This glossary defines terms for Oracle Business Intelligence Enterprise Edition. See also the Oracle Fusion Middleware Master Glossary for additional terms and definitions.
action
Provides functionality to navigate to related content or to invoke operations, functions or processes in external systems. You can include actions in analyses, dashboard pages, agents, scorecard objectives, scorecard initiatives, and KPIs.
See also action link.
Action Framework
The Action Framework is a component of the Oracle BI EE architecture and includes a J2EE application called the Action Execution Service (AES) and actions-specific JavaScript functionality deployed as part of Oracle BI EE. The action framework also includes client-side functionality for creating actions and invoking certain action types directly from the browser.
action link
A link to an action that you have embedded in an analysis, dashboard page, scorecard objective, scorecard initiative, or KPI that, when clicked, runs an associated action.
See also action.
ADF Business Intelligence Component
Provides the developer the ability to include Oracle Business Intelligence catalog objects in ADF Applications. This component uses a SOAP connection to access the Oracle BI Presentation Catalog.
Admin Server
Is part of the WebLogic domain, and runs the processes that manage Oracle Business Intelligence components. The Admin Server contains the Oracle WebLogic Server Administration Console, and Fusion Middleware Control.
See also Fusion Middleware Control and Managed Server.
agent
Enables you to automate your business processes. You can use them to provide event-driven alerting, scheduled content publishing, and conditional event-driven action execution.
Agents can dynamically detect information-based problems and opportunities, determine the appropriate individuals to notify, and deliver information to them through a wide range of devices (e-mail, phones, and so on).
aggregate persistence
A feature that automates the creation and loading of aggregate tables and their corresponding Oracle Business Intelligence metadata mappings to enable aggregate navigation.
aggregate table
A table that stores precomputed results from measures that have been aggregated over a set of dimensional attributes. Each aggregate table column contains data at a given set of levels. For example, a monthly sales table might contain a precomputed sum of the revenue for each product in each store during each month. Using aggregate tables optimizes performance.
aggregation rule
In an Oracle BI repository, a rule applied to a logical column or physical cube column that specifies a particular aggregation function to be applied to the column data, such as SUM
.
In Presentation Services, users can see the rules that have been applied in the repository. Users can also change the default aggregation rules for measure columns.
alias table
A physical table that references a different physical table as its source. Alias tables can be used to set up multiple tables, each with different keys, names, or joins, when a single physical table needs to serve in different roles. Because alias table names are included in physical SQL queries, you can also use alias tables to provide meaningful table names, making the SQL statements easier to read.
analysis
A query that a user creates on the Criteria tab in Presentation Services. An analysis can optionally contain one or more filters or selection steps to restrict the results.
See also filter and selection step.
analysis criteria
Consists of the columns, filters, and selection steps that you specify for an analysis.
See also analysis.
analysis prompt
A prompt that is added to an analysis. When the user selects a prompt value, that value then determines the content that displays in the analysis containing the prompt, only.
See dashboard prompt and prompt.
attribute
The details of a dimension in an Oracle BI repository. Attributes usually appear as columns of a dimension table.
attribute column
In Presentation Services, a column that holds a flat list of values that are also known as members. No hierarchical relationship exists between these members, as is the case for members of a hierarchical column. Examples include ProductID or City.
See hierarchical column.
BI domain
Contains configurable System components (the coreapplication) and Java components (the WebLogic domain), and also includes the Web-based management tools and applications that utilize resources.
A BI domain can be a set of middleware homes spread across one or more physical servers.
See also BI instance.
BI object
A piece of business intelligence content that is created with Presentation Services and saved to the Oracle BI Presentation Catalog. Examples of BI objects include analyses, dashboards, dashboard pages, scorecards, and KPIs.
BI Search
A search tool that resides outside of Presentation Services. BI Search is available from the Home Page after the Administrator adds a link to the BI Search URL. BI Search provides a mechanism for searching for objects in the Oracle BI Presentation Catalog that is similar to a full-text search engine.
bookmark link
Captures the path to a dashboard page and all aspects of the page state.
See prompted link.
bridge table
A table that enables you to resolve many-to-many relationships between two other tables.
business model
Contains the business model definitions and the mappings from logical to physical tables. Business models are always dimensional, unlike objects in the Physical layer, which reflect the organization of the data sources. Each business model contains logical tables, columns, and joins.
