Final answer:
A single database poses issues such as a single point of failure, performance bottlenecks, security risks, challenges in scalability, and a lack of data segregation, all of which can adversely affect the entire organization.
Step-by-step explanation:
Having a single database that supports an entire organization can lead to several issues. One of the main concerns is the single point of failure, where if the database goes down due to technical issues or cyber-attacks, the entire organization’s operations can be halted. Another issue is performance bottlenecks; as the number of users increases, the workload on a single database can cause slowdowns and hamper the efficiency of operations. Furthermore, there might be security risks as a single database is a tempting target for malicious activities, and if breached, can compromise the entire organization's sensitive information.
Also, scalability becomes a challenge with a single database setup because it might not handle the growing data and user load effectively. Finally, the lack of data segregation might cause conflicts, as different departments or teams within the organization have varying data access and manipulation needs, and a single database might not be able to accommodate these needs without compromising on operational efficiency or security.
