    NetBeans and data consistancy guarantee without large DBMS (simpletransactional database / ACID support)

    Hello. I haven't used NetBeans yet and I haven't programmed much Java (I've programmed more in C++), but I have a question:

    Can I get a data consistancy guarantee when writing to a file from Java if I use the NetBeans IDE package without using a large DBMS?

    I mean, does Java standard classes or some NetBeans packages support some kind of simple transactional database / ACID support or similar? Or maybe some good third-party packages can do this (although the best would be if Java itself can "help me out" here)? I'm going to program for several operating systems and different platforms (standard PC's, but also pretty low performing mobile platforms), so I do not want to use MySQL, PostgreSQL or similar "large" DBMS's.

      If you want a transactional relational DBMS then look at one of the Java based
      RDBMS. There are three major players in this field:

      - H2 Database (www.h2database.com)
      - Apache Derby (http://db.apache.org/derby/)
      - HSQLDB (www.hsqldb.org)

      Apache Derby comes packaged with the JDK under the name "JavaDB", so this might
      qualify as a "Java standard".

      All three offer an embedded mode where no additional server is required, but all
      of them have some limitations when it comes to very large datasets.
