Relational versus non-relational database systems for data warehousing

Carlos Ordonez, Il-Yeol Song, Carlos Garcia-Alvarado
2010 Proceedings of the ACM 13th international workshop on Data warehousing and OLAP - DOLAP '10  
With that motivation in mind, this panel will compare pros and cons of each technology for data warehousing and will identify research issues, considering practical aspects like ease of use, programming  ...  flexibility and cost; as well as technical aspects like data modeling, storage, hardware, scalability, query processing, fault tolerance and data mining.  ...  DOLAP'10, October 30, 2010, Toronto, Ontario, Canada. ACM 978-1-4503-0383-5/10/10. streams, column stores, keyword search, content-based image retrieval, and MapReduce, among others).  ...

Towards readable layouts for modeling data warehouses

Jesús Pardillo, Florian Mansmann
2010 Proceedings of the ACM 13th international workshop on Data warehousing and OLAP - DOLAP '10  
For each one, surveyed as well as alternative layouts were evaluated against a set of aesthetics and efficiency measures.  ...  Data warehouses are large-scale databases that are usually managed by means of diagram-based conceptual models. However, the complexity of those models often imposes significant design challenges.  ...  DOLAP'10, October 30, 2010, Toronto, Ontario, Canada.

Context-aware generalization for cube measures

Yoann Pitarch, Cécile Favre, Anne Laurent, Pascal Poncelet
2010 Proceedings of the ACM 13th international workshop on Data warehousing and OLAP - DOLAP '10  
In this paper, we tackle this issue and we show that measure generalizations often depend on a context.  ...  Hierarchies are crucial for analysis in data warehouses. But they can hardly be defined on measure attributes.  ...  To copy otherwise, to republish, to post on servers or to redistribute to lists, requires prior specific permission and/or a fee.

Using ontologies to discover fact IDs

Alberto Abelló, Oscar Romero
2010 Proceedings of the ACM 13th international workshop on Data warehousing and OLAP - DOLAP '10  
with data.  ...  Many works have been introduced in the literature for discovering meaningful IDs, but all of them work at the logical or data level and they share some constraints inherent to the kind of approach.  ...  DOLAP'10, October 30, 2010, Toronto, Ontario, Canada.
