Scalability Scalability is the ability of an application database to perform at an optimal level after the volume of data storage and the frequency of data retrieval have increased severalfold. By focusing energy on making the database design as efficient as possible, you will naturally improve the scalability of the database, because efficiency gains complement scale. Your data type choices for indexed fields affect the scalability of an application dramatically. As the volume of data increases, indexes and how quickly they can locate the desired data are relied on to provide adequate application performance. As a database designer, you must think long-term.

Sometimes, an event or property needs to be hidden from a control, but not removed entirely. For example, the ProgressBar control provides a Text property, which it inherits from the base Control class. This property can be used at the programmer s discretion, but it does not have any visible text because the ProgressBar doesn t provide a caption. For this reason, the Text property should be hidden from the Properties window. If you are defining or overriding a property, you can use the Browsable attribute to keep it from appearing in the Properties window. However, consider the TreeView control, which provides a Nodes collection. You may have noticed that the custom DirectoryTree control (first presented in 11) displays the Nodes property in the designer and allows it to be modified, although the display is built automatically at runtime based on the Drive property. The TreeView.Nodes property is not overridable, so you can t use the Browsable attribute. However, you can create a custom designer that ensures it won t appear at design time. Designers provide six methods from the IDesignerFilter interface that you can override to filter properties, events, and attributes. These methods are listed in Table 26-2.

Figure 3-2. Connecting to the Oracle database via TNS The code you ve written here connects to the Oracle database via what is called Transparent Network Substrate (TNS). Let s consider this scenario: Your Oracle database service could possibly be sitting on a computer server at hq.sales.a_very_long_name.com, listening on a particular port number. Instead of cramming all this information into the connection string, you could organize it in a file, stick a shorter label on it, and use that label to refer to it in your connection string. This is precisely what TNS does. This label is called the net service name and was what you ve used earlier for the Data Source attribute in your connection string.

Picture it: the database designer pats himself on the back for creating a brilliantly efficient and scalable database architecture. It will maintain itself, he says. And the database administrator laughs heartily. No database no matter how craftily designed or well implemented exists in a vacuum. Database administrators know this all too well, and their knowledge of common maintenance tasks (like backups and user administration) and replication is an invaluable asset to the design team. As a database administrator, you must work closely with the database designer and the business analyst to outline plans for the application s growth. The business analyst will provide a rough idea of the volume of customer data you can expect in a given time period. Through the database designer, you will see a clearer picture of the organization of this data across table structures. It is your job to accurately predict and plan for how this data should be handled in the short- and long-term. Given the limitations of the available hardware, you will make recommendations on how and how often the data should be backed up or consolidated. For example, if the database designer, at the behest of the application designer, has included tables for storing web site statistics, the database administrator would do well to analyze the expected web site traffic and provide a plan for consolidating the logged data at regular intervals into aggregate tables representing certain time periods. For many projects, functional requirements or environmental limitations may call for a distributed database architecture, with local slave database servers synchronizing with a master database (replication). The database administrator must work closely to plan the implementation of such complex systems.
