First, the dataset is not visible outside the report execution: for example, it cannot be directly reused by other reports. Second, an internal dataset is always defined as a SQL query and it cannot take advantage of Knowage business model abstraction.

For these reasons, Knowage allows the definition of external datasets in reports. An external dataset is defined in Knowage Server and, as a consequence, it is visible to all documents on the server i. External datasets can either be SQL datasets or QbE datasets, that is, datasets defined by queries over a business model. We always start by right-clicking on the Data Source item. Select Knowage Server Data Source and set the appropriate input configuration:.

After filling in the configuration fields, test the connection and save it. The new data source will appear in the left tree menu. Instead of connecting to a database via a JDBC driver, connect to the server as the source of data. Obviously, the actual data source and dataset must have previously been defined on the Server.

To select the dataset, click on New Data Set as above, but this time select the Knowage Data Source that you have just defined. Now, instead of choosing a new name for the dataset, insert the correct label of the dataset that you want to import from the Server.

If the label is correct, the dataset will be imported in the report by clicking on Finish. Since both types of datasets are stored in the same repository by Knowage Server, we are enabled to use any BM query in the development of a report. Most times reports show data analysis that depend on variable parameters, such as time, place, type.

Knowage Studio allows the designer to add parameters to a report and link them to analytical drivers defined in Knowage Server. To use these parameters, you first need to add them to your report. Right-click on Report Parameters in the tree panel and select New Parameter. Here you can set the data type and choose a name for your parameter. Once you have defined all parameters, open the or create a new dataset.

Parameters are identified by a question mark? For each? Note that you must set a link for each question mark as shown below, even if the same parameter occurs multiple times in the same query. Parameters can also be used within some graphical elements, such as dynamic text, with the following syntax:. To modify an already deployed document, first download the related template from the Knowage Server repository. Right-click on the Business Analysis folder or on one of its subfolders.

In the contextual menu, select the Download option. At this point, the functionality tree appears, allowing you to choose the documents to be downloaded.

These documents will be available in the local folder that you have previously selected. Document details i. To open Properties, right-click on the document item and select Properties.

In a similar way, after a document update, the Deploy option of the same menu sends the new template to the Server, ready for use. Another possible situation is when the designer creates a new template from scratch and deploys it on the Server. At first deploy, a link between the template and a document on the Server is created. It will last until the document on the Server is deleted or its label is modified. In those cases, you will need to re-deploy the template from the Studio.

To deploy a template, right-click and select Deploy. You will be prompted a form for basic metadata on the new document. However, they usually include:. These document details are stored as metadata in the local repository and used to register it in the central repository of the Server as well. Open topic with navigation. With BIRT, you take data from the database and produce a compound business report.

Besides the data themselves, your BIRT reports can be populated with such elements as images, tables, charts, etc. Viewed 2k times. Can anyone guide me how to do that? Improve this question. Add a comment. Active Oldest Votes.
