2002 -  2003
Senior Software Designer

Worked in AT and T as consultant of comrise, worked on Dbor project. This is an EAI project that aims to provide a uniform view to client for different products and different backend.
Built the n-tier framework to aggregate different backend to each product, used Strategy pattern for different backend implementation.
Built the template for parallel query to different backend using Message Driven Bean to send message and temporary query to get response message which improved the performance.
Designed and implemented the DborToolSet and several different tools as Free Circuit tool, Dulicate Uso Number tool, Service Disruption Alert, from front end to back end. Each tool involves several different backend. Used Intercepting Filter for configurable security of this web application. Designed input validation library using javascript.
Designed Web Services for Nodal project, used SOAP and WSDL.
Designed applications using Struts and tiles.
Evaluated and proposed WLI as the tool of next Dbor project.
Designed and led DBOR/E-MAP project development. For the first phase, this project is related to 2 backends URSP and EFMS, they are both relational databases. EFMS is a tracking system and we need real time data ; USRP is an ordering system and we decided to load data from there to our local database daily to improve real time query. The project consists of 2 parts : batch load part and real time part.

a. Batch load part load data from USRP and use an external socked based application called map info tool to populate some geo longitude and geo attitude data. 3 stored procedures in USRP and map info tool are used to populate 4 tables in our local database. This batch load part consists of several components : Reader, Mapper, Transformer, Writer. Reader load data from USRP stored procedure, Mapper maps the result from Reader to format of our local database, Transformer performs some transformations defined in the requirement and Writer saves the transformed result to our local database. Mapper and Writer are generic, they is used in other projects only with configuration file change ; Implementation of Reader and Transformer are specific to this project but other projects can write classes that implement same interface.
b. Real time part queries the 4 tables and EFMS and aggregates them and return aggregated result to real time users. This part consists of several layers : access, aggregation and client. Access layer queries the 4 tables in our local database and EFMS. SQL statement for queries to our local database are dynamic, ie, it can vary depending on value of certain input ; query to EFMS involved several tables and lots of business logic. Aggregation layer first goes to our local table to get uso number and then use the uso number to query EFMS and aggregate result from our local database and result from EFMS. Client layer further aggregates result from aggregation layer and provides a client specific view to E-MAP.

I prepared UML diagrams for both part : use case diagrams, activity diagrams for each use case, domain object diagrams, component diagrams, class diagrams and sequence diagrams .I prepared ant build for compilation and ejb, war creation using doclet.
