ServiceNow application development

Here's an overview of ServiceNow application development:

1. Understanding ServiceNow Platform: ServiceNow is a cloud-based platform-as-a-service (PaaS) offering that provides a range of modules and capabilities for IT service management (ITSM), IT operations management (ITOM), IT business management (ITBM), and more. Understanding the platform's capabilities is crucial before diving into application development.

2. Application Types: ServiceNow supports different types of applications, including custom applications, scoped applications, and store applications. Each type has its own use case and deployment model.

3. Development Environment: ServiceNow provides a browser-based Integrated Development Environment (IDE) called Studio, which allows developers to build applications using a low-code approach. Additionally, developers can use traditional development tools like Visual Studio Code with ServiceNow extensions for more advanced development.

4. Data Model: ServiceNow utilizes a data model based on tables, records, and fields. Developers define data structures using tables and create relationships between them. Understanding and designing an efficient data model is essential for building robust applications.

5. Business Logic: Developers implement business logic using server-side scripting (JavaScript), client-side scripting (AngularJS), and server-side APIs. Business rules, script includes, and script actions are used to automate processes and enforce business logic.

6. User Interface (UI) Development: ServiceNow provides a drag-and-drop UI builder called Form Designer for designing forms and workflows visually. Additionally, developers can customize UI using HTML, CSS, and Jelly scripting. AngularJS and Service Portal are used for building modern and responsive user interfaces.

7. Integration: ServiceNow integrates with external systems and applications through various methods such as web services, REST APIs, JDBC, LDAP, and MID Server. Integration capabilities are crucial for building connected and interoperable applications.

8. Testing and Deployment: ServiceNow provides testing frameworks such as Automated Test Framework (ATF) for automated testing of applications. Developers can use update sets to package and deploy application changes between different environments (e.g., development, testing, production).

9. Security and Governance: ServiceNow enforces security and governance through access controls, roles, and permissions. Developers should adhere to best practices for securing applications and comply with regulatory requirements.

10. Documentation and Best Practices: ServiceNow provides extensive documentation, developer guides, and best practices for application development. Following these resources ensures that developers build high-quality and maintainable applications.

Before diving into ServiceNow application development, it's beneficial to have a solid foundation in certain skills and knowledge areas. Here's a list of skills that can help you excel in ServiceNow development:
