First question solution can be found in attachment.
Code:1) Write down any custom built C++ Class which you think is not cohesive (or low cohesive). Public I Enumerable<Employee> GetEmployeesFromDb_LowCohesion() { // instantiate the links using(SqlConnection connection = newSqlConnection(ConfigurationManager.ConnectionStrings[CONNECTION_STRING_KEY].ConnectionString)) using(SqlCommand command = new SqlCommand("spGetEmployee", connection)) // instantiate the command { command.CommandType = CommandType.StoredProcedure; // try to open the links try { connection.Open(); } catch (InvalidOperationException ex) { // log exemption throw; } catch (SqlException ex) { // log exemption throw; } catch (Exception ex) { // log exception throw; } // perform the reader & read the results using(SqlDataReader reader = command.ExecuteReader()) { Int32 m_NameOrdinal, m_DeptOrdinal; // obtain the ordinals try { m_NameOrdinal = reader.GetOrdinal(NAME); m_DeptOrdinal = reader.GetOrdinal(DEPARTMENT); } catch(System.IndexOutOfRangeException ex) { // log exemption throw; } Collection<Employee> result = new Collection<Employee>(); // interpret the results while(reader.Read()) { try { Employee emp = new Employee(); emp.Name = reader.IsDBNull(m_NameOrdinal) ? String.Empty: reader.GetString (m_NameOrdinal); emp.Department = reader.IsDBNull (m_NameOrdinal) ? String.Empty : reader.GetString(m_DeptOrdinal); result.Add(emp); } catch (IndexOutOfRangeException ex) { // Log the exemption throw; // rethrow or handle gracefully here } catch (Exception ex) { // Log the universal exemption throw; // rethrow or handle gracefully here } } return result; } } }
