Dimensional Modeling Using Star Schema for Data Warehouse Creation

Mudasir M Kirmani
2017 Oriental journal of computer science and technology  
Dimensional Modelling is one of the popular techniques for databases that are designed keeping in mind the queries from end-user in a data warehouse.  ...  In this paper the focus has been on Star Schema, which basically comprises of Fact table and Dimension tables.  ...  This type of the schema does represent the logical structure of a database. This overall structure can be expressed graphically by an E-R diagram.  ...

A Design Comparison: Data Warehouse Schema versus Conventional Relational Database Schema

Abdulrahman Yusuf
2016 International Conference on Computing Research and Innovations  
This conceptual paper discusses traditional database schema design and that of data warehouse schema architectural designs strategies that could be a guiding principles for both learners and beginners  ...  Initially, relational database is for both operational and decision support system, as the information society experiences exponential growth in the amount of data/information to be stored in a database  ...   The essential structure of data warehouse is the present of some feature of time (example days, month, and year).  ...

Comparing the understandability of alternative data warehouse schemas: An empirical study

David Schuff, Karen Corral, Ozgur Turetken
2011 Decision Support Systems  
Further, the relational schema actually led to slightly better results for a schema augmentation task. We discuss the implications of these findings for data warehouse design and future research.  ...  It also makes it easier for users to suggest changes to its structure and content.  ...  One example is during the systems analysis and design process, where verifying the validity of a database schema is an essential step in application development.  ...

The INCOME Approach for Conceptual Modelling and Prototyping of Information Systems

Georg Lausen, Tibor Németh, Andreas Oberweis, Frank Schönthaler, Wolffried Stucky
1989 International Conference on Advanced Information Systems Engineering  
INCOME supports the specification and prototyping of all static and dynamic system aspects which are regarded to be relevant for the design.  ...  Petri nets with different interpretations are used as uniform specification framework for object structures and system behaviour.  ...  An assumption of schema part modelling for a certain object flow 0 is that all schema parts and local structures required for the object flows of the lower level diagram are present.  ...

Exploring the Visualization of Schemas for Aggregate-Oriented NoSQL Databases

Alberto Hernández Chillón, Severino Feliciano Morales, Diego Sevilla, Jesús García Molina
2017 International Conference on Conceptual Modeling  
In this article we focus on the requisites for the visualization of schemas for aggregate-oriented NoSQL Databases. Schema diagrams have proven useful in designing and understanding databases.  ...  Being schemaless, these databases provide a greater flexibility, as data with different structure can be stored for the same entity type, which in turn eases data evolution.  ...  Visualizing database schemas in form of diagrams is useful both to designers and developers.  ...
