Collections Or Arrays

If you are planning an application with db4o, you may be asking yourself, what is better to use: collections or arrays? In the current implementation it is not really a difficult choice, as collections internally are stored as arrays, which is explained in Collections chapter. You can base your solution on the overall system design, entrusting db4o to handle the internals efficiently in both cases.

However if you are looking into the future you might want to design your system in a way that can easily be switched to the next db4o planned feature: Fast Collections. For more details see Fast collections. Please, feel free to use db4o Jira to track the feature progress and be notified on the latest updates.
