Data Transformation in Flow.BI

The ability for Flow.BI reports to manipulate data to change its order or structure before display.

Sorting Data Source Records

Using the built-in functionality of a data source to order records during retrieval, often accomplished using SQL's ORDER BY clause.

Sorting Data in the Report

Utilizing the 'Sort' property in the Properties window of a data band to specify the order of records based on selected fields.

Data Transformations for Sorting

Creating dedicated data transformations to achieve complex sorting logic. These can be used for various scenarios, including custom sorting algorithms.

Study Notes

Ordering Records in Flow.BI

  • Reporting engines frequently reorder records after initial retrieval, making ORDER BY in the data source insufficient for guaranteed order.
  • Data transformations are crucial for reliable record ordering. Flow.BI Reports offers flexible data transformation capabilities for ordering records.

Methods for Ordering Records

  • Sorting Data Source Records:
    • SQL Data Sources: Directly order records using the ORDER BY clause in your SQL query. Example: SELECT * FROM Orders ORDER BY OrderDate DESC.
    • Other Data Sources: Utilize built-in sorting capabilities, or implement sorting logic within the source's query/retrieval method.
  • Sorting Data in the Report (Using Sort Property):
    • Select the data band needing sorting.
    • In the Properties window, set the Sort property to a comma-separated list of expressions. Example: Sort = "OrderDate DESC, ProductName ASC" (first by OrderDate descending, then ProductName ascending).
  • Using Data Transformations:
    • Create a new data transformation by right-clicking the data source in the Data Dictionary and selecting "New Data Transformation."
    • Configure the transformation to match your desired ordering.
    • Set the data band's DataSource property to the transformed data source.

Additional Considerations

  • Complex Sorting: Employ multiple levels of sorting or custom algorithms for complex scenarios.
  • Custom Sorting: Create custom data sources or transformations for specialized sorting needs.
  • Testing & Debugging: Rigorously test the sorting logic to confirm accuracy. Thoroughly test your sorting logic.
  • Performance Optimization: Optimize data source queries and transformations for large datasets. Consider optimizing data source queries and transformations for large datasets to improve performance.
