A computer number format is the internal representation of numeric values in digital computer and calculator hardware and software. Normally, numeric values are stored as groupings of bits, named for the number of bits that compose them. The encoding between numerical values and bit patterns is chosen for convenience of the operation of the computer; the bit format used by the computer's instruction set generally requires conversion for external use such as printing and display. Different types of processors may have different internal representations of numerical values. Different conventions are used for integer and real numbers. Most calculations are carried out with number formats that fit into a processor register, but some software systems allow representation of arbitrarily large numbers using multiple words of memory.
A greenplum database migration method and device
ActiveCN115510023BDatabase management systemsDatabase distribution/replicationData informationTheoretical computer science
The application relates to the technical field of computer coding software, and particularly provides a Greenplum database migration method, wherein a Greenplum plug-in is uploaded in a Yunxi migration platform, database connection information is configured, a data transform plug-in is matched, data transmission between the Greenplum database is realized, and data information is encrypted and then decrypted for use. Compared with the prior art, the application has more application scenarios, is more widely used, and is more perfect in adaptation. Further market demands are met. According to the syntax rules and characteristics of different databases, specific syntax trees and mapping schemes are provided, automatic recognition is completely realized by using a program, and automatic matching conversion is carried out according to the syntax. The latest version of the syntax of each database is matched, so that the accuracy and timeliness of the tool are guaranteed.

Method for infinitely compressing and storing data
The invention discloses a method for infinitely compressing and storing data, which comprises the following steps of: 1, forming a string of ultra-long messy codes only consisting of 0 and 1 by using computer probability messy codes, and then carrying out coding statistics on sound, picture and character symbols and letters expressed by data evolved by the computer 0 and 1; the codes are GBK codes or UTF-8 codes; 2, each special symbol obtained through statistics is expressed in a combination mode of 0 and 1; 3, substituting the expression record storage system into codes, and carrying out segmented storage; according to the computer coding principle, a specific symbol form is input through the system, automatic identification is carried out in the system, then positions of super-long messy code strings are searched out, and then P is output. According to the method, the storage space can be reduced to only dozens of bytes by utilizing the characteristics of pi, and the overall value of data is not influenced while a data result is obtained.

Policy-code for data assets and repairs in cloud environment
A system (100; 200); a support method (300, 400, 500-700) and a support method (300, 400) can receive (302) a computer-encoded policy for execution in a control plane associated with a cloud environment to provide data governance in a data plane using one or more data assets of the cloud environment, wherein the one or more data assets are automatically associated (310) to the computer-encoded policy using a set of predetermined rules associated with the computer-encoded policy and using annotations associated with the one or more data assets, and wherein dynamic changes (404) are performed on the annotations based in part on real-time changes to the computer-encoded policy, the one or more data assets may be monitored (406) to allow the content of the one or more data assets to be monitored (406) in accordance with the computer-encoded policy and a repair action associated with the one or more data assets to be performed (412) in response to a violation associated with the computer-encoded policy.
