🚀 Empower your career with data engineering skills and secure your dream job in this growing field⚙️

✔️ After receiving a lot of queries, I've made some revisions to my original suggestion and I highly recommend following this exact sequence. Trust me, it will make things much easier for you.

♻️ It's easy to get lost in the vast amount of information available when it comes to learning new skills, especially in the field of data engineering.

🔗 However, with a solid roadmap and some dedication, it is possible to enter the field of data engineering in 2023.

Here are some steps you can follow to make sure you're on the right track -

🔶 Learn RDBMS, NoSQL databases, SQL, and data warehousing concepts :

As a data engineer, you'll be working with large amounts of data stored in databases. Familiarize yourself with different types of databases and how to query them using SQL. Learn one RDBMS and one NoSQL database, then familiarize yourself with data warehousing concepts.

1. Learn Data Warehousing concepts - https://lnkd.in/eKnVbFAB
2. Learn MySql - https://lnkd.in/efk-Mi3c
3. Learn and practice SQL - https://lnkd.in/efMKFkfX
4. Learn Azure Cosmos DB - https://lnkd.in/eNVyc6Mq
   
🔶 Learn Python and PySpark :

These are essential tools for data engineers.

Those who worked on banking application can use this

Q4.) What is the module in project banking application? How many number of modules used in your project? On which module you worked in your project?

A4.) The modules in a project banking application are typically related to the different functions of a bank, such as customer accounts, payments, transfers The exact number of modules used in my given project is dependent on the specific requirements of the project. I worked on the customer accounts module, which included features such as creating customer accounts, managing customer profiles, and monitoring customers’ banking activity.

The modules in project banking application include:

1. Account Management
2. Money Transfer
3. Online Banking
4. Payments and Bill Management
5. Customer Support

We used 5 modules for our project. I worked mainly on the Account Management and Online Banking modules.

worked on the Account Management Module, which is responsible for managing the bank accounts of the users. This module was responsible for customer registration, account opening, account closure, account inquiry, account maintenance, and various other account related activities.

What is the module in project user management application? How many number of modules used in your project? On which module you worked in your project?

The modules in a project user management application include user profiles, user access management, user authentication and authorization, user activity tracking, user notifications, user preferences and customization, and user data management.

The number of modules used in the project depends on the specific requirements of the project. I worked on the user authentication and authorization module in my project.

What is the module in project employee management application? How many number of modules used in your project? On which module you worked in your project?

The modules in a project employee management application are typically related to the different features of the application. These modules include HR Management, Attendance Management, Leave Management, Performance Management, Payroll Management, and others. The number of modules used in the project will depend on the application's scope and the requirements of the project. For example, a basic employee management application might only require the HR Management and Attendance Management modules, while a more robust application might require all of the modules listed above.

I worked on the Attendance Management module of the project. This module allowed users to record and track employee attendance, including calculating working hours, leaves, overtime, and more.

Everyone please don't write same topics that's why i have shared multiple projects information

Some of you write about employee management , user management , banking application

What is the difference between linked list and arraylist

A linked list is a linear data structure where each element is a separate object that holds data and a pointer to the next element in the list. Linked lists are ideal for dynamic memory allocation, as they can grow or shrink in size as needed.

An ArrayList is a dynamic array that stores objects. It is similar to an array but can grow or shrink in size as needed. It is more efficient than a linked list for storing and retrieving data, but it does not offer the same flexibility when it comes to memory allocation and insertion/deletion operations.

Instead of learning solutions of LeetCode questions, understand patterns! 🙂

𝑴𝒖𝒔𝒕 𝑺𝒂𝒗𝒆 𝒂𝒏𝒅 𝑺𝒉𝒂𝒓𝒆 !!!!

For ex.

If input array is sorted then
- Binary search
- Two pointers

If asked for all permutations/subsets then
- Backtracking

If given a tree then
- DFS
- BFS

If given a graph then
- DFS
- BFS

If given a linked list then
- Two pointers

If recursion is banned then
- Stack

If must solve in-place then
- Swap corresponding values
- Store one or more different values in the same pointer

If asked for maximum/minimum subarray/subset/options then
- Dynamic programming

If asked for top/least K items then
- Heap

If asked for common strings then
- Map
- Trie

Else
- Map/Set for O(1) time & O(n) space
- Sort input for O(nlogn) time and O(1) space
