Interactive Schema Integration with Sphinx
Abstract. The Internet has instigated a critical need for automated tools that facilitate integrating countless databases. Since non-technical end users are often the ultimate repositories of the domain information required to distinguish differences in data types, we suppose an effective solution must integrate simple GUI based data browsing tools and automatic mapping methods that eliminate technical users from the solution. We develop a meta-model of data integration as the basis for absorbing feedback from an end-user. The schema integration algorithm draws examples from the data and learns integrating view definitions by asking a user simple yes or no questions. The meta-model enables a search mechanism that is guaranteed to converge to a correct integrating view definition without the user having to know a view definition language such as SQL or even having to inspect the final view definition. We show how data catalog statistics, normally used to optimize queries, can be exploit...
