What is NoSQL database design?

NoSQL databases are designed to break away from the rows and columns of the relational database model. Another important design driver is the types of data access that need to be supported. Some use cases require access via a query language and others require access by one or more applications.

What type of modeling techniques are available to NoSQL databases?

There are a five general techniques for NoSQL data modeling:

  • Enumerable Keys. For the most part, unordered key values are very useful, since entries can be partitioned over several dedicated servers by just hashing the key.
  • Dimensionality Reduction.
  • Index Table.
  • Composite Key Index.
  • Inverted Search – Direct Aggregation.

Is NoSQL better for Microservices?

  • Column-based Store- Each storage block contains data from only one column,{Example- HBase,Cassandra}
