I have created Entity Relationship Diagrams and going to learn JPA now. I want to smooth my skill of ER diagrams according to DB requirements more and learn more about Object Relational Mappings up to an expert level. Involving in real project development may increase my ORM knowledge and experience. (Currently what I do is, just think and draw and no one to guide me.
) But I d like to have good learning sources for a better knowledge, experience in database designing, ERD, ORM s . I request from all you experts any links,samples, books which may help me. Thanks in advance
