I recently learned the basic principles of the vue framework and read some technical blogs and some simple implementations of the vue source code, provides a deeper understanding of data proxy, data hijacking, template parsing, variant array methods, and bidirectional binding. As a result, I tried to practice what I learned and use some basic principles of vue to impl

Some questions: 1. The difference between inserting data in a heap table and inserting data in a clustered table results in what happens when the data is inserted in a clustered table based on the primary key (Data page, index page, page split) 2. Even if there is an index, and you can find the data by index Lookup + bookmarks, sometimes the table is scanned. That is, table scans and index scans, the performance of index lookups, and the choices that sometimes are uncertain should try to avoid c

Emberjs is used to create a simple Todo application to achieve the following effect: Input text in the text box and create an event handler. You can select a priority for the event handler and delete the completed event.
Preparation To complete this application, you need to prepare:1. Create an html page, regardless of the style;2. Script: emberjs, handlebars, and jQuery. These three scripts can be obtained from the Internet. We will add them
