A Survey on Array Databases

PhD Qualifying Examination


Title: "A Survey on Array Databases"

by

Mr. Guo CHEN


Abstract:

While scientific investigation has been one of the most important sources of 
big data, the most ubiquitous representation of scientific data, array, is 
still far from being studied from the perspective of database modeling and 
processing. There is insufficient support of incorporating arrays into the 
current database technology. Therefore, scientists in many disciplines, such as 
earth science and meteorology, mainly rely on their own ad-hoc approaches to 
manipulate the datasets.

To overcome this, large multi-dimensional arrays as first-class database 
citizens have been researched. The formalism and query languages tailored for 
array databases have been proposed. Some prototypes are also implemented and in 
practical use.

In this report, we first present the motivation of array processing systems, 
followed by analysing array database model from a top-down approach: 
conceptual, logical and physical layer. Then the differences between array 
database model and other relevant models are discussed. Finally, the potential 
research issues in this burgeoning research area conclude this report.
