Situation Analysis

Agility is the timeless pursuit of enterprises and individuals alike. In all cases, access, integration,

and dissemination of data is pivotal.

Linked Open Data (LOD) Cloud


Situation Analysis


Data is growing exponentially along the

following dimensions:

•Volume -- production

•Velocity – dissemination fire-hoses

•Variety – APIs and underlying data Models

•Virtuosity – insight discovery expectations.

All of this happens while the total hours in day

remains constant at 24 hours!

Product Value Proposition


Enterprise and Individual Agility

via Data Virtualization, without

compromising performance,

scalability, security, or

investments in existing

infrastructure!

Product Architecture


A high-performance, scalable,

secure, and operating-system-

independent server designed

to handle contemporary

challenges associated with

data access, data integration,

and data management.

Data Virtualization Middleware


An in-built middleware layer

(“Sponger”) for creating

Linked Data Views over

Heterogeneous Data

Sources.

Pluggable Linked Data Cartridges/Drivers


A collection of prefabricated

and customizable Data

Extraction, Transformation,

and Lookup cartridges

(drivers) covering a vast

ranges of data formats and

data access protocols.

Sophisticated Content Crawler


DBMS hosted Content

Crawler that leverages

loosely coupled binding to

the Sponger Middleware

component for

transformation of

unstructured and semi-

structured data into Linked

Data.

How Do I Get Going?

Download, install, and experience the power of coherent integration of disparate data sources, data access protocols, and data representation formats.

In an nutshell, commence exploitation of powerful business intelligence, socially enhanced collaboration, data virtualization, and entity analytics without writing a line of code!

Turn "Big Data" into exploitable "Smart Data" without compromise!
