Any number of technologies can be applied to solve similar application challenges that the XPress solution addresses. Each alternative solution addresses a technical need, and each solution also has technical drawbacks that XPress design deliberately addresses.
Relational databases provide a robust data model and proven generality, but were not designed for rapid message interaction, efficient networking exchange, high update performance, and cost-effective native scalability.
Directory services offer superior cost efficiencies compared against relational models, but the replication model will not support high update capacity. Performance depreciates as distribution increases.
Phone switching technologies offer high performance, proven distribution and reliability, but are protocol and application specific, and not designed for IP network traffic. These technologies were not designed to be databases.
DNS (Domain Name Service) provides proven distribution and excellent scalability for specific function, but is protocol restrictive, designed for particular objects, handles mobile objects poorly, has an inefficient replication model, and has extremely limited query and data models.
The XPress
Solution
At the core of XPress is a networking protocol
that runs over TCP/IP and UDP/IP, which provides a
patent-pending clustering and replication
technology that linearly scales to any imaginable
degree. XPress supports conventional
vertical scaling through machine
and middleware upgrades, or horizontal
scaling through concatenating low-end
equipment and standard networking infrastructure,
to support multiply-concurrent services in a
common database backend, at greater performance
levels than other, even specialized
alternatives.
XPress provides excellent distribution properties, real-time lookup and update transactions at wire-speed across the network, and per-instance replication tunable to any desired performance level. No other available technology can match the performance, scalability, distribution, or efficiencies that XPress provides.
The XPress association database addresses precisely those needs for which other technologies were neither designed nor built to address. Against its proper application domain, XPress provides superior performance, and on a radically improved computational and financial cost-basis, with unlimited scalability.
XPress is not designed to "replace" other technologies for their designed purposes, but rather is designed to solve common problems in a new, generically understood distributed arena that alternative technologies do not appropriately or cost-effectively address.
