Which of the following is a challenge associated with data integration in PSE Cortex?

Diverse data formats and structures present a significant challenge in data integration within PSE Cortex. In any system where data from various sources needs to be consolidated, the compatibility of these diverse formats can lead to complexity in merging and interpreting the information accurately. Different systems might use various data structures, encoding methods, or standards, which can create hurdles when attempting to integrate datasets efficiently. This challenge requires sophisticated mapping and transformation techniques to ensure that the data is harmonized and usable across platforms.

The existence of various data formats means extra steps must be taken to convert data into a consistent format that the integration system can process effectively. This process often involves data cleansing and validation as well to maintain integrity and reliability, which can add to the complexity and time required for successful integration.

In contrast, other options may not present the same level of challenge in the context of PSE Cortex. For instance, while inadequate storage space can hinder data management, it doesn't necessarily impact the integration process itself. Similarly, having a lack of available data sources may affect the volume of data but not the quality of the integration process. Excessive user permissions can introduce security challenges but do not directly relate to the integration of data formats or structures.
