This Turing Award talk intermixes a bicycle ride across America during the summer of 1988 with the design, construction and commercialization of Postgres during the late 80’s and early ‘90’s. Striking parallels are observed, leading to a discussion of what it takes to build a new DBMS. Also, indicated are the roles that perseverance and serendipity played in both endeavors. Read More

The abundance of data available these days demands techniques to process and manage data in an effective manner. Clusters are extracted groups of data object. Finding and using clusters are popular techniques for unsupervised discovery of hidden structures from complex datasets which are revealed by a large size of data. Since clusters are used in a variety of application domains,... Read More

The Oracle Database In-Memory Option allows Oracle to function as the industry-first dual-format in-memory database. Row formats are ideal for OLTP workloads which typically use indexes to limit their data access to a small set of rows, while column formats are better suited for Analytic operations which typically examine a small number of columns from a large number of rows....

With the end of the civil war between Hadoop and traditional database, customers have data in both: using the most appropriate tool for whichever kind of data it is. The natural result of this is a need for a unified query infrastructure to provide a simple interface to request reports that may draw on data in, for example, Oracle, MongoDB,... Read More

Multi-tenancy and resource sharing are essential to make a Relational Database-as-a-Service (DaaS), such as Azure SQL Database, cost-effective. However, one major consequence of resource sharing is that the performance of one tenant's workload can be significantly affected by the resource demands of co-located tenants. In the SQLVM project at Microsoft Research, our approach to performance isolation in a DaaS is... Read More
