Comparison of software versions -- Comparison of Java Algorithm Implementation Software Versions
Recently, I encountered a small problem in development. The software version is compared: for example, 2.12.3 and 2.2.1.
In fact, the Client Version is updated to check whether t
In SQL Server, the software version number is compared to the character string. in SQL, the version numbers such as 1.2.1.571.2.12.57 are compared directly. In this case, a downconversion is required to convert 1.2.1.57 to 00001000020000100057 for comparison. [fun_split_version] is used for comparison. createfunction [dbo]. [fun_spl

Then, through feedback from customers or users, we will gradually improve this "imperfect outcome.Spiral developmentTo a large extent, it is a risk-driven method system, because risk assessment must be carried out before each stage and before frequent loops.Agile development,Compared with iterative development, both emphasize submitting

Then through the customer or user feedback information, in this "imperfect fruit" on the gradual improvement.
Spiral development is, to a large extent, a risk-driven approach, because risk assessments must be conducted before each phase and before the recurring c
