What is the minimum number of database requests you need to write for an inventory update for both PRODUCT and PART? Using proper SQL syntax for an Oracle database, write each request below.

In anticipation of a change to the database, you are asked to provide a list of all products that have 'Man-Made' or 'Man Made' in the the composition text. (HInt: It is easiest to use LIKE in this instance.)  In addition, you are requested to replace either 'Man-Made' or 'Man Made' with the word 'Synthetic'. Only include ProductIDs between 1050 and 1060.  Show the following in your answer: ProductID, ProductName, Composition, and the modified composition field as 'NewComposition'.   (HINT:  This problem is a little tricky because you need to replace both 'Man-Made' and 'Man Made'.  The way to do this is to use a replace within a replace.)
