Data Marts: Plan Big, Build Small

Information Systems Management, 1998
Abstract Data marts provide many decision support capabilities without incurring the cost and complexity associated with an enterprise data warehouse. With proper planning, they can be gradually consolidated to create a centralized warehouse that meets business needs and leverages improved technologies.

Effective OLAP Mining of Evolving Data Marts

11th International Database Engineering and Applications Symposium (IDEAS 2007), 2007
Organizations have been used decisions support systems to help them to understand and to predict interesting business opportunities over their huge databases also known as data marts. OLAP tools have been used widely for retrieving information in a summarized way (cube-like) by employing customized cubing methods.

Data modeling for improving performance of data mart

IEMC '98 Proceedings. International Conference on Engineering and Technology Management. Pioneering New Technologies: Management Issues and Challenges in the Third Millennium (Cat. No.98CH36266), 2002
Data warehouse is a technology of potentially enormous worth to an enterprise. It is defined as a subject oriented, integrated, time-variant, and nonvolatile collection of data in support of the management decision-making process. Data mart is basically another form of a data warehouse, but it is a decentralized subset of data found in the data ...

Incremental updates using Data Warehouse versus Data Marts

2018 4th International Conference for Convergence in Technology (I2CT), 2018
Organization performs analytical processing on warehouse data and generates results using OLAP queries. Query result retrieval time is high as it traverses through huge data. With periodic warehouse refresh, frequent OLAP queries fired next time may require incremental update.

Toward building a comprehensive data mart

SPIE Proceedings, 2004
To uncover new relationships or patterns one must first build a corpus of data or what some call a data mart. How can we make sure we have collected all the pertinent data and have maximized coverage? There are hundreds of search engines that are available for use on the Internet today. Which one is best?

Modeling AADL Data Communications with UML MARTE

2008
The emerging OMG UML Profile for Modeling and Analysis of Real-Time Embedded systems (MARTE) aims, amongst other things, at providing a referential Time Model subprofile where semantic issues can be explicitly and formally described. As a full-size exercise we deal here with the modeling of immediate and delayed data communications in AADL.

Realizing the Power of Data Marts

IEEE Power and Energy Magazine, 2007
This paper presents a water and power utility taps nonoperational data with a power system data mart project. Power utilities have enjoyed predictable success at boosting system efficiency, reducing outages, and managing assets more effectively by investing in substation automation projects.

Approximate queries on distributed data marts

International Journal of Information and Decision Sciences, 2009
The global business deals with a large amount of business data that are stored in potentially hundreds of distributed systems. It is challenging to allow end-users issue online analytical processing (OLAP) queries to retrieve suitable information through a worldwide network. This article presents the idea of using statistical methods to model federated

Establishment of Water Environmental Data Mart

2009 3rd International Conference on Bioinformatics and Biomedical Engineering, 2009
The concepts of data warehouse, data mart, on-line analytical processing (OLAP) are introduced into the domain of environmental decision support system. A water environmental data mart (WEDM) is developed with a city's water environmental operation database as data source, and with star schema as data framework. Two main parts are included in WEDM, the
