Abstract: A data transmission method suitable for transmitting a first data table from a server to a mobile device is provided, wherein the first data table has a plurality of first data fields. The data transmission method includes following steps. A maximum used bit number of each of the first data fields is identified, wherein when the maximum used bit number of one of the first data fields is 0, the first data field is deleted so as to form a second data table. The second data table is then transmitted to the mobile device.

Abstract: A database transforming method suitable for transforming a first database of a host into a second database of a mobile electronic device is provided, wherein the first database has a plurality of original fields. First, a plurality of main fields and a composite field are created in the second database. The main fields are respectively corresponding to at least one of the original fields. The main fields and the composite field are used for displaying data in the original fields. Data displayed in the composite field is separated by separators. Next, data in each field of the first database is written into the corresponding main field or the composite field of the second database. In addition, a compressible database structure and a database transforming system are also provided in the present invention.

Abstract: A method and a system for maintaining efficient material inventory are proposed, in which data related to material stock and product orders from overseas manufactories of an enterprise are stored into a database server through a network such as internet or intranet, and the stored data are processed and integrated to generate a report of current material inventory conditions, so as to manage and procure materials according to the report for maintaining safe material inventory. This allows the enterprise to immediately monitor and control material stock quantity in its manufactories, so as to maintain sufficient material inventory for supporting prompt and timely product delivery in response to client orders, and to effectively organize and manage material stock of the manufactories for reducing capital costs.
