TAILIEUCHUNG - Making Database Systems Usable

Two other papers focus specifically on building sovereign debt datasets. Jeanne and Guscina (2006) collected data on emerging economy public debt, with details on the jurisdiction of issuance, maturity, currency, and indexation. The data cover 19 emerging economies during 1980–2002 and were compiled mainly from official publications, supplemented by information from questionnaires to country authorities and IMF data. Cowan, Levy-Yeyati, Panizza, and Sturzenegger (2006) constructed a database to highlight trends in the level and composition of public debt in the Americas, while analyzing debt dollarization. Their data cover 29 countries in the region, and for comparison, three economies from. | Making Database Systems Usable H. V.

We assert that the usability of a database is as important as its capability. In this paper we study why database systems today are so difficult to use. We identify a set of five pain points and propose a research agenda to address these. In particular we introduce a presentation data model and recommend direct data manipulation with a schema later-approach. We also stress the importance of provenance and of consistency across presentation models. Categories and Subject Descriptors H.

Today we are able to efficiently process ever larger numbers of ever more complex queries on ever more humongous data sets. As a field we can be justifiably proud of what we have accomplished. However when we see how information is created accessed and shared today database technology remains only a bit player much of the data in the world today remains outside database systems. Even worse in the places where Supported in part by NSF grant IIS 0438909 and NIH grants R01 LM008106 and U54 DA021519.
