XML CONFIGURATION TECHNIQUE AND GRAPHICAL USER INTERFACE (GUI) FOR MANAGING USER DATA IN A PLURALITY OF DATABASES

CROSS REFERENCE TO RELATED APPLICATIONS This application claims priority to a provisional application entitled "XML CONFIGURATION TECHNIQUE AND GRAPHICAL USER INTERFACE (GUI) FOR

MANAGING USER DATA IN A PLURALITY OF DATABASES" filed in the United States Patent and Trademark Office on July 11, 2003 and assigned Serial No. 60/486,508, the entire contents of which are hereby incorporated by reference. This application is also related to U.S. provisional application Serial Nos. 60/486,517 and 60/486,512, each filed on July 11, 2003, the entire contents of each of these applications also being incorporated by reference.

BACKGROUND 1. Field The present invention relates generally to database management systems, and more particularly, to a system and method for managing user data in a plurality of databases. Additionally, the present invention relates to an XML configuration technique and graphical user interface (GUI) for managing the user data in the plurality of databases.

2. Description of the Related Art Driven by new Internet technologies, business growth requires organizations to extend their systems, applications and directories to partners, suppliers, customers and employees. This explosion in user population makes the task of managing user accounts increasingly complex. It also creates a new need for identity management — the ability to control and monitor individual user access over time. Compounding this situation are the business realities of mergers, acquisitions and divestitures — the numbers of users are increasing and the numbers of system types are expanding. IT directors are forced to manage multiple operating systems, mail systems, network operating systems and home-grown applications distributed across various, often worldwide locations. Individually managing multiple directories is time-consuming, costly and error-prone — especially in organizations where changes frequently occur. Keeping up with the daily maintenance can be a significant task. Ensuring overall security and integrity across the board increases the challenge. To meet these challenges, administrative security systems have been developed to provide user account management across multiple, geographically dispersed security systems and directories. An example of one such system is eTrust™ Admin commercially available from Computer Associates International, Inc. of New York, the assignee of the present application. These systems enable the creation, modification and removal of users across multiple, heterogeneous environments. The single administrative security system allows admimstrators to centrally define and manage security policies across an enterprise by automating the provisioning of user accounts on a variety of IT systems and ERP (Enterprise Resource Planning) applications, for example, using a role-based approach. That is, role-based user provisioning enables the administrators to automatically provide users with a set of userids based on their business functions and ensures consistent user access policies are applied across a wide range of system types and directories. With the advances in centralizing the administration of user accounts, there remains a need for techniques for extracting data from directories and ERP applications to populate the administrative security systems without manually reentering the existing data.

SUMMARY

A system and method for managing user data in a plurality of databases is provided. The system and method extracts user data from a source application, repository or database, transforms the user data into global user data, and sends the global user data to a target application capable of managing the global user data across various environments. According to an aspect of the present invention, a system for integrating data from a source application to a target application is provided comprising an interface module for extracting data from the source application and publishing the data in a first predetermined format; a business transformation logic engine for transforming the formatted data by a plurality of transformation handlers into a second predetermined format usable by the target application; and a configuration interface for defining the data to be transformed from the source application to the target application. The configuration interface formats the data in XML (Extensible Markup Language) format. In a further aspect, the configuration interface defines decision tables based on business rules for combining values associated with data elements of the source application and outputting a value associated with at least one data element in the target application. Additionally, the configuration interface maps data elements from the source application to data elements of the target application. Furthermore, the configuration interface defines an order of execution of the plurality of transformation handlers. In another aspect of the present invention, a method in a computer system for configuring a transformation of data from a source application to a target application comprises the steps of presenting at least one data element to a user from the source application; presenting at least one data element to the user from the target apphcation; and presenting means for associating the at least one data element of the source application to the at least one data element of the target application. The method further comprises the steps of presenting a plurality of XSL (Extensible Stylesheet Language) files for transforming the source application data; and presenting a prompt to the user requesting submission of a sequential order for executing the plurality of XSL files. In a further aspect, the method comprises the steps of presenting a prompt to the user for associating a comparison operator to the at least one data element of the source application; presenting a table for selecting a plurality of data elements of the source application to be compared; and presenting a prompt to the user for associating a result of the comparison to the at least one data element of the target application.

