As an open source RDBMS, (relational database management system), MySQL has gained extensive popularity over the years. It was originally developed by MySQL AB and now owned by Oracle Corporation. Based on the requirements, the users can pre-define the database schema and establish rules, capable of governing the relationship between relevant fields in the tables.<\/p>\n

<\/p>\n
MySQL, like other relational DBMSs, uses SQL (structured query language) to get access to database and keeps the data stored in tables. For making any change in the schema, a migration procedure is necessary, that can reduce the performance of the application significantly. It can also take the database to the offline mode.<\/p>\n
<\/span>What is MongoDB?<\/span><\/h2>\nMongoDB was developed by MongoDB, Inc and it is a popular non-relational database. Data is stored in this type of DBMS as documents in a form called BSON (a type of binary representation).<\/p>\n

<\/p>\n
For query access, the MongoDB query language is used to store the related data. The fields may be different for each document, and you need not declare the document structure to the systems. These documents are self-explanatory in nature.<\/p>\n
In case you need to add a new field to the document, you can create it, without making any change to the other documents present in the collection. The central system catalog does not require any update and you need not take the system to the offline mode. You can also use schema validation optionally to enforce the control of data over each of the collections.<\/p>\n
The document data model of MongoDB maps objects in the application mode naturally. As a result, developers find it simple to master and use. The users can also represent the hierarchical associations to the store arrays seamlessly, along with other complicated structures.<\/p>\n

<\/p>\n
Flexibility of the Schema<\/h3>\n
MongoDB has a good advantage over MySQL, as the users face no constraints in terms of schema design. Some of the documents can be dropped by the developer within a collection. It is not necessary for the documents to have any relationship among each other.<\/p>\n
The supported data structures form the only drawback of this system. The schema needs to be optimized continually, based on how the data will be accessed by the application. This is because, transactions and joins are absent.<\/p>\n
Before a user can store data in MySQL, it is necessary to define every row, column and table. It is also necessary for all the rows in the table to have the same columns. This restricts the degree of flexibility, when it comes to storing data.<\/p>\n
In MongoDB, the documents are devoid any schema, that is capable of storing any data that the user desires. However, you may face issues with the consistency of data at times. MySQL is bound to make errors, as a strict schema-template is involved in the process.<\/p>\n
Query Language<\/h3>\n
The query language in both MongoDB and MySQL is strong. An unstructured query language is used in MongoDB. A document specification with the respective properties is necessary, if you want to develop a query in JSON documents and match the results.<\/p>\n
During the execution of MongoDB, a set of operators is used, and these are related to JSON. MongoDB supports boolean OR queries, although the users need to use operator ($or) in the process.<\/p>\n
MySQL, on the other hand, operates on the structured SQL language, while interacting with the database. Although it is quite simple, the language is very powerful and consists of two parts:<\/p>\n
\n- Data Manipulation Language (DML)<\/li>\n
- Data Definition Language (DDL)<\/li>\n<\/ul>\n
Relationship<\/h3>\n
The JOIN operation is not supported by MongoDB. Instead multi-dimensional types of data like arrays are supported by it. The term \u2018embedding\u2019 is used to define the position of one document inside another.<\/p>\n
The JOIN operation is one of the best aspects of MySQL. It executes the relational database and enables one to merge data from multiple tables using the SELECT command in a single query. Therefore, the users can seamlessly get the associated data using a single statement in various tables.<\/p>\n
Speed and Performance<\/h3>\n
MongoDB can control large volumes of unrestricted data, as compared to MySQL. As it enables the users to query in a way sensitive to workload, it has a much faster speed.<\/p>\n
MySQL, when compared to MongoDB, is considerably slower, when you use large volumes of data. It cannot deal with unstructured data, when the volume is greater. However, you do not have any standard benchmark, which can help you choose the right database for your requirements<\/a>. Only the data, infrastructure and your needs can evaluate what a user needs to know.<\/p>\nSecurity Model<\/h3>\n
MongoDB can establish its control over a variable set of privileges. In MongoDB, the key security features include authorization, auditing and authentication. You will also find it feasible to use Secure Sockets Layer (SSL) and Transport Layer Security (TLS) to encrypt the ends. This ensures that only the intended client can read the documents.<\/p>\n
A security model based on privilege is used in MySQL. This indicates that a user is authenticated by MySQL and can benefit on database like UPDATE, SELECT, INSERT and CREATE.<\/p>\n
