2015 Lecture Notes in Computer Science  
As a new way to interact with statistical Linked Data we define comon OLAP operations on data cubes modelled in RDF and show how a nested set of OLAP operations lead to an OLAP query.  ...  Online Analytical Processing (OLAP) promises an interface to analyse Linked Data containing statistics going beyond other interaction paradigms such as follow-your-nose browsers, faceted-search interfaces  ...  The current work presents a new way to interact with statistical Linked Data: -We define comon OLAP operations on data cubes as Linked Data reusing QB and show how a nested set of OLAP operations lead  ...

2016 2016 IEEE 32nd International Conference on Data Engineering (ICDE)  
Without requiring any RDF, QB(4OLAP), or SPARQL skills, it allows semi-automatic transformation of a QB data set into a QB4OLAP one via enrichment with QB4OLAP semantics, exploration of the enriched schema  ...  The RDF Data Cube (QB) vocabulary, the current standard for statistical data publishing, however, lacks key MD concepts such as dimension hierarchies and aggregate functions.  ...  Statistical data have traditionally been accessed and analyzed by means of OLAP [1] .  ...

OLAP on Information Networks: A New Framework for Dealing with Bibliographic Data [chapter]

Wararat Jakawat, Cécile Favre, Sabine Loudcher
2014 Advances in Intelligent Systems and Computing  
For several years, OLAP is also used to analyze and visualize more complex data. Now, many data sets of interest can be described as a linked collection of interrelated objects.  ...  In the context of decision making, data warehouses support OLAP technology and they have been very useful for efficient analysis onto structured data.  ...  Kampgem et al. presented a mapping from linked data to data cube [8] . They integrated statistic linked data into format for loading into OLAP systems.  ...

Data mining: concepts and techniques

2012 ChoiceReviews  
Data Warehouse: Mostly read only queries, operate on HUGE volumes of data, queries are quite complex. 3 Main reasons: 1.  ...  OLAP systems access historical data and not current volatile data while OLTP systems access current up-to-date data and do not need historical data.  ...  Example: Sales data may be on RDB, Customer information on Flat files, etc. • Time Variant: Data stored may not be current but varies with time and data have an element of time.  ...
