Prepare the relational tables to represent the following situation, which is described by means of text and an entity relationship diagram. Note: do not attempt to modify the erd. Your task is to state the relational tables which fit the given erd. The nsw government has agreed to set up an organisation to monitor the fishing industry in this state. The concern is that over-fishing might lead to the eventual extinction of some species and great problems for those people who depend on seafood for their survival. The organisation wants a computer based information system to store the data necessary to monitor the situation. All commercial fisherpersons within the state must have a licence to fish which is granted each year by the organization. Records of all licences issued over the last 5 year’s must be maintained by the system. A register of all major species, identified by the government species code, is to be kept and is to be regularly updated with the population surveys of each species which will be carried out by the organisation's scientists. The scientists will work out a "minimum population" figure and a "total catch" figure, for each calendar year, for each species. Each licenced commercial fisherperson must apply to the organisation annually for quotas which specifies the amount of each species of seafood that the fisherperson can catch in a particular year. A catch report must be made by each commercial fisherperson listing the tonnage of each species caught on each fishing expedition. The fisherperson also provides a brief weather description for each expedition and the boat name. The organisation has inspectors who do random audits to ensure that the catch reports are accurate. These reports are to be stored so that the quotas can be checked to ensure that fisherpersons are not over-fishing. The system will produce regular reports of trends in species populations and exception reports where the population seems to be falling rapidly, or it is approaching the "minimum population" levels, or where the population surveys do not match the catch reports. One type of report is shown below for mr john snapper. (note that there are several other types of reports.) mr john snapper lic# 7373 18 mermaid st geelong (03)224556 species no.
