Creating and Querying Databases with NoSQL and SQL

NoSQL (Non-SQL or Not-only-SQL) databases are increasing in popularity due to the growth of data as they can store non-relational data on a super large scale, and can solve problems regular databases can't handle. They are widely used in Big data operations. Their main advantage is the ability to handle large data sets  effectively  as well as scalability and flexibility issues for modern applications. There are different categories of NoSQL  databases and they are used in social media such as with Facebook  and search like Google and in other types of sectors like Health, Aviation,Education  and other areas.

In this course  we will Use the CouchDB NoSQL database. We will create a database,load data and  query a database. Learn techniques such as querying with JavaScript, working with nested data, and creating views.You will learn how to query a database without  SQL by using JavaScript Map and Reduce functions Using the couchDB database you will learn how to insert data into the database using Key -Value pairs where every data key will have a corresponding value. Security and integrity of a database is very important  .

The volume of data available is huge and increasing daily. Structured Query Language -SQL (pronounced as sequel) is the standard language used to communicate and interact with data stored in relational management database systems like Microsoft  SQL Server Oracle, PostgreSQL,MySQL etc.

Different database management systems have their own proprietary  version of the SQL language  but they all conform to using some commands in SQL the same way.   Microsoft SQL Server's version of SQL is known as Transact-SQL  (T-SQL). In this course you will learn the basics of the SQL language and Transact-SQL since  both use certain commands in the same way. We will learn to create a database,table and how to insert data into a database table as well as querying it.
