Abstract

A method is provided for initializing an XML database. The method includes the steps of parsing an XML file to extract a plurality of records, the records arranged in a hierarchical form, creating, for each record, a plurality of class objects, each class having associated therewith one or more attributes, and creating a plurality of handling methods for each of one or more attributes associated with each class object, the handling methods defining how the database can be accessed.

Claims

1. A non-transitory computer-readable medium having stored therein a set of instructions, which when executed by a computer, cause the computer to perform a method of initializing an extensible markup language (XML) database, the method comprising:

dynamically generating an empty structure for the XML database and code to access and handle objects in the XML database, the dynamically generated XML database structure and code corresponding to an XML file, the dynamically generating comprising;

parsing the XML file to extract a plurality of records therefrom, the records arranged in a hierarchical form;

creating, for each record extracted from the XML file, a corresponding class that defines a part of the empty structure for the XML database, each class having associated therewith one or more attributes of the each record; and

creating a plurality of handling methods for each of one or more attributes associated with each object within a class, the handling methods defining how data associated with the attributes can be accessed in the database.

2. The non-transitory computer-readable medium of claim 1, wherein the method further comprises:

generating an XML schema representing the hierarchical relationship among the records.

3. The non-transitory computer-readable medium of claim 1, wherein at least one of the one or more attributes describes a filename, and the file associated with the filename is stored in a separate directory than the XML file.

4. The non-transitory computer-readable medium of claim 1, wherein the plurality of class objects include at least one parent object.

5. The non-transitory computer-readable medium of claim 1, wherein the method further comprises:

determining whether a class object is a parent class, and for each parent class, creating a vector container in the class object to store the associated child objects.

6. The non-transitory computer-readable medium of claim 1, wherein the XML file is encrypted.

13. A system comprising a computer that executes the instructions stored in the non-transitory computer-readable medium of claim 1.

7. A method of initializing an extensible markup language (XML) database, the method comprising:

dynamically generating an empty structure for the XML database and code to access and handle objects in the XML database, the dynamically generated XML database structure and code corresponding to an XML file, the dynamically generating comprising;

parsing the XML file to extract a plurality of records therefrom, the records arranged in a hierarchical form;

creating, for each record extracted from the XML file, a plurality of class objects defining part of the structure for the XML database, each class having associated therewith one or more attributes of the each record; and

creating a plurality of handling methods for each of one or more attributes associated with each object within a class, the handling methods defining how data associated with the attributes can be accessed in the database.

8. The method of claim 7, further comprising:

generating an XML schema representing the hierarchical relationship among the records.

9. The method of claim 7, wherein at least one of the one or more attributes describes a filename, and the file associated with the filename is stored in a separate directory than the XML file.

10. The method of claim 7, wherein the plurality of class objects include at least one parent object and one child object.

11. The method of claim 7, further comprising:

determining whether a class object is a parent class, and for each parent class, creating a vector container in the class object to store the associated child objects.

12. The method of claim 7, wherein the XML file is encrypted.
