Title: Object Relational Mapping as Optimization Layer
Time: 9:30

Speaker: Piotr Wisniewski

Object Relational Mappings systems are useful tools in architecture of software. Unfortunately these systems are known as bottleneck of  efficiency of querying. On the talk there will be presented opposite view – ORM layer could be used to store some optimization technics.
The technics integrated by author with ORMs are: Querying recursive data (not only Recursive Queries) and various usage of redundant data. At the end, there be shown some example of bad constructions in Hibernate.
