SESSION ABSTRACTS

Dan tells us he came across the naked objects pattern at a conference in 2002, and two years later used an early version of the Naked Objects Framework to build the main benefits system developed here in Dublin for the Irish Government, still running 20+ years later and administering pensions and 40 other benefits.

Since 2012 he and his team have developed an in-house ERP for Eurocommercial Properties on that early framework's successor, Apache Causeway, processing €500m of invoices each year, and with a team averaging 2.5 FTE's.

Dan says you can think of naked objects a bit like an ORM, except it manages the presentation layer rather than persistence. Not having to build the UI layer (or REST APIs) means that you can focus on what really matters, the core business domain.

In this talk Dan will introduce you to Apache Causeway, itself built upon Spring Boot, with live coding and anecdotes along the way.
