The disclosure facilitates management of a plurality of related data stores by tracking metadata changes across the data stores, detecting the impact of the tracked metadata changes, and generating alerts based on the detected impact. Metadata change data from a plurality of data stores are received by a change impact engine and recorded to a centralized metadata change data structure. At least one change impact rule is applied to the recorded metadata change data and, upon detection of an impact based on the applied change impact rule, an alert based on the applied impact rule is generated. Consolidating the metadata change data from multiple data stores and detecting metadata changes that will significantly impact the operation of the associated system provide advance opportunities to manage and/or mitigate the impact of the metadata changes.
