Message: [QUOTE="Tim Ferguson, post: 2563994"] I am sure that this would make sense when cast into some formal kind of analysis. There are Activities, and there are Processes, and they are related in some way. There are presumably different TypesOfProcesses, and maybe even BigProcesses and SelectProcesses and IncompleteProcesses suitable for a subtyping model. The thought of "embedding a table within a value" brings back all those horrid 60's and 70's designs like network databases, where you had to know the data before being able to write the access paths. The whole point of SQL and R theory is that you are _guaranteed_ to be able to reach the information you want armed only with the schema. Best wishes Tim F [/QUOTE]
