BASE analysis of NoSQL database

NoSQL databases are designed to address performance and scalability requirements of web based application which cannot be addressed by traditional relational databases. Due to their contrast in priorities and architecture to conventional relational databases using SQL, these databases are referred as “NoSQL” databases since they ​incorporate lots of additional features in addition to the features of conventional databases. The relational databases strongly follow the ACID (Atomicity, Consistency, Isolation, and Durability) properties while the NoSQL databases follow BASE (Basically Available, Soft State, Eventual consistency) principles. This survey paper is an analytical study on BASE features of some of NoSQL databases.

Evaluation of Various Database Architectures for Datawarehouses: a Case Study on ETL integrated EHR

EHR (Electronic Health Records) describing the diseases and treatments of patients are normally stored in the hospital locations or regions, where they are created. However, patients may be treated in different hospitals, and therefore, there is a need for integrating health records from different hospitals to enable any hospital to obtain a total overview of a patient's health-history. Two different types of heterogeneity problem have to be solved in order to integrate EHR systems from different hospitals in a consistent way. The first problem is that different hospitals normally do not use a common DBMS (Data Base Management System) system and therefore, the traditional ACID (Atomicity, Consistency, Isolation and Durability) properties are missing across the different hospital locations. The second heterogeneity problem is that there are different incompatible standards on how to make EHR registrations. The objective of this paper is to describe and evaluate different EHR database designs for storing more or less incompatible health records from different hospitals.