DETAILED DESCRIPTION Preferred embodiments of the present invention will be described hereinbelow with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the invention in unnecessary detail. A system and method for managing user data in a plurality of databases is provided. The system and method extracts user data from a source application, repository or database, transforms the user data into global user data, and sends the global user data to a target application capable of managing the global user data across various environments. FIG. 1 is a block diagram of a system for managing user data in a plurality of databases. Generally, the system 100 includes an interface module 102 for extracting user data from a source application 104 and a business transformation logic (BTL) engine 106 for fransforming the user data into a format usable by a target application 108. The interface module 102 includes a publisher 110 for extracting user data, e.g., employee data, from the source application 104. The publisher 110 publishes an XML message from the extracted user data and sends it to a subscriber 112. The subscriber 112 receives, decodes, and uncompresses the XML message. The subscriber 112 then sends the data to the BTL engine 106 that creates a MessageContext object with XML messages and sends it through a chain of BTL handlers, which will be described in detail below. From the BTL handlers, the object is sent to a workflow engine 114 where a request is created and sent to the target application 108. Depending on the request, the target application 108 creates, modifies, or deletes global users, their accounts, or changes the roles associated with a global user. Additionally, a configuration GUI (graphical user interface) 116 is provided for a user, e.g., an administrator, to define the information to be transformed from the source application 104 to the target application 108. It is to be understood that the present invention may be implemented in various forms of hardware, software, firmware, special purpose processors, or a combination thereof. In one embodiment, the present invention may be implemented in software as an application program tangibly embodied on a program storage device. The application program may be uploaded to, and executed by, a machine comprising any suitable architecture. Preferably, the machine is implemented on a computer platform having hardware such as one or more central processing units (CPU), a random access memory (RAM), a read only memory (ROM) and input/output (I/O) interface(s) such as a keyboard, cursor control device (e.g., a mouse or joystick) and display device. The computer platform also includes an operating system and micro instruction code. The various processes and functions described herein may either be part of the micro instruction code or part of the application program (or a combination thereof) which is executed via the operating system. In addition, various other peripheral devices may be connected to the computer platform such as an additional data storage device and a printing device. Additionally, it is to be appreciated that the system and method may be implemented on several machines coupled together over a network, e.g., a local area network (LAN), a Wide Area Network (WAN), the Internet, etc.. For example, the interface module may be implemented on a first machine while the business transformation logic engine may be implemented on a second machine. It is to be further understood that, because some of the constituent system components and method steps depicted in the accompanying figures may be implemented in software, the actual connections between the system components (or the process steps) may differ depending upon the manner in which the present invention is programmed. Given the teachings of the present invention provided herein, one of ordinary skill in the related art will be able to contemplate these and similar implementations or configurations of the present invention. An embodiment of the present invention will be described below using a

PeopleSoft™ application as the source application and Computer Associates' eTrust™

Admin as the target application with reference to FIGS. 2 and 3, where FIG. 2 is a graphical representation of a PeopleSoft™ eTrust™ Admin Interface (PETAI) module 202 and FIG. 3 is a block diagram of the BTL engine 306. It is to be understood that although the embodiment described below references PeopleSoft' s HRMS (Human Resource

Management System), the principles of the present invention will apply to other source applications and is not limited to that described below. The main purpose of PETAI module 202 is to interface with PeopleSoft™ and to feed the PeopleSoft™ data onto the BTL Engine 306. The feed process will take place using two different mechanisms: Full Data Replication and Incremental Updates. The Full Data Replication process will be used to seed, or initially populate or repopulate, a copy of the entire sub-set of PeopleSoft™ records and fields exported onto eTrust™ Admin. The

Incremental Updates mechanism will keep eTrust™ Admin current, with changes made on the master PeopleSoft™ data. Incremental updates will contain only the records where the data has been modified. The PETAI module 202 will be implemented using PeopleSoft™ Enterprise

