These points will be described in the following. At first execution of Knowage Studio, a welcome page appears. The first step is to create a Knowage project by selecting the Knowage icon of the following figure from the toolbar located at the top of the page. Once the project has been created, a standard folder tree appears. The predefined folders are: Business Analysis: it contains all developed documents reports, charts, cockpits, etc. This folder can be structured with subfolders, to freely organize ones own documents; Private folders: they contain the users personal or project documentation. This folder can be freely managed by the user; Resources: they contain all technical resources used in the project i.

This chapter offers ways to track bugs and defects that arise from testing. For example, if a data set contains a column for first name and another for last name, using the expression builder you can concatenate the values into one data element. Grid elements act as containers for other report elements and are used to position elements in a logical manner.

Grid elements are configured in tabular format. For example, if your report is displaying product sales and you want a chart representation to the right of your table data, you would add a grid element with one row and two columns.

List elements also act as containers for other elements. Lists differ from other container elements in that they iterate over data sets that are bound to the list. The default list element has a header, footer and detail section. When the list is rendered, the header and footer are usually displayed once, while the detail section is displayed for every row of the data set that is bound to the list. Within the detail section you may have a text element or another container element such as a grid, table or another list.

Table elements are similar to list in that they are container elements that iterate over bound data sets, but are represented in tabular format.

The table element layout is similar to an HTML table. Table elements have header, footer and detail sections as well as columns. Aggregation elements are new for BIRT 2.

Figure 9 - Aggregation element The chart element allows charts to be inserted into the report design. When a chart element is placed in the Report Editor, the Chart Builder Wizard automatically displays. Thirteen primary chart types and many combinations of sub-types are available with BIRT 2. The Chart Builder provides drag-and-drop functionality, live chart preview, data filtering, and parameterization.

In previous versions of BIRT, the number of columns in a table element had to be known at design-time, whereas with the cross tab element, the number of columns and rows can be dynamic. This element also supports hierarchal aggregation and display of data, allowing cube dimensions to be placed on rows and columns, and measuring data to be displayed at appropriate intersections. These libraries are referenced from reports that use them, meaning that changes in the library are automatically reflected in all reports that use the library.

A good example is using a report library to store the company logo.

If the company logo changes, only the library needs updating, not the reports that references it. Libraries are referenced relative to the resource folder which is configurable in the designer for design-time and in the web. Figure 12 - Library Explorer Property Editor The Property Editor View is used to set properties for report elements that have been added to the report.

The items displayed will be determined by what report element is selected in the Report Editor. The Properties window presents common settings, such as style, width, and font information. Additionally, most report elements support the visibility property that allows hiding content dynamically.

While most of these functions are self explanatory, the Map tab allow dynamic conditions to be built using the Expression Builder that dynamically change the display value of a report element.

For example, if your month row value is "1", you may want to display "January". The Highlights tab uses conditions to apply different style formats dynamically, such as showing low sales numbers in red. Most of these functions allow multiple conditions or keys to be placed on an item. One condition may change the color of the font, while another condition may change the font size. One sort key can list the results alphabetically, while another sort key puts "Jones" at the top of the list.

Figure 14 - Style Highlighting Outline The Outline View presents a graphical hierarchy of the report design and illustrates the report element to container relationship.

Report elements can be directly selected within the outline view and is very helpful when you have complex report designs. Additionally with BIRT 2. Password: the users password. Active: a flag that indicates the active server. It is particularly useful when the user is working with multiple servers.

The active server indicates that every upload and download operation refers to this Knowage Server instance. Warning Connection to Knowage Server If something in your network configuration has been changed from your first run of Knowage Studio, the connection test of Knowage Studio to the Server could fail.

Most often this problem is due to the proxy settings in your Eclipse environment. If this is not the case, try to run Knowage Studio from the command line with the clean option Knowage. At this point, Knowage Studio is ready to work! The most relevant technical metadata describing document structure, content and behaviour are: Template, which defines the document layout; Data set, which defines how data of each document should be read; Analytical drivers, which hook the template parameters to the graphical interface at runtime , managing also the right form for parameters.

Knowage Studio supports BI developers steering the implementation of the template for each analytical document through an easy graphical interface and simple wizards. Each document type has its own designer and manages the relation with data sources and data sets. Furthermore it enhances technical users with all the needed functionalities to design, develop, test, deploy and maintain Knowage analytical documents.

As said above, each document is mainly associated to a template describing its layout and a data set defining how data will fill it. Warning Datasets created with the Business Model These data sets are often based on specific business models created through Knowage Meta.

By the way, we will concentrate on how to manage the implementation of a data set using the BIRT Report designer available in Knowage We want to remark that an expert developer can work directly on the server, managing documents and data sets by hand, thanks to the web interface for administrators and developers. Usually, this procedure is faster when only small changes are required on already released documents, whereas the Studio is particularly useful when a developer works on new documents.

The target users of the Studio module are: BI developers, who define analytical documents and data sets to be released onto a remote Knowage Server administrators, who define or update analytical documents and data sets. In other words, Knowage Studio covers the development processes of more technical documents. On the other hand, high-level documents are created directly through Knowage Server, where a power user can access graphical designers without need to use the Studio, which requires more technical skills to manage the installation and configuration process.

In Figure below we will choose Report with Birt and leave the other option to the next chapter. Once the document is designed, it is stored as a local file, marked out with an icon and a specific file extension:. In our case, we will get a. A double click on one of these files allows to open the document template, with its related graphical editor.

The design and deployment of a BIRT report includes the following steps: create the empty document; switch to the report designer perspective; create the data source; design the report via the graphical interface; deploy the report on the server. This will open an editor where you can choose the name of your document.

The new document will be created under the Business Analysis folder. Double click on it to open the editor. At this point, you are still working in the Knowage perspective. To design the report, switch to the actual BIRT designer perspective. Click on the perspective icon of the Eclipse editor and select the Report Designer among the available perspectives, as showed in figure below. The next steps are the creation of a datasource and of a dataset.

As previously described in the section Dataset Definition, Knowage Studio allows the development of analytical documents using either internal or external datasets.


In this specific example, we will show how to create a report with an internal dataset. Right click on the Data Source item and select the corresponding data source. A pop up editor will open, prompting you the connection settings: Driver class Database URL Username and password Note that these configuration parameters will be used by the Studio to connect to the database and let the report to be executed locally i.

Make sure that the database set in the Server share the same schema of that defined in the Studio. Since you are setting a local reference to a database inside the report, remember to set an additional information: this will enable Knowage Server to correctly execute the report, by connecting to the data source referenced within the server and not inside the report.

Basically you need to tell the server to override the data source configuration.

Fill in the form as suggested below. Without these settings your BIRT report may be unable to access data once it is deployed on the server. In addition, if database and connection properties change, you need to change the connection properties only in Knowage server. Once the data source has been configured, you can proceed with the creation of a dataset. In the next window, select the data source, the type of query and give a name to the dataset, as exhibited below.

The scope of this name is limited to your report, because we are defining an internal dataset. Now you can define your dataset by writing the SQL query in the editor and testing the results see Fig. At any time, you can modify the dataset by clicking on it, which will re-open the query editor.
