The replication model in SQL Server 7 provides a very powerful but easy way to manage distributed information. In this section, we ll look at the architecture of the replication model and explore how it can best be implemented. Let s start with an overview.

Microsoft included many features and technologies in SQL Server 7 to make its replication features powerful yet easy to administer. Basic design goals include the following: w High performance and scalability In order to keep large quantities of data synchronized, you must use efficient methods of transferring information. Common ways to meet this requirement include sending only the changes that occur in a database instead of the database itself. Reliability Businesses rely on replication to ensure that their databases are consistent and up-to-date. The information stored in these repositories is critical for decision support and online transaction processing (OLTP). For this reason, the replication features of SQL Server must be robust and reliable, even when there is a high volume of transactions. One way to ensure that information is kept consistent is known as two-phase commit. This operation ensures that data that must be updated on multiple servers is either all committed or all rolled back, thus preventing inconsistencies. Simplified administration A common problem relative to working with other RDBMSs is that establishing and maintaining replication can be quite complicated. Some of the complexity is due to the nature of the operations involved. Some of it, however, is due to non-user-friendly tools and features. As we ll see later in this section, Microsoft has designed SQL Server 7 to be easy to administer. Through the use of wizards and the Enterprise Manager console, most common replication scenarios can be quickly set up by systems or database administrators.

Interoperability Although it would be nice if all of your database servers ran on a single platform, the reality in most businesses is that heterogeneous systems are often used to store data. These data repositories may include standard text files, spreadsheets, relational database servers, and mainframes. Although their functions may at first seem very different, the end goal is the same to store information and make it available to users. SQL Server 7 includes many features that support the interchange of information between these various data sources, as well as with other installations of SQL Server.

These features make replication readily accessible in SQL Server 7 and a good solution for distributing information.
Planning for Replication
Before you decide you want to implement replication in your environment, you should determine the business reasons. Implementing and maintaining replication will take time, effort, and network resources. Additionally, the overhead associated with replication can reduce overall database server performance. As you re deciding whether or not to implement replication as part of your data protection strategy, be sure to make the following considerations: w Evaluate your database needs. The main reason to use replication is to distribute information across slow network connections. If you require information in multiple locations to be kept synchronized, you should determine how much lag time between updates is acceptable. In many environments, data might need to be updated only a few times per day. If real-time concurrency of all servers is truly necessary, you should be prepared for the time and expenses required. In some cases, replication is a good solution for distributing data. In others, however, it might be more practical to use alternate means. Evaluate your network topology. Distributing information between remote servers requires network bandwidth. To keep your servers synchronized, you must have enough data throughput capacity on your slowest network links to support this information. Before you decide to deploy multiple servers with replication, you should estimate the amount of data that will change in each location. Based on these estimates, you can determine an approximate bandwidth requirement. Finally, you must factor in the other uses for these network connections. If, for example, users require a WAN connection for access to the company intranet, all the bandwidth in the connection might not be available for transferring database changes. Consider all the alternatives. If you need to make information available in multiple areas, make sure that replication is the appropriate method. For example, a retail establishment might require only daily sales summaries to be transmitted to the corporate office. If this is the case, then simply sending summary database information or even generating regular reports would be more useful. If you re trying to use replication primarily for backup purposes,
