Relational database-as-a-service (DaaS) providers need to rely on multi-tenancy and resource sharing among tenants, since statically reserving resources for a tenant is not cost effective. A major consequence of resource sharing is that the performan

Multi-tenancy and resource sharing are essential to make a Database-as-a-Service (DaaS) 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

Memory is a crucial resource in relational databases (RDBMSs). When there is insufficient memory, RDBMSs are forced to use slower media such as SSDs or HDDs, which can significantly degrade workload performance. Cloud database services are deployed i

Queries that scan a B-Tree index can suffer significant I/O performance degradation due to index fragmentation. The task of determining if an index should be defragmented is challenging for database administrators (DBAs) since today's database engine

Sharing resources of a single database server among multiple tenants is common in multi-tenant Database-as-a-Service providers, such as Microsoft SQL Azure. Multi-tenancy enables cost reduction for the cloud service provider which it can pass on as s

Retail is increasingly moving online. There are only a few big e-tailers but there is a long tail of small-sized e-tailers. The big e-tailers are able to collect significant data on user activities at their websites. They use these assets to derive i

Decision support queries that scan large indexes can suffer significant degradation in I/O performance due to index fragmentation. DBAs rely on rules of thumb that use index size and fragmentation information to accomplish the task of deciding which

Relational database management systems (RDBMSs) today serve as the backend for many real-world data intensive applications. Database developers use data access APIs such as ADO.NET to execute SQL queries and access data. While modern program analysis
