Mendip Data Systems

Database applications for businesses and schools


About us

Mendip Data Systems are based in the Mendip Hills in Somerset, UK.

For many years, we specialised in creating management software for schools though we have now widened our remit to include applications for business/personal use.


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, email us - [email protected] - 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


We currently have 9 applications available for purchase:


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)


•    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 to supply full program code so that schools can customise the program features to suit individual needs.


•   School Data Analyser


•    SDA Link


•    Curriculum Enrichment Organiser


•    School Payments System


•    Exam Timer


•    Student ICT Database (source code edition)
