I want to make a java application with a rather small database. The pc on which I want to install this has nothing of database stuff on his pc (no wamp server, no oracle, nothing…). I’m rather new in this kind of stuff, and i don’t know if it’s already been asked but this is what i want to accomplish

Now I have a couple of questions:

  1. Is this doable?
  2. What should I use? Mysql, Oracle,…
  3. How can i do this?

I hope this is enough to get a decent answer.

    1. Yes, it is doable.
    2. For use with Java, I strongly recommend Apache Derby because
      • you have the huge flexibility of being able to choose between embedded and client-server db, with no code refactoring needed to change data access mode
      • over H2 or HSQLDB: according to my experience I’ve found Apache Derby
        • to be much more reliable/resilient (other embedded DBMSs tend to break more than derby when power fails)
        • to eat up less RAM
        • to have better performance on bigger deployments (lots of rows, lots of data [in microbenchmarks with little real-world data H2 and HSQLDB can actually score better]).
        • to be particularly fast with select queries in heavily multithreaded environments
      • over MySql and PostgreSql
        • it’s actually faster, when you are not CPU/network -bound, because I’ve seen it perform better than them in many cases (especially with bigger DBs — say 10GB) when it comes to filesystem access (MySql and PostgreSql, however, are more efficient in terms of CPU/network utilization, when these are a constraint)
      • over MySql, PostgreSql, Oracle db, etc.
        • it’s surprisingly fast (often faster), with very big DBs (say, 30 GB) — something one wouldn’t expect from a DBMS you can embed in any application with no deployment/configuration
    3. To get started, see

    If you don’t need clients from the network to remotely connect to your database, an “embedded database” is what you want to implement.

    Flame-preventing disclaimer: all the statements above are according to my very own personal experience, with the projects I’ve worked on and/or articles/benchmarks that I read and trusted as reliable. Unless otherwise stated (and in fact I’m not stating otherwise anywhere 🙂 ), I’m referring to fresh out-of-the-box un-fine-tuned installations.
