2. Software Development Life Cycle (SDLC) 01

3. Software Development Life Cycle (SDLC ) . SDLC stands for Software Development Life Cycle. It is a structured process followed by software development teams to design, develop, test, and deploy highquality software products. The SDLC typically consists of several phases

4. Software Development Life Cycle (SDLC ) . 1 Planning Phase: During this phase, the project requirements are gathered and analyzed. This involves understanding the objectives of the database, the data to be stored, and the functionality required. A database development plan is created which outlines the scope, objectives, timeline, and resources required for the project.

5. Software Development Life Cycle (SDLC) . 2 Analysis Phase : In this phase, detailed requirements are documented. This involves understanding the data model, relationships between entities, and defining attributes for each entity. Data flow diagrams and entity relationship diagrams (ERDs) are often used to visualize the data structure and relationships. 3 Design Phase: Based on the requirements gathered in the analysis phase, the database schema is designed. This includes defining tables, columns, data types, constraints, and relationships. Normalization techniques are applied to ensure data integrity and minimize redundancy. Diagrams such as EntityRelationship Diagrams (ERDs), schema diagrams, and data flow diagrams may be created to represent the database design.

6. Software Development Life Cycle (SDLC) . 4 Development Phase : In this phase, the database is built according to the design specifications. This involves creating tables, views, stored procedures, and other database objects. SQL scripts or database management tools are used to execute the DDL (Data Definition Language) statements to create the database structure. 5 Testing Phase : Once the database is implemented, it undergoes various tests to ensure it meets the functional and performance requirements. Testing includes unit testing, integration testing, and system testing to identify and fix any defects or issues.

7. Software Development Life Cycle (SDLC) . 6 Deployment Phase : After successful testing, the database is deployed to the production environment. This involves transferring data from the development or testing environment to the production environment. Deployment may also involve setting up security permissions, configuring backups, and establishing monitoring processes. 7 Maintenance Phase : Once the database is in production, ongoing maintenance and support are required. This includes monitoring performance, applying updates and patches, and making modifications as needed to meet changing requirements

8. Scenario: You're leading a software development team tasked with creating a new mobile app for a client. The client wants the app to allow users to track their daily fitness activities, such as running, cycling, and swimming. They also want features for setting fitness goals, monitoring progress, and sharing achievements on social media. The client emphasizes the importance of user-friendly design and seamless performance across different mobile platforms.

9. Question: Outline the steps you would take in each phase of the SDLC to ensure the successful development and deployment of the fitness tracking mobile app for the client.

10. Solution: Planning: Meet with the client to gather detailed requirements for the app, including desired features, target audience, platforms (iOS, Android), and any specific design preferences. Define project scope, objectives, and deliverables, and create a project plan outlining timelines and resources needed. Conduct market research to identify competitor apps and analyze user preferences and trends in fitness tracking apps. Analysis: Work closely with the client to prioritize and refine requirements, ensuring they align with the client's goals and user needs. Create user personas and user stories to capture different user scenarios and workflows. Conduct usability studies or surveys to gather feedback from potential users on their expectations and preferences for the app's features and design.

11. Solution: Design: Develop wireframes and mockups to visualize the app's user interface (UI) and user experience (UX), incorporating feedback from the client and users. Define the app's architecture, including data models, system components, and integration points with external services (e.g., GPS for tracking activities). Create design prototypes to demonstrate key interactions and navigation flows within the app. Implementation: Begin coding the app using appropriate programming languages and frameworks (e.g., Swift for iOS, Kotlin for Android). Follow best practices for mobile app development, including modular design, code reusability, and adherence to platform specific guidelines. Implement features incrementally, conducting regular code reviews and testing to ensure code quality and functionality.

12. Solution: 5. Testing: Develop test cases and scenarios covering both functional and nonfunctional requirements of the app, such as usability, performance, and security. Conduct unit testing to verify the behavior of individual components and integration testing to validate interactions between modules. Perform compatibility testing across different devices, screen sizes, and operating system versions to ensure consistent performance. Engage beta testers or conduct alpha/beta testing phases to gather feedback from real users and identify any bugs or usability issues .

13. Solution: 6. Deployment: Prepare the app for release by generating build artifacts, creating release notes, and completing app store submission requirements (e.g., App Store Connect for iOS, Google Play Console for Android). Coordinate with the client to schedule the app's launch, including marketing efforts and promotional activities to attract users. Monitor app deployment and rollout, addressing any issues or errors that may arise during the initial release phase.

14. Solution: 7. Maintenance: Establish a process for ongoing maintenance and support, including bug fixes, performance optimization, and feature enhancements based on user feedback. Monitor app usage metrics and analytics to identify areas for improvement and prioritize future updates and releases. Provide timely customer support and troubleshooting assistance to address user inquiries and technical issues encountered with the app. Regularly review and update the app's security measures to protect user data and ensure compliance with privacy regulations (e.g., GDPR, CCPA).
