*Data preperation

*Algorithim computation

Data management refers to a set of operations that work on the data and are distributed between the stages of the data analytics pipeline. The data management flow is shown in the figure below. You start with your raw data and its acquisition. The first step is to transfer the out of memory data, the source could be from files, databases, or remote storage, into an in-memory representation.

The third step is to stream the in-memory numerical data to the algorithm

In complex usage scenarios the data ends up going through these three stages back and forth, so for example if your data isn’t fully available at the start of the computation it can be sent in chunks which is an advantage of DAAL I mentioned earlier.
