refactoring databases

Note: This essay is inspired by the "Refactoring and Patterns" section seventh, section 7.6, with the command to replace the conditional scheduler.For command not to do too much explanation, here I looked for two examples, for some of the garden friends to see: command Example 1 command Example 2.Conditional Scheduler: My understanding of this noun is that it is a relatively simple combination of the choice structure and the relatively independent bu

In this case, it is common to use the "refinement class" approach to separate part of the responsibility. If a class becomes "irresponsible", it is generally used in an "inline class" approach to incorporate it into another class. If a class uses another class, it is g

The PHP framework can be a single entry, fully object-oriented, completely based on the MVC pattern of classes. However, we face a large number of old code, or even the new code, is not entirely consistent with object-oriented principles, consistent with design patterns. Small application is no harm. But if the face of large-scale applications, it must be a big pain!! What to do? A lot of people always face this, PHP code needs refactoring. (Of course

Try not to use public. For classes or methods that must be made public, make sure they are at least one of the following:A. Data objects, including databases and script templatesB. unified access portal for public modulesC. Protocol definitions for broad scopes such as

PHP talks about refactoring-improving the design of existing code-5 simplifying function calls. The mind map introduces several articles in the previous series. I pay more attention to one of PHP's Miscellaneous "refactoring-improving the design of existing code" to reorganize your function, but I don't think I can clarify the mind map. Introduction Which of the first few articles I pay more attention?

I generally use strongly typed languages, such as Java or C + +. But I know a lot of systems are using weakly typed scripting languages, like watercress. I've tried weak type development, but it's hard to maintain later, and it's almost impossible to refactor. Is there any other way to avoid this problem, or can it support a robust refactoring? I have been on the dynamic language Building system Maintenance mode is more curious, ask the great God enli

System refactoring requires that every step of code modification cannot change the external behavior of the software. Therefore, all methods in system refactoring are equivalent changes of code. The reconstruction process is like performing an equivalent transformation of the formula step by step in a mathematical problem. After a series of equal transformation, although the final result is different from t
