What do we study in system design?

 System design is an essential component of software engineering. It includes the process of establishing a system's architecture, components, modules, interfaces, and data to meet given criteria. It is important to ensure that a software solution satisfies the functionality, scalability, and performance requirements.


In this blog, we will delve into the curriculum of system design and the best system design courses that can help you with it. Furthermore, we will also learn about the file system vs DBMS.


Fundamentals of System Design


  • Definition and Scope: System design has a broad reach and plays an important role in designing solid and efficient systems. Understanding its definition is critical for experts working on sturdy solutions.


  • Evolution: Tracing the growth of system design since the pre-World War II era gives information on its transformational path, particularly in tackling communication problems.


Methods of System Design


  • Logical Design: It is an abstract representation of data flow aspects such as input, output, source, destination, data storage, and overall data flow.


  • Physical Design: This strategy emphasizes data manipulation, verification, processing, and presentation features by focusing on real input and output processes.


  • Architectural Design: Understanding architectural design is essential since it focuses on satisfying requirements and establishing the structure and behavior of systems.


  • Detailed Design: Studying the preparation of raw prints involves factors such as project planning, control, user interaction, and the definition of specific sub-systems.


Why Choose System Design?


  • Scalability: System design is critical in establishing highly scalable platforms capable of managing large amounts of daily activity, as shown in popular apps like Instagram and Twitter.


  • System Design Life Cycle (SDLC): Unpacking the SDLC modules, such as data gathering, issue formulation, model generation, implementation, and improvement, offers a full picture of the system development process.


Roadmap to Learn System Design


  • Unit I: The Foundation: Covering the fundamentals of scalable and maintainable applications, data structures, query languages, storage and retrieval, and encoding and evolution.


  • Unit II:  Distributed Data: Moving on to more detailed areas of system architecture, such as replication, partitioning, transactions, the complexity, consistency, and consensus of distributed systems.


  • Unit III: Derived Data: Finishing the plan with an emphasis on derived data via batch and stream processing.

What are the 5 types of inheritance?

Image
  The concept of inheritance is considered among the most crucial concepts of object-oriented programming. Inheritance in Java is considered as a process where one class inherits the property of its parent class. When we simply define inheritance, we call it the capability of a class that derives the properties or features of other classes. The new class will be created as the ‘ derived class’ and the existing class will be known as base or parent class. Talking about the types of inheritance, it is generally of five types. Here, in this blog we are going to discuss all these inheritance types in detail with the help of examples. Without any ado, let’s get started! Types of inheritance In case of inheritance, one class derives the properties from its parent class. Here, any new class will be derived from its existing class. This new class is the derived class and our current class will be termed as the base class. When we talk about inheritance in Java, there are mainly five types ...

Remove duplicates from a sorted linked list

Image
Introduction Before reading this article, It is recommended to have an understanding of the linked list and its implementation and some basic operations on the linked list. Problem Description Create a function that takes a non-descending list and removes any duplicate nodes. Only one traversal of the list is necessary. Eg. Consider the given linked list: 1->1->1->2->2->3, the function is expected to convert the linked list into 1->2->3. In this article, we will extensively discuss the Label Control in C# & how to  remove duplicates from sorted doubly linked list .  Important:  We are supposed to delete only the duplicates i.e. only one copy of nodes should be there. Intuition:  The biggest hint given is that the list is sorted or non-decreasing in nature. From this, we can deduce that if duplicates are present, then it has to be the next one in the chain. The ideal way to approach this problem is to simply loop through the first value i...

The stock market is notoriously unpredictable. It can be hard enough to guess whether or not a particular investment will pay off or not. We know that understanding all the nuances of rules and regulations involved when buying and selling stocks is difficult. One big question many people have is, “How often can you buy and sell the same stock with transaction fee ?”  Before you start trading, you are unaware of the steps to follow to start trading and what would be the best time to buy and sell stock with transaction fee.  No matter if this is your first time investing or if you’ve been around the block a few times before, we hope that our guide will help you understand briefly on how to sell and buy stocks with in same time. Let's start with understanding stock trading and the types of traders in detail. What is Stock trading? The term "stock trading" describes the purchasing and selling of equities on a stock market. Investors that purchase and sell stocks with the inte...
