Hibernate is an object relational mapping (ORM) suite for Java that allows users to map object-oriented programming models to relational databases. It does so primarily by mapping Java classes to database tables, and Java datatypes to SQL datatypes. Through data query and retrieval facilities, it automatically handles the otherwise-manual process of object conversion from Java. It uses Hibernate Query Language (HQL)—a language similar in syntax with SQL written against Hibernate’s data objects. The latest version supports Java8, Karaf, Jcache, JPA 2.2 and more.
This is a free Apache Subversion client that can be used as a Windows Shell extension. It is useful for programmers to maintain different versions of program codes simultaneously. Its intuitive interface does not require the Subversion command line to run, making it easy to use for all user levels. It also provides icon overlay, which displays the status of Subversion working copies. The latest version includes a major bug fix in the form of rectification of code execution through malicious svn+ssh URLs.
Moodle is an open source free learning management software with highly customisable features. A large list of plugins for various purposes like knowledge, activity, communication, collaboration teaching and so on can be accepted by Moodle to build a stronger learning suite. Some examples include StudentQuiz, Turnitin’s Moodle Direct V2 activity plugin, SAML2 Single sign-on, Content Pages, Feedback Plugin, Advanced Notifications, YU Kaltura Media Assignment, Media Resource and Media Gallery and Custom Course Menu.
KeePass Password Safe
This open source, free software is a Windows-major password management system. It also supports MacOS and Linux with the use of Mono.
