Referential Integrity Error Handling (Release 4.1.15)

Referential Integrity Error Handling (Release 4.1.15)

VaultSpeed release 4.1.15 just went live! Here’s what’s new...

Referential Integrity

When integrating multiple source systems into one data vault, you might encounter some issues with referential integrity. This can have numerous reasons like issues with source batch processing, late data arrival, source mismatches or the possibility of early arriving data.

In any case it will cause you some headaches to fix these kind of problems. With VaultSpeed, you now have an extra set of tools to tackle these problems.

In the latest release we added referential integrity error handling logic. We added two new parameters: REFERENTIAL_INTEGRITY_VALIDATED and REFERENTIAL_INTEGRITY_FORCE_LINK_LOAD.

What happens when you activate the first parameter? VaultSpeed will store records in an error table if it cannot find the referenced key. These records will not be inserted in the link tables. Not loaded unless you activate forced link loading, it that case the tool will add a reference to the ‘unknown’ record.

In addition VaultSpeed will add error table records when processing subsequent loads. This allows us to check whether the reference can be resolved with new data available.

Other Changes

  • You can now create a self reference relationship which contains an attribute that references itself i.e. (c,b) → (a,b). You can do this by right clicking the attribute while in relation creation mode.

  • We added the ability to update and save multiple records at the same time to the following screens: Source objects & attributes, DV name management, DV data types screens, Business vault views.
New Save buttons
  • You can now revert SAT splits.
  • We added subscription info to the dashboard. You can also see the actual number of concurrent users.

  • You can now switch the ODI_FOLDER_SPLIT parameter after having already deployed the project (for customers using Oracle Data Integrator).

SAT split editor improvements

Our developers also made some improvements to the SAT-split editors based upon customer feedback (we added a new SAT-split screen in a previous release):

    • We now have an option to change the number of visible attributes in a split (just click the button with 3 vertical dots and go to settings).
    • We added an option to sort the attributes in descending order in the context menu.
    • The editor now has the option to show only unused attributes to the context menu.
    • You can now remove attributes from a split or add them to another split by dragging and dropping.
    • Long table names are now displayed correctly.
    • Improved handling of multiple splits.
    • The split name will no longer disappear when you scroll down the attribute list of a split.

Stay tuned for more release news!

Data Lineage Export (Release 4.1.14)

Data Lineage Export (Release 4.1.14)

In the upcoming release, we incorporated some important improvements. First, we added a first version of our data lineage export functionality. Second, we added support for higher customization of DDL Options. We also added an alternative screen to handle satellite splitting. And finally, after introducing a lot of new objects in the business vault, we added business vault loading to our Flow Management solution in Apache Airflow.

At VaultSpeed, we invest a lot of time analyzing customer feedback and enhancement requests. At regular points in time, we try to align this feedback with our product roadmap in order to stay in line with customers needs.

Data Lineage Export

With VaultSpeed we gather source metadata. This metadata can be enhanced, maintained and fine-tuned by users. In the end we use all this metadata to generate a valid Data Vault 2.0 model. With this in mind, we have all necessary information to provide customers with proper data lineage. It is now possible to export this information to a CSV format.

Exported Data lineage in csv format

Starting at the Data Vault overview screen, users will see 2 new buttons. The first button is for object level data lineage, the second one you can use for attribute level lineage. When you click these buttons a CSV file concerning the entire data vaults object or attribute lineage will be downloaded trough your browser.

This is the first iteration of data lineage functionality in VaultSpeed, we are looking at alternative export formats and integrations with popular data lineage tools and possibly also some data lineage views inside VaultSpeed.

DDL Options for each table type

Using VaultSpeed, you were already able to define certain DDL settings. With these settings, you can create optional DDL layouts for the tables that will be created throughout all layers of your data warehouse. For example you are able to define a certain level of parallelism, or set a specific partitioning type or other, depending on the specificities of your target database.

We now made it possible to create these DDL settings at table type level. So you could for example create a different setting for a HUB compared to a satellite.

Enhanced SAT split screen

Our UX designers try to improve VaultSpeed's look and feel continuously. They came up with a different layout for our satellite splitting screen. This version should work a lot better when you are splitting tables into more than 2 sattelite splits. Also, it is now possible to show multiple satellites in one canvas. Finally, it is more aligned with other graphical screens in the tool. So users should recognise the menu's from other screens.

