Disclaimer for Jose: I'm one of Elixir authors. Simpler than Elixir? How so? If you are speaking about the internal guts, then you are right declarative is simpler (which is normal since it does less), but if you meant the usage (and I *think* it's what the original poster meant here), I have to disagree... Their simplicity is comparable, and I would even vote for Elixir as slightly simpler because of the little helper methods you get for free... If you meant "usage" here, please explain why you think so. > I'm using it (declarative) on > a production project and so are many others, and forms the basis of > the object-relational plugin for Grok.

Well, in my opinion, apart from the different syntax which is probably a matter of taste, the only real difference between Elixir and declarative is that Elixir can generate columns and tables for you, which makes development faster (and arguably simpler) when you are building the database from scratch as you develop your application. It allows to implement recurring (database) patterns without repeating yourself. Those pattern range from the simple "many-to-one" column, to the different inheritance patterns, via the table for a many-to-many relationship. On the other hand, if you are using a legacy database, Elixir doesn't offer any significant advantage (*) over declarative even though it does provide support to work on them. (*) except maybe the different helper methods on the Entity base class which can be used as-is, while you need to reimplement (or copy-paste) them on your own base class if you are using declarative. I wouldn't consider this significant though ;-). -- Gaƫtan de Menten http://openhex.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
