Performance analysis of the basic timestamp ordering algorithm via Markov modeling Locking and timestamping are two popular approaches to concurrency control in database systems. Although more than a dozen analytic performance studies of ... M Singhal - 《Performance Evaluation》 被引量: 24发表: 19...
The algorithm is based on a minimizing least squares method. This is to decompose the initial data table in a procedure known as "trilinear decomposition" which gives a unique solution. The trilinear decomposition comes from the model structure and sometimes data itself implies that because of its...

UUID String Algorithm UUID是通过调用 Guid.NewGuid().ToByteArray() 并且把 byte[]转换成char[],char[] 做为一个16个字符组成的字符串返回。 GUID Algorithms guid 标识符通过调用Guid.NewGuid()产生。 为了提升Guids在MS SQL中作为主键,外键和索引的一部分时的性能,可以使用guid.comb。在别的数据库中使用...
The algorithm for obtaining the process preselection mask is as follows: the audit flags from the flags: line in the audit_control file are added to the flags from the always-audit field in the user's entry in the audit_user file. The flags from the never-audit field from the user's ...
