Data Integration

In this class we will cover data integration from a very theoretical (in the database sense) perspective. There are two readings:

Maurizio Lenzerini: Data Integration: A Theoretical Perspective. PODS 2002: 233-246. We are reading this paper because it gives a good overview of what data integration is and the systems that are behind it.
Jeffrey D. Ullman: Information Integration Using Logical Views ICDT 1997: 19-40. We are reading this paper because it gives a detailed illustration of some of problems that occur in data integration applications.

To successfully complete this reading, be ready to write a good response and be prepared for a good in class discussion, I suggest the following strategy:

For the first paper:
- Read all of Sections 1 through 5. Don't worry too much about the bulleted list of views in Section 3.1. Don't worry about what description logics are.
- Skim Sections 6 and 7
- Read Sections 8 and 9
The second paper should be well motivated and fairly easy to understand given the first paper. If not, skim sections 1 and 2, then read sections 3. Refer to section 2 when stuck, and read all of 1 and 2 carefully when done. I'll also hand out a short set of homework problems to make sure that you have something to focus on while reading this.
