How many entity beans used and how many tables can u use in EJB project ?

EJB architecture is scalable and could scale to any number of tables. However each entity bean represents a business object and is typically represented by a table in the persistent storage mechanism. As number of ejb's increase their complexity increases as well. This "could" cause performance issue and hence the schema of these business objects

should be rechecked.
