Assignments Group B (Any Six Assignments, All assignments to be covered in a Batch)
1 Design at least 10 SQL queries for suitable database application using SQL DML statements:
Insert, Select, Update, Delete Clauses using distinct, count, aggregation on Client-Data
sever(three tier)
2 Implement database with suitable example using MongoDB and implement all basic
operations and administration commands using two tier architecture.
3 Use MongoDB to process semi structured and unstructured data collections such as Rfid,
images, blogs use python/Java MongoDB interface.
