Coding Projects

These are top 5 data structures and algorithms projects, allowing you to dive deep into the world of DSA 💪🏻 •Project 1: Snakes Game (Arrays) The Snakes Game project is a classic implementation of the popular game Snake. This project allows you to understand the concepts of arrays, loops, and conditional statements. You can further enhance the game by incorporating additional features such as score tracking and power-ups. •Project 2: Cash Flow Minimizer (Graphs/ Multisets/Heaps) The Cash Flow Minimizer project involves solving a cash flow optimization problem using graphs, multisets, and heaps. Given a set of transactions among a group of people, the objective is to minimize the total number of transactions required to settle all debts •Project 3: Sudoku Solver (Backtracking) The Sudoku Solver project aims to solve the popular Sudoku puzzle using backtracking. This project allows you to understand the backtracking algorithm, which is widely used in solving constraint satisfaction problems. •Project 4: File Zipper (Greedy Huffman Encoder) The File Zipper project focuses on implementing a file compression utility using the Greedy Huffman encoding algorithm. This project provides a practical application of the greedy algorithm and helps you understand the trade-offs between compression ratio and execution time. •Project 5: Map Navigator (Dijkstra’s Algorithm) The Map Navigator project aims to develop a navigation system using Dijkstra’s algorithm.

Things that a Web Developer must know concerning database storage and management: 🟡Characteristics of relational/non-relational data. 🟡Knowledge of NoSQL databases. 🟡Knowledge of web storage. Following are some of the best databases you must learn 🟧Relational databases: Within the tables, data is stored in rows and columns. The relational database management system (RDBMS) is the program that allows you to create, update, and administer a relational database. Microsoft SQL Server, Oracle Database, MySQL, PostgreSQL, and IBM Db2 are examples of rational databases. 🟧NoSQL: NoSQL databases (aka “not only SQL”) are non-tabular, and store data differently than relational tables. NoSQL databases come in a variety of types based on their data model. The main types are document, key-value, wide-column, and graph. Apache Cassandra, MongoDB, CouchDB, and Couchbase are examples of NoSQL. 🟧Cloud database: It refers to any database that’s designed to run in the cloud. Like other cloud-based applications, cloud databases offer flexibility and scalability, along with high availability. Cloud databases are also often low-maintenance since many are offered via a SaaS model. Microsoft Azure SQL Database, Amazon Relational Database Service, Oracle Autonomous Database are examples of cloud database.. ⚡Technology Stacks- MEAN, MERN, MeVn, Lamp 🔰MEAN Stack: MEAN stack development refers to the development process that falls within these particular sets of technologies MongoDB, ExpressJS, Angular, NodeJS. 🔰MERN Stack: It is is one of several variations of the MEAN stack (MongoDB, Express, Angular, Node), where the traditional Angular frontend framework is replaced with React JS. The main benefit of using MERN is the integration of React and its powerful library and capability to use code simultaneously on servers and browsers. 🔰MEVN Stack: Other variants of MEAN Stack, the MEVN Stack (MongoDB, Express, Vue, Node), and really any frontend JavaScript framework can work. It is the open-source JavaScript software stack that has emerged as a new and evolving way to build powerful and dynamic web applications 🔰LAMP: It is an old classic industry standard when it comes to time-tested web development stacks, which comprises MySQL (Relational Database Management), Linux (Operating System), PHP (Programming Language), and Apache (HTTP server).
