Indexed compressed flat file or ICFF can be considered as a special kind of lookup file which can store large volumes of data without compromising quick access to individual records. Common lookup files have a limit to the amount of data one can store, which is not the limitation of ICFF. Other important features, as gathered from help: ICFFs present advantages in a number of categories: * Requires much less disk storage — as name suggests, ICFFs store compressed data in flat files without the overheads associated with a DBMS, hence requiring much less disk storage capacity than databases — on the order of 10 times less. * Requires much less memory at one time — as ICFFs organize data in discrete blocks, only a small portion of the data needs to be loaded in memory at any one time. * Comparatively much faster — ICFFs allow us to create successive generations of updated information without any pause in processing which significantly reduces the time between a transaction taking...
