Schema updates for object-oriented database systems (abstract)
Roberto V. Zicari · 1992
OODBMS are often used for complex data whose structure is likely to change over time, yet the problem of schema updates has not been completely solved by any commercial or research OODBMS. This tutorial describes the schema modification problem and why it is important, what is really offered by products, what a good solution would be like, and whether we are likely to see it soon.
