Data (See data directory for examples)

Object A

• value (float)
• color (str)

Object B

• function (str)
• value (float)

Object C

• value (list of float)

Tasks

1. Create a database DB to store objects A, B and C each in a separate table
2. Implement a function that takes A and B and return C, where B.function applies to A.value and B.value and the result is stored in C.value with an index that depends on A.color according to the map:

COLOR 2 INDEX MAP

• red -> 0
• green -> 1
• blue -> 2

Example 1

INPUT 1

• A.value = 3
• A.color = green
• B.function = sum
• B.value = 3

OUTPUT 1

• C.value = [ 0, 6, 0 ]

Example 2

INPUT 2

• A.value = 2
• A.color = red
• B.function = pow
• B.value = 2

OUTPUT 2

• C.value = [ 4, 0, 0 ]

3. Implement a function similar to function-2 but with INPUT from DB and OUTPUT to DB
4. Add REST endpoints to function-2 and function-3
5. Wrap it all up in a Docker container (i.e. write Dockerfile and docker-compose.yaml)
