The DBX framework (dbexpress Framework ) has been used for a long time, has always felt simple and easy to use, but today need to even MySQL5.7, found that there is no way of using it, feel it is time to give up using it for data connection.
Used to use it for C/S, three layer of development, really some reluctant to give up, but no way! In the future even the database is to use FIREDAC, after all, the various databases have been constantly updated version, FIREDAC also will continue to update and improve, and DBX in the database connection this block is no longer updated.
However, although the DBX connection to the database is outdated, but it still plays an important role in the DATASNAP system, at present, there is no fundamental change in the datasnap, everything is based on dbx things as the pillar. Perhaps one day the Indy series communication is no longer used internally, but this does not affect the location of the DBX.
Firedac in the Datasnap is still focused on the database connection, not like SqlConnection can right-click directly generate proxy class. Although fdconnection can also connect to Datasnap Server, in the FIREDAC, it is also using DBX to fetch data (at least for now) and then to FD data, so care about efficiency, or DBX is more efficient. About the inconvenient problem, benevolent see it.
