It is thus generally accepted that the support for sequenced data in databases is important. Sequenced data also appear in business applications in the forms of temporal data and time series. Easy querying and efficient management are two essential aspects for supporting sequenced data in databases. Easy querying requires that the query language be intuitive and expressive. Most current database systems are not equipped with such a query language.
Efficient management requires, in part, that queries data mining requests be efficiently evaluated.
This project is to study these two aspects. Area References S. Vandenberg and D. DeWitt. Algebraic support for complex objects with arrays, identity, and inheritance. S. Ginsburg and X. Wang. D.Maier and B.Vance.
