An application programming interface that provides Java language functions for handling messages. Java Runtime Environment. A subset of the Java Development Kit that allows you to run Java applets and applications. Key Performance Indicator (KPI). A specific value threshold of a business metricthat definesthe acceptable business performance level. Listener. In WebSphere MQ distributedqueuing, a program that detects incoming network requests and starts the associated channel. Master data. Data that remains unchanged over a long period of time. (attributes, texts, and hierarchies -- similar to data warehouse dimensions). Materialized Query Table. A table where the results of a query are stored, for later reuse. Measure. A data item that measures the performance or behavior of business processes. Message broker. A set of execution processes hosting one or more message flows. Message domain. The value that determines how the message is interpreted (parsed). Message flow. A directed graph that represents the set of activities performed on a message or event as it passes through a broker. A message flow consists of a set of message processing nodes and message processing connectors. Message parser. A program that interprets the bit stream of an incoming message and creates an internal representation of the message in a tree structure. A parser is also responsible to generate a bit stream for an outgoing message from the internal representation. Message processing node connector. An entity that connects the output terminal of one message processing node to the input terminal of another. Message processing node. A node in the message flow, representing a well-defined processing stage. A message processing node can be one of several primitive types or it can represent a subflow. Message Queue Interface. The programming interface provided by the WebSphere MQ queue managers. This programming interface allows application programs to access message queuing services. Message queuing. A communication technique that uses asynchronous messages for communication between software components. Message repository. A database that holds message template definitions. Message set. A grouping of related messages. Message type. The logical structure of the data within a message. Meta Data. Typically called data (or information) about data. It describes or defines data elements. Metrics (business). Measurements of business performance. MOLAP. Multi-dimensional OLAP. Can be called MD-OLAP. It is OLAP that uses a multi-dimensional database as the underlying data structure. MultiCube. A pre-joined view of twoormorecubes represented as an OLAP cube to the user. MQSeries. A previous name for WebSphere MQ. Multi-dimensional analysis. Analysis of data along several dimensions. For example, analyzing revenue by product, store, and date. 192 BPM Meets BI Nickname. An identifier that is used to reference the object located at the data source that you want to access. Node. A device connected to a network. Node Group. Group of one or more database partitions. ODS. Operational data store: A relational table for holding clean data to load into InfoCubes, and can support some query activity. OLAP. OnLine Analytical Processing. Multi-dimensional data analysis, performed in real-time. Not dependent on underlying data schema. Open Database Connectivity. A standard application programming interface for accessing data in both relational and non-relational database management systems. Using this API, database applications can access data stored in database management systems on a variety of computers even if each database management system uses a different data storage format and programming interface. ODBC is based on the call level interface (CLI) specification of the X/Open SQL Access Group. Open Hub. Enables distribution of data from an SAP BW system for external uses. Optimization. The capability to enable a process toexecute and perform in such a way as tomaximize performance, minimize resource utilization, and minimize the process execution response time delivered to the user. Output node. A message processing node that represents a point at which messages flow out of the message flow. Partition. Part of a database that consists of its own data, indexes, configuration files, and transaction logs. Pass-through. The act of passing the SQL for an operation directly to the data source without being changed by the federation server. Pivoting. Analysis operation where user takes a different viewpoint of the results. For example, by changing the way the dimensions are arranged. Plug-in node. An extension to the broker, written by a third-party developer, to provide a new message processing node or message parser in addition to those supplied with the product. Point-to-point. Style of application messaging in which the sending application knows the destination of the message. Predefined message. A message with a structure that is defined before the message is created or referenced. Process. An activity within or outside an SAP system with a defined start and end time. Process Variant. Name of the process. A process can have different variants. For example, in the loading process, the name of the InfoPackage represents the process variants. The user defines a process variant for the scheduling time. Primary Key. Field in a database table that is uniquely different for each record in the table. PSA. Persistent staging area: Flat files that hold extract data that has not yet been cleaned or transformed. Pushdown. The act of optimizing a data operation by pushing the SQL down to the lowest point in the federated architecture where that operation can be executed. More simply, a pushdown operation is one that is executed at a remote server. Queue Manager. A subsystem that provides queuing services to applications. It provides an application programming interface so that applications can access messages on the queues that are owned and managed by the queue manager. Glossary 193 Queue. A WebSphere MQ object. Applications can put messages on, and get messages from, a queue. A queue is owned and managed by a queue manager. A local queue is a type of queue that can contain a list of messages waiting to be processed. Other types of queues cannot contain messages but are used to point to other queues. RemoteCube. An InfoCube whose transaction data is managed externally rather than in SAP BW. ROLAP. Relational OLAP. Multi-dimensional analysis using a multi-dimensional view of relational data. A relational database is used as the underlying data structure. Roll-up. Iterative analysis, exploring facts at a higher level of summarization. Server. A device or computer that manages network resources, such as printers, files, databases, and network traffic. Shared nothing. A data management architecture where nothing is shared between processes. Each process has its own processor, memory, and disk space. Slice and Dice. Analysis across several dimensions and across many categories of data items. Typically to uncover business behavior and rules. SOAP. Defines a generic message format in XML. Static SQL. SQL that has been compiled prior to execution. Typically provides best performance. Subflow. A sequence of message processing nodes that can be included within a message flow. Subject Area. A logical grouping of data by categories, such as customers or items. Synchronous Messaging. A method of communication between programs in which a program places a message on a message queue and then waits for a reply before resuming its own processing. Thread. In WebSphere MQ, the lowest level of parallel execution available on an operating system platform. Type Mapping. The mapping of a specific data source type to a DB2 UDB data type. UDDI. A special Web service which allows users and applications to locate Web services. Unit of Work. A recoverable sequence of operations performed by an application between two points of consistency. User Mapping. An association made between the federated server user ID and password and the data source (to be accessed) user ID and password. Virtual Database. A federation of multiple heterogeneous relational databases. Warehouse Catalog. A subsystem that stores and manages all the system metadata. WebSphere MQ. A family of IBM licensed programs that provides message queuing services. Workbook. Microsoft Excel workbook with references to InfoProvider. Wrapper. The means by which a data federation engine interacts with heterogeneous sources of data. Wrappers take the SQL that the federation engine uses and maps it to the API of the data source to be accessed. For example, they take DB2 SQL and transform it to the language understood by the data source to be accessed. WSDL. Language to define specific SOAP messages interfaces understood by the Web services provider. XML. Defines a universalway of representingdata, and an XML schema defines the format. xtree. A query-tree tool that allows you to monitor the query plan execution of individual queries in a graphical environment. 194 BPM Meets BI Zero latency.
