Native encryption ensures secure data management with a simple deployment

The most valuable feature is the on-premises data encryption facilities. By default, we can provide encryption, and this feature in MySQL is why we prefer it over other databases. The native encryption in MySQL encourages us to use this database model more frequently compared to Oracle and other databases. With Oracle, we have to buy another solution for encryption and masking, but MySQL supports native encryption, which enhances our return on investment. It perfectly supports our ROI, and we have no issues with its functionality.

Offers simplicity and is cheaply priced

I haven't gone through the scalability aspect since I was using MySQL Server. I haven't worked to a high level in PostgreSQL, but with MySQL Server, I have managed clustering and partitioning. I think I haven't put much focus on PostgreSQL, so I am not sure how it behaves or how it works.

Pretty easy to execute my SQL queries but issues while uploading and importing my dataset

It was a bit easy to use compared to other tools. It's simple. I found it pretty easy to execute my SQL queries. Since I was a beginner, it was comfortable for me to learn SQL using SQLite. However, when I used it for my professional work and for my assignments, I found some complications. Maybe I'm not proficient with it, that's why. The main benefit for me was learning. Since I was new to SQL, SQLite helped me understand how to work with structured data.

"It is very simple to manage."

"This is an open-source solution, operates at a high speed, and supports more than one SQL language."

Cons

"MySQL could be improved by adding more automation."

"MySQL tutorials and guides could be improved. Often they are too complex for someone with no database experience to understand."

"While utilizing a comparable algorithm, is noted to be sensitive, especially when configuring the inner device."

"There are some issues with compatibility with Java environments that need to be improved. When Oracle bought this solution there were some driver changes that caused some issues with operations."

"The licensing cost of the solution is expensive, which MySQL needs to consider improving."

"The solution could have better integration and security features."

"The product is a little bit complex and it is difficult to find sufficient documentation."

"It could be more secure."

More MySQL cons

"PostgreSQL’s performance could be improved."

"When you get a large number of records in a database and start doing various queries, it can adversely impact the performance of the live running systems. That's an area we continue to look at and mean to improve, but it is not only because of PostgreSQL. It is also because of the way the schemas are put together, and certain events are triggered. So, it is because of both parties."

"PostgreSQL doesn't have a feature for temporal SQL, which is useful for gathering versions of data. This feature should be included in PostgreSQL. This feature is available in MariaDB, SQL Server, Oracle Database, and DB2."

"The database and applications can become very slow."

"We have to set up event API, which takes a lot of events from the user."

"The pricing could be better."

"It could be more secure."

"The scalability is limited."

Pricing and Cost Advice

"Enterprise editions and support are definitely needed for the heavy users who need direct support. "

"I use a free version at present."

"We are using the licensed version of MySQL."

"I don't pay for a license."

"The price of the solution is good because we have a good partner."

"MySQL Enterprise Support is not cheap, though might still be cheaper than Oracle or SQL Server. They may not have local support depending on where you’re based, but there are many smaller agencies out there that will readily provide support. You’ll need to spend some time looking around."

"I rate the solution's pricing as four out of ten, where one is cheap, and ten is expensive. For our basic needs, it's quite affordable. However, the cost increases when we need to scale up or require high availability. Our developer team of about 600 people uses MySQL without much issue. The pricing becomes more of a concern on the business side, as we have more end users and need constant database availability and scaling. In those cases, the solution gets a bit more expensive, even though it provides good value for the business."

"MySQL is cheaper than Microsoft SQL Server."

More MySQL pricing and cost advice

"There is an annual license."

"It is free, but if you need support, you can go for the commercial version called EnterpriseDB. They provide paid support, and they can even do hosting for you if you want standby and support."

"The solution requires a license."

"It is open source. There is no licensing."

"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."

"It is an open-source platform."

"The need for our customers to pay for licences is contingent on their projects and budgets."

"This solution can offer a cheaper choice for customers since it is open-source."

SQLite is an open-source, serverless, reliable, and flexible, SQL database engine. It is particularly favored in the realm of embedded database solutions and small to medium-sized projects. Unlike traditional database systems that operate on a client-server model, SQLite is a serverless database engine, meaning it runs directly within the application it powers. This unique architecture makes SQLite an ideal choice for applications where simplicity, efficiency, and minimal configuration are paramount.

SQLite is an embedded database engine, which means it operates directly within the application that uses it, without requiring a separate server process. It is designed to be cross-platform, supporting multiple operating systems, and is is compatible with a wide range of programming languages, such as C, C++, Python, Java, and more. This makes it highly portable and suitable for a wide range of applications, from mobile devices to desktop software and web applications.

The key advantages of SQLite is its reliability, the lightweight nature and efficient performance. It has a small footprint, typically requiring only a few megabytes of disk space, and can operate entirely in memory if needed. It is designed to be reliable and robust, with built-in features such as atomic commit and rollback, which ensure data integrity even in the event of system crashes or power failures. Finally, the SQLite solution requires no configuration or setup, making it easy to use and deploy. It can be embedded directly into applications without the need for complex installation or configuration procedures.

SQLite Functionality

SQL Compliance: SQLite supports a substantial portion of the SQL standard, including features like transactions, triggers, views, and indexes.
File-based Storage: SQLite stores its entire database as a single cross-platform file on the host machine's file system.
ACID Compliance: SQLite fully supports ACID (Atomicity, Consistency, Isolation, Durability) transactions, ensuring data consistency and integrity in concurrent access scenarios.

SQLite is an open-source project distributed under a public domain license, which means it can be used, modified, and distributed freely, without any licensing costs or restrictions.

To summarize, SQLite is widely used in various applications, including web browsers (e.g., Mozilla Firefox, Google Chrome), mobile applications (e.g., Android, iOS), embedded systems, and desktop software. Its simplicity, portability, and efficiency make it a popular choice for developers who require a lightweight and reliable database solution, especially in resource-constrained environments or applications with modest data storage needs.
