This work shows how SSL can be extended to pose Skyline queries, present and evaluate alternative algorithms to implement the Skyline operation, and shows how this operation can be combined with other database operations, e.g., join.
CrowdDB: answering queries with crowdsourcing

The design of CrowdDB is described, a major change is that the traditional closed-world assumption for query processing does not hold for human input, and important avenues for future work in the development of crowdsourced query processing systems are outlined.
Shooting Stars in the Sky: An Online Algorithm for Skyline Queries
The state of the art in distributed query processing
- D. Kossmann
- Computer ScienceCSUR
- 1 December 2000
The paper presents the “textbook” architecture for distributed query processing and a series of techniques that are particularly useful for distributed database systems, and discusses different kinds of distributed systems such as client-server, middleware (multitier), and heterogeneous database systems and shows how query processing works in these systems.
“A Web service is a software system designed to support interoperable machine-tomachine interaction over a network. It has an interface described in a machine-processable format (specifically WSDL).…
Optimizing Queries Across Diverse Data Sources
This work presents the design of a query optimizer for Garlic, a middleware system designed to integrate data from a broad range of data sources with very different query capabilities, and describes the design and implementation.
A Performance Evaluation of Alternative Mapping Schemes for Storing XML Data in a Relational Database
This paper studies how XML data can be stored and queried using a standard relational database system and presents alternative mapping schemes to store XML data in a relational database and discusses how XML-QL queries can be translated into SQL queries for every mapping scheme.
Storing and Querying XML Data using an RDMBS
A rotary valve assembly of the "soft seat" type for use in fluid distribution systems such as gas or water and means are provided for applying a controlled torque sufficient to render the valve structure inoperative by hand.
ALEX: An Updatable Adaptive Learned Index
A new learned index called ALEX is presented which addresses practical issues that arise when implementing learned indexes for workloads that contain a mix of point lookups, short range queries, inserts, updates, and deletes and effectively combines the core insights from learned indexes with proven storage and indexing techniques to achieve high performance and low memory footprint.
Orthogonal Security with Cipherbase
The design of the Cipherbase secure hardware and its implementation using FPGAs is presented and how the hardware / software co-design was addressed in the cipherbase system is shown.
