Demo_Chart_WebGrid

Two Part:

(1) design a table for test, create a view or procedure and input some records for test.

(2) use the view or procedure of the database, design a image by the class of chart and display all the data by the help of WebGrid.

Note: the Part(1) designed is to test and you can use the same method in the database of  you computer or server.

In this demo use the view of database.

Part(1) Database

1.Oracle SQL Developer

1.1 USE THE URSR SCOTT,CREATE TABLE METRICS and input some data (ID IS PK), you can copy them from the PR_SUM.XLS

1.2 Open the METRICS input the data and ensure it.

1.3 Use the ROLE OF SYSDBA  TO CREATE VIEW and    Scheme （方案）： SCOTT ,  VIEW_SUM

2.MVC+ORACLE+ODAC(use the view of database )

in the HomeController.cs  In the HomeController, the Action Index
