It should be said about Mobile2.0 There are two main versions, one is Mobile Web 2.0, Web2.0 is the mobile version, put it on the phone; a mobile application is a new level, relative to the previous application (1.0), this new level called Mobile2.0. But in fact, both views are not contradictory, because the mobile version of Web2.0 mobile applications can be seen as a new level, so the second argument is that including the first of.
optimized DATA MANAGEMENT to mobilize your business Birdstep RDM Mobile 2.0 A robust, reliable database specifically designed for wireless applications requiring ultra small footprint, minimum runtime memory usage, and high performance. RDM Mobile is ideally suited for portable devices such as Smart Phones, PDAs, and Electronic Notebooks. Why Developers Choose Birdstep RDM handling implemented with full respect of the Mobile “ACID” database properties. • Multiple Attribute Types – The developer RDM Mobile 2.0 is the database of choice for has flexibility to define their database that best mobile application developers. With its rich optimizes their design goals. feature set, small size and supported platforms, • Text Representation – RDM Mobile utilizes RDM Mobile provides a superior data its object-oriented data structure to store text management platform for mobilizing business strings in variable-length fields. Thus, RDM critical applications. Mobile reaches a far better storage utilization than the comparable classic solutions. Mobilizing Business Critical Applications • Memory Mapped Database – The RDM Mobile database manager supports all Developers choose RDM Mobile for wireless common types of persistent storage, including applications where size matters, memory is flash drives. The manager provides seamless limited, and performance is essential. RDM mapping of the underlying medium to the Mobile has been designed from the start for memory, simplifying the use from the user mobile application developers. This means that space and improving efficiency at the same RDM Mobile has very efficient indexing time. algorithms to ensure fast look-up of data even on • Multiple Operating Systems Supported – systems with severely limited system resources.
