Abstract: In a database accessing method using an electronic device having a database, character fields and corresponding attributes are predefined. An entity object including the character fields is generated and provided to a client device for inputting business data. After receiving an encapsulated entity object from the client device, the business data including selected character fields, corresponding character data, and an operation request for the database are acquired. When the database includes a data table and the data table includes the character fields corresponding to the selected character fields, the selected character fields and the character data of the selected character fields are verified. When the selected character fields and the character data of the selected character fields are valid, character data of the character fields corresponding to the selected character fields are updated using the character data of the selected character fields according to the operation request.

The plurality of bitstreams in the encoded file comprising a plurality of enhancement layers. According to a selection of a user of the electronic device, a snapshot grade is determined. According to the received bitstreams and the determined snapshot grade, additional enhancement layers which are not comprised in the received bitstreams are acquired from the encoded file in the server through the network channel. Based on the acquired additional enhancement layers, a video snapshot is generated.

Abstract: In a method of error recovery when downloading data files using an application server, the application server connects to at least one terminal device and several file servers. The application server receives a file downloading request from the terminal device, finds a first file server nearest to the terminal device, and downloads the required data file from the first file server to the terminal device. The application server searches a file configuration table to find a second file server which is away from the first file server when the data file has not been successfully downloaded from the first file server, downloads the required data file from the second file server to the terminal device, and synchronizes the data file of the second file server to recovery the data file of the first file server when the data file has been successfully downloaded from the second file server.

Abstract: A monitoring server receives the latest monitored data and corresponding monitoring time from monitoring devices connected to the server at a specified time interval. The monitoring server records monitored data of each monitoring item and the corresponding monitoring time to a pointed node of a device data list, and adds the monitored data and the corresponding monitoring time, which are recorded in the pointed node of the device data list, into a monitored data list. When a web server requests real-time monitored data, corresponding monitored data is read from the device data list and sent to the web server. When the web server requests historical monitored data of an designated period, corresponding monitored data of the designated period is read from the monitored data list and sent to the web server.

Abstract: In a method for processing an image file using a computing device, an image file from a storage system is read. If an image in the image file is slanted, an incision coordinates according to a configuration file in the storage system and a preset formula is calculated. The method incises the image using the calculated incision coordinates and storing the incised image in a new image file. If an image in the new image file is not slanted, the method further determines whether the image has been incised. If the image has been incised, the method records the calculated incision coordinates that make the image not be slanted as optimal incision coordinates, and stores the optimal incision coordinates into a database.
