A merchant shipping company wishes to use a computer database to help with its operations. There are three distinct areas in which such assistance is desired.
First, it is required that details of the company fleet be recorded. The fleet comprises a number of types of ship: cargo vessels have a deadweight (cargo capacity), class of cargo carried (e.g. dry, container, grain) and number of onboard loading derricks; oil tankers also have a deadweight, and a class of petroleum for which they are equipped; and passenger vessels have a maximum passenger capacity for each of “first” and “tourist” classes, and a number of staterooms. All ships have a crew, which comprises, a master, a number of officers and seamen. They have length, beam, draught and displacement, and burn particular types of fuel. They also have a maximum speed and endurance. Each ship has a home port, which may or may not be the same as its port of registration.
Secondly, the officers and crew have to be paid! Their salary depends on their qualifications and current appointment – to which ship and in what capacity. There is also a “bounty” payment made in respect of each trip made, which depends on the length of the trip and on the individual’s length of service with the company. In addition, ship’s officers who are sailing in less than their customary capacity (e.g. a master sailing as a first mate) receive an extra payment.
Finally, the company is required by its insurers to maintain a record of the position of each vessel; its port and date of departure, destination and estimated date of arrival; number of officers, total number on board, and total value of cargo carried, if any. Ships currently in dock for repairs must also be included in this catalogue.

Design the database for a programming support environment. In this environment programmers produce programs, which are written in given programming languages. Each program is written by a given programmer, can call other programs, and can be used by given users. Users are recognized by their log-in names. Programmers are recognized by their log-in name and by their code. Programs have compound names that include the program’s name, the extension and the programmer’s code. Programs have a version number, a date and a short description; some programs interact with DBMSs. Each DBMS maintains stored data in the form of relations, with several attributes and one primary key. Each database is defined by a database administrator, who is a programmer specialized in data management. State clearly any assumptions you make.

Function Name: erosion
Inputs (3): - (double) An MxN array representing the heights of the topsoil in a particular area
- (double) An MxN array representing the heights of the bedrock in the same area underneath the topsoil
- (double) An erosion factor
Outputs (1): - (double) An MxN array representing the new heights of the topsoil with the applied erosion factor
Function Description:
Write a function that takes in arrays representing the heights of topsoil and bedrock of the same area and an erosion factor, and outputs the new heights of topsoil with the applied erosion factor. Assume that the topography is uniformly eroded by subtracting the erosion factor from each element of the topsoil array. Since topsoil erodes much more easily than bedrock, the erosion factor can completely erode the topsoil but should not affect the bedrock. For example, for a particular spot that has a topsoil of 34, bedrock of 0, and erosion factor of 26, the new height should be 10 and not 8.
