Hi, 

I'm working with Liferay 7.2 and I need to fetch some data from an external database which is not managed with Service Builder (the tables already exist and I have just read-only access to the database).

Which is the best way to implement this kind of integration? Basically I would like to implement my own DAOs and my custom SQL queries trying not to add additional dependencies other than the one already inlcuded by default in Liferay

 

Regards,

Pietro
