What is nosql used for?

NoSQL, which stand for "not only SQL ," is an alternative to traditional relational databases in which data is placed in tables and data schema is carefully designed before the database is built. NoSQL databases are especially useful for working with large sets of distributed data.
Next, what is NoSQL and how is it used?
NoSQL is a non-relational database that stores and accesses data using key-values. Instead of storing data in rows and columns like a traditional database, a NoSQL DBMS stores each item individually with a unique key.
Just so, why is NoSQL better than RDBMS? Data output performance is better in NoSQL due to the support caching in system memory. Separate infrastructure is not needed and hence this makes the developers tally the data easily. Whereas in RDBMS, separate infrastructure is needed due to the absence of support caching. This makes the data tally difficult.
And, what are the disadvantages of NoSQL?
Disadvantages of NoSQL include lack of consistency as well as insufficient support for relational data. "Queries require re-architecting and recoding of existing products," according to one source.
Thereof, why do you need NoSQL for the Internet of things?
NoSQL databases are also more scalable, offering flexibility in data models. You can have a structure similar to SQL with wide tables, or you might choose to go with a document-oriented database, key-value database, or graph database. Time series databases are one of the more obvious choices for Internet of Things applications specifically.

How does slashdb work as a nosql database?

SlashDB preserves and extends the underlying database permission mechanisms and can be easily integrated with single-sign-on and user-entitlement systems.

What makes a nosql database a non-relational database?

NoSQL uses the BASE system (basically available, soft-state, eventually consistent). Non-relational databases forgo the table form of rows and columns relational databases use in favor of specialized frameworks to store data, which can be accessed by special query APIs. Persistence is an important element in these databases.
