ORM is "Object Relational Mapper".
If you are taking data out of a relational database and mapping it into objects, you are implementing an ORM.
Seems like I'm sticking to the exact definition of an ORM, aren't I?
- dragonwriter 12y ago> If you are taking data out of a relational database and mapping it into objects, you are implementing an ORM. No, ORM is a particular approach to doing that; the query abstraction approach described upthread is closer to the DAO pattern, to which ORM is an alternative. People were using RDBMSs to provide a persistence layer for OO programs before ORM was a thing, but as you have broadened the term any use of an RDBMS to store/retrieve data used in an OO program would be "ORM".
- zak_mc_kracken 12y agoNow you're the one using a nonstandard definition of ORM. Here is how Wikipedia defines it: Object-relational mapping (ORM, O/RM, and O/R mapping) in computer science is a programming technique for converting data between incompatible type systems in object-oriented programming languages.
- dragonwriter 12y ago"is a technique for" does not mean "includes every technique for". Spearfishing is a technique for catching fish, but not every technique for catching fish is spearfishing.
