Data Layer

VXSN (Very eXtinsible Stored Nodes) is a data layer utilizing the file system directory/file paradigm to form the basis of node-tree data store. The term data layer is an abstract representation of a data access layer that is defined as "a layer of a computer program which provides simplified access to data stored in persistent storage of some kind." VXSN was designed to provide networked application developers with a data layer that can be rapidly adopted and deployed.


Installation is straigtforward and simple. See Getting Started in the Downloads section for application-specific deployment instructions. For server applications, the server user must have read and write privileges to the absolute data path.

PHP users. VXSN has been tested on PHP 5.4+ and 7.0+ on ext3, ext4 and NTFS volumes. The bcmath library is a required dependency. Be sure your PHP install supports the bcpow function. The AWS S3 SDK for PHP (v2 or v3) is required for S3 replication.
