Business Logic is the decision logic that supports the requirements of business processes.

A domain model is an abstract representation of the key concepts and their relationships within a specific business domain.

An approach to software development that focuses on modeling complex domains.

Architectural style that splits applications into autonomous, small services to enable scalability, independence, and faster deployment.

An architectural style that consolidates all application functions into a single cohesive codebase.

An architectural paradigm where applications run on managed cloud services and event-driven functions without managing server infrastructure.

An architectural approach that uses services as the central building blocks for software application development.

The CAP theorem describes the fundamental limitations of distributed databases regarding consistency, availability, and partition tolerance.

Strategy for temporarily storing frequently accessed data to reduce latency and load. Includes forms such as in-memory, HTTP, and CDN caches plus rules for consistency, invalidation, and capacity management.

Mechanisms and patterns for copying and synchronizing data across storage systems to improve availability, scalability, and fault tolerance.

Data structures that accelerate queries by providing fast lookup paths into tables, optimizing read access.

Eventual Consistency is a consistency model that ensures that all copies of a database will eventually converge, without requiring immediate consistency at all times.

HTTP caching describes mechanisms and rules for storing HTTP responses to reduce latency, bandwidth usage, and backend load.

Non-relational database systems with flexible schemas, designed for horizontal scalability and varied consistency models.

Horizontal partitioning of data across multiple nodes to enable scaling and load distribution.

A fundamental concept for conducting transactions across various systems.

A NoSQL database that allows for schema-less data storage.

MySQL is a widely used open-source database known for its reliability and high performance.

Oracle is a comprehensive database solution designed for enterprises.

PostgreSQL is a powerful, open-source object-relational database management system.

Redis is an in-memory data structure store that functions as a database, cache, and message broker.

SQLite is an embedded, serverless SQL database engine implemented as a single library, suitable for local persistence in applications.

Asynchronous communication enables information exchange without time constraints.