Business Model and Mapping layer
A layer of the Oracle BI repository that defines the business, or logical, model of the data and specifies the mapping between the business model and the Physical layer schemas. This layer can contain one or more business models.
The Business Model and Mapping layer determines the analytic behavior that is seen by users, and defines the superset of objects available to users. It also hides the complexity of the source data models.
business owner
The person responsible for managing and improving the business value and performance of a KPI or scorecard object, such as an objective, cause and effect map, and so on.
cause & effect map
A component of a scorecard that lets you illustrate the cause and effect relationships of an objective.
See also Oracle Scorecard and Strategy Management.
chronological key
A column in a time dimension that identifies the chronological order of the members within a dimension level. The key must be unique at its level.
Cluster Controller
A process that serves as the first point of contact for new requests from Presentation Services and other clients. The Cluster Controller determines which Oracle BI Server in the cluster to direct the request to based on Oracle BI Server availability and load. It monitors the operation of servers in the cluster, including the Oracle BI Scheduler instances. The Cluster Controller is deployed in active-passive configuration.
column
In an Oracle BI repository, columns can be physical columns, logical columns, or presentation columns.
In Presentation Services, indicates the pieces of data that an analysis will return. Together with filters and selection steps, columns determine what analyses will contain. Columns also have names that indicate the types of information that they contain, such as Account and Contact.
See also analysis, attribute column, hierarchical column, and measure column.
column prompt
A type of filter that allows you to build specific value prompts on a data column to either stand alone on the dashboard or analysis or to expand or refine existing dashboard and analysis filters.
See also prompt.
complex join
A join in the Physical layer of an Oracle BI repository that uses an expression other than equals.
condition
Objects that return a single Boolean value based on the evaluation of an analysis or of a key performance indicator (KPI). You use conditions to determine whether agents deliver their content and execute their actions, whether actions links are displayed in dashboard pages, or whether sections and their content are displayed in dashboard pages.
See also action, action link, agent and key performance indicator (KPI).
connection pool
An object in the Physical layer of an Oracle BI repository that contains the connection information for a data source.
See also Physical layer.
content designer
The user who creates business intelligence objects such as analyses, dashboards, and scorecards.
contextual event action
A pre-delivered action that utilizes the Action Framework to pass content from the business intelligence object to another region on an ADF page.
See also action, Action Framework, and action link.
cube
An OLAP (online analytical processing) data structure that lets data be analyzed more quickly and with greater flexibility than structures in relational databases. Cubes are made up of measures and organized by dimensions. Cubes in multidimensional data sources roughly correspond to star schemas in relational database models.
currency prompt
A prompt that allow the user to change the currency type that displays in the currency columns on an analysis or dashboard.
See also prompt.
custom view
A component of a scorecard that lets you show a customized view of your business and strategy data.
See also Oracle Scorecard and Strategy Management.
dashboard
An object that provides personalized views of corporate and external information. A dashboard consists of one or more pages. Pages can display anything that you can access or open with a Web browser, such as results of analyses, images, alerts from agents, and so on.
dashboard prompt
A prompt that is added to the dashboard. When the user selects a prompt value, that value then determines the content that will display in all analyses included on the dashboard.
See analysis prompt and prompt.
Dashboard URL
Used for incorporating or referencing the content of a specific dashboard in external portals or applications. It has a number of forms and optional arguments that can be used to control its behavior.
data source name (DSN)
A data structure that contains the information about a specific database, typically used by an ODBC driver to connect to the database. The DSN contains information such as the name, directory, and driver of the database.
Connection pool objects in the Physical layer of the Oracle BI repository contain DSN information for individual data sources.
database hint
Instructions placed within a SQL statement that tell the database query optimizer the most efficient way to execute the statement. Hints override the optimizer's execution plan, so you can use hints to improve performance by forcing the optimizer to use a more efficient plan. Hints are only supported for Oracle Database data sources.
dimension
A hierarchical organization of logical columns (attributes). One or more logical dimension tables may be associated with at most one dimension.
A dimension may contain one or more (unnamed) hierarchies. There are two types of logical dimensions: dimensions with level-based hierarchies (structure hierarchies), and dimensions with parent-child hierarchies (value hierarchies).
A particular type of level-based dimension, called a time dimension, provides special functionality for modeling time series data.
