The Science Archives implemented by ESAC Science Data Centre (ESDC) are the final data repositories of the ESA missions. Their software architecture has experienced significant changes since the first archive was released in 1998. The evolution resulted in several generations of archives adopting the latest state-of-the-art technologies and improving the user experience dramatically.

The Integral Science Legacy Archive (ISLA) is one of the newest archives in which special effort has been dedicated to engaging the mission scientists to develop a science-oriented archive. In addition, special care has been taken in offering the best user experience moving from the classical data-forms flavour to dedicated Integral Science Portals. In this talk, we will walk through those Integral specific sections and see how this approach has inspired other ESDC archives.

The implementation of ISLA has been driven by the UX design paradigm and the adoption of mature software tools like Angular. This Javascript framework promotes highly performant and usable applications. It can be considered a dedicated platform that supports the implementation of responsive, efficient, and high-quality cross-platform solutions.

In the talk, we will see the importance of being up-to-date and using the latest technologies in order to get powerful and maintainable tools that fulfil complex science use-cases.
