Data Workbench 6.5 Release Notes
Data Workbench 6.5 release notes include new features, upgrade requirements, fixed bugs, and known issues.
New Features
Data Workbench 6.5 includes these new features:
The Association Tableand Association Chordvisualizations let you associate metrics with metrics, dimensions, and dimension elements using the Cramer's V algorithm. The Associations Table and Chord compares values using the Cramer's V calculation rather than using Pearson's correlation coefficient as employed in the Correlation Matrixand Correlation Chordvisualizations (these can only compare metrics, while the Association Table and Chord can compare metrics, dimensions, and elements).
To open, select Visualization > Predictive Analytics > Association Table or Association Chord from the workspace.
Evaluate a Decision Tree using the Regression Tree optionby right-clicking and selecting Options > Regression Tree within a Decision Tree visualization.
Updated Decision Tree builder: The new algorithm was introduced for building a Decision Tree. It handles more general data and provides a more informative visualization to improve the precision of the prediction.
Improved data sampling module: An updated adaptive sampling scheme helps Decision Tree and Propensity Score achieve higher precision results.
- Type Ctrl > O in a workspace to open a visualization (.vw) file. It is the same as selecting Add > Open from the toolbar.
- Type Ctrl > E in a workspace to edit a configuration file by default, or browse to open other file types.
The Open files feature now lists the most current files and files you want "pinned" to the menu for quick access. Right-click and select Open from menu in a workspace, or select Add > Open and Add > Edit from the toolbar.
Attention: Click the pin icon next to the item to save the workspace in the menu.
New easy-to-understand descriptions of the applied filters will now display in these visualizations and editors:
- Filter Editor (when you hover over the title)
- Filter panel on the Finder
- Propensity Score visualization
- Cluster Builder visualization
- Decision Tree Builder visualization
An SFTP/FTP exportwas added to the Export Integration framework. You can now configure settings from the client (workstation) and export using CSV, TSV, Segment Export, or Segment Export with Header using FTP and SFTP protocols, allowing you to send files to servers.
Select any of the exports by right-clicking on a Detail Table. Once selected, an export configuration table opens allowing you to add or update export settings.
Upgrade Requirements
Follow these requirements and recommendations when upgrading to Data Workbench 6.5.
- Changes in the
Components for Processing Servers\Communications.cfg
file require you to update this file for the DWB 6.5 release. The SourceListServer, SegmentExportServer, and NormalizeServer entries were removed. (DPU’s should not be running sourcelist, segment export, or normalize servers. )
System Updates
These features have been renamed, deleted, or the installation files or folders were restructured in this release:
-
Correlation Chord, Correlation Matrix, Association Chord, Association Matrix, Propensity Score, and Best Fit Attribution visualizations are now multi-pass visualizations, allowing them to run in Report Server.
note important IMPORTANT You can only have one multi-pass visualization in a workspace. When there are more than one multi-pass visualizations in a workspace, Report Server will fail to generate reports by default and throw the following error: code language-none Too many Multipass visualizations in workspace ....... (has #, 1 allowed).
Avoid this error by updating your ReportServer.cfg file or add this line to your existing file in the Reporting section. > code language-none Max Multipass Per Slice = int: 1
The Max Multipass Per Slice value must remain set at 1 (See Known Issues). -
Changes made to files in the Server\Menu\Admin folder.
- Removed Lookups.
- Added Archive Files and User Files.
- Modified Files, Export Files, Log Files.
Updated files include:
code language-none Base\Menu\Admin\Order.txt (changes to menu)
code language-none Base\Menu\Admin\Files.vw (removed Lookups and Events string, added Archive and Users strings)
code language-none Base\Menu\Admin\Archive Files.vw
code language-none Base\Menu\Admin\User Files.vw
-
Changes made to files in the Base\Context\ServerDetails folder:
code language-none Base\Context\ServerDetails\Archive Files.vw
code language-none Base\Context\ServerDetails\Export Files.vw
code language-none Base\Context\ServerDetails\Log Files.vw
code language-none Base\Context\ServerDetails\User Files.vw
code language-none Base\Context\serverdetails\files.vw
code language-none Base\workspaces\admin\dataset and profile\server files.vw
-
Changes made to the self-administration of member access.
A new file in the Base and Server packages includes a User List.cfg for Admins to update for member access.
Fixed Bugs
The following are prominent fixes made in Data Workbench 6.5 (since the release of Data Workbench 6.4).
- Fixed block decoding bug that was introduced in release 6.4. Issue was encountered during processing of a very large visitor.
- Fixed alignment bug introduced with compiler upgrade. Issue affected Replication in release 6.4
Known Issues
- Use of the Windows Certificate Store is limited to the English only (no Chinese or Japanese language support).
- Regression Analysis on graphs does not recognize new workspace selections. A possible workaround is to redo the regression after making a new selection.
- The Max Multipass Per Slice value must remain set at 1. You cannot have more than one of the following visualizations in a single workspace intended for Report Server: Propensity Score, Best Fit Attribution, Association Matrix, Association Chord, Correlation Matrix, or Correlation Chord.