See also hierarchy.
dimension table
A logical table that contains columns used by a particular dimension. A dimension table cannot be a fact table.
See also fact table.
driving table
A mechanism used to optimize the manner in which the Oracle BI Server processes multi-database joins when one table is very small (the driving table) and the other table is very large.
event polling table
Event polling tables (also called event tables) provide information to the Oracle BI Server about which physical tables have been updated. They are used to keep the query cache up-to-date. The Oracle BI Server cache system polls the event table, extracts the physical table information from the rows, and purges stale cache entries that reference those physical tables.
Essbase
A multidimensional database management system available from Oracle that provides a multidimensional database platform upon which to build business intelligence applications. Also referred to as Oracle's Hyperion Essbase.
fact table
In an Oracle BI repository, a logical table in the Business Model and Mapping layer that contains measures and has complex join relationships with dimension tables.
See also dimension table.
filter
Criteria that are applied to attribute and measure columns to limit the results that are displayed when an analysis is run. For measure columns, filters are applied before the query is aggregated and affect the query and thus the resulting values.
See also prompt and selection step.
foreign key
A column or a set of columns in one table that references the primary key columns in another table.
fragmentation content
The portion, or fragment, of the set of data specified in a logical table source when the logical table source does not contain the entire set of data at a given level. Fragmentation content is defined by the logical columns that are entered in the Fragmentation content box in the Content tab of the Logical Table Source dialog box.
Fusion Middleware Control
Provides Web-based management tools that enable you to monitor and configure Fusion Middleware components.
global header
An Oracle BI Presentation Services user interface object that contains links and options that allow the user to quickly begin a task or locate a specific object within the Presentation Catalog. The global header always displays in the Presentation Services user interface, thus allowing users to quickly access links and search the catalog without having to navigate to the Home Page or Catalog page.
Go URL
Used to incorporate specific business intelligence results into external portals or applications. The Go URL is used when you add a result to your favorites or add a link to a request to your dashboard or external Web site. It has a number of forms and optional arguments that can be used to control its behavior.
hierarchical column
In Presentation Services, a column that holds data values that are organized using both named levels and parent-child relationships. This column is displayed using a tree-like structure. Individual members are shown in an outline manner, with lower-level members rolling into higher-level members. For example, a specific day belongs to a particular month, which in turn is within a particular year. Examples include Time or Geography.
See also attribute column.
hierarchy
In an Oracle BI repository, a system of levels in a logical dimension that are related to each other by one-to-many relationships. All hierarchies must have a common leaf level and a common root (all) level.
Hierarchies are not modeled as separate objects in the metadata. Instead, they are an implicit part of dimension objects.
See also dimension, logical level, and presentation hierarchy.
hierarchy level
In Presentation Services, an object within a hierarchical column that either rolls up or is rolled up from other levels. Corresponds to a presentation level in an Oracle BI repository.
See also presentation level.
home page
Provides an intuitive, task-based entry way into the functionality of Presentation Services. The Home page is divided into sections that allow you to quickly begin specific tasks, locate an object, or access technical documentation.
image prompt
A prompt that provides an image with different areas mapped to specific values. The user clicks an image area to select the prompt value that populates the analysis or dashboard.
See also prompt.
initialization block
Used to initialize dynamic repository variables, system session variables, and nonsystem session variables. An initialization block contains the SQL statements that will be executed to initialize or refresh the variables associated with that block.
initiative
Used in a scorecard, an initiative is a time-specific task or project that is necessary to achieve objectives. As such, you can use initiatives that support objectives as milestones as they reflect progress toward strategy targets.
See also objective and Oracle Scorecard and Strategy Management.
Java components
Fusion Middleware Control components that are deployed as one or more Java EE applications (and a set of resources) and are managed by Node Manager.
See also Node Manager.
key performance indicator (KPI)
A measurement that defines and tracks specific business goals and strategic objectives. KPIs often times roll up into larger organizational strategies that require monitoring, improvement, and evaluation. KPIs have measurable values that usually vary with time, have targets to determine a score and performance status, include dimensions to allow for more precise analysis, and can be compared over time for trending purposes and to identify performance patterns.
See also Oracle Scorecard and Strategy Management.
