Final answer:
If all departments maintain their own database and systems, problems such as data inconsistency, data duplication, and a lack of integration and collaboration between departments can occur.
Step-by-step explanation:
One type of problem that could occur if all departments maintain their own database and systems is data inconsistency. This means that different departments might have different versions of the same data, leading to confusion and errors.
For example, if the marketing department and the sales department both have their own databases of customers, they might have conflicting information about a particular customer's contact details or purchasing history.
Another problem is data duplication. Each department might create their own separate database, resulting in redundant and duplicated data. This can lead to wasted storage space and increased costs for managing and maintaining multiple databases.
Lastly, there could be a lack of integration and collaboration between departments. If each department has their own database and system, it becomes difficult to share and access information across different departments.
This can hinder effective communication and coordination between teams, leading to inefficiencies and delays in decision-making.
