Can we have indexes in NoSQL database?

Can we have indexes in NoSQL database?

Indexing Structures for NoSQL Databases. Indexing is the process of associating a key with the location of a corresponding data record. There are many indexing data structures used in NoSQL databases.

Why NoSQL databases do not follow ACID properties?

Firstly ACID is not to be considered as a single entity (as done by most). ACID is an abbreviation i.e. Atomicity, Consistency, Isolation, Durability. Even though many NoSQL databases do no comply with ACID properties, many do support a part of that, AID mostly, compromising Consistency for Performance.

Do all NoSQL systems need indexes?

CouchDB and MongoDB definitely yes. I mentioned that in my book: NoSQL is, however, too fragmented to give a definite “yes, all NoSQL systems need indexes”, I believe. Most systems require and provide indexes but not at level most SQL databases do.

What are the different types of NoSQL databases?

Types of NoSQL databases include pure document databases, key-value stores, wide-column databases, and graph databases. NoSQL databases are built from the ground up to store and process vast amounts of data at scale and support a growing number of modern businesses.

Does a NoSQL database slow down or speed up development?

This slows down or stops development, not only because it is a manual, time-consuming process, but it also impacts other applications and services. By contrast, a NoSQL database fully supports agile development and does not statically define how the data must be modeled.

What is the difference between NoSQL and agile?

By contrast, a NoSQL database fully supports agile development and does not statically define how the data must be modeled. Instead, NoSQL defers to the applications and services, and thus to the developers as to how data should be modeled. With NoSQL, the data model is defined by the application model.
