Sagiv is one of the founders of the field of relational database theory, and specifically of dependency theory [David Maier, Alberto O. Mendelzon, Yehoshua Sagiv: Testing Implications of Data Dependencies. ACM Trans. Database Syst. 4(4): 455-469 (1979)] .He also did seminal work in the areas of semi-structured databases [Hector Garcia-Molina, Yannis Papakonstantinou, Dallan Quass, Anand Rajaraman, Yehoshua Sagiv, Jeffrey D. Ullman, Vasilis Vassalos, Jennifer Widom: The TSIMMIS Approach to Mediation: Data Models and Languages. J. Intell. Inf. Syst. 8(2): 117-132 (1997)] and local-as-view data integration [Alon Y. Levy, Alberto O. Mendelzon, Yehoshua Sagiv, Divesh Srivastava: Answering Queries Using Views. PODS 1995: 95-104] .

Currently (2008) he is the most-published author in the ACM Symposium on Principles of Database Systems (with 29 papers published there) [ [http://www.sigmod.org/pods/whostat.html ACM PODS pages] ] .
