Software Development and Management

The correct applet lifecycle follows this sequence: init() (initialization), start() (begins execution), paint() (rendering), stop() (pauses execution), and destroy() (cleanup). This order ensures proper initialization before execution and proper cleanup before termination.

J2EE supports multiple client types: Applets (browser-based Java clients), Application Clients (standalone desktop apps), and Wireless Clients (mobile devices). All three are valid J2EE client categories.

RMI development involves multiple steps: defining the remote interface that extends Remote, implementing that interface in a remote object, compiling the interface and implementation using rmic to generate stubs and skeletons, and then registering the object with the RMI registry. All these steps are necessary.

EAR (Enterprise Archive) files contain EJB modules along with other application components like web modules (WAR files) and utility JARs. The EAR format packages all modules of a Java EE enterprise application.

Solution packages have a limitation - they cannot deploy files to folders outside the SharePoint 12 hive (the installation directory structure). The other options listed are advantages: easy multi-server deployment, automatic web.config updates, and automatic deployment to new farm servers. The 12 hive restriction is a structural limitation of the solution framework.

SAP stands for Systems Applications and Products in data processing. It is a German enterprise software company that develops ERP (Enterprise Resource Planning) software used by businesses to manage operations and customer relations.

In MVC (Model-View-Controller) architecture, the Model represents the business logic and data layer. It encapsulates the application's data, business rules, and validation logic, independent of how the data is displayed or processed.

MVC architecture separates concerns into three components, making it easier to modify the user interface (View), control logic (Controller), and business logic (Model) independently. This separation also promotes code reuse and helps developers avoid repeating common code across the application.

In MVC architecture, the Model represents the business logic and data layer. It handles data validation, business rules, and data access operations. The Model is independent of the UI (View) and user interaction handling (Controller).

MVC separates concerns into Model (business logic), View (UI), and Controller (control logic). This separation makes it easy to add/edit/remove interfaces (View changes), modify control logic (Controller changes), and avoids code repetition through reusable components.

FRD Review requires multiple inputs to validate requirements comprehensively. Wireframes provide UI/UX visualization, prototypes show interactive mockups, and use cases describe functional scenarios. All these artifacts serve as inputs for the review process to ensure requirements are testable, complete, and aligned with user needs.

Dependency injection is a design pattern where objects receive their dependencies from external sources rather than creating them internally. This promotes loose coupling, easier testing, and better code maintainability by allowing dependencies to be swapped or mocked.

Spring framework defines multiple bean scopes. Singleton (default) creates one instance per Spring container, while prototype creates a new instance each time the bean is requested. Additional scopes like request, session, and application are available in web contexts.

Service-Oriented Architecture is a software architecture style where application components provide services to other components through network protocols. It emphasizes loose coupling, reusability, service abstraction, and is often implemented using web services.

Service-Oriented Architecture emphasizes key principles: reuse services across applications, build modular services, and componentize functionality into discrete services. While inheritance is an object-oriented programming concept, it's not a core SOA guiding principle.
