One of the highlights is that the cloud-native database program merged the tables’ function to speed up the website’s performance significantly. This has been a boon for the BCC as it wants to deliver an optimal experience to their website visitors. That allows fields to be created on-the-go, which enables greater flexibility to the developers.

Developers can use auto-elections to set a secondary database that will automatically overtake on the failure of the primary database. Whereas, sharding allows horizontal scaling which is considered difficult to implement with MySQL. Like other relational DBMSs, MySQL uses SQL to get the database’s access along with keeping data stored in tables. In MySQL, the user can pre-define the database scheme based on the requirements to establish rules that can govern the relationship among all the relevant fields in the tables.

Rows and columns are an SQL-specific way of data representation. MongoDB uses arrays and subdocuments – structures that are clear for applications. The main advantage of MongoDB over SQL databases, including MySQL, is the lack of predefined structure.

This pattern is actually needed for almost all of the queries we looked at here, which makes all the queries verbose and potentially daunting to debug. When aggregating one metric per device, per hour, for some 24 hour window, TimescaleDB showed 1507% the performance of MongoDB. When aggregating 10 metrics, Timescale showed 1327% the performance of MongoDB. The largest performance difference came when aggregating 5 metrics per device, per hour, for some 24 hour window, where TimescaleDB achieved 2149% the performance of MongoDB, or 21x.

The Similarities Between Postgresql And Mongodb

With this approach, data structures become like code — both are under developers’ control. MySQL is usually used to store product catalogs, purchase histories, transaction data prices, discounts, etc. For analytics and synchronized data, developers sometimes integrate non-relational databases, like MongoDB. Apart from this, its query language, Cassandra Query Language , closely resembles the traditional SQL syntax, and thus, can be easier for SQL users to understand. This gives it some leverage in any comparison of Cassandra vs. HBase. You might get the impression that this is another way of saying the same thing.

Even if your development team isn’t proficient in MySQL itself but has experience working with another SQL database, chances are they’ll get up to speed quickly. MongoDB is an open-source document-oriented database, also referred to as a noSQL database. As such, its direct competitors are CouchDB, Cassandra, and HyperTable. You need ease of use, good documentation, and robust community support. The learning curve should be less, and you need robust documentation and community support. This database went through several iterations of development.

What Makes Mongodb Popular?

There are of course cases where one of the noSQL DB’s makes perfect sense but my advice would be to think hard. I’m actually much more familiar with working with NoSQL databases than SQL databases because of the job I happened to get as my first job out of school. Immediately, I was working in an environment with TBs of data coming in every day where the use cases were quick aggregation results over this data no matter how big it grew. There are applications where it does not really matter but there is a lot of applications where hell breaks loose if they get inconsistent.

The sluggishness of the Mongo-recommended method’s ingest rate is likely due to the extra cost involved in occasionally creating new, larger documents (e.g., when a new hour or device is encountered). Not Oracle, with its decades of dominance in relational databases . Not IBM, with a waning database business but hordes of talented engineers. Not Microsoft, which had breathed new life into the RDBMS world with SQL Server. Not even open source upstarts MySQL and the increasingly popular PostgreSQL. A great advantage of SQL is to JOIN various datasets on a key field and SELECT data from each.

Because it is a NOSQL database, it is inherently secure because no SQL injection can be performed. As mentioned previously, MongoDB does not support the ACID model, instead follows the BASE [Basic Availability, Soft-state, Eventual consistent] model. Unfortunately, Stored Procedures are not cacheable on the MySQL database.

Sql Vs Nosql: Differences, Databases, And Decisions

For double rollups aggregating metrics by time and another dimension (e.g., GROUPBY time, deviceId), TimescaleDB shows large gains. And, if there were a clear winner between the two methods for simple queries, we could save ourselves some time by not implementing our full query set against both methods. This method makes it possible to do some efficient filtering when it comes to queries, but comes with a more cumbersome implementation and decreased write performance. “But for everything else, the relational model doesn’t work,” Horowitz declared.

  • For doing this we can either write a custom batch ETL process or use tools like Panoply or Xplenty.
  • Due to which it offers data localization with the assistance of replica sets and automatic sharding which also maintains an ‘always-on’ availability.
  • MySQL Cluster – built-in Automatic sharding functionality and MySQL Fabric – official sharding framework, they are rarely deployed.
  • Educative’s text-based courses are easy to skim and feature live coding environments, making learning quick and efficient.
  • While MySQL does not support auto sharding and clustering on its own, users can achieve some of the functionalities through the MySQL Cluster technology.

It also requires its values to be represented by specific data types. The JSON document structure doesn’t limit developers to breaking down the product data into multiple tables. It’s comfortable to store the essential product data together with its metadata. As the platform grows, developers can simply add new documents to accommodate more categories or analytics – there’s no need to impact the entire database.

This ensures that your application keeps serving, even if a node in the cluster goes down. If, on the other hand, your biggest concern is having information you can trust no matter what, a relational database is your best option. Both SQL and noSQL databases are tools designed to store information.

