Project 6: Moderation

Description Moderation is a desktop application which uses a messaging service, known as Genava to get the posts from a Jive (social media framework) instance through a plugin. This application is developed for Apple client. The moderator is a role-based user, which filters out the abusive reports posted by any Jive user.The filtering is done on the basis of some keywords.This is multi layer architecture but using MVC pattern. Cocoa client is used as view. The server part is written in Java and hence Thrift call is used for server client communication.JPA with eclipse-link is used for backend support.

Team size 10Duration August 2012-Jan 2014Contribution Developed Java codes for models, DAOs, Services and

Actions.Used Oracle database to maintain the records and used JPA to interact with DB.Created Rest Service using Jersey-JaxRS to support apple delete. Admin can call this service to delete a user and also update the associated records.

Project 5: Desktop POS

Description Justeat.in is an e-commerce company. It provides facility for on-line food ordering through it's website or through phone calls. To handle the phone calls, it has a call center set up. But, when the order comes through web site, there are three solution, GPS device, call center and Desktop POS(DTP),which handle the order.GPS device runs on the sim card and is installed in the restaurant to fetch the response from a url generated by Justeat APIs.If the restaurant has Internet connection and a PC, then the best solution is the Desktop Pos(DTP). It provides a GUI, developed on Swing. The application runs a timer and send http request to the Justeat server after a fixed interval, if there is any Json response from the server for a particular order, it fetches the response parse it display to the screen. Along with that, it uses multi-threads to notify the restaurant by a toaster pop-up and a music. These all run in separate threads. The application maintains all the essential records in database. We have used MySql database and Hibernate to store all the records. When the restaurant accept or reject the order, it prints the details of the order and sends a http request to verify the status on the server whether the order has been successfully placed or not.The DTP also maintains the menu management and order management system. The best feature is it's auto updater. Whenever a new version of the application is released, it gets auto updated.

Team size 4Duration January’2012-July 2012Contribution Developed Java codes for models, DAOs, Services and

Actions Created GUI to display the order details using html templates.Used Multi-threading to create toaster pop-up, play music and print the order.Used MySql database to maintain the records and used Hibernate to interact with DB.

Project 4: Nucleus Project

Description The application is build to implement dynamic generating crime status report for the New York police department (NYPD) with lots of admin and user capabilities. In the application there are number of users having different privileges to create affidavit, grant it, approve it and after search to submit return. All the users involved in the application have to digitally sign the document for that user will be provided a third party certificate and a key and based on that a digitally signed PDF will be generated. Admin can provide privileges on the Role as well as user level. In the application user belongs to multiple groups and a group contains a number of roles so here a user can have a number of distinct roles. Permissions can be given on role level or user level. Application also extends to other modules like case management modules, person management, confidential sources management, Incident Management, Operation and many more. Crime status reports are generated on year to date, month to date and week to date basis. It uses the data from database to report the status in numeric forms with percentage count and also generates report in line chart and bar chart format. The application is further extended to Crime Reduction Initiative module, where reports in form of line chart has to be generated on year, month and day basis after taking the initiatives with status of the initiatives as in progress, complete or cancelled.The application has been extended to run on weblogic10.3 server and oracle 11g database. Also the application has been integrated with OBIEE to generate reports, graphs and chart using OBIEE and BI Publisher webservices.

Project 3: Mediation and Reporting System

Description Mediation & Reporting System is a step forward from original passive monitoring systems to a much more active performance-management system. This provides intelligence to the Billing System and empowers the users to make better operational and strategic decisions. The system collects raw CDRs and HLR logs from different NE’s like IN, VoMS in XML and JSON format. FTP and FTAM interfaces are supported for transferring of data from the NE to the MRE. The raw CDRs are processed using XML and JSON parses and all the required data are stored in the database. Reports are generated on hourly, daily, weekly and monthly basis, conversion of the CDRs and generation of Report based on the same. The framework supports conversion of different CDR formats and generation of reports as JSP and JASPER Reports.
