Which Of The Following Is Not A NoSQL Database
Which Of The Following Is Not A NoSQL Database – NoSQL database is all So, know as a SQL. And, they are non-tabular databases that store data differently than a relational table. However, they have multiple types of a data model: key-value, wide column, graph, and document. So, they provide flexible schemas and scale quickly with a large amount of data and a high user load.
What is a NoSQL Database?
which of the following is not a nosql data base – Therefore, people use the term of NoSQL database, which is usually use to refer to any non-relational database. So, some tod NoSQL stands for non SQL. Meanwhile, others say it stands for not only SQL. Similarly, most agree that NoSQL databases store data in a format other than a relational table.
Different types of NoSQL Data Store
As I say, types of the data model. Here we will discuss in detail the format.
Key-Value Store
Therefore, people use the term of NoSQL database, which is usually use to refer to any non-relational database. So, some tod NoSQL stands for non SQL. Meanwhile, others say it stands for not only SQL. Similarly, most agree that NoSQL databases store data in a format other than a relational table. And, the key-value store maintains data as pair containing index key and value. Key-value store demand value by using index key. In other words, to say it resembles a relational database, but each table has only two columns.
However, some stores will be allowed to join to help you scan through. But if there are composite joins. They may not be suitable options.
Multiple KV Stores are available, differing mainly in their adaption of the CAP theorem and their memory v/s storage usage configurations. KV stores has fast query performance, and they are best suited for applications that need content caching. For instance, a gaming website constantly updates the top 10 scores & players.
Document Store
Document Store is an addition of easy of key value. However, values are store in the structured document like XML o JSON. Document store that makes it easy to map objects in object-oriented software.
The document database is schema-free. And, you don’t have to describe a schema early and adhere to it. But, it also allows us to store complex data into document formats (JSON, XML, etc.). However, document databases is does not support relations. Every document is store in a document store that is independent and has no relational integrity.
Document stores can be uses for all use cases of a Key-Value store database. Still, it has additional advantages, such as it does not have any limitation of querying just by the critical value. However, the querying qualities within a document. Therefore, data in the document store can be in a different format. For instance, A product review website where zero or many users can review each product, and each review can be supposed on by other users, and it can be liked or disliked by zero to many users.
Wide colum Store
It takes a hybrid approach mixing declaration feature game of relational database with key-value pair that is a variable schema of key-value store. However, it stores data table as a section of columns of data rather than as rows of data
Graph Data
Firstly, graph databases have some precise resolve to store graph-oriented data structures. However, the graph database is the only who provide any storage system index-free adjacency. That means that every node contains a direct pointer. So, its adjacent element and no index lookups are compulsory. Secondly, as the number of nodes increases, the cost of a hop will be the same.
Graph databases are optimize for traversing through connected data. For instance, navigating a list of contacts on your social network will determine the degree of connections. In addition, graph databases come with an elastic data model. So, it means you don’t need to find types of edges and vertical.
