A saturated buffer is an area of perennial vegetation between agricultural fields and waterways where tile outlets drain. . Conventional Tile Outlet Tile Outlet with Saturated Buffer. CS 346. Outline. CS346-level Buffer Manager Background. Three Important Algorithms. QLSM Model. DBMin. Algorithm. Experiments. Buffer Managers. Buffer manager intelligently shuffles data from main memory to disk: . A . buffer is a contiguous allocated chunk of memory. , such as pointers, arrays, lists, etc.. Languages like C and C++ do not feature automatic bounds checking on the buffer, so it can be bypassed..
