... Gremlin graph query language and RESTful API but also provides commonly used graph algorithm APIs. To help users easily implement various queries and analyses, HugeGraph has a full range of accessory tools, such as supporting distributed storage, data replication, scaling horizontally, and supports many built-in backends of storage engines.

Java API to realize quick ISAM (Index Sequential Access Method) functionality for application in the file system. Includes scalable database files w/ space recovery and variable record length, scalable B+Tree index files. Supports file backup and restore. Two package types: one with and one without strong file encryption using Twofish algorithm and state-of-the-art encryption technology.

CliqueSquare is a system for storing and querying large RDF graphs relying on Hadoop’s distributed file system (HDFS) and Hadoop’s MapReduce open-source implementation. It provides a novel partitioning and storage scheme that permits 1-level joins to be evaluated locally using efficient map-only joins. In addition, CliqueSquare is equipped with a unique optimization algorithm based on graphs and cliques capable of generating highly parallelizable flat query plans relying on n-ary equality joins.

... Encryption Standard) algorithm, which is a standard by U.S. National Institute of Standards and Technology (NIST), for protecting your personal data. IMPORTANT: In order to run SafePassDB you need to have Java installed on your computer. Java is free and can be downloaded from - http://www.java.com/

Semantic query optimization (SQO) is the process of finding equivalent rewritings of an input query given constraints that hold in a database instance. We present a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the pegasus system, outperforms existing C&B systems an average by two orders of magnitude. This gain in performance is due to a combination of novel methods that lower the complexity...

XTEA (eXtended Tiny Encryption Algorithm) support for db4o open source object database. XTEA is a block cipher that operates on a 64-bit block size with a 128-bit key. An extremely tiny but very fast encryption algorithm (with cycles less than 32 rounds)

jIntersect is an OLAP like Java algorithm that takes a JDBC ResultSet as input and returns a data structure with all possible intersections, combinations and permutations of the data, pre-summarized at multiple levels for quick access.

A disk based production quality RTree based upon Guttman’s quadratic split algorithm having following features: Buffering with dirty write, Index joins, Tree Seeding, Window and NN queries, Runtime STR Packing capability, Completely Thread safe.

A similar to Tripwire, file system integrity checking tool but develop in java and cross platform. This tools checking and source control using check sum algorithm like MD5, SHA and CRC.
