Database Offloading For Search Based Applications


tutorial at
12th International Conference on Business Information Systems (BIS 2009)

Poznan, Poland



Databases offer precise, controlled access to data, but they do not offer the easy-to-use search capabilities that most knowledge workers manipulate daily on sites such as Google. One solution to this information bottleneck is to let search engines support the brunt of the work, by offloading information from the databases using search engine technology.

Many business applications such as search, report generation and data analysis can be performed more efficiently on the replicated data without involving the native database technology, e.g. transactions. Offloaded databases, retaining some of their structure, can be recombined, mashed together, to create disposable databases, while the primary data is safe in the original database.

This tutorial will examine the techniques involved in offloading databases for search based applications. A case study of an actual case of database offloading will be presented.

Structure of the tutorial:

  • comparative difference of data base and search engine technology

  • data structures, indexes, query languages

  • administration of db and ir systems

  • maintaining structure and data models in search engines

  • database connectors

  • performance comparisons

  • affordances of search

  • faceted search

  • mashups, disposable databases

  • case study (GEFCO)
