approach 3 The third paradigm, data cannot have a transitive relationship, that is, each attribute is directly related to the primary key rather than the indirect relationship. Like: The A-->b-->c attribute contains such a relationship that is not in accordance with the third paradigm. A school has a number of students, the first paradigm can not be achieved, the second paradigm can not be achieved, a student only belong to a school, at this time the use of the third paradigm, Design that does

Iii. JSON Mode
Json preparation knowledge:
Json is a simple data format, which is lighter than xml. Json is the native format of JavaScript, which means that no special API or toolkit is required to process json data in JavaScript. Json syntax rules are actually very simple: the object is an unordered set of 'name/value' pairs. An object starts with "{" (left parenthesis) and ends with "}" (right Parenthesis. Each "name" is followed by a ":

JSON rules are simple: the object is an unordered set of 'name/value' pairs. An object starts with "{" (left parenthesis) and ends with "}" (right Parenthesis. Each "name" is followed by a ":" (colon); "," (comma) is used to separate the "name/value" pairs. Detailed reference http://www.json.org/json-zh.html

Finally, if your code is much restricted and monitored, but in general it rarely gets into trouble in the server environment, you will be more confident during deployment.
Also, the biggest advantage of sandboxed solution is that it can be deployed by the site set administrator, and they will be deployed in the solution Gallery of the site set. Furthermore, if your solution does not require deploymentProgramAssembly, so even those who have full control over the site set can be deploy
