What are the effects of setting IsolationLevel transaction property of a Data Flow task to Chaos?
A. It prevents pending changes from more highly isolated transactions from being overwritten B. It prevents shared locks from being issued and exclusive locks from being honored. C. It prevents other users from updating the data. D. It reduces blocking by storing a version of data that one application can read while another is modifying the same data.
The data flow task cocoons the data flow engine that shifts data between sources and targets and lets the user convert, clean, and modify data as it is moved. Incorporation of a data flow task to a container control flow makes it feasible for the package to remove, transform and load data.
An information flow consists of at least one data flow element, but it is typically a set of connected data flow sources that extract data. If a task copies many sets of data, and if the order in which the data flows in the data flow task.
