Abstract: A device processing method and system, and a computer device and a readable storage medium. The method includes: upon acquiring configuration recommendation information for a device in a target space, which information is obtained by means of performing analysis on the basis of historical device operation data, pushing and displaying the device configuration recommendation information; in response to a selection operation for at least one device configuration item, the terminal device displaying device control information corresponding to a selected target device configuration item; and in response to a configuration operation for the selected target device configuration item, performing configuration processing on a corresponding device on the basis of the target device configuration item, wherein the device configuration item is generated according to the historical device operation data.

Abstract: A processor can produce a database catalog for a second version of a database management system of the database. The database catalog can store metadata related to definitions of objects or tables included in the second version of the database. A controller can be caused to be established in memory cells being used for the first version of the database. A copy of the database catalog for the second version of the database management system can be stored in the memory cells being used for the first version of the database. The controller, using the copy of the database catalog, can produce the second version of the database management system. The second version of the database management system can be caused to interact with data stored in a storage of the database. The storage can be included in the memory cells being used for the first version of the database.

Abstract: An adaptive modulation scheme for two streams of information that have different characteristics; preferably voice and data. The voice and data are transmitted on two quadrature channels, the I and Q channels. The amount of power in the channels is adaptively varied. The voice is given all the power it needs for reliable communication over a binary phase shift keying system. The data can have higher data rates, using an M-ary amplitude modulation scheme. The data uses whatever variable amount of power is left after transmitting the voice. The data rate is changed by changing the constellation size, so that a higher bit rate is transmitted, but requiring higher power.
