SQL Server is an enterprise relational database management system from Microsoft. We use SQL Server as the database server for data storage and data retrieval to and from Microsoft Access as well as other software applications, like ASP.NET and Azure.

Alison Balter at MS Access Solutions developed the application that helps us to properly service all of our members. This program handles billing, payments, tracking of jobs worked, available list, and other important data about our members. The system automates many tasks that were previously performed manually, allowing our employees to more cost-effectively use their time. This client/server system is used by employees in our Tuscon AZ and New York offices. MS Access Solutions and their staff worked with us to develop the necessary specifications and design documents, and then programmed, tested, and implemented the application throughout our organization.

Establishing Referential Integrity As you can see, establishing a relationship is quite easy. Establishing the right kind of relationship is a little more difficult. When you attempt to establish a relationship between two tables, Access makes some decisions based on a few predefined factors: 1. Access establishes a one-to-many relationship if one of the related fields is a primary key or has a unique index. 2. Access establishes a one-to-one relationship if both the related fields are primary keys or have unique indexes. 3. Access creates an indeterminate relationship if neither of the related fields is a primary key and neither has a unique index. You cannot establish referential integrity in this case.
As covered earlier in the chapter, referential integrity consists of a series of rules that the Access Database Engine applies to ensure that it properly maintains the relationships between tables. At the most basic level, referential integrity rules prevent the creation of orphan records in the table on the many side of the one-to-many relationship. After a relationship is established between a Customers table and an Orders table, for example, all orders in the Orders table must be related to a particular customer in the Customers table. Before you can establish referential integrity between two tables, the following conditions must be met: 1. The matching field on the one side of the relationship must be a Primary Key field or must have a unique index. 2. The matching fields must have the same data types (for linking purposes, AutoNumber fields match Long Integer fields). With the exception of Text fields, they also must have the same size. Number fields on both sides of the relationship must have the same size (Long Integer, for example). 3. Both tables must be part of the same Access database. 4. Both tables must be stored in the proprietary Access file (.ACCDB) format. (They cannot be external tables from other sources.) 5. The database containing the two tables must be open. 6. Existing data within the two tables cannot violate referential integrity rules. All orders in the Orders table must relate to existing customers in the Customers table, for example.
After you establish referential integrity between two tables, the Access Database Engine applies the following rules: 1. You cannot enter a value in the foreign key of the related table that does not exist in the primary key of the primary table. For example, you cannot enter a value in the CustomerID field of the Orders table that does not exist in the CustomerID field of the Customers table. 2. You cannot delete a record from the primary table if corresponding records exist in the related table. For example, you cannot delete a customer from the Customers table if related records exist in the Orders table (records with the same value in the CustomerID field). 3. You cannot change the value of a primary key on the one side of a relationship if corresponding records exist in the related table. For example, you cannot change the value in the CustomerID field of the Customers table if corresponding orders exist in the Orders table.
If you attempt to violate any of the preceding three rules and you have enforced referential integrity between the tables, Access displays an appropriate error message.