Integration technology, specifically using Application Messaging 211, and will be loaded into the PeopleSoft™ application. PeopleSoft™ Application Messaging is based on a "publish-and-subscribe" model that enables a third party external system to integrate with PeopleSoft™ applications via XML/HTTP(S) messages. The PETAI module 202 includes a publisher 210 and a subscriber 212. The publisher mechanism 210 will be deployed onto PeopleSoft™ and will publish and deliver the XML messages to eTrust™ Admin subscriber 212. The PETAI module 202 will comprise two separate publisher mechanisms, one for implementing the Full Data Replication 210-1 and one for the Incremental Updates 210-2. The eTrust™ Admin subscriber mechanism 212 will be deployed onto the PeopleSoft™ Application Messaging Gateway 211 and will capture, transform and pass the XML messages onto the BTL engine 306. The Incremental Updates Publisher mechanism 210-2 will subscribe to internal application messages that synchronize Peoplesoft™ database components when changes are being made to the PeopleSoft™ records and fields. Then, it will build the PeopleSoft™ XML message(s) and populate it (them) with the data, and finally publish it (them) onto the eTrust™ Admin subscriber 212. The Full Data Replication Publisher mechanism 210-1 will query all the defined PeopleSoft™ records and fields to get a full copy of data, then it will build the PeopleSoft™ XML message(s) and populate it (them) with the data, and finally publish it (them) onto the eTrust™ Admin subscriber 212. Many PeopleSoft™ application tables are effective-dated, meaning that historical and future-date rows may be present on the table. eTrust™ Admin does not use effective dating so the PETAI module 202 will need to filter and provide only the current or active information before feeding it onto eTrust™ Admin. This filtering process will take place in the publisher 210 and needs to be implemented for both full data replication and incremental updates publisher mechanisms. The PETAI module 202 will define a sub-set of PeopleSoft™ records and fields that will be published and delivered to the eTrust™ Admin subscriber 212. This definition will be taken from the PeopleSoft™ Message definitions(s) that will carry on the data to eTrust™ Admin. Separate PeopleSoft™ message definitions will be created for the full data replication and incremental updates publishers. The subscriber 212, e.g., a Java subscriber, will be deployed and registered into the PeopleSoft™ Application Messaging Gateway Servlet. It will be in charged of capturing, decoding and uncompressing any XML messages delivered to eTrust™ Admin, and passing them onto the BTL engine 306. Transformations will change the format used in the XML message from a PeopleSoft™ format to an eTrust™ Admin format. The Java subscriber 212 will also integrate with the PeopleSoft™ Application Messaging Config Servlet. The Config servlet will allow the administrator to load/unload the PETAI Java subscriber 212 as well as configuring PeopleSoft™ Nodes to be subscribed from. Integration code will interface with the Config servlet APIs including a HTML graphical user interface for the Java subscriber configuration. To handle large XML messages, a separated thread will process the full data replication messages while the Java subscriber thread will process incremental updates messages. This separate thread is implemented by an EDI (Electronic Data Interchange) engine. Once the subscriber 212 transforms the user data from the source application, the data is passed to the BTL engine 306. The purpose of the BTL engine 306 is to provide a means to transform the input PeopleSoft™ data coming from the PETAI module 202 into

Workflow request(s). This request(s) will lead towards the provisioning, modification or de- provisioning of an eTrust™ Admin Global user and all associated accounts. The transformation will be performed by a series of BTL handlers that will be invoked by the BTL engine 306, as shown in FIG. 3. The invocation process will follow a pre-determined order previously specified in the configuration GUI. Each BTL handler will receive, apply its transformation and pass onto the next handler a MessageContext Object. The MessageContext object is a structure, which will contain the PeopleSoft™ data in an XML format among other parts. The BTL engine 306 will enable the administrator to determine and assign Roles to Global Users based on PeopleSoft™ data; to calculate and assign custom data fields to

Global User attributes, for example, to generate a user id using two or more PeopleSoft™ data fields and some specific business rules; to map data elements within the XML buffer to Global User Attributes; to access custom code and/or third party code to set Global User attributes; etc. The BTL engine 306 will comprise a chain of handlers including a sample template handler 330, XSL files handler 332, business rules handler 334, mapping handler 336, and generic component handler (Dirsync Handler) 338. . The template handler 330 will serve as a starting point for the end user to develop custom BTL handlers for transforming data.

