BExIS 2.7.0

With this release again a number of new features, improvements and bug fixes have been implemented. Among them are the following:

Data Attributes and Variables can now have constraints. For example, a user may specify a range of accepted values (e.g. 0 – 100) or a list of valid terms for a given Variable.

Units can now contain a dimension specification (e.g. Length, Mass, Time) which provides a formal description for unit conversion.

Variables can have individual units of the same dimension (e.g. mm, cm, m, km) independent from their corresponding Data Attribute. Thus reusing Data Attributes is more flexible now.

Another new feature is available for dataset maintenance allowing data managers to check versions of a dataset and to virtually or physically remove datasets from the system. This feature is part of the new System Adminstration Module, which also contains the former Security Module.

In order to improve usability the system now features an Online Help for each module that is accessible within the application.

Besides those new features the performance has been improved in some parts, e.g. when viewing large primary data.
