Object Query For Linux

Object Query is an open source, platform-independent and freely distributed command-line software implemented in the Java as an small utility for writing refactor-resistant and type-safe queries that feature cross persistence technology.

Installing and using the Object Query software on your GNU/Linux operating system is an easy task, as it can be easily installed via Maven, so you will have to insert a specific Maven dependency for each implementation, including JPA (Java Persistence API), JDO (Java Data Objects), OrientDB, and Hibernate. Object Query is distributed on Softpedia as a tarball that contains all the source files of the project.

If you want to see a simple example of how Object Query works, please check out the code below. Also, make sure that you visit the project’s homepage (see link at the end of the article) for detailed documentation and other examples.

SelectQuery< Person > query = new GenericSelectQuery< Person >(Person.class); Person toSearch = query.target(); query.prj(toSearch.getName()); query.eq(toSearch.getMum().getName(),"elisabeth"); query.gt(toSearch.getAge(),20); query.order(toSearch.getName());

Taking a look under the hood of Object Query, we can notice that the program is written entirely in the Java programming langauge, which means that it’s a platform-independent application supported on the Linux, Microsoft Windows and Mac OS X operating systems. It has been successfully deployed on computers supporting either of the 64-bit or 32-bit instruction set architectures.
