System design is the process of defining the architecture, components, modules, interfaces, and data structures for a system to meet specific requirements.

System Design

Persistence in system design refers to the capability of the system to store data in a manner that it survives power failures, crashes, or errors. It's a critical aspect of any system design.

Persistence

Observability refers to how well internal states of a system can be inferred from its external outputs. It's crucial for understanding system performance, identifying issues, and ensuring optimal operation.

Observability

Infrastructure refers to the fundamental physical and virtual resources supporting a system. It involves hardware, software, networks, and facilities necessary for system operation and management.

Infrastructure

Testing is a critical phase in the system design process where the system is evaluated to ensure it functions as intended, maintains performance under different conditions, and detects any flaws or errors.

Java is a general-purpose, object-oriented programming language. It is the most widely used programming language for building enterprise-scale applications.

Java

Serverless architecture allows developers to build and run applications without the need to manage servers, with infrastructure managed by the cloud provider.

Serverless Architecture

Object design is a software design approach focused on defining and interacting with objects to solve software problems, based on the principles of object-orientation.

Object Design

Clean code is a development practice focused on writing code that is easy to understand, read, and modify, with the aim of improving software quality and reducing complexity, facilitating maintainability and system evolution.

Clean Code

Monolithic architecture is a software design approach where all application functions reside in a single instance or component, simplifying development and testing.

Monolithic Architecture

Microservices architecture is a software design style that breaks an application into small autonomous services, each running its own process and communicating through APIs.

Microservices Architecture

MVC and MVVM are software design patterns for structuring code into separate logical layers, with the aim of improving maintainability, scalability, and code reuse.

MVC-MVVM

Relational databases use a structured, tabular format to store data, enabling complex queries and relationships. Examples include MySQL, PostgreSQL, and Oracle.

Relational Databases

NoSQL databases, non-relational by design, provide high scalability and flexibility. They are ideal for handling large data sets and non-structured data. Examples include MongoDB, Cassandra, and CouchDB.

NoSQL Databases

MongoDB is a leading NoSQL database that stores data in flexible, JSON-like documents. It provides horizontal scalability and allows for querying and indexing of data.

MongoDB

Transactions in system design refers to a single logical operation on data. It's a sequence of operations executed as a whole, ensuring data integrity and consistency.

Transactions

Log management entails the process of generating, transmitting, storing, analyzing, and disposing of log data from different sources. It's essential for troubleshooting, security, compliance, and understanding user behavior.

Log management

Application monitoring involves tracking the performance and functionality of software applications. It aids in the early detection of issues, ensuring smooth and efficient application performance.

Application monitoring

Caching is a technique for storing data in temporary storage areas, or 'caches', to improve data retrieval speed and system performance, reducing the workload on primary storage resources.

Caching

Message Queues allow different parts of a system to communicate and process operations asynchronously. They provide temporal decoupling and load balancing, ensuring reliable data flow.

Message queues

Container Orchestration automates the deployment, scaling, networking, and management of containerized applications. It simplifies system management and enhances resource efficiency.

Container orchestration

Unit testing focuses on validating individual components, functions, or classes in isolation to ensure that each part of the system operates correctly and handles expected inputs and outputs.

Unit testing

Test doubles are objects used in testing to replace real components with controlled versions, allowing for better isolation, control, and predictability during the testing process.

Test doubles

Clean testing refers to creating tests that are easy to understand, maintain, and modify, by following best practices like clear naming conventions, avoiding repetition, and ensuring code readability.

Clean testing

Redis is an open-source, in-memory data structure store, used as a database, cache, and message broker. It supports various data structures and provides high performance.

Redis

Java Fundamentals refers to the basic concepts and principles essential to developing applications in Java. This includes understanding data types, variables, operators, control flow statements, loops, classes, objects, methods, and more.

Java Fundamentals

Advanced Java Concepts refer to a more complex set of topics in Java programming, going beyond the basics to include aspects such as multithreading, concurrency, generics, collections, lambda expressions, streams, networking, and database connectivity (JDBC).

Advanced Concepts

Gradle and Maven refers to two prevalent build tools used in Java software development. These tools automate and manage the software build process, including compilation, testing, packaging, and deployment tasks.

Build Tools

Spring is a Java framework that provides a comprehensive programming and configuration model for modern Java-based enterprise applications. The framework includes Spring Core for dependency injection, Spring Cloud for developing cloud-native applications, and Spring Security for authentication and authorization.
