Whenever you define interfaces, you will need to implement them. In most cases, you will create an abstract base class that provides a certain amount of default functionality. The abstract base class serves the same purpose as outlined in the previous chapter: to provide a certain amount of basic functionality. In the case of the tax engine, we need to implement the ITaxEngine interface and provide default implementations for some methods, and for some abstract methods that the derived class needs to implement in other methods. The following is the complete base class implementation. public abstract class BaseTaxEngine : ITaxEngine{ protected double _calculatedTaxable; public BaseTaxEngine() { } public virtual double CalculateTaxToPay(ITaxAccount account) { _calculatedTaxable = 0.0; foreach (ITaxIncome income in account.Income) { if (income != null) { _calculatedTaxable += income.TaxableAmount; } } foreach( ITaxDeduction deduction in account.Deductions) { if (deduction != null) { _calculatedTaxable -= deduction.Amount; } } return account.GetTaxRate( _calculatedTaxable) * _calculatedTaxable; } public virtual ITaxDeduction CreateDeduction(double amount) { return new TaxDeduction(amount); }

Figure 5-4. Implementing a Many-to-Many relationship using a junction table There s no definitive naming convention to use for the junction table. Most of the time it s okay to just join the names of the two linked tables in this case, our junction table will be named ProductCategory.

public virtual ITaxIncome CreateIncome(double amount) { return new TaxIncome(amount, 1.0); } public abstract ITaxAccount CreateTaxAccount(); } The base class must implement all interface methods, regardless of whether or not the method has an implementation. The CalculateTaxToPay(), CreateDeduction(), and CreateIncome() methods have implementations. The CreateTaxAccount() method does not have an implementation and is declared as abstract. The methods with implementations have a virtual keyword associated with them, indicating any class derived from BaseTaxEngine can override the functionality if they don t like the default functionality. In the implementation of CalculateTaxToPay(), the income (account.Income) is added together and deductions (account.Deductions) are subtracted from the income. The resulting total is used as a query amount (account.GetTaxRate()) to retrieve the actual tax rate used to calculate against the payable tax.

Relationships between tables are physically enforced in the database using FOREIGN KEY constraints, or simply foreign keys. You learned in the previous chapter about the PRIMARY KEY and UNIQUE constraints. We covered them there because they apply to the table as an individual entity. Foreign keys, on the other hand, always occur between two tables: the table in which the foreign key is defined (the referencing table) and the table the foreign key references (the referenced table).

Note The implementation of CalculateTaxToPay() is a shared functionality, which implies that there cannot be any code specific to a derived type. All of the calculations and data manipulations are executed against an interface, making it possible to generalize operations. Whenever you implement base class methods or shared pieces of code, you should try to keep the source code derived class agnostic.

Tip Actually, the referencing table and the referenced table can be one and the same. You won t see this too often in practice, but it s not unusual, either. For example, you can have a table with employees, where each employee references the employee that is their boss (in this case, the big boss would probably reference itself).

To correct this problem, change the contents of the Cell Reference box or the Constraint box so that the number of cells in the Cell Reference box equals the number of cells referenced in the Constraint box..
