ACID Properties
ACID properties are key principles in database management ensuring reliability and consistency of transactions. ACID stands for Atomicity (transactions are all or nothing), Consistency (data remains valid), Isolation (transactions do not interfere), and Durability (committed data is persistently stored). These properties maintain data integrity and reliability.

Monolithic Architecture
Monolithic architecture is a software design approach where an application is built as a single unit. All components are interconnected and run as a single system, making it simpler to develop and deploy. However, it can be challenging to scale and maintain due to its tightly-coupled nature.
Service-Oriented Architecture (SOA)
Service-Oriented Architecture (SOA) is a software design approach where services are provided to other components by application components, through a communication protocol over a network. It promotes loose coupling between software components, allowing them to be distributed, reused, and maintained independently, enhancing flexibility and scalability of systems.
RESTful Services
RESTful services are a way of designing and implementing web services that adhere to the constraints of the REST architectural style. They use standard HTTP methods like GET, POST, PUT, and DELETE to manipulate resources. RESTful services are stateless, scalable, and loosely coupled, making them ideal for distributed systems.
API Design
API design involves creating a clear and structured interface for software systems to communicate with each other. It focuses on defining how different components interact and exchange information. Good API design entails simplicity, consistency, and flexibility to ensure seamless integration and ease of use for developers.
Model-View-Controller (MVC)
Model-View-Controller (MVC) is a software design pattern that separates an application into three interconnected components: Model (data and business logic), View (user interface), and Controller (mediates interactions). This separation promotes code reusability, scalability, and maintainability in building web and desktop applications.
Observer Pattern
The Observer Pattern is a behavioral design pattern where an object (the subject) maintains a list of its dependents (observers) and notifies them of any state changes. This enables a loosely coupled relationship between the subject and observers, allowing multiple entities to react to changes in the subject.
Factory Pattern
Factory Pattern is a creational design pattern in programming used to define an interface for creating objects. It delegates the responsibility of instantiating objects to subclasses. This pattern helps in creating objects without exposing the logic for their creation. It promotes code reusability and enhances flexibility in object creation.
Singleton Pattern
Singleton Pattern is a design pattern in object-oriented programming that ensures a class has only one instance and provides a global point of access to it. It is commonly used for resources that should be shared across the application, like database connections or configuration settings.
Database Management Systems (DBMS)
A Database Management System (DBMS) is software that organizes, stores, and manages data efficiently. It provides a structured way to access, update, and manipulate data in databases. DBMS ensures data integrity, security, and consistency by enforcing rules and allowing multiple users to interact with the data concurrently.
