OpenLink Virtuoso - Product Value Proposition Overiew

Situation Analysis

Since the beginning of the modern IT era, each period of innovation has inadvertently introduced its fair share of Data Silos. The driving force behind this anomaly remains an overemphasis on the role of applications when selecting problem solutions. Unfortunately, most solution selecting decision makers remain oblivious to the fact that most applications are architecturally monolithic; i.e., they fail to separate the following five layers that are critical to all solutions:

1. Data Unit (Datum or Data Object) Identity,
2. Data Storage/Persistence,
3. Data Access,
4. Data Representation, and
5. Data Presentation/Visualization.

The rise of the Internet, and its exponentially-growing user-friendly enclave known as the World Wide Web, is bringing the intrinsic costs of the monolithic application architecture anomaly to bear -- in manners unanticipated by many. For example, the emergence of network-oriented solutions across the realms of Enterprise 2.0-based Collaboration and Web 2.0-based Software-as-a-Service (SaaS), combined with the overarching influence of Social Media, are producing more heterogeneously-structured and disparately-located data sources than people can effectively process.

As is often the case, a variety of problem and product monikers have emerged for the data access and integration challenges outlined above. Contemporary examples include Enterprise Information Integration, Master Data Management, and Data Virtualization. Labeling aside, the fundamental issues of the unresolved Data Integration challenge boil down to the following:

• Data Model Heterogeneity
• Data Quality (Cleanliness)
• Semantic Variance across Contexts (e.g., weights and measures).

Effectively solving today's data integration challenges requires a move away from monolithic application architecture to loosely-coupled, network-centric application architectures. Basically, we need a ubiquitous network-centric application protocol that lends itself to loosely-coupled across-the-wire orchestration of data interactions. In short, this will be what revitalizes the art of application development and deployment.

The World Wide Web is built around a network application protocol called HTTP. This protocol intrinsically separates the five layers listed earlier, thereby enabling:

• Use of Generic HTTP URIs as Data Object (Entity) Identifiers;
• Identifier Co-reference, such that multiple Data Object Identifiers may reference the same Data Object;
• Use of the Entity-Attribute-Value Model to describe Data Objects using real world modeling friendly conceptual graphs;
• Use of HTTP URLs to Identify Locations of Resources that bear (host) Data Object Descriptions (Representations);
• Data Access mechanism for retrieving Data Object Representations from persistent or transient storage locations.

What is Virtuoso?

A uniquely designed to address today's escalating Data Access and Integration challenges without compromising performance, security, or platform independence. At its core lies an unrivaled commitment to industry standards combined with unique technology innovation that transcends erstwhile distinct realms such as:

• Data Management (Relational, RDF Graph, or Document),

• Data Access Middleware,

• Web Application & Services Deployment,

• Linked Data Deployment, and

• Messaging.

When Virtuoso is installed and running, HTTP-based Data Objects are automatically created as a by-product of its powerful data virtualization, transcending data sources and data representation formats. The benefits of such power extend across profiles such as:

• Information & Knowledge Workers,

• Systems Integrators & Architects,

• Distributed Collaboration & Social Media,

• Cloud Computing, and

• Application Development.

Product Benefits Summary

• Enterprise Agility — Virtuoso lets you mix-&-match best-of-class combinations of Operating Systems, Programming Environments, Database Engines and Data-Access Middleware when building or tweaking your IS infrastructure, without the typical impedance of vendor-lock-in.

• Data Model Dexterity — By supporting multiple protocols and data models in a single product, Virtuoso protects you against costly vulnerabilities such as: perennial acquisition and accumulation of expensive data model specific DBMS products that still operate on the fundamental principle of: proprietary technology lock-in, at a time when heterogeneity continues to intrinsically define the information technology landscape.

• Cost-effectiveness — By providing a single point of access (and single-sign-on, SSO) to a plethora of Web 2.0-style social networks, Web Services, and Content Management Systems, and by using Data Object Identifiers as units of Data Virtualization that become the focal points of all data access, Virtuoso lowers the cost to exploit emerging frontiers such as socially-enhanced enterprise collaboration.

• Speed of Exploitation — Virtuoso provides the ability to rapidly assemble 360-degree conceptual views of data, across internal line-of-business application (CRM, ERP, ECM, HR, etc.) data and/or external data sources, whether these are unstructured, semi-structured, or fully structured.

Bottom line, Virtuoso delivers unrivaled flexibility and scalability, without compromising performance or security.