KPI watchlist
A method of distributing KPIs to end users. A watchlist is a collection of KPIs that are built by adding the KPIs stored in the catalog. After a KPI watchlist is built and saved, it is stored as a catalog object and can be added to dashboards and scorecards.
See also key performance indicator (KPI).
logical display folder
Folders used to organize objects in the Business Model and Mapping layer. They have no metadata meaning.
logical join
Joins that express relationships between logical tables. Logical joins are conceptual, rather than physical, joins. In other words, they do not join to particular keys or columns. A single logical join can correspond to many possible physical joins.
logical level
In an Oracle BI repository, a component of a level-based hierarchy that either rolls up or is rolled up from other levels.
Parent-child hierarchies have implicit, inter-member levels between ancestors and descendants that are not exposed as logical level objects in the metadata. Although parent-child hierarchies also contain logical level objects, these levels are system generated and exist to enable aggregation across all members only.
Logical SQL
The SQL statements that are understood by the Oracle BI Server. The Oracle BI Server Logical SQL includes standard SQL, plus special functions (SQL extensions) like AGO
, TODATE
, EVALUATE
, and others.
Clients like Presentation Services send Logical SQL to the Oracle BI Server when a user makes a request. In addition, Logical SQL is used in the Business Model and Mapping layer to enable heterogeneous database access and portability. The Oracle BI Server transforms Logical SQL into physical SQL that can be understood by source databases.
logical table
A table object in the Business Model and Mapping layer of an Oracle BI repository. A single logical table can map to one or more physical tables. Logical tables can be either fact tables or dimension tables.
See also dimension table and fact table.
logical table source
Objects in the Business Model and Mapping layer of an Oracle BI repository that define the mappings from a single logical table to one or more physical tables. The physical to logical mapping can also be used to specify transformations that occur between the Physical layer and the Business Model and Mapping layer, as well as to enable aggregate navigation and fragmentation.
Managed Server
An individual J2EE application container (JMX MBean container). It provides local management functions on individual hosts for Java components and System components contained within the local middleware home, and refers to the Admin Server for all of its configuration and deployment information.
See also Admin Server and Fusion Middleware Control.
measure column
A column that can change for each record and can be added up or aggregated in some way. Typical measures are sales dollars and quantity ordered. Measures are calculated from data sources at query time.
Measure columns are displayed in the Oracle BI repository, usually in fact tables, or in Presentation Services.
metadata
Data about data. Metadata objects include the descriptions of schemas (such as tables, columns, data types, primary keys, foreign keys, and so on) and logical constructs (like fact tables, dimensions, and logical table source mappings).
The Oracle BI repository is made up of the metadata used by the Oracle BI Server to process queries.
metadata dictionary
A static set of XML documents that describe metadata objects, such as a column, including its properties and relationships with other metadata objects. A metadata dictionary can help users obtain more information about metrics or attributes for repository objects.
mission statement
A statement in a scorecard that specifies the key business goals and priorities that are required to achieve your vision.
See also Oracle Scorecard and Strategy Management and vision statement.
multi-database join
A join between two tables in an Oracle BI repository, where each table resides in a different database.
Node Manager
A daemon process that provides remote server start, stop, and restart capabilities when Java processes become unresponsive or terminate unexpectedly.
See also Java components.

Work that is performed on data when moving from a database to another location (sometimes another database). Some transformations are typically performed on data when it is moved from a transaction system to a data warehouse system.
unbalanced hierarchy
A hierarchy where the leaves do not have the same depth. For example, an organization may choose to have data for the current month at the day level, data for the previous at the month level, and data for the previous five years at the quarter level.
See also hierarchy.
variable
Objects in an Oracle BI repository that are used to streamline administrative tasks and dynamically modify metadata content to adjust to a changing data environment.
Variables are of the following types:
Repository variables have a single value at any point in time. There are two types of repository variables: static and dynamic.
Session variables are created and assigned a value when each user logs on. There are two types of session variables: system and nonsystem.
variable prompt
Allows the user to select a value specified in the variable prompt to display on the dashboard. A variable prompt is not dependent upon column data, but allows you to manipulate, for example add or multiply, the column data on an analysis.
See also prompt.
virtual physical table
A physical table that is made from a stored procedure or a SELECT
statement. Creating virtual tables can provide the Oracle BI Server and the underlying databases with the proper metadata to perform some advanced query requests.
