A hybrid data structure for dense keys in in-memory database systems
This thesis presents a data structure which performs well for in-memory indexing of keys that are unevenly distributed into clusters with a high density of keys. This pattern is prevalent, for example, in systems that use tables with keys where one field is auto-incremented. These types of tables …

An integrated index structure for object-oriented and spatio-temporal information systems
An index structure is one of the access methods extensively utilized in the data- base area. It defines how access to the data stored in pages on disk is made by permit- ting the retrieval of stored objects through a defined key, that is an attribute of the object. A multi-dimensional (dD) index …

New capabilities for large-scale exploratory data analysis
… exploration engine that employs a light-weight indexing structure along with efficient algorithms to retrieve any-k valid records for arbitrary queries as quickly as possible. (ii) For versioning, we implement and open-source ORPHEUSDB, a dataset version control system that can efficiently track …
