Java Spring Boot application to download data from website

I run an investment consultancy. I want to build a software which will download market data from NSE and BSE website and save it in MYSQL Database. I need a java spring project which will download NSE and BSE daily market data and will store in Mysql tables. The links to download are as follows: NOTE: the are link for only single day e.g. 07 OCT 2019. NSE_EQ = [login to view URL] NSE_DERIVATIVE = [login to view URL] NSE_CURRENCY = [login to view URL] NCDEX_COMMODITY = [login to view URL] BSE_EQ = [login to view URL] Task to be done: 1. Design the MySQL DB shcema 2. Write an optimized REST API code to download the above URLs. The code MUST take date range. The downloaded data MUST be persisted in a directory. The URL which provides ".zip" file needs to be UnZipped in another directory. This directory also must be persisted. 2. Write and optimized code to parse the downloaded/UnZipped CSV files and save it to MySQL DB. 3. Write optimized REST API code to fecth data from MySQL DB by providing Market_Segment = NSE_EQ or NSE_DERIVATIVE or NSE_CURRENCY or NCDEX_COMMODITY or BSE_EQ SCRIPT_NAME = RELIANCE or SBIN or USDINR or ..... DATE_RANGE = FROM = 01SEP2019 , TO = 05OCT2019 4. ALL REST API must have some username and password to access 5. ALL API must have cron/quartz scheduler for daily data download 6. The code MUST contain JUNIT Testcses 7. Stepwise delivery expected 8. Findal delivery should contain the following: 1. Software design block diagram 2. Database schema diagram 3. Complete working code with test cases in JAVA, Spring Boot 4. MySQL DB schema in ".sql" file format 5. POSTMAN project to test the REST APIs NOTE: Stepwise payment may be released if working code is delivered. I am always avilable for a discussion and will guide if you are blocked on some point.
