Glossary-2
definition
definition. A dictionary object that describes a data structure, including the name, data
type, size, and other attributes of a field (elementary item) or of a named group of
fields.
ENABLE™. A product that is part of the ENCOMPASS Distributed Database Management
System. ENABLE allows you to build simple applications that execute within a
PATHWAY system.
Enform Plus. A language and a report generator used to retrieve information from
databases. Enform Plus can use DDL to define data format.
Enscribe. The HP database record manager, which provides access to and manipulation of
records in disk files.
explicitly parallel instruction set computing (EPIC). A processor architecture in which
the instruction stream encodes what can be done in parallel (so that the hardware
need not do this). Compare to complex instruction set computing (CISC) and reduced
instruction set computing (RISC).
extensible structured token. An SPI token to which new fields can be added.
File Utility Program (FUP). A HP product for creating files and altering file attributes.
host language. Generally, a programming language available on HP NonStop systems; in
this manual, a language in which the DDL compiler can generate source code.
locale. In localization, the definition of the subset of a user’s environment that depends on
language and cultural conventions.
Pathmaker. A NonStop Transaction Services/MP (NonStop TS/MP) application systems
generator that can create and manipulate a dictionary.
record. A dictionary object that describes the structure of an Enscribe disk file; a record
usually includes file creation information so that FUP can create a file from the record
structure. If the file is to be key sequenced, a record also contains the key attributes.
reduced instruction set computing (RISC). A processor architecture based on a relatively
small and simple instruction set, a large number of general-purpose registers, and an
optimized instruction pipeline that supports high-performance instruction execution.
Compare to complex instruction set computing (CISC)
and explicitly parallel instruction
set computing (EPIC).
simple token. An SPI token that has a single field or a fixed data structure.
source code. Input to a language compiler or other HP product.
schema. A set of DDL statements that define DDL objects.
schema file. An EDIT file that contains a schema.