Once again, we may be biased, but we found SQL – with 5 lines of code – much simpler than MongoDB’s document format – with 72 lines of code. This is a crucial criteria for sustainable software development, since it is humans who create, maintain and use these systems at the end of the day. This https://globalcloudteam.com/ is another point in favor of SQL in the on-going NoSQL vs. SQL debate. This is another type of query common in DevOps and IT monitoring workloads. So, we first compared the two MongoDB methods using three “single rollup” queries , one “double rollup” query , and one “aggregate” query .

Although it has improved in the newer versions, MapReduce implementations still remain a slow process, and MongoDB also suffers from memory hog issues as the databases start scaling. MongoDB also provides several enterprise features, like high availability and horizontal scalability. High availability is achieved through replica sets which boast features like data redundancy and automatic failover.

Create A Database

SQL databases, also known as relational databases, were designed to store data that has a structured schema. The schema represents the design of the database to which the data should adhere to. In a structured schema, data is saved in a row-column format known as a Table and can be retrieved using queries formatted in the Structured Query Language . Database performance can vary widely depending on a number of factors – database design, application query patterns and load on the database being just a few. Since MongoDB’s document model stores related data together, it is often faster to retrieve a single document from MongoDB than to JOIN data across multiple tables in MySQL. MySQL, like many relational databases, uses structured query language for access.

Savings made using more efficient data structures can overwhelm differences in scalability; most important is to understand the use case and plan accordingly. Create new MongoDB databases and add data collections by using the commands presented in this article. Asynchronous master-slave replication, where the process goes from one master to any number of slaves, and vice versa. The master does not wait for the slaves to confirm the reception of the event. The changes to the database are queued up and written at a later time. A replica set is a set of mongod instances managing the same data set.

Compatibility varies more widely for NoSQL, and dependencies need to be investigated more carefully. Deal with secure money transactions – MySQL transactions are treated as single units, and they do not clear until each individual operational stage is successfully completed. This feature of MySQL ensures data integrity necessary for financial transactions.

You can add columns to an existing table without needing to reload the data. It can create three-dimensional tables (e.g. a row can have 0 to N values in the ‘address’ column) so it can easily ingest and query Json documents. Finally, because the entire database can have a lot of duplicated data, the actual database is quite large. There are a number of types of NoSQL databases, with the document-based solution being the most prevalent. However, you can also use key-value databases like Redis as well as tabular ones like Hbase and Acculuo.

The dynamic schemata of NoSQL databases allow representation of alternative structures, often alongside each other, encouraging greater flexibility. There is less emphasis on planning, greater freedom when adding new attributes or fields, and the possibility of varied syntax across databases. As a group, however, NoSQL languages lack the standard interface which SQL provides, so more complex queries can be difficult to execute. From analysts and engineers to IT decision makers, many are familiar with Relational Database Management Systems and the Structured Query Language used to interact with them. While these terms refer to a decades-old paradigm which remains a wide standard, today the sheer variety and depth of database systems can be dizzying. What’s more, rising volumes of unstructured data, availability of storage and processing power, and evolving analytic requirements have generated interest in fundamentally different technologies.

Being the primary MongoDB daemon process, mongod manages data requests, controls data access, and conducts background operations. A replica set consists of a number of data nodes, where one is the primary node that handles all write operations, while the others are secondary. Due to the rigidity of MySQL’s architecture, database creation and management require a lot of planning ahead to maintain high performance when the database starts growing. MongoDB supports multi-document transactions on replica sets and sharded clusters. MongoDB’s development started in 2007, and in 2009 it became open-source.

Database Deployment

Sharding, replication, versioning are all significant issues when doing performance metrics on servers. MongoDB backup functionality is provided as configurable settings in admin. The way MongoDB and SQL Databases manage data is the most significant distinction between them. In SQL databases, data is stored in form of traditional 2 dimensional row-column structure while in MongoDB rich data document model is followed, which allows storage of any type of data. MongoDB takes pride in ensuring better controlled large volumes of available data. It stores the entity data on one document and allows the users to read and write data in one place instead of multiple places.

Supports Cloud

With MongoDB, you get a flexible data model that allows you to adjust the database schema as per your business needs. MySQL, which is one of the most popular databases, supports atomic transactions. It means that you can perform multiple operations inside a transaction. MySQL is a tried-and-proven system with a rich ecosystem and high-security standards. Increased reliability, however, comes at the expense of long preparation and up-front decisions.

With a great user experience for developers and also representing data with natural clusters variably over time, MongoDB has surely gained it’s popularity for the right reasons. SQL stands for Structured query MongoDB vs PostgreSQL language, a standard language for accessing and manipulating databases. SQL can execute queries in order to retrieve/manipulate relevant data. Databases that operate or use SQL are known as SQL databases.


On the other hand, NoSQL databases are horizontally scalable. You can perform load balancing by adding more servers to your cluster to handle a large amount of traffic. You can load balance the data servers by optimizing hardware such as increasing CPU, RAM, SSD, etc.

Since it’s a distributed database, it has high availability, horizontal scaling, and geographic distribution. MongoDB is known for better controlling large volumes of unrestricted data as compared to that of MySQL. Moreover, it allows the users to query in a sensitive way to workload.
