Embodiment Construction

[0057] figure 1 It is a schematic diagram of a database conversion system according to an embodiment of the present invention. Please refer to figure 1 , the database conversion system 100 mainly includes a first database 112 , a second database 122 and a database conversion module 114 . In this embodiment, the first database 112 and the database conversion module 114 are located in a host 110 , and the second database 122 is located in a mobile electronic device 120 . The mobile electronic device 120 is connected to the host computer 110 through a universal serial bus, for example, so that the second database 122 is connected to the first database 112 through the database conversion module 114, so that the data of the first database 112 can be passed through the database. The compression transformation of the library conversion module 114 is written to the second database 122 . In another unshown embodiment, the database conversion module 114 can also be located in the mob...

Abstract

The invention relates to a database conversion method, which is suitable for converting a first database of a host computer into a second database of a mobile electronic device, wherein the first database is provided with a plurality of initial fields. The method comprises: firstly, newly adding a plurality of main fields and a composite filed into the second database, wherein the main fields correspond to at least one among the initial fields respectively; the main fields and the composite field are used for displaying data in the initial fields; and data displayed in the composite field is mutually distinguished through a separator; and secondly, writing data of various fields of the first database into corresponding main fields or the composite field of the second database. From another angle, the invention also discloses a compressible database structure and a database conversion system.

Description

technical field [0001] The present invention relates to a method, system and structure of a database, and in particular to a method, system and structure of a compressed database. Background technique [0002] In today's era of information explosion, human life is inseparable from electronic information. It is quite common for users to use portable electronic devices to exchange electronic messages and store electronic data, especially mobile communication devices and Personal Digital Assistant (PDA), wherein the mobile communication device is, for example, a mobile phone or an electronic device with a wireless communication function. [0003] Generally, portable electronic devices are designed to be thinner, lighter and smaller to facilitate users to carry them. However, under the limited volume, the performance and storage capacity of the portable electronic device cannot be compared with that of the general computer mainframe. Therefore, in order to cope with the limite...
