Access all areas!

Not only can it be difficult to locate the content you need today, it can also be difficult to deliver that content to others in a way that makes it easy to use, while retaining the intellectual property rights associated with it. Solid Information Technology has developed a novel approach to storing, managing, and delivering digital content, using embeddable relational data management and distribution technology.

The amount of digital content has grown dramatically in recent years, with the spread of digital technologies and the explosion of the Internet. While this has opened up access to information on an unprecedented scale, the downside has been that accessing information – and storing and delivering video content, for example – has become a growing challenge.

There is a clear need for advanced technologies to create and retrieve content-related metadata and system data for guaranteeing access to content and taking account of the needs and profiles of end-users and the devices they use.

A developer of carrier-grade relational database management software for building high-performance distributed applications, Solid has been very active in the content delivery area, working through projects such as the European Candela project on video content analysis.

Delivering content effectively

The Solid DB Management System (DBMS), for example, has two separate storage methods: one for in-memory and one for more traditional in-disk-based storage. Both methods can be used simultaneously to manage ’regular’ relational data, or data in limited-length database columns, and ’blob data’, or large binary chunks of data.

Thanks to this dual approach, together with enhanced blob data management, Solid can handle binary data much more efficiently, while preserving full data integrity. This also means that only one API is needed to access data.

Content and metadata can be combined in queries, all data can be treated transactionally, system data can be fully accessed, and all data can be distributed across databases and devices using a unified data-synchronisation mechanism.

Some 90% of Global 500 network equipment providers – including Alcatel, Cisco, NEC, and Siemens – use Solid products as the core data management engine for their applications.

Only part of the story

While content data, and storing and delivering it reliably and efficiently, is important, content itself is only part of the story.

Metadata is critical, as it describes content, makes it searchable, and associates intellectual property rights with content. Maintaining the right linkage between content and metadata is equally critical if a system is to be capable of guaranteeing the availability, integrity, and security of data, especially in the case of personal data or data with commercial value.

Almost all data in a content delivery system, in fact, is valuable to someone.
