Introducing Liquid Data
This topic provides a high level overview of the BEA Liquid Data for WebLogicTM product. It contains the following sections:
What is BEA Liquid Data for WebLogic?
BEA Liquid Data for WebLogic is a data access and aggregation product for Information Visibility, allowing a real-time unified view of disparate enterprise data. Information visibility is essential to enable greater supply-chain visibility, a unified view of customer information, and better decision-making.
BEA Liquid Data for WebLogic provides a cost effective, standard way to rapidly aggregate and expose logical views from any number of heterogeneous sources (including Web services, databases, flat files, XML files, applications and Web sites). This enables developers to re-use information across applications without dealing with the complexity of the underlying data.
One of the greatest challenges for IT organizations is that today's technologies do not adequately address the complexity inherent in aggregating data from distributed systems. BEA Liquid Data for WebLogic allows IT departments to easily aggregate data, in real time, from many sources within and outside of the enterprise, and tailor it for different business users, providing information visibility anywhere in the enterprise.
BEA Liquid Data for WebLogic is an easy-to-use product that simplifies the development of applications and portals that require aggregated, real-time information from disparate or heterogeneous sources. BEA Liquid Data for WebLogic returns results in XML for easy consumption by Web applications.
BEA Liquid Data for WebLogic delivers flexible, reusable information without the high cost and time consuming custom coding of queries and data transformations required with other products and solutions. Developers access BEA Liquid Data for WebLogic as simple Business Information Services created and published by a company's domain or data architects. Additionally, developers have the power and flexibility of XQuery, a standard SQL-like query language represented in XML, to directly access the distributed data sources, which are represented as integrated logical views.
BEA Liquid Data for WebLogic builds on existing IT infrastructure and leverages XML standards and BEA WebLogic® PlatformTM—the industry-leading application infrastructure—for easy and secure deployment in existing IT environments. BEA Liquid Data for WebLogic can be deployed as a standalone solution or within the framework of a larger project.
Liquid Data Capabilities

Liquid Data Roles and Responsibilities
This section describes the roles, responsibilities, and resources for the following types of Liquid Data users:
Each type of user has different tasks and tools for using the Liquid Data technology.
Data Architects
Data Architects know about the desired business entities to be created and the data sources that are required. Data Architects tend to be subject matter experts and have a deep understanding of the data, underlying schema, and relationships across the various data sources. They create the data views and stored queries used by the Application Developers, using either the Data View Builder tool or creating hand-coded XQuery queries. For more information, see Building Queries and Data Views.
Application Developers
Application Developers create applications that use the data views and stored queries, created by the Data Architects, to access real-time information. Application Developers can access data views and stored queries using the following mechanisms:
Application Developers can also write custom functions in Java code to extend Liquid Data functionality.
For more information, see Invoking Queries Programmatically.
System Administrators
System Administrators install, deploy, configure, and maintain the Liquid Data server. In addition to standard WebLogic Server administration tasks, an administrator uses the Liquid Data node in the Administration Console to perform the following kinds of tasks:
For more information, see the Liquid Data Administration Guide and Deploying Liquid Data.
