In this section I ll introduce the different tools available for you to protect the quality of your data Understanding the tools at your disposal for protecting data quality is the second most important thing to know and know well (the third being how to write set-based queries, and the first being normalization) This chapter is about automatic data protection, meaning tools that can be used to seamlessly protect the integrity of the data without any further coding effort or user action to make sure that they work, and no method of overriding the protection without cheating (you can disable some protections, and you can get around them using bulk copy methods) You can also take manual steps to protect your data; they generally require the client to adhere to a given API to work This could include stored procedures, client code, defaults, and so forth.

Ideally, you ll use the GUID property to uniquely identify the contact you re planning to nail, as this helps you avoid getting a different contact with a similar name But unless you can examine the Entourage installation on which your script will run, it s not likely that you ll know the GUID for a particular contact (And if you can examine the Entourage installation, you will probably find it easier to take out the victim manually rather than using AppleScript)

I won t discuss manual protection in this chapter, but the point of using manual data protection techniques is that they enforce rules that can be overridden or applied situationally, or that are frequently changed These rules are generally apt to change, so you wouldn t be able to easily write a query to find data that didn't meet the rules over a long period of time.

We ll discuss the following types of protection that allow you to design integrity into the base structure: Data types Defining the storage of values of the proper base type and size NULL specifications Making sure that only columns where you might have a NULL value are defined to allow NULLs Uniqueness constraints Preventing duplicate values for a column or set of columns Filtered unique indexes Preventing duplicate values for a column or set of columns for a subset of rows in the table Foreign key constraints Making sure every foreign key value has a corresponding primary key value in the related table.

Figure 16-4

Check constraints Checking that values in the row meet the minimum standards Triggers The catch-all of data protection, which allows you to execute a batch of code for any DML operation to validate data and even introduce side effects to the DML operation that happen without the knowledge of the client As you ll see in the following subsections, this list is loosely ordered from the most desirable to the least desirable, particularly where there s overlap.

You will probably need to reassure Entourage that your scripts that try to access the address book are genuine, honest, and friendly

The most fundamental thing you can do to ensure the quality of your data is to choose a reasonable container for the value being stored. Want to store an integer value Use an integer type. Want to store an image Use a varbinary(max). Could you use a varchar(50) or varchar(max) to store every value In almost every situation, you sure could. You could also stick your tongue in a lamp socket, but I guarantee you it s a bad idea unless you want to say hi to your cat that your mother told you was sent off to live on the farm. Way too often, I see designs where every column is nvarchar(50), unless they want to store something larger; then it s an nvarchar(max). Storagewise, unless you expect that some values will have special characters, using a Unicode-enabled type just costs you space, and even worse is absolutely horrible for data integrity. It s perfectly possible to do this and get by, as all values can be represented as a textual value in a T-SQL DML statement. So why bother First, consider performance. As an example, consider storing a GUID value in a varchar column. Using the uniqueidentifier data type, you can store the 36-character value in 16 bytes. Put it in a varchar column and you ll need 36 bytes, or 72 if the column is nvarchar. The second, more important problem is data integrity. A uniqueidentifier column requires a properly formatted GUID to be stored, whereas a varchar column is happy to take Your data integrity blows as a value.

DECLARE @x xml; SET @x = N''; SELECT @x.query('"ABC" lt "XYZ"');

The Number One reason for a script to access your address book is to blitz your contacts with spam offering mail-order brides and pills that will help the recipients retain them, so Entourage displays the alert shown in Figure 16-4 The user must click the OK button to let the script continue
