High-volume transactions have reduced failures and improve customer service efficiency

The best feature is performance, because of which I decided on PostgreSQL. I have also enabled the PG vector plugin on top of PostgreSQL. I have the opportunity to use two different features and two different flavors in a single product, which is the best thing about PostgreSQL. Initially, we had some hiccups around the performance part, but later we did indexing in PostgreSQL and now it is working very well. Even when we are doing 100,000 transactions in a day, PostgreSQL is working excellently. The interface is another best feature. If I need to do any query, I simply install the plugin on my local, which is pgAdmin. Through pgAdmin, I am able to communicate with PostgreSQL and execute all my SQL queries. I am getting a better UI with PostgreSQL as the backend, which is also one of the best options. PG vector is also very strong from PostgreSQL where I have implemented RAG and on a daily basis, I inject thousands of pages of PDF. More than 100 PDFs are coming into my system and one PDF is around 1,000 pages. We are injecting them into PostgreSQL and converting them into dimensions and inserting them into PG vector. The level of transactions we are doing on a daily basis is substantial, and we are getting very good throughput and low latency from PostgreSQL. When we were doing more than 50,000 transactions in a minute with the previous database, we were getting a lot of latency issues with threads getting blocked and abruptly closed unwantedly. After doing extensive research, we decided to move to PostgreSQL. Now, we are doing around 100,000 transactions in PostgreSQL and we are getting good throughput with no latency.

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.

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.
