Selecting the database for modern applications has been a big challenge for some. Particularly after the arrival of relational DBMSs like PostgreSQL, MS SQL, and MySQL that have been dominant in the recent past.
Out of this, MySQL has consistently been a go-to option for many companies that are strictly searching for a relational database. However, with growing variety and massive volumes of data, the non-relational databases like MongoDB have risen as a solution for many enterprises’ need for fluid data.
The advent of the new non-relational database has given rise to the competition among MongoDB vs MySQL. This competition makes it difficult for entrepreneurs to select between the two. Here we will compare both the databases based on several factors that will give you insights about which database is better. Additionally, we will reveal when to use MongoDB or MySQL.
What is MySQL?
As an open source RDBMS, (relational database management system), MySQL has increased popularity throughout the years. It was developed by MySQL AB and now owned by Oracle Corporation. Based on requirements, the users can pre-define the database schema and establish rules, capable of governing the connection between relevant fields in the tables.
MySQL, like other relational DBMSs, uses SQL (structured query language) to get access to database and keeps the data stored in tables. For rolling out any change in the schema, a migration procedure is essential, that can reduce the performance of the application significantly. It can likewise take the database to the offline mode.
What is MongoDB?
MongoDB was developed by MongoDB, Inc and it is a well known non-relational database. Data is stored in this type of DBMS as documents in a form called BSON (a type of binary representation). The query access, the MongoDB query language is used to store the related data. The fields may be different for each document, and you should not declare the document structure to the systems. These documents are self-explanatory in nature.

If you have to add another field to the document, you can create it, without rolling out any change to other documents present in the collection. The central system catalog doesn’t require any update and you need not take the system to the offline mode. You can use schema validation optionally to enforce the control of data over each one of the collections. The document data model of MongoDB maps objects in the application mode naturally. Subsequently, developers find it simple to master and use. The users can represent the hierarchical associations to the store arrays flawlessly, with other complicated structures.
MongoDB vs MySQL:
Both MongoDB and MySQL have gained popularity as open-source database software. However, each of them is suitable for a particular situation. Let us see the difference between those two according to different aspects.
1. Database Structure-
In MySQL, the data value is stored in the tables by the MySQL database structure where SQL is used to access them. Schema is used to define the database structure. The prime requirement of the schema is that the rows have a similar structure inside the table. It also requires its values to be represented by specific data types.
Though, in the MongoDB database, the data is stored in JSON-like documents that come in varied structures. To increase the query speed, it stores the related data sets together. These sets are then accessed by using the MongoDB query language.
The database is schema-free, which implies that the mobile application developers don’t need to define any document structures for creating the documents.
