Languages:                   C#.Net, Java (jdk 1.6), PL/SQL

 

Description:                  This is an inventory tracking solution on .Net platform & Java (following event-driven architecture) using passive RFID technology & Oracle Sensor Edge Server (Oracle SES) for real-time location determination of warehouse stuffs arranged in shelves.

 

Responsibilities:            API & Adapter development in Java for RFID devices that implements the Physical Proxy component of the Oracle Sensor Edge Server.

 

Filter & Dispatcher development in Java (These are components of the Oracle SES). The Filter hosts the redundancy checks and the filtering logics. The Dispatcher stages the RFID data from the devices to the database. These are the core components that constitute the Oracle SES.

 

Window based Real Time Monitoring application development including GUI in .Net using C# over TCP/IP that displays the current status & location of the warehouse stuffs within & outside the RFID equipped Smart Shelves with visual alarms & email notifications.

 

PL/SQL Functions, Stored Procedures & Queries used by the data access layer of the application for data archival, retrieval & lookups.

 

PL/SQL Packages & Advanced Data Types (ADTs) that runs the entire business logic of the application and logs the processed data for reporting & auditing.

 

Highlights:                     The business logic of the application runs at the database level rather than in a middle tier.
