java - Jpa understanding for interview -

-

what best description of jpa?, interview answer comprehensive yet detailed ? answer:: java persistence api java application programming interface specification describes management of relational database in java platform , divided 3 parts persistence entity ,persistence query language , object relation database metadata

assuming you're going interview solid understanding of jpa, don't worry memorizing standard definition.

interview questions way of gauging applicants level of familiarity given subject. want response both reflect understanding of subject matter, , importantly, tailored in concise manner context of question. if asked why jpa useful, not describe history of specification, or provide memorized definition- avoid being verbose in case indicates lack of confidence in answer, or @ worst lack of understanding.

if question asked verbatim "what best description jpa?"- sounds want abstract, high-level response indicates understanding of specification iteself. response might "jpa specification provides common interface clients working relational data, regardless of underlying persistence implementation" - note response concise , not attempt answer any questions weren't asked, such as:

  • what orm/how orm work
  • difference between jpa , orm
  • what main 3 components of jpa defined on wikipedia (the oracle docs divide jpa four areas, both arbitrary imo)
  • provide example of jpa implementation
  • etc

if they're looking more information, they'll ask- don't provide more have to. question answered , correctly, because chances are, have follow questions they're planning ask.

the solution question confidence in ability perform in interview, gained via preparation- in part, studying.
