Database tuning in JIRA system maintenance involves optimizing database queries to improve performance by reducing execution time and resource consumption.

JQL (JIRA Query Language) is specifically designed for querying and filtering issues within JIRA, aiding reporting.

Adding conditions to workflow transitions allows for controlling when a transition is available based on specific criteria, such as issue fields, user roles, or statuses. This helps in ensuring that transitions occur only when certain conditions are met, thus enforcing business rules and maintaining data integrity in the workflow.

In JIRA, selecting "Save" finalizes the changes made to the issue and publishes it immediately, making it visible to other users. On the other hand, choosing "Save As Draft" saves the changes without publishing the issue, allowing users to continue working on it privately. This distinction is crucial when users need to make incremental changes to an issue without affecting its public visibility. It enables users to draft and review changes before making them visible to others.

JIRA Automation Rules can help reduce manual effort in your project by automating repetitive tasks and streamlining workflows. This can lead to increased productivity and reduced chances of human error.

In JIRA, you can trace the relationship between linked issues by running a custom JQL (JIRA Query Language) query. JQL allows you to search for issues based on various criteria, including issue links. By specifying the appropriate JQL query, you can identify issues that are linked to a particular issue or issues that are linked in a specific way. This provides a powerful means of tracing relationships between issues and gaining insights into their dependencies and connections within the JIRA environment.

Agile emphasizes delivering incremental value to customers frequently, allowing for rapid feedback and adaptation based on customer needs and market dynamics, thereby enhancing overall project success.

The correct option is "Scrum framework". The Scrum Master ensures that the Scrum Team adheres to the principles and practices outlined in the Scrum framework, facilitating the team's progress and adherence to its processes.

When creating a sub-task in JIRA, you can specify its type and summary. These attributes help define the nature of the sub-task and provide a clear understanding of its purpose within the parent issue.

JIRA integrations often rely on APIs, which stands for Application Programming Interfaces. APIs provide a way for different software applications to communicate with each other. In the context of JIRA, APIs allow for integration with other tools, automation of tasks, and customization of workflows, enhancing the overall functionality and interoperability of the system.
