The Snippet Engine (SnEn)
Oracle Database Architectures
Are Extremely Complex,
And Very Expensive.
All of Their Complexity Goes Away !
The Snippet Engine Network Architectures
Are Very Simple, Cheaper, and Much Faster.
The Snippet Engine Uses
CPU-Threads as SnEn Nodes
That Act Like “Cyber Ants”.
Thousands of Them,
Each Working Autonomously and Together
Forming a Very Powerful Worldwide Network
All of This Complexity Goes Away !
SnEn Architecture Is Based On Modern Computers,
With a Very Simple Configuration

In Real-Time: Each Node will duplicate its portion of the Database
to other Nodes, running anywhere in the world.
This means that each Database Table is instantaneously duplicated
on other Servers. Each duplicate is a “hot backup”, so that
if one Server should fail, another Server instantaneously steps in.

Nodes are “Cyber Ants” are CPU-Threads
They are always “Alive”
They are always “Talking”
They are always “Thinking Ahead”

ORACLE: The Database Elements are not protected
against multiple Servers concurrently using them.
The Database Tables are spread across multiple Disks.
This means that Oracle must insert software
and overhead to manage the concurrent access.
Thus, Data Elements are
“forced” into isolation for concurrent access.
Database Elements and Tables
SnEn: The Database Elements are automatically protected
against multiple Servers concurrently using them.
The Database Tables are spread across the Servers (not disks).
Thus, each Node completely isolates its portion of the Database.
Each Table is managed by its own code, executing at the lowest level.
There is no overhead !
The Database is managed by its own code,
that always executes as a Core-Thread, and cannot be interrupted.
Thus, all Data Elements are automatically isolated for concurrent access.

Any Node Talks To Any Node
Any Node can talk to any other Node, running on any computer in
the world. Creating interacting applications that share synchronized
data and capabilities is very easy, as this is part of the SnEn design.

Nodes ensure that the Data they manage
is duplicated to other Servers.
This is done directly, Node to Node, and in real-time.
If any Server fails,
another Server instantaneously steps in.
A User never even knows the failure happened.

Database Tables Are Duplicated On Servers Running Anywhere In The World.
If one part of the world has a power failure, other Servers are not effected.
Thus, each Table always has a “hot backup”, and the Network never has any downtime.
Nodes Manage The Database Tables
Each Browser, via the Hosting PHP code, effectively communicates directly with any
Node in the worldwide Network. This is the same as saying that each Database Table
interaction is automatically distributed to a specific Server for very fast processing.
The Database Tables are each managed by a specific Server, and by a specific Node on that Server.
Each Table is automatically duplicated to other Servers for “hot backup”.
In this diagram of 36 Servers, each Database interaction is automatically directed to the Server managing that Table.
This means that there are no “Database Bottle Necks”, and no “Single Point of Failures”.
This simple Architecture is much faster than the Oracle Architecture.
If a Server fails,
another Server instantaneously steps in.
The User never even knows it happened.
Nodes which manage Database Tables, are
intelligently spread across the Network’s
