Using Chen Model with the (min, max) notation, provide the appropriate cardinality using the above business rules for number 1 Place the following eras of IT infrastructure evolution in order, from earliest to most recent: (1) Cloud Computing Era (2) Client/Sever, (3) Enterprise Era, (4) Personal Computer, and (5) Mainframe and Minicomputer. 1) 4, 5, 3, 2, 1 2) 5, 4, 2, 3, 1 3) 4, 5, 2, 3, 1 4) 5, 4, 2, 1, 3 The four steps are problem identification, solution design, choice of a solution, and implementation. In the problem identification step, relevant people in an organization must agree that a problem exists, about what the problem is and what its causes are, and what can be done about the problem given the organization's resources. In the solution design step, as many possible solutions should be determined. In the choice step, you choose the best solution from the list of options determined in the previous step. It is important to match a choice to existing resources, skills, and feasibility. In the last step, implementation, the solution is put in place. In information systems solutions, this may include purchasing hardware or software and testing it. Implementation also includes employee training, change management, and using a method to measure the outcome. The three dimensions to business problems are: Recommended textbook solutions
