ZK Developer's Guide Review
The complexity in developing Ajax based applications has led some software development companies to build frameworks that would ease the workload of developers especially for those who are not familiar with JavaScript. With the help of a framework, the developer doesn’t even have to learn the complicated aspect of JavaScript. Each of the frameworks have their own technique in helping the developer but all of them in the end aid the developers build a good looking Ajax based application without the ropes of manually coding JavaScript. Some frameworks are too simple and common that they end up being ignored while some offers the functionality and robust any developer needs to build an efficient Ajax based application. |

Breaking up XML into Relational Data
While the preceding example shows how to construct an XML representation over relational data, the example in this section illustrates how you can shred XML data back into relational data. This reverse operation can be useful if your application works with relational data rather than XML, but the data which you work with, is stored in XML format. |

In fact, Oracle XML DB repository resources are stored in a set of database tables and indexes, which can be accessed via SQL. You are not supposed to access those tables directly. Instead, Oracle XML DB provides two public views RESOURCE_VIEW and PATH_VIEW through which you can access repository resources. |

Performing DML Operations on XML Schema-Based XMLType Views
Analyzing the underlying query of the empSch_v view discussed in the preceding section, you may note that each attribute of the EMP_T object used in the select list maps to a certain column of a single table, namely emps. What this means in practice is that the empSch_v view can be inherently updated, so you can perform DML operations against it without having to write INSTEAD-OF triggers. |

Using XMLType Views
Using XMLType Views XMLType views provide a convenient way to construct XML representations of relational data without physically migrating that data into XML. Once written, an XMLType view may be used in various queries, making them simpler and so increasing their readability. |

Retrieving XML DataTo retrieve XML data from an XMLType table, you can use a SELECT SQL statement, just as you would if you had to query a relational table. For example, to select the employee with the id set to 100 from the employees XMLType table discussed in the preceding section, you might issue the following query from SQL*Plus when connected as xmlusr/xmlusr: |
