Based on a real-world case study in agile development, the authors examine issues of schema evolution in state-of-the-art object databases. In particular, they show how traditional problems and solutions discussed in the research literature do not match the requirements of modern agile development practices. To highlight these discrepancies, they present the approach to agile schema evolution taken in the case study and then focus on the aspects of backward/forward compatibility and object structures. In each case, they discuss the impact on managing software evolution and present approaches to dealing with these in practice.
