 Explain  NoSQL= NoSQL is a category of database engines that do not support the SQL (Structured Query Language) in order to achieve performance or reliability features that are incompatible with the flexibility of SQL. - http://stackoverflow.com/questions/4154635/what-is-nosql-what-is-purpose-of-nosql-where-can-i-get-sufficient-material-on-n  Non-relational database= a non-relational database developed by Damien Katz, now the chief technology officer for Couchbase. The company claims that Mobile Couchbase is the first non-relational, or NoSQL database, built for iOS. - http://stackoverflow.com/questions/202819/what-is-an-example-of-a-non-relational-database-where-how-are-they-used  Explain the advantages of CouchDB's noSQL - CouchDB and noSQL architecture has a number of advantages that make it attractive to iPhone applications developers, the company asserts. - CouchDB= Efficient use of working memory, Amount of storage space (takes up relatively minimal, under 20 megabytes download size limit imposed by many people CouchDB's NoSQL has advantages such as its synchronization capabilities with minimal coding. Data can be automatically synchronized across a network. The app can store data created on the phone itself, all the while also synchronizing the same data with a cloud service or a data center. The storage space taken up by CouchDB's NoSQL has efficient use of working memory. When it is embed in an app, it can still keep the app to be under the 20 mb download limit, and doesn't drain the battery.

Describe NoSQL and its purpose. NoSQL is a highly scalable and reliable non-relational databases designed to maintain high performance and to be highly cost efficient for workloads of any scale, from the smallest to the largest internet-scale applications. It is also used to build a new kind of database for "unstructured" information that comes spilling off the Internet with each passing second. It is capable of handling large amounts of data du to the fact that they use flash storage rather than traditional spinning disks. These solid-state drives can provide single-digit millisecond response times. Explain how it is used differently than MySQL. MySQL database is a relational database that stores data in neat rows and columns, and it's designed to run on a single machine, while NoSQL database can store data in a more flexible way and is designed to scale across a very large number of machines. "SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle." http://stackoverflow.com/questions/2559411/sql-mysql-vs-nosql-couchdb
