Abstract: Methods and systems for data management are disclosed. With embodiments of the present disclosure, data files originating from the same source data can be de-duplicated. One such method comprises calculating one or more of a first characteristic value for first data in a first format, and one or more second characteristic values for one or more data in one or more second formats into which the first data can be converted, said characteristic value uniquely representing an arrangement characteristic of at least part of bits of data in a particular format. The method also includes storing one of the first data and the second data in response to one of the calculated characteristic values being the same as a stored characteristic value corresponding to a second data.

Abstract: A dependency between a program to be deployed in a node in a cluster and other programs to be deployed in the cluster is obtained by one or more processors, which also obtain an IP address and connection information of a sub/pub server. A client computer connects to the sub/pub server, and subscribes to the sub/pub server for a message describing other programs on which the program is dependent. In response to obtaining the message of other programs on which the program is dependent from the sub/pub server, the program is deployed.

Abstract: Disclosed are computer implemented methods, computer program products, and computer systems for storing a file into a storage system. An embodiment includes, responsive to a determination that a descriptive information describing content of a first file corresponds to a descriptive information describing content of a second file, that a format of the first file is convertible to a format of the second file using a transformation matrix, and that the format of the first file has a higher quality indicator value than the format of the second file, storing the first file into the storage system.
