Right Answer: A lookup file is a static reference file used to retrieve additional information based on a key value during data processing. It is typically smaller and used for quick lookups. A join, on the other hand, combines two or more datasets based on a common key, merging their records into a single output. The key difference is that a lookup file is used for referencing data, while a join is used for combining datasets.
Right Answer: I stay updated by following industry blogs, subscribing to newsletters, participating in online forums, attending webinars and conferences, taking online courses, and engaging with developer communities on platforms like GitHub and Stack Overflow.
Right Answer: The RTE (Runtime Environment) in Classic AUTOSAR acts as a middleware layer that facilitates communication between software components (SWCs) and the underlying hardware. It manages data exchange, service calls, and ensures that SWCs can operate independently of the underlying hardware and other SWCs.
Right Answer: Compiled languages are converted into machine code by a compiler before execution, resulting in faster performance. Interpreted languages are executed line-by-line by an interpreter at runtime, which can lead to slower performance.
Right Answer: Continuous Integration (CI) is the practice of frequently merging code changes into a central repository, where automated builds and tests are run. Continuous Deployment (CD) is the practice of automatically deploying every change that passes the tests to production.
Benefits of CI/CD include:
1. Faster development and release cycles.
2. Early detection of bugs and issues.
3. Improved collaboration among team members.
4. Higher quality software with fewer defects.
5. Reduced manual work and deployment errors.
Right Answer: An overcurrent relay is a protective device that detects excessive current in an electrical circuit and triggers a disconnection to prevent damage to equipment.
Right Answer: The roles and responsibilities of a Team Leader include:
1. **Guiding the Team**: Providing direction and support to team members.
2. **Communication**: Facilitating clear communication within the team and with other departments.
3. **Performance Management**: Monitoring team performance and providing feedback.
4. **Conflict Resolution**: Addressing and resolving conflicts within the team.
5. **Training and Development**: Identifying training needs and facilitating skill development.
6. **Goal Setting**: Setting team goals and ensuring alignment with organizational objectives.
7. **Motivation**: Encouraging and motivating team members to achieve their best.
8. **Reporting**: Providing regular updates and reports to higher management.
Right Answer: The requirement of a hospital pharmacy includes ensuring the safe and effective use of medications, managing medication inventory, providing pharmaceutical care to patients, collaborating with healthcare professionals, and complying with regulations and standards.
Right Answer: WMS stands for Warehouse Management System, which is software that helps manage and optimize warehouse operations, including inventory tracking, order fulfillment, and shipping processes.
Right Answer: OAuth is an open standard for access delegation commonly used for token-based authentication and authorization. It allows third-party applications to access a user's resources without sharing their credentials.
In API authentication, OAuth works by having the user authorize the application to access their data. The process involves:
1. The user is redirected to an authorization server to log in and grant permission.
2. The authorization server issues an access token to the application.
3. The application uses this access token to make API requests on behalf of the user.
4. The API validates the token and grants access to the requested resources.
Right Answer: API versioning is the practice of managing changes to an API by assigning version numbers to different iterations of the API. It is important because it allows developers to introduce new features or make changes without breaking existing client applications that rely on older versions, ensuring backward compatibility and a smoother transition for users.
Right Answer: CORS, or Cross-Origin Resource Sharing, is a security feature implemented by web browsers that allows or restricts web applications from making requests to a domain different from the one that served the web page. It affects API development by requiring developers to configure their APIs to specify which origins are allowed to access their resources, ensuring that only trusted domains can interact with the API.
1. **Open APIs (Public APIs)** - Available to developers and third parties.
2. **Internal APIs (Private APIs)** - Used within an organization.
3. **Partner APIs** - Shared with specific business partners.
4. **Composite APIs** - Combine multiple endpoints into a single call.
5. **Web APIs** - Accessible over the internet using HTTP/HTTPS.
Right Answer: A web service is a standardized way of allowing different applications to communicate over the internet using protocols like HTTP. It provides a method for applications to exchange data and perform operations. An API (Application Programming Interface) is a set of rules and tools that allows different software applications to interact with each other. A web service is a type of API that specifically uses web protocols to enable this interaction.