The XSL handler 332 will allow the end user to transform the input XML message based on a chain of XSL (Extensible Stylesheet Language) files. The stylesheet must be provided a separated file containing the XSL Transformation code (no need to re-compile

Java code). To get a hold of the XSL file, this handler will use a parameter in a configuration file containing an ID for the stylesheet 402, the name of the XSL file 404 and an order number to be applied 406, as illustrated in FIG. 4B. For example, a PSCAMA (PeopleSoft™ Common Application Message Attributes) handler may have an entry as follows:

<xsl-entry> <stylesheet-id>pscama</stylesheet-id> <stylesheet-filename>pscama.xsl</stylesheet-filename> <stylesheet-order > 1 </stylesheet-order> </xsl-entry> <xsl-entry> <stylesheet-id>sample</stylesheet-id> <stylesheet-filename>sample.xsl</stylesheet-filename> <stylesheet-order>2</stylesheet-order> </xsl-entry> The PSCAMA XSL program will provide the functionality to filter PSCAMA and data records in the XML message. The filtering code will use an audit action field (AUDIT_ACTN) at the PSCAMA record to filter the data records in the XML message. Logic will be as follows:

The data record will be included in the output if • PSCAMA record not present for a specific data record • PSCAMA record is present and AUDIT_ACTN is set to 'A' or 'C or 'N' or

A sample XSL program will also be provided. It will serve as a starting point for the end user, e.g. administrator, to develop custom XSL programs.

The business rules (BR) handler 334 enables the user to create a set of decision tables that match their specific needs. A decision table is a set of business rules that determine the assignments of special Global User attributes required in the user provisioning process. Special Global User attributes can be roles, profiles, groups, or any other attribute requiring special treatment to determine its value. Decision tables present a sophisticated mechanism to set special attributes without having to write any code. For each special Global User attribute an administrator may want to assign, the administrator will create one decision table. Each decision table needs to specify a set of input parameters to be used in the calculation of the attribute value. A decision table header enables the administer to provide this information. The header's first column is where the output field name is to be placed. Valid output field names are considered any field name on the ETRUST_ADMIN record. The rest of the header columns are where the input parameters are to be placed. Valid input parameters are considered any field on the XML message and must be defined using XPath standard syntax. The decision table rows are where the business rules are defined as illustrated in FIG. 4D. Each row specifies the output value 410, the combination of comparison values 412, and operators for assigning the value 414. The first column on each row is where the output value is placed. The rest of the row columns are where the comparison values and the operators are placed. Nalid comparison values are any real value in the PeopleSoft™ database and valid comparison operators are -' (equal) and '!=' (not equal). The following decision table example assigns the Global User Role attribute (Role- Νame) and uses three input parameters to calculate the value (Country, Department ID, and Company). The sample defines two business rules for assigning two different role values.

The following is the above decision table in XML format: <decision-table-entry> <decision-table-id>roles</decision-table-id> <header> <header-output> <header-field-name>Role-Name</header-field-name> </header-output> <header-input-entry> <header-position>0</header-position> <header-xpath>PERSON/PERSONAL_DATA/COTJNTRY</header-xpath> </header-mput-entry> <header-input-entry> <header-position>l</header-position> <header-xpath>PERSON/JOB/DEPTID< header-xpath> </header-input-entry> <header-input-entry> <header-position>2</header-position> <header-xpath>PERSON/JOB/COMPANY</header-xpath> </header-input-entry> </header> <rows> <row-entry index="0" > <row-output> <row-field-value>NAmerica_HR_GBI_role</row-field-value> </row-output> <row-input-entry> <row-position>0</row-position> <row-comparison-value>USA</row-comparison-value> <row-comparison-operator>=</row-comparison-operator> </iOW-input-entry> <row-input-entry> <row-position>l</row-position> <row-comparison-value>l 0000</row-comparison-value> <row-comparison-operator>=</row-comparison~operator> </row-input-entry> <row-input-entry> <row-position>2</row-position> <row-comparison-value>GBI</row-comparison-value> <row-comparison-operator>=</row-comparison-operator> </row-input-entry> </row-entry> <row-entry index- ' 1 " > <row-output> <row-field-value>International_role</row-fleld-value> </row-output> <row-mput-entry> <row-position>0</row-position> <row-comparison-value>USA</row-comparison-value> <row-comparison-operator>!=</row-comparison-operator> </row-input-entry> </row-entry> </rows> </decision-table-entry>

