5. What is the full form of CMDB?

The term “CMDB” stands for Configuration Management Database. Within the domain of IT service management, a CMDB serves as a centralized repository that stores specific information about an organization’s configuration items (CIs). These encompass various elements of the IT infrastructure, such as hardware devices, software applications, and network components. The CMDB’s primary function is to provide a structured and comprehensive database that effectively tracks the relationships and dependencies among different CIs. By maintaining accurate and current records of IT assets, the CMDB plays a pivotal role in facilitating essential IT service management processes like incident management, change management, and problem management.

6. What is the CMDB Baseline?

The CMDB Baseline refers to a predetermined snapshot or reference state of the Configuration Management Database (CMDB) that represents the desired and approved configuration of an organization’s IT infrastructure. It encapsulates all the configuration items (CIs), their attributes, as well as the relationships and dependencies among them.

date and time value. Subsequently, save the modifications made. As a result, the date field will consistently populate with the present date and time information whenever the form is accessed.

10. How will you hide/show a field using a Client script?

To conceal or reveal a field using a client script in ServiceNow, observe the subsequent steps. Firstly, identify the targeted field that necessitates hiding or showing.
