[postgis-users] Workshop on Array Databases

[Baumann, Peter]

Workshop on Array Databases

co-located with EDBT/ICDT 2011, Uppsala / Sweden
submission deadline: December 31, 2011


Workshop Theme

 From the fundamental collection paradigms known in conceptual modeling - sets, bags, lists, and arrays - it is the array concept which has long been neglected by the database community. However, as sensors are becoming ubiquitous and inexpensive, and as further simulations become large, multi-dimensional arrays are attributed a large share of today's archive spaces. Geoscientific examples include 1-D sensor time series, 2-D satellite imagery, 3-D x/y/t image time series and x/y/z geology data, and 4-D x/y/z/t climate and ocean simulation data. A similar wealth of array data can be found in space, life, and other sciences. Sparse arrays appear in OLAP. In summary, arrays (by practitioners often referred to as raster data) comprise the natural representation of n-dimensional sensor, array, and statistics data. Typically these data come in massive volumes, with Petabyte - in future Exabyte - sizes for single arrays. 

Unleashing this huge data reservoir for online analytics by scientists, industry, government, and citizens represents a major information services challenge. As traditional databases do not support large arays, in today's practice ad-hoc implementations prevail, often done by service providers themselves and centered around some particular data formats. Databases are hardly involved for array management. Many researchers believe, however, that database technology can offer its traditional benefits, such as information integration, flexibility of query language, scalability, and dynamic optimization, on arrays as well. 

Currently no forum is existing which expressly concentrates on array databases. Filling this gap, this workshop will gather experts interested in theory, architecture, applications, standardization, and any other relevant aspect of array services. In the closing panel, foundation will be laid towards a research agenda for this emerging field.


Topics of Interest

Submissions of original research contributions and software demonstrations are invited for all array relevant topics, including - but not limited to - the ones below:
  array theory: algebras and calculi
  query languages for massive array data analytics
  logical and physical optimization
  storage methods
  storage hierarchies
  compression
  array database architectures, including both servers and clients 
  distribution and virtualization
  data quality
  uncertainty
  sensor data
  MOLAP
  applications and standardization, such as in Earth, Space, and Life Sciences
  beyond arrays: meshes and other space-time varying data 
  system demonstrations

This one-day workshop on March 25, 2011 will be co-located with EDBT/ICDT 2011 at Uppsala, Sweden. Workshop participants will have to register for EDBT/ICDT; attendance to all workshops will be included in the overall registration fee.

Publication and IP issues

Papers will be made available in online conference proceedings, possibly hosted within the ACM Digital Library (subject to approval). 
*** To enable conference attendees and the general community to
*** glimpse at the content a bit ahead of the conference, we plan
*** to make the papers electronically available before the
*** conference, on March 10, 2011. 
*** Authors are thus encouraged to make sure the necessary 
*** patent issues are solved and enable publication by this date.
