Process definitions are stored on the process repository, as simple XML 
files, so not in the database.
Runtime state persistence for Drools Flow for process instances (one 
process instance = one row in this table) is something like this in its 
simplest form:

Table ProcessInstanceInfo
ProcessInstanceId    processId    startDate    lastReadDate   
lastModificationDate    state    processInstanceByteArray
