What’s new in 2.1


Entity Management

Derived attributes

Datanect now allows you to create derived attributes.
Derived attributes are be defined in the entity repository’s
specific query language. For now only RDBMS repositories are
supported. You can specify them e.g. in SQL.

Derived attributes in user-defined references

Derived attributes can also be used as source or target
attributes in user-defined entity references. This extends your
options when connecting data.

Datanect perspective

Type search for entity classes

You can open the type search dialog for entity classes
find and open entity classes more quickly. The selected entity
class will be opened in the tablebrowser.


Full quallified entity class name

The tablebrowser shows you the full qualified entity class
as the tab’s tool tip now.


User-defined attributes

User-defined attributes can be created through the
tablebrowser’s context menu

Comma-separated values for integer filters

The tablebrowser’s attribute filters allow comma-separated
list for integer types.

Full quallified entity class name

The tablebrowser shows you the full qualified entity class
as the tab’s tool tip now.

Invert selection

You can now invert the actual selection in the
tablebrowser through the context menu.

Sort columns

You can now sort the tablebrowser’s column. The sort will
only be applied to the tablebrowser’s actual content. It will
not be applied to the remote repository. E.g. by using an order
by SQL. This feature is planned for a later release.

Bug fixes
  • [DATANECT-221] – Selection takes a long time for large
    entity sets.

Bug fixes
  • [DATANECT-200] – CHAR based entity attributes are cut to 1 char

Entity Repository Explorer

User-defined markers

The Entity Repository Explorer shows an user-defined marker on entity
classes that either contains user-defined references or derived

Manage derived attributes

You can now add or remove derived attributes through the
Entity Repository Explorer’s context menu.

Manage user-defined references

You can also add or remove user-defined references through
the Entity Repository Explorer’s context menu.

Other resources

The Entity Repository Explorer now shows all other
resources that you create under the Datanect project. This gives
you a more flexible way to work with Datanect projcts.

Bug fixes
  • [DATANECT-201] – Support for LUW DB


Bug fixes
  • [DATANECT-217] – Cyclic dependencies should be ignored
    if they are not contained in the export entity set.

What’s new in 2.0

Datanect 2.0 is a nearly complete new implementation based on Eclipse RCP. The goal is to provide a more stable application, more familiar user interface and better IDE integration in the future.


Datanect is now based upon the eclipse rich client platform. The old databrowser is integrated through a separate frame and a read-only view now.

Entity Repository Explorer

The entity repository explorer provides you access to all entity repositories and contained entities

Dynamic POJO Mapping generation

You can generate a hibernate dynamic pojo mapping from every RDBMS based entity repository now. This very helpful for rapid prototyp creation.

The context menu of the tablebrowser provides you all available commands.


A new tablebrowser was added that is now used to browse the data.

The context menu of the tablebrowser provides you all available commands.


The outline gives you a structured overview over the opened tablebrowsers.



A treebrowser was added that allows you to support an entity related browsing. It is also very useful when you want to browse hierachical structures. Such as references to entities in the same table. E.g. child – parent relationships.


The export is completely re-implemented and now supports consistent export data sets. it shows you inconsistent entities and provides you actions to add required entities or remove inconsistent ones.


Open in default editor
When an export is finished it will ask you if the exported file should be opened in the default editor.
This editor can be changed using Preferences -> General -> Editors -> File Associations.


What’s new in 1.3.1


License management

You can now directly open the license management dialog from a notification window. This will help you to install a new license more quickly.

What’s new in 1.3.0


Proxy settings

Support for network proxies was added in 1.3.0. The proxy settings will be used by nearly any component within datanect. The only exception is the driver browser, because it will be configured usind the maven settings file. So if you have network problems, e.g. when you want to activate your license, you should check the proxy settings first and try again.


Entity repository manager

Driver browser settings

You can now change the maven settings xml path that the driver browser uses.


Quick search support

You can now search the entity repository manager using the quick search support, either by pressing CTRL-F or just start typing. Navigate through the search hits using the arrow up and down keys or tab.


Entity browser desktop

Metadata browsing

You can now browse the metadata of an entity repository as well. This will give you a better overview of how your data is connected. It’s a useful feature even if you use another tool, e.g. an SQL based database tool, because you will need the metadata information to create e.g. SQL queries.


Self associations

The entity explorer does now allows self associations. This is an important feature when you need to browse data that is hierarchical connected.

Filters allow whitespaces

You can add more than one value to an entity filter by separating the values with spaces now. This will work for all number types like short, integer, double, BigDecimal, etc.

Bug fixes

What’s new in 1.2.0

Entity repository manager

More well known drivers added to driver browser

JDTS driver added to the driver browser.

Entity browser desktop

Inter-repository browsing

You can now create instant associations between different data sources. This feature is helpful in distributed environments, e.g. in a microservice architecture. But it is also helpful when you want to connect data between different development stages, e.g. local developer database -> functional test database or integration database. See Help -> Help Contents -> Inter-Repository Browsing for details.

Association tool tips

Associations will show you a tool tips when you put the mouse cursor over them.

Datanect vision

You might already read the “What’s new in ….” or “Planned for ….” blogs that are about specific versions.

The Datanect vision, or roadmap, blog is about the middle and long term goals that I want to achieve with datanct.

Primary goal

Datanect should be a data analysis tool that is gives you a fast and clear data insight.


 Secondary goal

Datanect should support you in data export, import and migration.


Based on this goals the priority of tasks, user stories, etc. will be defined. But this doesn’t mean that secondary goal tasks are deferred until all primary goal tasks are done. It means that primary goal tasks will take most of the development power. Secondary goal tasks will take the rest, e.g. a 3/4 distribution.

The main principle of software development at Link Intersystems GmbH is to

build stable and reliable software

Therefore bugs always have a higher priority then new features.

The priority of bugs is determined by

  • impact on goals
  • affected users

This means that bugs that have a big impact on a primary goal will be highly prioritized even if only a few users are affected. On the other hand bugs that don’t have a big impact but affect a lot of users are also highly prioritized.

That’s why you should not hesitate to send me a bug mail so that I can better prioritize bugs.

You can use the contact form on the home page.

Planned for 1.2.0

Planned version changed from 1.0.2 to 1.2.0, because of 2 reasons:

  1. The version should have been changed to 1.1.0 with the previous release, because the tabbed browsing was a great improvement for the user experience.
  2. The inter-repository browsing feature will introduce a sophisticated data analysis between different data sources. It is extremely helpfull in microservices architectures and is therefore another great improvement that increases the options of data browsing.
