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.
Learning Path
Unit Testing
Unit testing is a software testing approach that evaluates individual components or units of a program in isolation. Test cases are written to verify that each unit functions correctly as intended. It helps identify bugs early in the development cycle and ensures that each unit of code works independently.
Integration Testing
Integration Testing is a software testing technique where individual software modules are combined and tested as a group. It verifies if the modules can work together as intended, detecting any interactions or interface issues between the components. Integration Testing aims to ensure smooth communication and functionality between different software components.
System Testing
System Testing involves testing the entire system as a whole to ensure all components work together correctly. It validates the system's compliance with specified requirements, its functionality, reliability, performance, and security. System Testing is essential to identify defects that may arise from the integration of components.
Acceptance Testing
Acceptance Testing is the final phase of the software testing process where the system is evaluated to ensure it meets all specified requirements and functions as expected by end-users. It is conducted to validate the overall quality and readiness of the software product before its release into the market.
Regression Testing
Regression testing is the process of re-running tests on an application after changes have been made to ensure that existing functionalities have not been negatively impacted. It validates that new code modifications have not introduced any errors or bugs into previously tested features, helping maintain software quality and stability.
Debugging
Debugging is the process of finding and fixing errors or bugs in a computer program. It involves identifying issues by tracing the program's execution, analyzing code, and testing for correct behavior. Debugging is essential in software development to ensure programs work as intended and deliver a quality user experience.
Code Documentation
Code documentation is the process of describing the functionality, purpose, and usage of software code. It typically includes comments within the code itself, as well as external documentation files. Documentation helps developers understand and maintain the code, and makes it easier for others to use and collaborate on the codebase.
Code Optimization
Code optimization is the process of improving code to make it more efficient, faster, and use fewer resources. This involves refining algorithms, removing redundancy, and minimizing runtime and memory usage. The goal is to enhance program performance without altering its functionality, ultimately creating more streamlined and optimized code.
Software Design Patterns
Software design patterns are general, reusable solutions to commonly occurring problems in software design. They provide a blueprint for structuring code to improve its readability, scalability, and maintainability. By following design patterns, developers can leverage proven approaches to design software systems that are flexible and robust.
