Consider a java programmer wants to access database via ORM tools like Hibernate. In this case pick any open source projects which use database. The choice could be content management system or forum software. Among that pick Java projects and see which all use Hibernate to connect to database. Shortlist one or two and download their source. Search the source for hibernate related keywords. Most of the projects are object oriented and only one or two class will be responsible to access it to the database. Pick the class and learn the code. Reuse if possible.

If you want to learn anything related to generating charts, then pick projects related to reporting and analyze its source. If you want to learn any PHP based framework, then pick a CMS project which uses that.

This should be a like a habit, learn about one open source projects once a day or a week. Read their site and learn their design. What all the components they use to build their projects. Download the source and peep in to the lib directory to get the list of dependency. There are many small libraries which could make our life easier. Bookmark it and use whenever required.

Please feel to add your comments and write how would you learn.

Advantages and Disadvantages of using Hibernate like ORM libraries

Traditionally Programmers used ODBC, JDBC, ADO etc to access database. Developers need to write SQL queries, process the result set and convert the data in the form of objects (Data model). I think most programmers would typically write a function to convert the object to query and result set to object. To overcome these difficulties, ORM provides a mechanism to directly use objects and interact with the database.
