![]() ![]() In case of a server failure, you can always retrieve your data from the copies stored in other servers. This feature is helpful for data backups and disaster management. Replication: MongoDB allows you to make several copies of your data using replication ( replica sets) and deploy them on various servers.Now, let’s move on to looking at some of the main features of MongoDB: MongoDB or MySQL? □ Which database management system is right for you? □ Click to Tweet Features of MongoDB As a result, it facilitates higher speed and storage requirements. MongoDB offers greater security, reliability, and efficiency in addition to the flexibility of modifying the data structure or schema. The key/value pairs can be structured differently from one document to another. These documents contain a series of value or key pairs of different types, such as nested documents and arrays. Instead of storing data in rows and columns, MongoDB takes a document-oriented design that represents data in various JSON-like documents and collections. We do not need to define schema first.MongoDB differs from traditional database systems in terms of how that data gets stored. Data of any structure can be accessed and stored easily and quicklyģ. Support is available in the free version, but you will need to pay for it.ģ. You might have to spend a lot of time and effort to get MySQL to do the things that other systems can do automatically, e.g. It can be used to work with other databases, including DB2 and Oracle.ġ. It offers a lot of functionality even for a free database engine.ģ. Pros and Cons of MongoDB and MySQL : MySQLĢ. And if you need to handle a large volume of data then MongoDB will help you. MongoDB : if your data is unstructured and complex, or if you can not pre-define your schema, you have better option for MongoDB. MySQL : If your data is structured and simple, Or if you can define your schema, if smaller volume of data then you can use MySQL. you should take care about your project requirements. MySQL and MongoDB both have their weaknesses and strengths. MySQL: INSERT INTO users (user_id, fname, lname, phone) VALUES (‘jane’, ‘deo’, ‘7858458891’).Inserting records into the users table:. ![]() Selecting records from the users table:.MongoDB stores data in the form of “JSON-like” documents and MySQL stores data in the form of “rows” of the table. The difference between the way data is stored and represented in both the databases is quite different. This cannot be achieved by MySQL but This can be achieved in MongoDB, any new field can be inserted irrespective of the schema and is thus known to have dynamic schema. Example: In a table, if there are columns for first name, last name and there is need to enter ‘phone’ in new column in one of the entries, it will not take it as the column is not defined in schema. The inputs should be entered as per the given schema. We have to defined database schema first. We cannot change schema of the table in MySQL. Documents belonging to a particular class or group as stored in a ‘collection’ In MongoDB. Each individual records are stored as documents In MongoDB. Individual records are stored as rows in a table and A table is used to store rows of similar type in MySQL. We have to predefine our database schema based on the requirement in MySQL, while in MongoDB there is no need to define database schema first. MongoDB is document oriented an open-source database developed by MongoDB, Inc. MySQL is a open-source relational database management system that is developed and supported by Oracle Corporation. ![]()
