What is the result of losing DBMS in a 911 system?

Losing the database management system (DBMS) in a 911 system primarily impacts the Automatic Location Identification (ALI) information, which is crucial for emergency response operations. ALI is responsible for associating a caller's phone number with their physical address and location data. When the DBMS is compromised, this critical information may be unavailable or lost, leading to delays in dispatching emergency services or providing inaccurate location information to responders.

While loss of call volume data, geographic information, or billing data are significant issues, they do not directly affect the immediate capability to locate and respond to an emergency call, which is the core purpose of the 911 system. Therefore, the inability to access precise location details—captured by ALI—is the most critical consequence of losing the DBMS in a 911 system. This can have serious repercussions for public safety, making it crucial that this data is preserved and backed up effectively.
