    RoaringBitmap

    RoaringBitmap

    A better compressed bitset in Java

    Bitsets, also called bitmaps, are commonly used as fast data structures. Unfortunately, they can use too much memory. To compensate, we often use compressed bitmaps. Roaring bitmaps are compressed bitmaps which tend to outperform conventional compressed bitmaps such as WAH, EWAH or Concise. In some instances, roaring bitmaps can be hundreds of times faster and they often offer significantly better compression.

    BIMserver

    BIMserver

    The open source BIMserver platform

    The Building Information Model server (short: BIMserver) enables you to store and manage the information of a construction (or other building related) project. Data is stored in the open data standard IFC. The BIMserver is not a fileserver, but it uses a model-driven architecture approach. This means that IFC data is stored as objects. You could see BIMserver as an IFC database, with special extra features like model checking, versioning, project structures, merging, etc. The main advantage of this approach is the ability to query, merge and filter the BIM model and generate IFC output (i.e. files) on the fly. ...

    RxJava

    RxJava

    Reactive Extensions for the JVM

    ...It helps you write cleaner and simpler code by providing methods for solving problems quickly, and is easy to maintain and understand. RxJava works by extending the observer pattern in order to support sequences of data/events. It also allows you to compose sequences together declaratively through added operators, all while abstracting away concerns like low-level threading, thread-safety, concurrent data structures and synchronization. RxJava is commonly used for running simple background computations. It supports Java 6 or higher and languages that are based on JVM such as JRuby, Groovy and Clojure.

    Depeche

    Depeche

    Java database mapper

    Depeche enables you to work with databases using data structures. It strives to be very simple and easy to use, avoiding both the tediousness of using JDBC directly and the heaviness of a full-blown ORM. It currently supports PostgreSQL, MySQL, H2, SQLite, MS SQL Server and FileMaker; support for other databases can be added easily. A simple ORM based on Depeche is also under development.

    Moelnir

    Moelnir

    Heap organised database service (Java library)

    Moelnir is a basic database file, addressing variable record data through integer identifiers, which applies heap organisation of its data space. Advantage of Moelnir is that each record is stored in a continuous segment on the file while still record size is limit-less variable and modifiable. There are no data length limits other than the range of a 63-bit unsigned integer. Scalability is limited to 1 - 10 Mio. entries due to non-paging internal structures.

    SPARGEL

    SPARGEL

    An opensource Java graph library. Abandoned, ignore.

    ...Because these maps are an individual implementation depending on the graph datastructure used, they are more memory efficient than using a Java HashMap. Currently spargel is in its early stages, but will soon support more tasks. As now, implemented are: * Adjecency graph data structures * Algorithms: SSSP, APSP, Traversal, Min-Cut, Max-Flow, Many types of finding Components * Creating sub graphs, vertice and edge maps that use a function to implement their mapping. Spargel is released under GPLv3
