java - New to Object Relational Mapping -

-

i went ahead buy book on hibernate. wanted learn on hibernate , object relational mapping in general.

harnessing hibernate has topics on hibernate , think able write simple mapping classes now. problem is, think way ahead on hibernate dont know why need one.

the book explains hibernate think @ lost cause not bother discuss why need hibernate , orm.

can please give me useful link read orm. google hits not give me clear results. thanks.

i suggest starting @ wikipedia.

from there, follow links @ bottom.

to provide short answer: orm used abstract data storage, database. can serve multiple purposes, among those:

  • application programmers can add , maintain functionality of software without in-depth knowledge of database (you can write code in java, not in sql).
  • it takes away pitfalls of having assemble sql statements strings , therefore eliminates huge source of errors.
  • database optimization independent business logic. ensures better maintainability. optimization can either done orm ( via configuration files) or directly in database (by manually adding index tables and/or query caches). both not take place in actual program code.
  • data providers can more exchanged, because orm offers drivers multiple databases, same functional logic work different products , vendors.
