About Mendip Data Systems / Isladogs

My name is Colin Riddington and I am the owner of Mendip Data Systems. I am also active on many online forums - usually with the user name isladogs.

Since 2005, Mendip Data Systems have been based in Somerset, UK.
Previously we were on the edge of the
Mendip Hills (hence the name), but we moved to a remote area of the Exmoor National Park in 2019.

For many years, we specialised in creating management software for schools though we now focus on apps for businesses/developers.

The advantage of being a small development operation is that clients don't have to pay for large company overheads when they purchase our products - and users can talk directly to the key people in the company when they contact us.

However, sometimes we may not be available, and you may need to leave us a message - or better still, send us an email because we respond to emails quickly and at any time.

The site includes several commercial applications as well as a wide range of free example applications, code samples and extended articles.

We also accept customised work for individual clients including both the creation of new systems and upgrading existing applications.
In addition, we can
convert old databases to current versions and advise on issues related to database security.

We currently have 10 applications available for purchase from the website:

Apps for Business / Developer / Personal Use
The focus here is on creating applications based on imported online data obtained in JSON format.
-    JSON Analyse & Transform for Access (for Access developers)
-    UK Postal Address Finder (Professional/Standard/Tablet editions) <
-    UK Postal Address Lookup (source code edition)
-    Currency Exchange Rate Tracker (source code edition)

Applications for Schools
All our school applications were originally developed to for use in UK secondary schools.
However, many of these are equally suitable for use in primary schools and abroad.
Most of these applications for schools are open source databases using Microsoft Access and SQL Server.
We regularly update our programs to meet the changing needs of schools.
It is also our policy in most cases to supply full program code so that schools can customise the program features to suit individual needs.

-    SDA Link
-    Curriculum Enrichment Organiser
