A Relational Data Model for Uncertain Data
Keywords:Uncertain data, Data model, Relational database
There are many traditional data models developed for the purpose of storing, managing, and manipulating certain data. However, data comes from different sources which may also include data which is imprecise or inexact. For an application which generates uncertain data, its storage, management, and manipulation becomes equally important as for the certain data. This study presents a relational data model for storing, managing, and manipulating uncertain data with certain data. The data model is analyzed using SQL queries to ensure the completeness of the model. Furthermore, a comparative analysis of proposed data model with existing data models is also presented.
