Guides

  • ORM:first_example ## First example ## Let's have a look at a simple example where we want to persist a certain CFC to a MySQL database. Further below all necessary steps in order to get ORM to work with Lucee are described. We will assume the following scenario: We have an easy blog where an author can submit his blog post containing the following properties for an entry: * author * publish date * title * teaser * text * tags Nothing more for the moment
  • ORM:introduction ### ORM with Lucee ### This section is going to describe how ORM (object relational mapping) is handled by Lucee 3.2 Server. Lucee Server uses Hibernate in the background for implementing ORM. If you want to learn more about Hibernate, just check the corresponding [documentation](http://www.hibernate.org/). ### What is ORM ? ### According to Wikipedia ORM is: Object-relational mapping (ORM, O/RM, and O/R mapping) in computer software is a programming technique for converting data between incompatible type systems in object-oriented programming languages
