MERN stack

The MERN stack is a collection of technologies that developers use to build web applications using JavaScript.

The acronym MERN stands for MongoDB, Express, React, and Node.js. The MERN stack is a full-stack solution that uses JavaScript and JSON to create a three-tier architecture. It's popular because it only requires one programming language, JavaScript.


Each component plays a specific role in the architecture of a MERN application.

MongoDB:

MongoDB is a NoSQL database that is used to store data in a document-oriented format. This makes it ideal for storing JSON data, which is the native format of JavaScript objects.

Express:

Express is a web framework that is used to build the backend of a MERN application. It provides a number of features that make it easy to develop and deploy web applications, such as routing, middleware, and templating.

React:

React is a JavaScript library that is used to build the frontend of a MERN application. It provides a number of features that make it easy to build user interfaces, such as components, state management, and virtual DOM.

Node.js:

Node.js is a JavaScript runtime environment that is used to run the MERN application. It provides a number of features that make it ideal for developing web applications, such as event-driven programming, non-blocking I/O, and a large number of modules.


The MERN stack follows a three-tier architecture, which is a common pattern for designing web applications. The three tiers are:

Presentation tier:

The presentation tier is responsible for displaying the user interface of the application. It is typically implemented using a JavaScript library such as React.

Application tier:

The application tier is responsible for handling the business logic of the application. It is typically implemented using a web framework such as Express.

Data tier:

The data tier is responsible for storing and retrieving data. It is typically implemented using a database such as MongoDB.


Here are some of the benefits of using the MERN stack:

  • use JavaScript for both the frontend and backend of the applications
  • scalable
  • build a wide variety of web applications

Scaled Agile Framework (SAFe)

The Scaled Agile Framework (SAFe) is a set of organizational and workflow patterns for implementing agile practices at an enterprise scale. The framework is a body of knowledge that includes structured guidance on roles and responsibilities, how to plan and manage the work, and values to uphold. Scrum is a simple, flexible approach to adopting Agile that's great for small teams. SAFe is an enterprise-wide Agile framework designed to help bring Agile beyond the team and into the company as a whole. Scaled Agile has built a comprehensive level that includes all the four layers called the team, program, large solutions, and portfolio level. 4 Layers: Portfolio - Strategy, Vision, Roadmap, Strategy goal, Decision making, Budget, Portfolio level metrics,  Program - Align multiple teams towards a common mission, Bring together all the Agile teams, transparency, collaboration, and synchronisation, Scrum of Scrums, Product Owners to define the overall vision.

Lessons learned in Project Management

Lessons learned in Project Management Lessons learned (it may be +ve or -ve) in project management are the knowledge gained during a project that can be used to improve future performance. Lessons learned are documented with solutions to provide future project teams with information that can increase effectiveness and efficiency. Every project manager should be well aware of the impact lessons learned can have on the current and future projects. However, despite knowing the value of lessons learned, not everyone makes full use of them.  The lessons learnt documented using below process flow: 1) Identify: Identify comments and recommendations for use in future project. This is usually done through a project survey that is sent out to all team members. Various questions connected to a project help the participants share their lessons learned.  2) Document: Document and share the findings 3) Analyze: Analyze the finding and find the solution 4) Store: Store in a repository 5) Ret...
