytes in UTF8.
UTF-16
Teradata’s 16-bit multi-byte character set.
Z
z/Linux Linux operating system (RedHat or SuSE) compiled to run on IBM System z
machines.
