Release Notes 5.10

New Features

Variation functionality

In highly loaded applications performance of execution is a crucial point in development. There are many approaches to speed up your application. One of them is to calculate rules with variations. A variation means “additional calculation of the same rule with a slight modification in its arguments”. Variations are very useful when you need to calculate a rule several times with similar arguments. The idea of this approach is to once calculate rules for particular arguments and then recalculate only the rules or steps that depend on the modified (by variation) fields in those arguments.

In OpenL Tablets Business Analyst can increase performance of rules recalculation for variations by setting specified properties in the Rules table which allow: to switch on/off using cache while recalculating the table; to define the way of recalculation explicitly (recalculate always, never or analyzing the Rules table logic).

Dynamic Interface Support

OpenL Tablets Web Services application supports interface generation for services at runtime. If static interface isn’t defined for a service, the system generates it for you. The system uses an algorithm that generates interface with all methods defined in the module (or, in case of multimodule, in the list of modules).

WebStudio Installation Wizard

Implemented WebStudio Installation wizard which helps user to launch WebStudio and guide through the setup process for the first time. While installing, user have possibility: to define: a working directory; to select user mode as Single-user or Multi-user; to choose which Database to use for managing users in the application.
