Data modeling styles in data warehousing
2014 37th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO), 2014The paper presents a coordinated set of data modeling styles relevant for data warehouse design in the context of relational databases. The scope of presented models covers: a) entity relationship models of existing relational DB sources, b) logical data vault model for integrated enterprise data warehouses as a system of records, c) dimensional fact ...

The Grid allows scientists to design and perform very large-scale experiments that are not possible previously. Many of these experiments produce a large number of data sets and significantly the amount of data being captured, generated, replicated and archived is growing at an astonishing rate.

Time is an essential dimension of our perception of the world and hence an important dimension for the representation of the real and social world in data models. We give an overview of the basics of representing time in data models and representing objects and processes with respect to the temporal dimension.

Proceedings of the 2007 ACM symposium on Applied computing, 2007
As a sub-type of ncRNA genes, micro RNA (miRNA) produces RNA that is implicated in the regulation of gene translation and expression. Human diseases can result from alternation in such non-coding RNA. Building a consolidated miRNA database repository thus becomes a crucial element for miRNA-related research. We have set up a dual objective in our work:

ACM Transactions on Database Systems, 1995
In this article, we present an extended relational algebra with universally or existentially quantified classes as attribute values. The proposed extension can greatly enhance the expressive power of relational systems, and significantly reduce the size of a database, at small additional computational cost.

Proceedings of the 14th International Conference on Computer Systems and Technologies, 2013
In this paper the model PER (Process Entity Relationships) for semantic data modeling is presented, based on process and architectural approach. Terms, symbols and conventions used are explained. The levels of the model were described, and some example models are given.
