Okay, so on your demand we are back with the yet another cool difference series for our readers. In our today’s series, we are going to learn about the basic difference between the SQL and NoSQL, again to related but still, very different terms. Both the concepts can be easily comparable thus it will be fun to understand their basic difference. So, let’s start with some basics first.
SQL or can be abbreviated as a structured query language, it is database management language which involves in storing, retrieving and locating the data files. SQL saves data in the shape of the table that’s because it is a relational database system. It has queries instead of commands to access, retrieve and manipulate the data files. These queries are standardized for the project so it’s easy to move from the one project to another.
For example, the SELECT command is used to select the particular data from the predetermined table. It is used to locate the record which needs any action. So, the selected record will be then stored in the result set and further required action is performed on it.
There are plenty of different SQL commands available which makes the interaction with the other database easy and in a way handles our database for us. SQL is developed to make complex databases which have the capacity to handle a larger sum of data. The popular SQL database management systems are; MySQL, Oracle, SQLite, PostgreSQL.
As the name suggests, NoSQL is something which is the total opposite to the SQL. NoSQL is a nonrelational database management system. It is mainly used to create the database for the low budget and small companies with the less data work. It is more flexible than the SQL as data is stored in it in the form of graphs, charts, objects which gives room for new data entries to accommodate easily in the database.
However, some database researchers think this flexibility feature as a misguiding feature. It becomes a problem when the data on the cross-platform databases are managed.
Moreover, this doesn’t have any standardization format to migrate the database. This is a very crucial issue of the NoSQL which needs to solved pretty soon. It also requires community which can solve the problems on the basis of the proper documentation. The popular NoSQL database management systems are; MongoDB, BigTable, Redis, RavenDB, Cassandra.
Difference Between SQL & NoSQL
The basic difference between both database management systems is the relational concept. SQL is a purely relational database management system whereas NoSQL is a clean nonrelational database system.
SQL database system needs to develop the schema in advance and all the data is stored as per the schema. On the other hand, NoSQL already has its dynamic schema ready.
In SQL, all the data is stored in the form of tabular. But, NoSQL gives more options to the users to store data in the form of objects, graphs, key-value pairs, etc.,
SQL has standardized syntax commands for the query of the database. Whereas NoSQL has no standardized query format to locate the data on cross platforms.
SQL database is designed to store the huge and complexed database, however, NoSQL is formatted to handle the fewer data and in the low budget. SQL is suitable for big companies and NoSQL for the smaller ones.
So, here we are done with the yet another interesting difference. If you like it and want to read more articles in this series, then show your appreciation by sharing and liking the post.
