Application programming interfaces (APIs) are everywhere. Most modern web applications expose APIs that clients can use to interact with the application.
They enable software to communicate with other pieces of software — internal or external — consistently, which is a key ingredient in scalability, not to mention reusability.
Like any…
GraphQL is a query language to retrieve data from a server. It is an alternative to REST, SOAP, or gRPC in some way.
GraphQL is a new API standard and offers a revolutionary approach to building data-driven applications. …
Microservices is an architectural design for building a distributed application using containers.

This architecture allows for each service to scale or update without disrupting other services in the application.
In this article, I will explain…
Today we will cover bellow things
In current days I worked on Redis lock-in distributed system. In distributed system Locking/concurrency management is a very important thing. Without prior knowledge, many unwanted problems may occur.
More often during API design, each API may server respond after querying data from a database or from external API calling. Sometimes there are some tables those data are not frequently changed, which means those tables are not transactional.
Database query or external API calls are very much expensive. In…

Organizations and individuals didn’t get enough time to prepare for remote work or think about the best ways to smooth transition teams, processes, and culture to an online-only environment.

A database may contain one or more tables, functions, and it has a unique name. Each table is also identified by a name (e.g., “User,” “Product,” “Order”). Each table contains table relevant records with data.
SQL stands for Structured Query Language. The query language is one kind of programming language…
During an API call from a client, the server creates and assigns a thread of that request. This thread waits and is appointed until requests are served to that client.
Each server can open a limited number of threads, and if that number exceeds, then new clients request will store in…
OOP stands for Object-Oriented Programming.
OOP allows you to break down your software components into small-sized/bite-sized problems that you can solve — one object at a time.
DRY principles (Don’t Repeat Yourself) concerned about the repetition of code. You should extract typical behaviour of your code from your application and…
