Modern Web or ¿Eternal-Beta¿ applications necessitate a flexible and easy-to-use data management platform that allows the evolutionary development of databases and applications. The classical approach of relational database systems following strictly the ACID properties has to be extended by an extensible and easy-to-use persistency layer with specialized DB features. Using the underlying concept of Software as a Service (SaaS) also enables an economic advantage based on the ¿economy of the scale¿, where application and system environments only need to be provided once but can be used by thousands of users. Within this tutorial, we are looking at the current state-of-the-art from different perspectives. We outline foundations and techniques to build database services based on the SaaS-paradigm. We discuss requirements from a programming perspective, show different dimensions in the context of consistency and reliability, and also describe different non-functional properties under the umbrella of Service-Level agreements (SLA).

For two decades, the 2005 UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions (DCE) has played a pivotal role in shaping international cultural policy. This article explores the actual relevance of the Convention's Objectives against the backdrop of current global challenges such as poverty, climate change, digitization, and gender equality. The authors reflect on the Convention’s effectiveness in fostering international cooperation, supporting cultural policies, and promoting the inclusion of culture in development agendas. Notwithstanding emerging obstacles, the Convention’s framework has consistently been reaffirmed and shown dynamic adaptability to new developments, particularly through its doctrinal intersections with human rights law and its influence on States’ cultural policies. Key institutional mechanisms such as the International Fund for Cultural Diversity and initiatives like the 'Fair Culture' movement underscore the Convention’s role in promoting sustainable cultural development and equitable trade in cultural goods and services. In conclusion, with its broad framework of Objectives, the 2005 Convention remains a vital instrument in fostering cultural diversity, capable of responding to evolving global priorities while advocating for solidarity and creative collaboration among member States and civil society.:Introduction 1 A.