<decision-table-entry> <decision-table-id>groups</decision-table-id> <header> <header-output> <header-field-name>Group-Name</header-lield-name> </header-output> <header-input-entry> <header-position>0</header-position> <header-xpath>PERSON/PERSONAL_DATA/COUNTRY</header-xpath> </header-input-entry> </header> <rows> <row-entry index="0" > <row-output> <row-field-value>NAmerica_group</row-field-value> </row-output> <row-input-entry> <row-position>0</row-position> <row-comparison-value>USA</row-comparison-value> <row-comparison-operator>=</row-comparison-operator> </row-input-entry> </row-entry> <row-entry index=" 1 " > <row-output> <row-field-value>International_group</row-field-value> </row-output> <row-input-entry> <row-position>0</row-position> <row-comparison-value>USA</row-comparison-value> <row-comparison-operator>!=</row-comparison-operator> </row-input-entry> </row-entry> </rows> </decision-table-entry>

The business rules handler 334 then sends the message to the mapping handler 336. The BTL mapping handler 336 associates one PeopleSoft™ data field or a custom record field 420 to a Global User attribute 422 of the eTrust™ Admin application as shown in FIG. 4C. The mapping supports the association of any element and any non-element within the XML message to a Global User Attribute using XPath standard syntax. The mapping of attributes will be defined by XML data stored in the configuration file. The end user can customize the XML data to fit their specific needs using the configuration GUI as illustrated in FIG. 4C. The configuration file will use XPath standard syntax to define the mappings having the root element as the context for all definitions. The following XML data represents a sample PeopleSoft™ XML message:

<MsgData> <Transaction> <PERSONAL_DATA class="R"> <EMPLID>C1000K/EMPLID> <NAME>Stankowski,Richard</NAME> <LASTJSrAME>Starjkowski</LASTJSrAME> <FlTlSTJ^AME>Richard</FIRST_NAME> <MIDDLE_NAMEx/MIDDLE_NAME> <COUNTRY>USA</COUNTRY> <ADDRESS1>11308 Wildflower Lane</ADDRESS1> <ADDRESS2></ADDRESS2> <ADDRESS3></ADDRESS3> <ADDRESS4x/ADDRESS4> <CITY>Grass Valley</CITY> <COUNTYx/COUNTY> <STATE>CA</STATE> <POSTAL>97077</POSTAL> </PERSONAL_DATA> <JOB_ETA_VW class="R"> <EMPLID>C10001</EMPLID> <DEPTID>13000</DEPTID> <DESCR>Finance</DESCR> <JOBCODE>KU067</JOBCODE> <JOBCODE_DESCR>Sr Accounts Payable Clerk</JOBCODE_DESCR> <LOCATION>KUDE00</LOCATION> <LOCATION_DESCR>Delaware Operations</LOCATION_DESCR> <EMPL_STATUS>T</EMPL_STATUS> <COMPANY>GBI</COMPANY> <BUSINESS_TJNIT>GBIBU</BUS1NESS_UNIT> <BUSINESS_TITLEx/BUSINESS_TITLE> <SUPERVISOR_IDx/SUPERVISOR_ID> </JOB_ETA_VW> </Transaction> </MsgData>

For example, mapping definitions for "EMPLID" and "DEPTID" elements will be represented using XPath standard syntax as:

<eta21 -attribute-mapping> <custom-element-xpath>PERSONAL_DATA/EMPLID</custom-element-xpath> <attribute-name>eTUserid</attribute-name> <attribute-mod-flag>over rite</attribute-mod-flag> </eta21 -attribute-mapping> <eta21 -attribute-mapping> <custom-element-xpath>PERSONAL_DATA/EMPLID</custom-element-xpath> <attribute-name>eTGlobalUserName</attribute-name> <attribute-mod-flag>ovenvrite</attribute-mod-flag> </eta21 -attribute-mapping> <eta21 -attribute-mapping> <custom-element-xpath>JOB_ETA_VW/DEPTID</custom-element-xpath> <attribute-name>eTDeρartment</attribute-name> <attribute-mod-flag>overwrite</attribute-mod-flag> </eta21 -attribute-mapping> The generic component handler 338 will be the end point in the BTL engine chain and ultimately will transform the PeopleSoft™ data into Workflow requests. Among other functions, the configuration GUI 116 will be employed to configure the various BTL handlers. The purpose of the configuration GUI 116 is to provide a means for a system administrator to easily define the information that is needed to transform a PeopleSoft™ User Entry into an eTrust™ Admin Global User Entry. This information will include the resulting eTrust™ Admin Global User attributes and the means that is used to produce them. The BTL configuration GUI 116 will be comprised of the following interfaces as illustrated in the exemplary screenshots of FIGS . 4 A-E :

• Node Selection (FIG. 4A): This interface will allow the end user to select a node of the source application to be configured.

