FreeDAC has above 60 options, controlling almost all aspects of data access functionality: fetching rows, updating rows, resources usage and data types handling. The option values are inheritable from manager (top level component) to connections and datasets.

So, FreeDAC users can decide how they will control library behaviour - in centralized way or in specific way for each dataset or how else. Here you can see options editors, as they are in FreeDAC ADExplorer:

And we constanly adding new options and optimizing existing set. So, FreeDAC users are always almost unlimited in theyr control on data access.
