Package de.dlr.proseo.model.dao

package de.dlr.proseo.model.dao

This package contains data access object (DAO) classes for the common data model of prosEO. For the DAO design pattern see also @link{https://en.wikipedia.org/wiki/Data_access_object}. All DAO classes are derived from BasicDAO<T>, which implements basic CRUD functions using JPA. While BasicDAO<T> can be used directly, model class specific DAO classes may be derived to provide additional functionality (e. g. a search based on specific class attributes). Usage of all DAO classes follows the pattern shown below:

  // Open database connection
  EntityManager em = emf.createEntityManager();
  em.getTransaction().begin();
  ...
  // Get the Product object
  BasicDAO<Product> productDAO = new BasicDAO<Product>(em, Product.class);
  Product myProduct = productDAO.get(myProductId);
  ...
  myProduct.setDescription(newProductDescription);
  productDAO.update(myProduct);
  ...
  em.getTransaction().commit();
  em.close();
