Development of Customized Workflow Engines

Customized Workflow Engines


Many software generally consists of some workflows. The workflow engine refers to a piece of software which is designed to follow the blueprint to execute a workflow. Basically, this means that person without knowing coding skills can make changes to working of the software and what features are available there. Of course, partially in this project developer wish to create first, the required micro-services and then they can be used. A workflow engine is basically a software which is designed to administer and monitor the finalisation of the stages in a workflow. The workflow engine can make decisions and also monitors the execution of stated tasks and if the task fails it can execute some actions to appropriate the situation or cancel next steps and report an error. Workflow engine generally uses the database to store information about workflows and steps in them.

Mostly workflow engines have some main functions:

  • Access control but only users with permission can execute tasks
  • Execute a task and complete if the execution succeeded, after execution act accordingly.
  • Checking that plan is valid for the task to be executed.

Generally, workflow engines consist of business rules engine which is a bit of software that pursues rules stated by something. In theory, the rules might be laws or regulations etc. However, generally in IT-world, the rules are stated by designing the process with some markup language, usually XML, which the business rules engine then follows and execute tasks stated in the composition. This permit changing and customizing the process without rebuilding the application. Sometimes it may also implement the user to change the process without having knowledge of programming.
