You may know that Version 6 of EnCase keeps the majority of data in memory, which gives you fast access to the evidence items in a case, but is not conducive to handling large data sets. In addition, keeping most data in memory requires that records and entries be handled separately.
EnCase Version 7 behaves in a similar way to a database in that working through multiple evidence items is accomplished using an iterator. This makes for more stable processing and allows the EnScript programmer to handle both entries and records in a more streamlined way. It is possible, for instance, to iterate through all of the evidence items in a case (entries and e-mail attachments, for instance), quickly identifying those items that are pictures or documents.
