Top Databases Every New Developer Should Know in 2021

According to beginners, these are the top databases best and easiest to use.

Most new developers are unsure which database is best for their project because they don’t want to make a mistake. First and foremost, let’s establish a database. A database is a type of storage facility that stores and organizes data in an electronic format so that it may be used and retrieved later.

Some databases are better than others because they are easier to use, have more features, or are safer. Beginners rank some databases more than others based on these characteristics. So there you have it: the rankings and the reasoning behind them.

1. Top Databases: Firebase

Firebase is a Google program that gives developers access to a number of tools for building online and mobile apps. Firebase is simple to use and set up because it is available over the web. Firebase provides hosting and storage in addition to being a database. A real-time database and a firestorm database are also included. Firebase is perfect for newbies because it is an all-in-one bundle for developers.

Here are a few reasons why Firebase is better than its competitors:

Easy to Use
Of all the databases listed, Firebase is the most user-friendly and straightforward to use. It combines the advantages of MongoDB and MySQL. Firebase has a lot of documentation, it’s web-based, so it’s easy to set up, and it has other services like hosting and storage that could be useful in the future. Firebase has the most comprehensive database documentation; it explains each step and what it accomplishes. Making it simple to utilize for inexperienced developers. The documentation can be found here.

Fast and Safe
Because it is a cloud service, Firebase is one of the fastest-running apps. It is faster than many servers. This signifies that its database is among the world’s quickest, with queries that are faster than most NoSQL databases. Firebase is a very secure platform. One of the reasons for this is because it is owned by Google, one of the top technology corporations in the world. The server-side security of the application is determined, which means that the person in charge can create all of the rules, grant read and write access, and do a variety of other things to make the owner’s program as secure as possible.

Firebase has only one disadvantage

• Hard to use for large/complex projects: Large structured data is difficult to discover in Firebase, which is inconvenient because practically every other database permits it.

2. Top Databases: MongoDB

Due to its user-friendly documentation, scalability, and a multitude of other characteristics that other databases do not give, MongoDB is one of the most popular NoSQL databases in the world. Many companies, like Uber, Lyft, and AWS technologies, use MongoDB, which is similar to MySQL. MongoDB is easy to use and can be mentioned on a CV to impress potential employers. Some of the reasons why MongoDB is considered one of the best NoSQL databases are as follows:

Detailed Documentation
The value of documentation is frequently overlooked, especially by beginners. Good documentation makes the life of developers so much easier. This is due to the fact that they are not required to seek help or answers. When they are able to rely only on the database’s documentation. This is the documentation link.

Easy to Set Up
MongoDB is one of the most user-friendly databases on the market. It’s designed for beginners to use in their projects. The paperwork outlines everything that has to be done. It takes roughly 1-2 hours to download, set up, and comprehend MongoDB. It takes less time and effort to set up than MySQL.

Some of the disadvantages of using MongoDB

• Indexing: If there are inconsistencies in the code or the indexing isn’t implemented correctly, MongoDB will run slowly.
• Transactions: MongoDB uses multi-document ACID (Atomicity, Consistency, Isolation, and Durability) transactions. This is a drawback because it can result in data corruption.
• Joins: In MongoDB, document joining can be a time-consuming process. It does not support joins because it is a relational database.

3. Top Databases: MySQL

MySQL is open-source, simple to use, and well-known among significant organizations in the programming industry. MySQL is utilized by a number of prominent companies, including Twitter, Airbnb, Netflix, and Amazon. As a result, learning MySQL not only makes projects easier to complete but also adds to one’s resume. Here are some additional in-depth explanations:

Reliable
Anyone who uses the internet knows how important it is to keep personal information safe. MySQL, on the other hand, maintains data security and offers a number of encryption options. Unauthorized people cannot read the data because of these data encryption measures. When efforts to attack the database are detected, MySQL shuts them off instantly. Data backup is also beneficial because it allows for data recovery at any time.

Secure
Money is highly valued by individuals, and most people regard money transfer to be a stressful event. MySQL is fortunately utilized for financial transactions; it is a single unit, which means that if one stage of the transaction fails, the entire process fails. This is advantageous since the money will not be sent until the full procedure is completed if the step fails.

Some of the disadvantages of using MySQL

• Cannot be scaled: Because of the query syntax’s flexibility, MySQL cannot be scaled.
• Slow with older versions: The older MySQL versions contain flaws and are extremely slow; yet, even the current ones can be slow at times.
• Few stability issues: MySQL is unreliable, and it has a tendency to fail after a few weeks of flawless operation.

To summarize, all of the databases described are fantastic, and the choice ultimately comes down to personal preference; nonetheless, the majority of beginners who use these databases agree that Firebase is the best. Firebase is intended for programmers who are just getting started; once that period is complete, databases such as MongoDB and MySQL become a better option.