New SAT-split screen

All previous functionalities are still available in this screen. The old screen is still present for user that prefer to work in the old one. We will analyze customer feedback as to which screen gets the best reviews.

Business Vault loading added to FMC

The FMC module or Flow Management Center is our Apache Airflow based solution to orchestrate flows. This module can be purchased in addition to a standard licence. It offers a solution for customers that additionally require an orchestration tool. In recent releases, we added a lot of new functionality in the Business Vault layer. This new logic can now also be loaded using our FMC module. VaultSpeed will generate Airflow DAGs for loading of PITs, Bridges and Cross source links. Read more about FMC on our features page.

Cross Source Links (Release 4.1.12/13)

With release 4.1.12 and 4.1.13 we brought some interesting new features.

First of all, we included support for cross source exploration links. The main idea behind building an enterprise wide data warehouse is to be able to integrate data from multiple sources. This requirement is now delivered out of the box in VaultSpeed.

Vaultspeed already provided HUB Groups to integrate between sources at business key level. With our new Cross Source Link objects, you can create links between multiple sources. This adds an additional way to integrate and explore between sources.

In the source graphical editor an option has been added to select entities from other sources and their specific releases. By selecting and adding the object to the canvas, a relationship can be defined between objects from different sources. Notice that foreign objects will be shown in a different color and that the source name is mentioned in the object name.

Import object from another source and add a relationship

Once the object and the relationship have been added, new data vault and business vault releases can be generated. The resulting relationship will add a link object between both sources.

New link is added to the data vault model

We integrate cross source link objects at the Business Vault level. There are several reasons why this is the best place for the integration:

First of all, cross source links create dependencies between sources, we do not want inter source dependencies between sources in the raw data vault because it would complicate the loading process.

Second, we have to make sure that all the data has arrived in the raw data vault to process our cross source links. With data coming in from different sources at different times, there might be issues with “missing links”. VaultSpeed takes care of this issue.

Finally, by placing the cross source link in the business vault layer, we make it less dependent from underlying source changes. This facilitates version management and release management of these structures.

Also included in this release is a new type of delete logic, INSERT_ON_DELETE: when this parameter is enabled, deletes will insert a new record in the satellite instead of executing an update, these delete records will be end dated just like regular records. This parameter has no effect when using INSERT_ONLY_LOGIC.

We also improved performance and look and feel for the source graphical editor. The objects will now also be displayed in a tree like structure to give a better overview of the source.

More new stuff coming soon!

Bridge tables (Release 4.1.11)

The start of a new year welcomes a new release. VaultSpeed kicked of 2020 with some brand new features in version 4.1.11. We added support for bridge tables in a new graphical editor and added the possibility to import and export business names in the business vault. By adding bridge tables, VaultSpeed now supports the 5 main objects in data vault 2.0: Hubs, Links and Satellites in the Raw Data Vault. But also PITs and Bridges in the Business Data Vault. The graphical bridge editor enables users to generate bridge tables based upon raw data vault objects. All available Hubs can be dragged and dropped to the editor.



Once a certain hub is selected on the canvas, the adjacent hub tab becomes active. It contains all adjacent hubs for the selected hub. Each adjacent hub can be dragged into the editor. Hubs can have multiple links to the same adjacent hub. It is not possible to add more than one link connection for a starting / ending hub.



The Bridges tab contains all available bridges. It is possible to remove, edit or create a bridge. To edit a bridge, first load it by dragging it into the editor, then you can start modifying it. To save the changes, click the edit button which is above bridge list in order to complete the edit. To create a new bridge, build it in the editor and click the create new bridge button. Creating a new bridge and editing a bridge is only possible when the bridge combination is valid, otherwise a warning message will be displayed.




It is possible to let the app generate possible paths between two hubs. To do this, Right click and select draw shortest path relation, then drag a line between the 2 hubs you want to connect. Then you can change the number of possible paths it will generate by setting “max generation options”, as well as excluding hubs from the paths. If there is only one viable option, then it will be directly applied to the editor. However, if there is more than one option, then an extra tab becomes active and it is possible to preview, regenerate or apply options to the paths. To preview or regenerate a path, you need to selected a bridge and click one of the buttons above the shortest path options list. During preview editor becomes read-only. To apply the selected shortest path option while in preview mode, click the apply button, otherwise you can drag and drop the desired path option into the editor.
