BIB-VERSION:: CS-TR-v2.0 ID:: UCB//S2K-93-29 ENTRY:: February 25, 1994 TITLE:: Tioga: Providing Data Management Support for Scientific Visualization Applications DATE:: AUTHOR:: Stonebraker, Michael AUTHOR:: Chen, Jolly AUTHOR:: Nathan, Nobuko AUTHOR:: Paxson, Caroline AUTHOR:: Wu, Jiang PAGES:: 14 ABSTRACT:: We present a user interface paradigm for database management systems that is motivated by scientific visualization applications. Our graphical user interface includes a "boxes and arrows" notation for database access and a flight simulator model of movement through information space. We also provide means to specify a hierarchy of abstracts of data of different types and resolutions, so that a "zoom" capability can be supported. The underlying DBMS support for this system is described and includes the compilation of query plans into megaplans, new algorithms for data buffering, and provisions for a guaranteed rate of data delivery. The current state of the Tioga implementation is also described. RETRIEVAL:: postscript (in all.ps) END:: UCB//S2K-93-29
