|Oracle® Enterprise Data Quality for Product Data Oracle DataLens Server Installation Guide
Part Number E23613-03
Oracle DataLens Server is built on industry-leading DataLens™ Technology to standardize, match, enrich, and correct product data from different sources and systems. The core DataLens Technology uses patented semantic technology designed from the ground up to tackle the extreme variability typical of product data.
Oracle Enterprise Data Quality for Product Data, formerly Oracle Product Data Quality, uses three core DataLens Technology modules: Governance Studio, Knowledge Studio, and Application Studio. The following figure illustrates the process flow of these modules.
The Enterprise DQ for Product (EDQP) Oracle DataLens Server can be configured to run with multiple servers:
Oracle DataLens Administration Server
Oracle DataLens Transform Server
The administration of all servers in a multi-server configuration is controlled with the Oracle DataLens Administration Server. The purpose of the Administration Server is to manage the various administrative tasks of the servers for the Server Groups (referred to as Transform Servers) and can itself serve as its own Transform Server when installed alone in a single node configuration. By spreading the data processing load across multiple servers the Oracle DataLens Server system provides scalability and configuration control over the various functional areas involved in developing, testing, and ultimately executing Oracle data lens jobs.
The type of Oracle DataLens Server Group that a Transform Server belongs to controls the individual server functionality. A Server Group may contain one or many physical servers. There are three types of Server Groups:
Development Server Group
Production Server Group
Quality Assurance Server Group
The Server Groups contain individual Oracle DataLens Transform Servers on physical machines that can load balance among servers within the group. The data lenses and DataLens Service Applications (DSAs) are deployed from one group to the next beginning with the development group, then migrating to the Quality Assurance Group for testing before arriving in the Production Group for deployment to production. This multiple group migration function facilitates an enterprise business process where multiple functional areas work on data lens objects in stages before releasing them to production.
The following sections describe the types of Oracle DataLens Servers.
An Oracle DataLens Administration Server is used to:
create and maintain users, and roles and responsibilities,
configure servers, connections, and Web services,
manage jobs, and
manage the creation, maintenance, and testing of data lenses, and DSAs.
Knowledge Studio users connect to this server for archiving and versioning, locking for update, and sharing data lenses and DSAs with other Knowledge Studio users. Only one Oracle DataLens Administration Server is allowed per deployment.
An Oracle DataLens Transform Server is used for running jobs and for deploying data lenses and DSAs in a production environment. They are also used for development and testing. Transform Servers do not have administrative privileges.
The Oracle DataLens Server topology consists of two components: the Administration Server and one or more Transform Servers that reside in one or more Server Groups.
The Oracle DataLens Server loads all data lenses into memory that have been flagged as loaded in the
ServerProfiles configuration file. This file should never need to be edited manually; it can be modified using the Oracle DataLens Server Administration Web pages.
