Sven Lüppken has a degree in computer science, which he passed with distinction. He is currently employed as Java Software Developer at one of the leading broadcasting and production companies in Germany. Sven started programming in C and C++ at the age of 16 and quickly fell in love with the Java programming language during his studies. When he got the chance to write his diploma thesis about object-relational mapping technologies he accepted at once. Since then, he has integrated Hibernate and the JPA in many projects, always in conjunction with the Spring framework.
