NoSQL is a fast, portable, relational database management system without arbitrary limits. It runs under, and interacts with, the UNIX operating system. It uses the Operator/Stream DBMS paradigm. There are a number of "operators" that each perform a unique function on the data. The "stream" is suplied by the UNIX input/output redirection mechanism. Therefore each operator processes some data and then passes it along to the next operator via the UNIX pipe function. This is very efficient as UNIX pipes are implemented in memory. NoSQL is compliant with the relational model.
SymmetricDS provides file and database synchronization with support for multi-master replication, filtered synchronization, and transformation across the network in a heterogeneous environment. It supports multiple subscribers with one-direction or bi-directional, asynchronous data replication. It uses Web and database technologies to replicate data as a scheduled or near-realtime operation. The software has been designed to scale for a large number of nodes, work across low-bandwidth connections, and withstand periods of network outage. It works with most operating systems, file systems, and databases, including Oracle, MySQL, MariaDB, PostgreSQL, MS SQL Server (including Azure), IBM DB2, H2, HSQLDB, Derby, Firebird, Interbase, Informix, Greenplum, SQLite (including Android), Sybase ASE, and Sybase ASA (SQL Anywhere) databases.
SAGU, which is a portuguese acronym for "Sistema Aberto de Gestão Unificada", was originaly designed to automate all of what that happens between a student and their Educational Institution. This relationship happens at the academic, financial and administrative levels, and SAGU has subsystems dedicated to these levels. SAGU can be tailored to fit the needs of any Educational Institution.
