Present application development is being divided by two with big extinction. On the one hand desktop application, already as for one side it is Web application. And, that several dozen vendors probably will enter, there is a field which is competitive in that rift. RIA several years, may extend rapidly future, (Rich Internet Application) is.
While the desktop application camp, showing the attitude which opposes promptly, the resource of the local machine full utilizing, complicated user interface it reached the point where it colors with beautiful decoration. But as for this in addition to the fact that installation is necessary, in order the other software not to compete, you must consider in compatibility. Especially, there are times when the case of update problem occurs in compatibility it is big demerit.
Vis-a-vis this, Web application installation being unnecessary, in addition to always utilizing in up-to-date state, can guarantee also compatibility. Defect the response to become sluggish tend thing, is the place such as the thing which is the possibility job being discontinued with problem of thing and the server side which have restriction in operation method of user interface.
RIA is the attempt which it tries to combine just these two merits. As the response is designated as high speed, in order to be able to complicate user interface according to need, the majority of interfaces is put client side. Because of that, there are times when installation job becomes necessary, but usually is just the execution time engine, as for this in addition to the fact that size is small, those of automatic update correspondence are the majority.
It starts RIA itself generally from the remote server, in many cases, intermittent connection is possible. For example, when being necessary to utilize the database, when the local machine is cut off from Internet, the local database starts. For the second time when it is connected, application the local database takes the same period of the central database.
As for me, application in the world is displaced with does not think either the minute dust in RIA. In the future the use where desktop application and Web application are suited is a certain expectation. Me as for those where you can say with self-confidence, as for RIA when burying the opening of desktop application and Web application, the technology which standardizes all application at least as for one is in thing, and final it reaches the point where more important role is carried out it appears probably to be.
It cannot judge with present time whether the technology is some kind of ones. Perhaps the causing れ which is the technology which exists already or, it is something which is born from now on. But that the writer thinks whether it does not mean that within 5 years that form becomes clear.
