As we'll see in Chapter 12, the new multi-tier architecture of Delphi 2009 is based on the use of datasets, records, and fields, both for passing parameters and results. This is why Delphi 2009 has many new field types, which are not strictly meant for direct database processing. The new field types are:
ftLongWord, ftShortint, ftByte, ftExtended, ftConnection, ftParams, ftStream
While the first four represent language data types, the last three are clearly meant for transferring higher level data structures (database connections, parameters, and streams).
