Configure a data feed

You can configure a data feed in the data feed editor. Here you can define the structure and logical flow of a data feed using graphical elements, such as data source operators or data transformation operators.

Procedure

  1. Open the data feed editor. An empty data feed opens. By default, the Data sources panel provides quick access to a selection of operators and data sources, such as ARIS documents. Data feed editor

  2. Click Show all to display all supported data sources and operators. The panel for selecting an operator opens.

    Select operator

  3. Select a data source operator in the Select operator panel, for example, the XML data source operator.

    Every operator added to the data feed is placed in a stream.

    The data source operator is added to the data feed in Stream 1, which is automatically connected to the Output operator. By default, the stream names are numbered, for example, Stream 1, Stream 2.

    New stream

  4. Click the data source operator within the stream to specify the data source settings.

    The selected operator is marked and the corresponding configuration panel is displayed, for example, Configure XML operator.

    Make your settings. Most options are already described in the help of the data source operators.

    In the following example, a URL refers to an XML file. The recurring element and the columns are automatically detected.

    Data source settings

  5. You can add more operators to a data steam. A stream can contain one data source operator and several transformation operators that are processed one after the other. Click + add operator under the selected operator and select the operator to be added in the Select operator panel.

    The operators provided in the Select operator panel depend on the operators already used in the selected stream. To display all available operators, click Show all in the Select operator panel.

    For example, you can change the data type and filter the rows according to certain criteria.

    Extended stream

  6. You can add more streams to the data feed. Each stream forms a structural or logical unit for processing data.

    Click the data feed background and select the operators as described above.

    For example, you can add another data source or a new stream with operators.

    More streams

  7. You can drag and drop operators within and between streams. A suitable place within a stream is indicated by a green placeholder line.

    Move operator

  8. You can remove an operator from a stream and drag and drop it as a separate stream.

    Replace operator

  9. You can connect streams of the same type. That is, you can connect streams that return tables (teal) with each other or you can connect streams that return single values (yellow).

    Move the mouse pointer over the docking point of a stream, hold down the mouse button, drag a connection to the docking point of the target stream, and release the mouse button.

    Connect streams

  10. You can connect an operator to a stream of type Single value to use it as data input. Note that not all operators allow single values as input.

    1. Select an operator within a stream of the Table type, for example, the Filter rows operator. The corresponding configuration panel is displayed.

    2. Select the stream you want to connect. For example, specify the filter condition for the Filter rows operator.

      1. In the configuration panel, click the Add Add icon in the left condition box and select the column to be filtered, for example, Country.

      2. Click the operator icon and select an operator. By default, the Operator equals operator is used.

      3. Click the Add Add icon in the right condition box and select the source whose values are used for filtering. In this case, click Select a stream and select a stream, for example, Stream 4.

        Select stream

        The Filter rows operator is connected to the selected Stream 4 as data input.

        Connection

  11. Analogous to step 9, you can specify different data inputs for operators, for example, user inputs, columns, or constant values.

  12. Click the Save icon -> Save Save.

  13. Enter a feed name and click Save.

You have configured a data feed.

You can use the data feed as a data source for a dashboard.
