Dear reader,
As I announced earlier today, there is no BCS SPA meeting in August this year. However, on the same date there's another event for you to attend, either in person or online, organised by the London regional branches:
https://www.bcs.org/events-calendar/2024/august/hybrid-event-data-needs-testing-too/
Speaker: Ron Ballard - Database Consultant and Author
Agenda
6:30pm - Hybrid event start
8:00pm - Presentation ends with networking and refreshments for those attending at BCS London
9:00pm - Event close
Synopsis
Application developers typically test their code, often with large suites of automated tests, before each new release.
But, when the application is running live, it will be receiving data from multiple sources, over which we may have little control, and that data will sometimes be unexpected and invalid in some way.
The impact of this can be dramatic, as with the faulty flight plan that brought Gatwick to a standstill on 28 August 2023. Several days of chaos were caused by one bad flight plan breaking a system that had been running reliably for years.
The impact was estimated at £100 million.
In this talk we look at:
* the various ways in which data can enter your application
* what can be done to defend against bad data in each case
* practical techniques for profiling and cleaning data sources
* monitoring the quality of data in your systems
About the speaker
