Glossary

access service

The named set of properties, used with a DirectConnect Access Service Library, to which clients connect. Each DirectConnect Server can have multiple services.

access service library

A component of DirectConnect. A service library that provides access to non-Sybase data contained in a database management system or other type of repository. Each such repository is called a “target.” Each access service library interacts with exactly one target and is named accordingly. See also service library.

Adaptive Server (formerly SQL Server)

The server in the Sybase Client-Server architecture. It manages multiple databases and multiple users, tracks the actual location of data on disks, maintains mapping of logical data description to physical data storage, and maintains data and procedure caches in memory. Also called Adaptive Server Enterprise.

Any reference to Adaptive Server applies to SQL Server version 10.5 or earlier, unless otherwise specified.

administrative service library (ADMLIB)

A service library that provides remote management capabilities and server-side support. It supports a number of remote procedures (invoked as RPC requests) that enable remote DirectConnect management. See also remote procedure call, service library.

application program interface (API)

A functional interface, supplied by an operating system or other licensed program, that allows an application program written in a high-level language to use specific data, functions of the operating system, or the licensed program.

ASE/CIS

The CIS component of Adaptive Server Enterprise (ASE), formerly called OmniConnect. See also Adaptive Server.

bulk copy transfer

A transfer method in which multiple rows of data are inserted into a table in the target database. See also transfer. Compare with destination-template transfer.

catalog stored procedure

A stored procedure that provides information about tables, columns, and authorizations. It is used in SQL generation and application development.

character set

A set of specific (usually standardized) characters with an encoding scheme that uniquely defines each character. ASCII is a common character set.

Client-Library

A library of routines that is part of the Sybase Open Client product. See also Open Client.

client/server

An architecture in which the client is an application that handles the user interface and local data manipulation functions, while the server provides data processing access and management for multiple clients. See also client, server, client application.

collection

An AS/400 library that contains views of AS/400 global catalog tables and journals.

code page

An assignment of graphic characters and control function meanings to all code points.

connection

A network between two systems. For SNA, the path connects an LU on one machine to an LU on another machine. For TCP/IP, the path connects TCP modules on separate machines.

CSP

See catalog stored procedure.

CT-Library

See Client-Library.

database management system (DBMS)

A computer-based system for defining, creating, manipulating, controlling, managing, and using databases.

DB-Library

A Sybase and Microsoft API that allows client applications to interact with ODS applications.

destination-template transfer

A transfer method in which source data is briefly put into a template where the user can specify that some action be performed on it before execution against a target database. See also transfer. Compare with bulk copy transfer.

DirectConnect

A Sybase Open Server application that provides access management for non-Sybase databases, copy management, and remote systems management. Each DirectConnect consists of a server and one or more service libraries to provide access to a specific data source. DirectConnect replaces the MDI Database Gateway and OmniSQL Access Module. Compare with Enterprise Connect.

DirectConnect Manager

A Sybase Windows application that provides remote management capabilities for DirectConnect products. These capabilities include starting, stopping, creating, and copying services. Formerly called DirectConnect Configuration Tool.

DirectConnect Server

The component that provides general management and support functions (such as log file management) to service libraries.

DirectConnect Service

The named set of properties, used with a DirectConnect Service Library, to which clients connect. Each DirectConnect can have multiple services.

DirectConnect Service Library

The component that provides a set of functions within the DirectConnect Server environment.

dynamic link library (dll)

A file containing executable code and data bound to a program at load time or run time, rather than during linking. The code and data in a dynamic link library can be shared by several applications simultaneously.

Enterprise Connect

The encompassing architecture upon which Sybase implements heterogeneous data integration. Compare with DirectConnect.

environment variable

A variable that describes how an operating system runs and the devices it recognizes.

graphical user interface (GUI)

A type of computer interface consisting of a visual metaphor of a real-world scene, often of a desktop. Within that scene are icons, representing actual objects, that the user can access and manipulate with a pointing device.

GUI

See graphical user interface.

host

The mainframe or other machine on which a database, an application, or a program resides. In TCP/IP, this is any system that is associated with at least one Internet address. See also Transmission Control Protocol/Internet Protocol.

interfaces file

An operating system file that determines how the host client software connects to a Sybase product. The file must be available on each machine that connects to DirectConnect or other Sybase products.

library

A named disk area that can contain programs and related information. A library consists of different sections, called library members.

libtcl file

A file containing a list of installed Net-Library drivers. Client applications use information in this file and the sql.ini file to connect to Adaptive Servers (formerly known as SQL server) or Open Server applications. See also sql.ini.

license host

Primary server on which the SySAM lmgrd and SYBASE daemons reside.

localization

The process of preparing an extracted module for a target environment, in which messages are displayed and logged in the user’s language; numbers, money, dates, and time are represented using the user’s cultural convention; and documents are displayed in the user’s language. See also globalization. Compare with internationalization.

ODBC

See Open Database Connectivity.

Open Client

A Sybase product that provides customer applications, third-party products, and other Sybase products with the interfaces required to communicate with Open Client and Open Server applications.

Open Server

A Sybase product that provides the tools and interfaces required to create a custom server.

remote license host

Remote machine or server on which SySAM license files and daemons reside.

remote procedure call (RPC)

A stored procedure executed on a different DirectConnect Server from the one onto which a user is logged or on which the initiating application resides.

RPC

See remote procedure call.

server

A functional unit that provides shared services to workstations over a network. See also client/server. Compare with client.

service

A functionality available to DirectConnect applications. It is the pairing of a service library and a set of specific configuration properties.

service library

A set of configuration properties that determine service functionality. Examples of service libraries include access service libraries, administrative service libraries, and transaction router service libraries. See also access service library, administrative service library, Transaction Router Service library, transfer service library.

service name redirection

A type of service name resolution that allows a system administrator to map alternative connections to services. See also service name resolution. Compare with direct resolution.

service name redirection file

The default name of the file used for the service name redirection feature. See also service name redirection.

SNRF

See service name redirection file.

sql.ini

The interfaces file containing definitions for each DirectConnect Server to which a workstation can connect. The file must be on every client machine that connects to Adaptive Servers. See also interfaces file, libtcl file.

system administrator

The user in charge of server system administration. For DirectConnect, the user responsible for installing and maintaining servers and service libraries.

TCP/IP

See Transmission Control Protocol/Internet Protocol.

transfer

A DirectConnect feature that allows users to move data or copies of data from one database to another. See also bulk copy transfer, destination-template transfer.
