is the alfresco activiti part of the alfresco ECM solution, in other words, if i install the ECM solution , can i design processes without the need to install activiti on its own ?
<q>unfortunately, the mix of company, product and library names can be quite confusing to figure out if you are not already familiar with them.
Alfresco - the name of the company and often / for historical reasons also used as the name of the primary ECM product, which is available as Alfresco Community (open source) and Alfresco One (commercial) Activiti - the name of the BPM open source library that is both embedded into the Alfresco ECM product (Alfresco Community and Alfresco One), but also exists as a separate, commercial product called "Alfresco Activiti"
So your question might be if you need Alfresco Community / One which has Activiti embedded, or Alfresco Activiti, which is Activiti without any document management, but provides a lot of corporate-level business process management features that Alfresco Community / One do not have. E.g. allowing business users to design, model and activate business processes in the live instance, adding process analytics etc.</q>
Short form: If you install the ECM solution, you cannot design processes in the live instance without installing Alfresco Activiti too. You can however design & develop processes using modelling tools in IDEs, such as Eclipse, and activate those dynamically, but it won't be anything like shown in <a href="https://www.youtube.com/watch?v=pQ9E1qOoIp8">this demo</a>.
