Liquid Data Quick Start
The following sections guide you through all the tasks required to design and implement a real-time data access and aggregation solution using BEA Liquid Data for WebLogicTM. This topic is meant to provide a high-level view of the process. To read more detail about any particular task, follow the links provided to the document where that topic is discussed in full detail.
For a walkthrough of steps 3, 4, and 5, see Getting Started With Liquid Data
Step 1. Install the Software
To use Liquid Data, you begin by installing the WebLogic Platform and the Liquid Data software according to the instructions in Installing Liquid Data
Step 2: Explore the Liquid Data Samples
After you install the software, you can run the one-time samples configuration, launch the samples server, and then explore Liquid Data using the Liquid Data samples. For more information, see Running the Samples
Step 3. Define the Data Access and Aggregation Requirements and Scope
Before you can create queries, you need to clarify the requirements and scope of your data access and aggregation solution, answering such questions as:
Step 4. Configure Access to Data Sources
Before you can create queries, you must configure access to the data sources that provide these queries with the required content. You use the Liquid Data node in the Administration Console to configure access to data sources, via data source descriptions, as described in the following topics in the Liquid Data Administration Guide:
Certain data source types, such as relational databases and application views, require additional configuration tasks that are also described in their respective sections. You might also need to perform other configuration tasks described elsewhere in the Liquid Data Administration Guide.
Step 5. Create XQuery Queries
Once you have configured access to data sources, you can create XQuery queries to retrieve the information needed for your data access and aggregation solution. You can either use the Data View Builder to generate the XQuery for you (based on a design you construct using its graphical tools), or you can hand code the XQuery. Either way, you use the Data View Builder to save queries as stored queries in the Liquid Data server repository. For more information, see Building Queries and Data Views.
Step 6: Invoke Queries Programmatically (Optional)
Client applications can invoke Liquid Data queries in the following ways:
For more information, see Invoking Queries Programmatically.
Step 7. Create the Presentation Layer
In Liquid Data the presentation layer is the software component that handles the layout, formatting, and display of query results to users. Liquid Data provides a JSP (Java Server Pages) tag library that you can use to create the presentation layer in JSP pages. The Liquid Data Tag Library can be used with both stored queries and ad hoc queries. For more information, see Creating the Presentation Layer.
Step 8. Deploy the Data Access and Aggregation Solution
After you have created all the components of your data access and aggregation solution, you need to deploy it in a production environment. In addition to defining deployment requirements and designing the deployment, you need to deploy the Liquid Data Server, the server repository, and other resources in a WebLogic domain in a production environment. For more information, see Deploying Liquid Data.