• BTL Handlers Registration (FIG. 4B): This interface will allow the end user to register BTL handlers on the BTL engine and define their invocation order. It will also allow the end user to add, remove or modify the loading order of XSL files.

• Attribute Mapping Interface (FIG. 4C): This interface will allow the end user to define the mapping parameters used by the BTL Mapping Handler.

• Decision Tables Interface (FIG. 4D): This interface will allow the end user to create and add decision tables to be executed by the BTL Business Rules Handler. • General Configuration (FIG. 4E): This interface will allow the end user to set all remaining configuration parameters.

The configuration GUI 116 will additionally enable the administrator to set any necessary configuration parameters. These configuration parameters will be held in the XML configuration file mentioned above. The subscriber, BTL Engine and BTL handlers access and load settings from the configuration file in order to operate. For example, the subscriber reads supported message definitions, message node name, full data replication output folder, etc.; the BTL Engine reads the registered BTL handlers and loading order, etc.; the BTL Business Rules handler reads decision tables, etc.. Below is an exemplary list of parameters included in the configuration file:

Additionally, below is an exemplary list of decision table parameters used in configuring the business rules handlers:

It is worth noting that to define the mappings and the BR decision tables meta-data will be required. This meta-data will be needed for both eTrust™ Admin and PeopleSoft™. In the case of PeopleSoft™, it will consist of the attributes that can be used as parameters to the Decision Table Definitions. In the case of eTrust™ Admin, this data will consist of a list of all supported Global User attributes. There will be two ways that the PeopleSoft™ data can be obtained from the BTL Configuration GUI. The first is by using a PeopleSoft™ Extract. From an existing extract, the BTL configuration GUI will be able to obtain the required meta-data. At any time, the system administrator will be able to add to and modify this meta-data. In the case of eTrust™ Admin meta-data, a listing of the attributes that exist will be readily available from the configuration GUI. In the BTL Configuration GUI, the eTrust™ Admin meta-data may be modified as well. With reference to FIGS. 5 and 6, a method for managing user data in a plurality of databases will be described illustrating the data flow where the source application is a PeopleSoft™ application and the target application is eTrust™ Admin. The PETAI module 602 will interface with PeopleSoft™ system 604 (step 502) and will feed PeopleSoft™ data onto the BTL engine 606 through its Java Subscriber 612 (step 504). The BTL engine 606 will generate a MessageContext object containing the PeopleSoft™ data and it will pass it on to the first BTL handler defined in the configuration file that in this case is the sample template handler 630 (step 506). The template handler

630 will process and transform the MessageContext object and it will pass it on to next handler in the chain. The XSL files handler 632 receives the MessageContext and applies a chain of XSL Transformations, e.g., PSCAMA.XSL and sample.XSL (step 508). The business rules handler 634 receives the MessageContext object and transforms it executing any decision tables defined in the configuration file (step 510), via the configuration GUI 616. Then, it will pass it on to the mapping handler 636. The mapping handler 636 receives the MessageContext object and transforms it assigning PeopleSoft™ data fields and custom fields to Global User attributes based on the mapping information in the configuration file (step 512). Then, it will pass it on to the generic component handler 638. The generic component handler or end point handler (Dirsync Handler) will ultimately generate eTrust™ Admin Workflow requests (step 514), via the workflow engine 614. This request(s) will lead towards the provisioning, modification or de-provisioning of Global user and all associated accounts in the eTrust™ Admin application 608. The system and method according to embodiments of the present invention provides organizations the ability to capture changes to a source application, e.g., a PeopleSoft™ application, in real time. The system and method transforms the data into "intelligible" user provisioning requests based on business rules associated with specific values in the source application data. The system and method then submits these requests via a workflow engine to a user provisioning engine, e.g., a target application, which ultimately sends (create, delete, or modify) requests to managed security systems. In summary, embodiments of the present invention automate the user provisioning process from a source application to the heterogeneous security systems making up the organizations IT infrastructure. While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
