GigaBASE is object-relational embedded database engine for C++ applications. It provides SQL-like query language, smart C++ interface (loading objects instead of tupples), transaction based on shadowing page algorithm (no separate log file and very fas

...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.

Levin is an event-based key/value server based on radix-tree (space optimized trie). Key search can be performed with an approximate key matching algorithm based on Levenshtein edit distance.

Extreem Reader for Cosmological simulation data P-Gadet2 and ART codes.It conserves memory by using memory mapped files. Contains some basic analysis tools such a KD-Tree, Minimum Spanning Tree, and rendering module using PMViewer algorithm.

...SafePassDB is a free multi-platform software application written in Java programming language that will enable you to protect all of your personal data with one "Master Password" using AES (Advanced Encryption Standard). SafePassDB is light weight and super easy to use! Current version of the software uses 128 bit AES (Advanced 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/

The sqlite3fish is another encryption solution for sqlite3. It is based on some source code of botansqlite3(https://github.com/OlivierJG/botansqlite3) . But it does not need Botan library, it uses Blowfish algorithm to encrypt/decrypt the database file. This library only depends on the source code(no-modify) of SQLite3, it is clean and easy to compile. But currently it only supports the version 3.7.0 of SQLite3 (http://www.sqlite.org/sqlite-amalgamation-3_7_0.zip) .

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 in practical situations significantly.
