Notes From IT Guy


Big Data, NoSQL vs Relational Databases.
Big Data is everywhere, requirements for HDFS/Hadoop and NoSQL data bases skyrocketed.Will those replace old slow relational DBs?

Not in near future.

Many NoSQL databases do not support transactions and still at very beginning of their life. As a result common to all startups hiccups limit their use to processing static data.

Absence of common API and ACID properties of transactions (atomicity, consistency, isolation and durability) limits use in financial and banking applications.

NoSQL evolves and will eventually replace Relational DBs, but not tomorrow.
