Glossary

alert

an automatic notification of an electronic event that is of interest to the recipient.

authentication

See client authentication

authentication domain

a SAS internal category that pairs logins with the servers for which they are valid. For example, an Oracle server and the SAS copies of Oracle credentials might all be classified as belonging to an OracleAuth authentication domain.

authentication provider

a software component that is used for identifying and authenticating users. For example, an LDAP server or the host operating system can provide authentication.

base path

the location, relative to a WebDAV server's URL, in which packages are published and files are stored.

client authentication

the process of verifying the identity of a person or process for security purposes.

client-side pooling

a configuration in which the client application maintains a collection of reusable workspace server processes.

content mapping

the correspondence of the SAS metadata folder structure to a content repository system. SAS metadata folders are generally mapped to a WebDAV such as the SAS Content Server repository, or to a local file system.

credentials

the user ID and password for an account that exists in some authentication provider.

deploy

to install an instance of operational SAS software and related components. The deployment process often includes configuration and testing as well.

foundation repository

the metadata repository that is used to specify metadata for global resources that can be shared by other repositories. For example, a foundation repository is used to store metadata that defines users and groups on the metadata server.

foundation services

See SAS Foundation Services

hot deployment

the process of upgrading an application or component in a client-server environment while the server is running. Hot-deployed components are made available immediately, and do not require the server to be restarted.

identity

See metadata identity

Java Development Kit

See JDK

Java RMI

See remote method invocation

Java Virtual Machine

See JVM

JDK

a software development environment that is available from Oracle Corporation. The JDK includes a Java Runtime Environment (JRE), a compiler, a debugger, and other tools for developing Java applets and applications. Short form: JDK.

JVM

a program that interprets Java programming code so that the code can be executed by the operating system on a computer. The JVM can run on either the client or the server. The JVM is the main software component that makes Java programs portable across platforms. A JVM is included with JDKs and JREs from Oracle Corporation, as well as with most Web browsers. Short form: JVM.

metadata identity

a metadata object that represents an individual user or a group of users in a SAS metadata environment. Each individual and group that accesses secured resources on a SAS Metadata Server should have a unique metadata identity within that server.

middle tier

in a SAS business intelligence system, the architectural layer in which Web applications and related services execute. The middle tier receives user requests, applies business logic and business rules, interacts with processing servers and data servers, and returns information to users.

pool

a group of server connections that can be shared and reused by multiple client applications. A client-side pool consists of one or more puddles.

portal

a Web application that enables users to access Web sites, data, documents, applications, and other digital content from a single, easily accessible user interface. A portal's personalization features enable each user to configure and organize the interface to meet individual or role-based needs.

portlet

a Web component that is managed by a Web application and that is aggregated with other portlets to form a page within the application. Portlets can process requests from the user and generate dynamic content.

puddle

a group of servers that are started and run using the same login credentials. Each puddle can also allow a group of clients to access the servers.

remote method invocation

a Java programming feature that provides for remote communication between programs by enabling an object that is running in one Java Virtual Machine (JVM) to invoke methods on an object that is running in another JVM, possibly on a different host. Short form: RMI.

remote service deployment

a service deployment that supports shared access to a set of SAS Foundation Services that are deployed within a single Java Virtual Machine (JVM), but which are available to other JVM processes. Applications use the remote service deployment to deploy and access remote foundation services.

repository

a storage location for data, metadata, or programs.

RMI

See remote method invocation

SAS Application Server

a logical entity that represents the SAS server tier, which in turn comprises servers that execute code for particular tasks and metadata objects.

SAS batch server

a SAS Application Server that is running in batch mode. In the SAS Open Metadata Architecture, the metadata for a SAS batch server specifies the network address of a SAS Workspace Server, as well as a SAS start command that will run jobs in batch mode on the SAS Workspace Server.

SAS BI Web service

a Web service that adheres to the XML for Analysis (XMLA) specification for executing SAS Stored Processes.

SAS Content Server

a server that stores digital content (such as documents, reports, and images) that is created and used by SAS client applications. To interact with the server, clients use WebDAV-based protocols for access, versioning, collaboration, security, and searching.

SAS Foundation Services

a set of core infrastructure services that programmers can use in developing distributed applications that are integrated with the SAS platform. These services provide basic underlying functions that are common to many applications. These functions include making client connections to SAS application servers, dynamic service discovery, user authentication, profile management, session context management, metadata and content repository access, activity logging, event management, information publishing, and stored process execution.

SAS Framework Data Server

a database server that is the default location for middle-tier data such as alerts, comments, and workflows, as well as data for the SAS Content Server and SAS Service Parts Optimization. The server is provided as an alternative to using a third-party DBMS. The server cannot be used as a general-purpose data store.

SAS Management Console

a Java application that provides a single user interface for performing SAS administrative tasks.

SAS Metadata Repository

a container for metadata that is managed by the SAS Metadata Server.

SAS Web Infrastructure Platform

a collection of middle-tier services and applications that provide infrastructure and integration features that are shared by SAS Web applications and other HTTP clients.

SAS Workspace Server

a SAS IOM server that is launched in order to fulfill client requests for IOM workspaces.

server-side pooling

a configuration in which a SAS object spawner maintains a collection of reusable workspace server processes that are available for clients. The usage of servers in this pool is governed by the authorization rules that are set on the servers in the SAS metadata.

service

one or more application components that an authorized user or application can call at any time to provide results that conform to a published specification. For example, network services transmit data or provide conversion of data in a network, database services provide for the storage and retrieval of data in a database, and Web services interact with each other on the World Wide Web.

service configuration

a set of values that can be customized for a particular service in SAS Foundation Services. By editing a service configuration, you can override the default configuration for the foundation service.

service deployment

a collection of SAS Foundation Services that specifies the data that is necessary in order to instantiate the services, as well as dependencies upon other services. Applications query a metadata source (a SAS Metadata Server or an XML file) to obtain the service deployment configuration in order to deploy and access foundation services.

session context

a context that serves as a control structure for maintaining state within a bound session. 'State' includes information about the latest status, condition, or content of a process or transaction. Session Services, User Services, and Logging Services use the session context to facilitate resource management and to pass information among services.

single sign-on

an authentication model that enables users to access a variety of computing resources without being repeatedly prompted for their user IDs and passwords. For example, single sign-on can enable a user to access SAS servers that run on different platforms without interactively providing the user's ID and password for each platform. Single sign-on can also enable someone who is using one application to launch other applications based on the authentication that was performed when the user initially logged on.

SSO

See single sign-on

theme

a collection of specifications (for example, colors, fonts, and font styles) and graphics that control the appearance of an application.

trust

to accept the authentication or verification that has been performed by another software component.

trust relationship

a logical association through which one component of an application accepts verification that has already been performed by another component.

trusted user

a privileged service account that can act on behalf of other users on a connection to the metadata server.

unrestricted identity

a user or group that has all capabilities and permissions in the metadata environment due to membership in the META: Unrestricted Users Role (or listing in the adminUsers.txt file with a preceding asterisk).

user context

a set of information about the user who is associated with an active session. The user context contains information such as the user's identity and profile.

Web-distributed authoring and versioning

a set of extensions to the HTTP protocol that enables users to collaboratively edit and manage files on remote Web servers. Short form: WebDAV.

WebDAV

See Web-distributed authoring and versioning

WebDAV repository

a collection of files that are stored on a Web server so that authorized users can access them.
