Databases

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.

Hello,
Following are the various courses in databases:
Database Administrator (DBA): Responsible for installing, configuring and maintaining a database management system (DBMS). Often tied to a specific platform such as Oracle, MySQL, DB2, SQL Server and others.
*
Database Developer: Works with generic and proprietary APIs to build applications that interact with DBMSs (also platform specific, as with DBA roles).
*
Database Designer/Database Architect: Researches data requirements for specific applications or users, and designs database structures and application capabilities to match.
*
Data Analyst/Data Scientist: Responsible for analyzing data from multiple disparate sources to discover previously hidden insight, determine meaning behind the data and make business-specific recommendations.
*
Data Mining/Business Intelligence (BI) Specialist: Specialises in dissecting, analyzing and reporting on important data streams, such as customer data, supply chain data, transaction data and histories, and others.
*
Data Warehousing Specialist: Specialises in assembling and analyzing data from multiple operational systems (orders, transactions, supply chain information, customer data and so forth) to establish data history, analyze trends, generate reports and forecasts and support general ad-hoc queries.
There are no basic eligibility criteria for enrolling in a database course. The course duration varies from one institute to another.
A database is used by almost all companies today, either in a raw state or along with any other web application or stand-alone application, and thus this course finds massive job opportunities.

Hi,
Glad to see that you are opting for the right technology at the right time. NoSQL is in high demand because of its structure and design and it goes perfectly with Big Data to quick integration with available API.
Mongo DB, AWS Dynamo DB and Google Cloud, Azure these are some well-known NoSQL services which will rule in the DB world without any doubts. I hope you are getting the scope and career progress in NoSQL. I would further advise getting familiar with basic RDBMS functions and designs which would help you to have a quick understanding of the differences between SQL and NoSQL. You may go through the below link to know more insights of mongodb.
