What is the primary function of the Acquisition layer in data processing?

The primary function of the Acquisition layer in data processing is to serve as the point of entry for raw data through source systems. This layer is crucial because it is responsible for gathering all incoming data from various sources, such as operational databases, external sources, and other data repositories. This process ensures that all relevant data is captured before it undergoes any transformations or processing.

In the context of data processing, the Acquisition layer sets the stage for subsequent stages, such as cleansing, transforming, and loading data into target systems. It is essential for building a comprehensive data repository, as it captures diverse raw data that can later be refined and analyzed.

The other options may represent important functions within the broader data processing environment but do not directly describe the core role of the Acquisition layer. For instance, enhancing data accessibility or creating common metrics pertain more to layers focused on analysis and reporting, while standardizing raw data typically occurs after the data is acquired. Thus, while those activities are critical in the overall data lifecycle, they are not the primary function of the Acquisition layer.
