Databases

NoSQL databases have an edge over the conventional relational DBMS.
Some of them are:
1) One doesn't need to know the structure of data beforehand as it is with the RDBMS (requires a fixed schema). The format/data model can be changed anytime without affecting the application driven by the database.
2) Using Hadoop implementations in conjugation with NoSQL database, data could be stored across 1000s of servers( volumes of data which even the biggest RDBMS can't handle). This data can be processed and retrieved really fast.
3) NoSQL databases use clusters of cheap commodity servers to manage the exploding data and transaction volumes, while RDBMS tends to rely on expensive proprietary servers and storage systems.

Hello,
The DataBase Administrator actually is direct connection between company's information and its customer. As its name suggest, that Administrator is a person who manage the Data from the bases. You are responsible to transmit the data to customer in a secured way, and that too with unauthorized access. DBAs sometimes work with an organizations management to understand the company's data needs and to plan the goals of the database. Mostly, the DBAs who are working under the firms are done with Management Information System. Some large corporation prefers those who pursued their Bachelors and Masters in computer related field along with MIS certification. Database administrators need an understanding of database languages, the most common of which is Structured Query Language, commonly called, SQL. Most database systems use some variation of SQL, and a DBA will need to become familiar with whichever programming language the firm uses. These are some of the required set of skills that you must have to poses.

There are major job prospects for NewSQL Databases.

Hi,
In Data warehousing and Analytics, lack of standard certifications have made it very hard for recruiters to identify "A" league professionals from impostors. When the topic of certification comes, there are basically two questions, why to get certified and how and what to get certified. I would first answer what and then answer why.
Irrespective of technology, The Data Warehousing Institute (TDWI) has been a provider of Certified Business Intelligence Professional (CBIP) certification where professionals can choose their core skills and appear for the exam that suits the same. The flip side that professionals see to it is that it's not associated with any product in specific and just theory can be good at Architect profile but at career levels where professionals need to implement solutions this might not be able to impress recruiters with this certifications.
Being a Microsoft patron, I would discuss about certifications related to MS BI. Microsoft has recently introduced two certifications for Data Warehousing and Business Intelligence.
All the best.

NewSQL is a class of modern relational database management systems that seek to provide the same scalable performance of NoSQL systems for online transaction processing (OLTP) read-write workloads while still maintaining the ACID guarantees of a traditional database system.
Currently, there aren't many institutes which cover this course. However, there are various online tutorials and forums, wherein a student can learn about it. To learn this course, one has to be completely aware of general database structure, which involves Relational Database Management Systems (RDBMS), Database Queries and interfacing a database to other languages and application.
NewSQL is an emerging field with an optimized SQL structure. Soon, it will find enough job opportunities as companies begin migrating their existing framework into the modern NewSQL structure.
I hope this answers the question.
