Databases and web sites

What services do we offer?

Our web work is primarily in the business-to-business area, especially the web equivalent of technical publishing. We can design web sites and manage them on a day-to-day basis if required but will often work with the client's design to automate and build a site.

Design and development

We use a variety of software to produce whatever level of dynamic updating is required. Suitable content is either provided by our clients or is developed jointly. This includes the production of photographic, audio and visual assets. We believe it is important to develop sites that give a similar experience to the visitor whatever device is being used to view the pages and now take a responsive view of web page design.

PS: This web site is built using Twitter's Bootstrap framework including Jan Kovařík's Glyphicons.


We are experienced in the use of PHP, Perl and MySQL to derive dynamic pages from databases and algorithmically. We are particularly proud of the broadcast reception databases and of the news database used to power the news section of the DTG Web Site.


The day-to-day running of a web site for a client is needed if the site has some ever-changing content but the circumstances (and/or budget) do not require a full content management system. We have developed hybrid web sites geared towards regular updating.

Projects and clients

Broadcast reception prediction databases

PCD query input on a web page

We worked with the BBC, Digital UK, Digital Radio UK and others to produce and manage databases of coverage predictions for digital television and radio. These were initially set up in 1997 to assist with the UK's digital switchover and have evolved ever since. The original data was for DTT and DAB was added more recently.

If you look up your reception prediction on web sites from Digital UK, Freeview and BT Vision (amongst others) you will be accessing this web service. It's known as the PCD, the Predictive Coverage Database, or more popularly as the 'Postcode Checker', and currently this runs at over a million enquiries a month.

The PCD web service uses the open XML-based standard SOAP for its API and is programmed in PHP using MySQL for the database. Reception prediction data is provided by the BBC on behalf of the UK broadcast planning team.

We are currently working on a project for the BBC improving the reporting of fault conditions in radio and television networks and transmitters.

Webmastering for the Digital TV Group

DTG web site

The web site is the shop-window for the Digital Television Group, who are the industry body representing the digital television industry in the UK.

In 2015 the site was reimagined using Bootstrap to provide a responsive experience while simplifying and improving the user experience.

News is input into the site's news system directly by the DTG's journalists and other pages are regularly updated by the DTG or by ATSF from copy provided by the DTG. The news section is driven entirely from a MySQL database allowing sophisticated keywording and searching. Databases are also used for other dynamic parts of the site.

The Elektra Master Discography

With the encouragement of the label's founder and under licence from Warner Music Group, we built a comprehensive database of the famous American record label, Elektra. The database covers the period from its foundation in 1950 to when the founder, Jac Holzman, left the label in 1973.

As well as the database itself, for its 60th anniversary Andy Finney undertook to photograph the entire canon of album covers for inclusion in the book Becoming Elektra, chronicling the history of the label. He also rescued and processed several rare elderly recordings for use on WMG's anniversary web site for the label.
