The invention provides a data de-duplication method for combining the similarity and the locality of data, with less system memory expense and high data de-duplication efficiency. The method comprises the steps of: firstly partitioning and grouping files in a data stream, determining a similarity unit and a representative fingerprint of every data group, and storing the representative fingerprint in a memory; and traversing all the data groups and performing a similarity determination to determine which data in data groups are completely duplicate data and which data in data groups have non-duplicate data. If the non-duplicate data exists in the data groups, the locality determination can be continued to further determine which data in the data groups is the duplicate data. According to the method, the representative fingerprint is only stored in the memory, thus the memory expense is greatly reduced; supplement can be performed after the similarity determination by mining the locality of the data stream and caching the locality of the data stream in the memory, thus more duplicate data can be found, and simultaneously, frequent access to a disk index can be avoided and the utilization rate of the memory can be enhanced.

The embodiment of the invention provides an object deletion method and a terminal, relates to the technical field of electronic terminals and can solve the problem in the prior art that a picture deletion operation step is complex. The method comprises the following steps that: the terminal receives a first gesture operation instruction; the terminal determines whether a gesture indicated by the first gesture operation instruction is a preset deletion gesture or not, wherein the deletion gesture is used for indicating an object in the deletion terminal, and the trajectory of the preset deletion gesture comprises a contact which generates a continuous trajectory, the trajectory meets at least one of prediction conditions, and the preset condition comprises that: an included angle between the trajectory and the screen boundary of the terminal is greater than or equal to a first preset threshold value; operation speed corresponding to the trajectory achieves a second preset threshold value; touch dynamics corresponding to the trajectory achieves a third preset threshold value; if the trajectory meets at least one preset condition, the terminal determines an object to be deleted, the object to be deleted is segmented into at least two parts, and the at least two segmented parts are displayed in the user interface of the terminal.

The invention discloses an aggregate big file deletion method. The method comprises the steps of scanning an aggregate big file in an aggregate directory, and when the size of an invalid storage spaceis greater than a preset space threshold, adding the aggregate big file corresponding to the invalid storage space to a cleaning queue; according to identifiers corresponding to small files in the currently cleaned aggregate big file, judging whether the small files are to be reserved or not, and after the to-be-reserved small files are determined, writing the to-be-reserved small files in a newaggregate file; and when all the small files are traversed, deleting data in the aggregate big file and moving the aggregate big file out of the cleaning queue. When the size of the invalid storage space of the aggregate big file is greater than the preset space threshold, the to-be-reserved small files in the currently cleaned aggregate big file are written in the new aggregate file, then the aggregate big file is deleted, and the disk space is released, so that the disk utilization rate is increased. The invention furthermore discloses an aggregate big file deletion apparatus and device, anda computer storage medium.

The invention provides a method and device for deleting the content of user equipment and the user equipment.

The invention provides a database read-write method for mass performance data of a network management system. The method is characterized in that when a database is established, a partition data table is defined for storage of the data, partitioning is performed by date with days being granularity, and a partition table maintenance component is used for increasing a new partition and deleting an overdue partition; when the data is written in, the database allocates the data into different partitions according to a defined partition range, and the data is subjected to format compression first and then written into the database; when the data is read, the data is filtered from multiple partitions in parallel, and after format decompression is performed, a result is returned to the network management system. According to the technical scheme, the database read-write efficiency can be improved under the mass performance data by scattering data storage, lowering the data reading size and increasing the data reading parallelism degree.

The invention provides a deleting control method and device for an intelligent television text, wherein under the state that a simulation keyboard is called out, the method comprises the steps of receiving and analyzing a first control signal; if the first control signal indicates that a delete key on the simulation keyboard obtains an operation focus, moving the operation focus to the delete key; receiving and analyzing a second control signal; in the second control signal indicates that the delete key on the simulation keyboard is triggered to delete characters on a textbox, judging whether the triggering of the second control signal accords with a preset rule, wherein the preset rule defines conditions for deleting all or part of the characters correspondingly; if the judging result is yes, performing the delete operation on the characters of the textbox.
