This project involves tracking network fault complaints from the customers. And also to examine information flows formally and informally within a customer complaint handling process, and to identify possible improvement areas to strengthen the network signal.
Data in the MYSQL database is transformed loaded into HDFS. Later this data is analysed using Hive that exposes data in HDFS in a Distributed Query enabled platform. Sqoop is used to extract data from internal

Unique identification project was initially conceived as an initiative that would provide Identification for each resident across the country and would be used primarily as the basis for Efficient delivery of welfare services.

This project involves tracking network fault complaints from the customers. And also to examine information flows formally and informally within a customer complaint handling process, and to identify possible improvement areas to strengthen the network signal. Data in the MYSQL database is transformed loaded into HDFS. Later this data is analyzed using Hive that exposes data in HDFS in a Distributed Query enabled platform. Sqoop is used to extract data from internal structured data stores and load into HDFS. Data volumes range in Gigabytes, which makes it challenging for regular analytics platform

Exigent has a software product roadmap to build a Contract Management product that can be implemented both on-cloud and on-premise for Exigents customers.
