Summary
Without tables in a database, you cannot store data. Therefore, tables become the base of everything you do with SQL Server. However, you need to do more than simply create a bunch of tables and start throwing data into them. Without a structure to the data, your applications will be difficult to write, and performing comparisons among the data will become difficult, if not impossible. The initial structure for data is provided by a set of data types that define the type as well as basic limitations on the data. The broad categories of data types are as follows:
Exact numeric
Stores precise numbers either with or without decimals.
Approximate numeric Stores numeric values with or without decimals.
Stores numeric values with decimal places. Used specifically for currency values with up to four decimal places.
Monetary Date and time Stores date and time information and enables special chro-
nological enforcement, such as rejecting a value of February 30.
Character Binary
Stores character-based values of varying lengths.
Stores data in a strict binary (0 and 1) representation.
Special purpose
Complex data types for data that requires specialized handling, such as XML documents or GUIDs.
You can further enforce business rules by using constraints. The set of SQL Server constraints that you can use are the following:
Check
Enforces boundary values on a column and can also force specific formatting requirements for data.
3 Review
Rule Functionally equivalent to check constraints, but can be reused for
more than one column.
Default Provides a value to a column when one is not specified by the user. Unique Ensures that duplicate values cannot be stored in a column or
group of columns.
Primary key Foreign key
Provides a way to uniquely identify each row in a table. Forces all values entered into a column to exist in another
table.
You can use Transact-SQL UDTs to create a consistent definition for columns based on a native SQL Server data type. When the native SQL Server data types are not sufficient, you can define your own data types with custom processing by using the CLR integration.

Case Scenario: Designing a Database
In the following case scenario, you will apply what you ve learned in this chapter. You can find answers to these questions in the Answers section at the end of this book. Contoso Limited, a health care company located in Bothell, WA, manages patient claims data. To support the business, you need to create a database to store the wide variety of data related to patient claims. You need to create structures for basic patient data, such as name, address, date of birth, and Social Security number. The database also needs to store the companies that Contoso works with, including the company name, address, and people to contact. Each patient claim must be associated with a company in the database. And the database needs to associate a list of doctors with a claim and also store various supporting documents.
3 Review
All pieces of data need to be uniquely identified within the tables. Referential integrity is crucial to the successful operation of the database application. How would you define the table structures to meet the needs of the patient claims database
