Sav Zigzag is a Java API forming new powerful "Java/Zigzag" language, for development of a high-performance mobile object-relational database application.

Main advantage of Zigzag to SQL is manipulation with classes (in addition to relations).

Zigzag algebraic expressions enable to process XML data with dynamic structure and multi-level hierarchy.

Unlike XSLT, Zigzag is not data filter; it reads many of XML files in one database and then generates and prints new XML files.

The Sav Zigzag, working under one JVM, provides synchronous connection many of users with many of local databases.
