Program Dataset

Application Scenarios

You may need to use custom types of data sources for data analysis and dashboard display.

Functions

You can establish a remote connection between FineBI and FineReport to use customized data sources, like program dataset, which allows the FineBI engine to read the defined data sources for data analysis and dashboard creation.

Note:

Program data is now extracted in a streaming manner, which allows extracting billions of data records.

This document takes the built-in template execution log of FineBI as an example.

Defining Data Source

Click to download the template execution log file: ExecuteLog.zip

Click to download the platform management log file: OperateLog.zip

1. Copy the ExecuteLog.class file under the path %FineBI%/webapps/webroot/WEB-INF/classes/com/fr/log, and the program data source is defined successfully.

The codes of the template execution log file can be compiled into a class file.

package com.fr.log;

import com.fr.data.AbstractTableData;
import com.fr.decision.log.ExecuteMessage;
import com.fr.general.data.TableDataException;

import com.fr.third.springframework.util.CollectionUtils;

import java.util.ArrayList;
import java.util.List;

Establishing a Remote Connection

You need to remotely connect the designer to the FineBI server. For details, see FineReport Designer Connected to FineBI Project Remotely.

1. Open the designer and choose Server > Server Dataset.

2. Go to the server dataset interface and choose + > Class.

3. Click Select, select the added ExecuteLog.class file, and click OK to save.

4. You can see the added program dataset Class1 in Server Dataset.

Note:

To add multiple datasets, you can follow the above steps to add the OperateLog.class file.

 Adding a Program Data Table in FineBI

1. Log in to FineBI as the admin, click Public Data, select any folder, and choose Add Dataset > Database Table.

2. In Server Dataset, you can see the Class1 dataset added in the designer. Select the Class1 dataset and click OK to add it to the business package for use.
