Is SQL required for MongoDB?

MongoDB does not use SQL as a query language. I would consider the Google App Engine Data Store NoSQL, and it uses a SQL-like query language GQL. The main reason we went the way we did with the query language – representing queries as JSON – was to normalize the data we are storing with the query mechanism.

Is it necessary to learn MySQL before MongoDB?

No it is not required to learn before the other. They are both Database engines that provide methods for storing and retrieving structured data. Note that MySQL and other SQL variants are used in dramatically more places that MongoDB.

Which is easy SQL or MongoDB?

MongoDB is more fast and scalable in comparison to the SQL server. MongoDB doesn’t support JOIN and Global transactions but the SQL server supports it. MongoDB supports a big amount of data but the MS SQL server doesn’t. MongoDB support Agile practices but MS SQL server doesn’t support it.

What is required to learn MongoDB?

Since you are planning to learn MongoDB you should have following prerequisites: MySQL or any other database experience. Experience with Java programming Language. Basic Understanding of Big Data Platforms.

Is SQL injection possible in MongoDB?

SQL databases are the most vulnerable to this type of attack, but external injection is also possible in NoSQL DBMs such as MongoDB. In most cases, external injections happen as a result of an unsafe concatenation of strings when creating queries.

Which is better MySQL or MongoDB?

MongoDB is faster than MySQL due to its ability to handle large amounts of unstructured data when it comes to speed. It uses slave replication, master replication to process vast amounts of unstructured data and offers the freedom to use multiple data types that are better than the rigidity of MySQL.

Can MongoDB replace SQL Server?

MongoDB is a cross-platform document-oriented and a non relational (i.e., NoSQL) database program. It is an open-source document database, that stores the data in the form of key-value pairs….Difference between MS SQL Server and MongoDB :

S.NO.	MS SQL server	Mongodb
9.	MS SQL Server does not supports Map Reduce method.	MongoDB supports Map Reduce method.

Can MongoDB replace MySQL?

MySQL, MS SQL Oracle, and Server are nearly synonymous with RDBMS, but MongoDB is a cross-platform document-oriented and NoSQL database. At times, it can be a wise decision to replace MySQL with MongoDB. It is a nimble database that allows fast changes of the cognitive framework when apps evolve.

Is NoSQL safer than SQL?

With the emergence of new databases and query techniques, the old attack methods become obsolete and new ones emerge. For example, most NoSQL databases do not use SQL and instead use the JavaScript Object Notation (JSON) query language and an HTTP API. However, NoSQL definitely does not imply zero risk.
