SQL object
SQL object. A NonStop SQL/MP database entity that is created, manipulated, or dropped by
SQL statements and that is described in an SQL catalog. Tables, views, indexes,
collations, and constraints are SQL objects.
SQLCI (NonStop SQL/MP conversational interface. A line-oriented terminal interface that
provides interactive SQL statements, SQLCI commands, a report-writing facility, and a
full set of utilities that provide quick access to information about the database, the data
dictionary, and the application programs.
Structured Query Language (SQL). A relational database language used to define,
manipulate, and control databases.
subdevice. A recipient of requests within a subsystem. A subdevice often corresponds to a
real external entity.
Subsystem Control Facility (SCF). A management application within the Distributed
Systems Management (DSM) architecture. SCF can be used to change the
characteristics of communications lines, devices, and subdevices for most
communications products without having to take your NonStop system down.
Subsystem Control Point (SCP). The management process for certain communications
subsystems.
Subsystem Programmatic Interface (SPI). A set of procedures for building and decoding
commands, responses, and event messages.
SYSGENR. A utility program used by DSM/SCM to generate a Tandem NonStop
Series/RISC (TNS/R) operating-system image for a given hardware and software
configuration on Tandem RISC systems.
Systems Network Architecture (SNA). The prevalent IBM communications model.
table. A logical representation of data in a database in which a set of records is represented as
a sequence of rows, and the set of fields common to all the records is represented as a
series of columns. As a NonStop SQL/MP object, a table represents data in columns
and specifies the physical characteristics of the table for the file system.
TACL. See Tandem Advanced Command Language (TACL).
TACL macro. A sequence of Tandem Advanced Command Language (TACL) commands
and built-in functions that can contain dummy arguments, thus providing a means for
simple argument substitution. When the macro name is given to TACL, TACL
substitutes the command sequences for the macro name and replaces any dummy
arguments with parameter values supplied to TACL. Macros are used to automate
operations tasks.
Tandem Advanced Command Language (TACL). A powerful, extended command
interpreter for the Tandem NonStop Kernel operating system that enables you to perform
work on NonStop systems.
