will discuss general modeling techniques for a variety of nosql implementations. 1. Atomic polymerization (Atomic aggregates) Many NoSQL solutions offer limited transactional support, although some nosql do not support it. In some cases, people can also use distributed locks or application-managed MVCC mechanisms to implement transactional behavior, but it is common to use aggregation techniques to model data to ensure some acid properties. A powerful transaction mechanism is essential for rela

Using selectors and events for the jquery start-up tutorialjquery offers two ways to choose the elements of HTML:
The first is to combine CSS and XPath selectors to form a string to be transferred to the jquery constructor (for example: $ ("DIV > Ul a"));
The second is to use several methods (methods) of the JQuery object. Both of these methods can also be combined to use together.
To test these selectors, let's try to select and modify the first ordered list in our starterkit.

Getting started with jquery using selector and eventsJquery provides two methods to select HTML elements:
The first type is to combine CSS with the XPath selector to form a string to be transmitted to the jquery Constructor (for example, $ ("div> ul "));
The second method is to use several methods of the jquery object ). These two methods can also be combined for hybrid use.
To test the selection, we try to select and modify the first ordered in starterkit.html.List.
