Otherwise, increase the server pressure, and torture the user's wallet.Browser caching mechanism Access the page, request various resources, and the browser checks to see if there is a cache locally. If so, check if the resource is out of date. W

If ViewGroup is selected, for example, RelativeLayout, if LinearLayout can be used in the layout, select the LineaLayout layout as much as possible. If FrameLayout can be used,

only take the corresponding referenced relationship R in the existing primary key value. ④ user-defined integrity (user-definedintegrity): User-added restrictions user-defined integrity is based on the requirements of the application environment and the actual needs of a specific application of the data involved in the binding conditions. This constraint mechanism should generally not be provided by the application, but should be defined and tested by the relation

Frontend Performance Optimization-mobile browser optimization policy and frontend Performance Optimization Summary: Front-end performance optimization is a very broad concept. The previous sections of this book also mention more or less some front-end optimization methods,

Usually SQL database needs optimization analysis, and there are some techniques, SQL optimization of several methods here do not do a detailed introduction, this article will be summarized in SQL statement optimization, followed by an optimization tool SQL Tuning Expert for Oracle and the use of methods, First, we need

1)group by group conversion (MySQL not supported ) ① group Operation Move Down GROUPBY operations may significantly reduce the number of relationship tuples, and if a relationship can be grouped before a connection between tables, it is likely to increase the efficiency of the connection. This optimization is done in advance of the grouping operation. The meaning of the move Down is that in the query tree, the grouping operatio
