Many NoSQL databases are now able to serve as transactional databases. A brief history of NoSQL & ACID compliance and what DBS support it.

Can NoSQL Database be Transactional?
NoSQL databases started gaining traction and interest around 2006, making them 15 years old. When they started, they could not serve as a transactional database. That meant looking to relational databases anytime you needed transactional DB resources.

But like all technology, NoSQL is ever-evolving and building out new use cases. Some NoSQL databases can now serve as transactional databases but be careful when selecting one as not all include these features.

Get insights into Buy Mobile Database what a transactional database is, changes to NoSQL databases to allow for transactions, and the options available to you when building out transactional applications.

What Is a Transactional Database?
The average technology user probably thinks little about how they are able to perform simple tasks.

Take the example of a social media platform. The user knows only what they see, which is a simple interface displaying posts from friends, family and their favorite brands.

What is happening in the background requires highly sophisticated databases. Without a database, all those social media posts, the profile images for each user and the timestamps for when they took place can’t exist.

Transactional databases are database management systems (DBMS). A transaction is any data manipulation instruction or inquiry to access or write data. With transactions, you can extract or modify large data volumes with incredible ease.

In its simplest form, a data transaction is the saving, altering or controlling of data within a system. These transactions cannot harm the data’s integrity, which means that while writing the data in real-time, you also need to be able to present accurate data in real-time.

The data that a transactional database manages could be preferences, purchase data or even information like a social media post.

Transactional DBs generally have these three key features.

Data accuracy: transactional DBs are generally ACID compliant (this stands for atomicity, consistency, isolation and durability). That means that they can preserve large volumes of data accuracy in real-time. Historically, ACID compliance is one place where NoSQL databases have struggled. But new developments are helping overcome this to the point where some NoSQL databases can be ACID compliant.
Data durability: Best Database Provider Transactional databases ensure the durability of the data and in case of any failure/crash the db is able to recover the data and brings the database back to the normal state. This is very critical when it comes to dealing with financial, accounting, (etc.) data.
Flexible: users can edit data without touching other areas of other critical data sets. You can edit data without harming the system’s architecture. Users can easily pull transactional history even when data is housed in a limited context. NoSQL databases are far more flexible than relational databases, so this is not a challenge for this technology.
Speed: complete transactions in milliseconds with a transactional Buy Mobile Database . Speed should not be an issue when using one of these databases as you should be able to create queries and write data at incredible speeds. Speed is one of the greatest strengths of NoSQL databases, so it’s no surprise that these databases can meet this need.
Ultimately, overcoming the ACID compliance need is the greatest hurdle for making NoSQL databases serve as transactional databases.

Up until recently, the best transactional databases were relational databases, including SQLite, Oracle, MySQL and Microsoft Access. But now let’s look into how NoSQL is changing to meet these needs for real-time data integrity and accuracy.

Changes to NoSQL Databases to Allow for Transactions
NoSQL databases have never been databases without SQL. NoSQL actually stands for “not only SQL.” That makes these databases excellent for housing structured, unstructured and semi-structured data all in one place while taking advantage of the scalability of NoSQL databases.

But the first 10 years or so of NoSQL databases was dedicated to getting data architects and IT teams on board with the idea of a new way of data modeling. The industry had to understand the value of these highly scalable databases. And IT teams had to understand that users could query some data without transactional guarantees while any lost data could be re-computed back from raw data later.

As adoption of NoSQL databases increased and the industry saw how Best Database Provider non-relational databases could aid in creating internet-scale user-facing applications despite durability and scaling challenges, NoSQL began to develop new functionality.
