Now that we've discussed how an application connects to the Web and how it can connect to a database, you should have a basic understanding of how a web application server works. Many web database connectivity tools offer native database access to provide performance boosts. The fastest way to access a database is to directly interface with the file natively.

This is probably the highest performance method for accessing a database outside of the native database drivers, but it's also currently limited to the Windows NT platform. The support forĭatabases is quite limited, albeit to the most popular database platforms (MS-SQL Server, Oracle, and the like). The snap-in components for different databases are known as providers and they are far more sophisticated than the ODBC and JDBC drivers. Microsoft's newest technology for database access is OLE-DB, which is part of their entire enterprise COM architecture.

This is the connection method of choice for Java applications, but drivers exist for fewer databases than with ODBC. Sun released JDBC, the Java equivalent of ODBC, shortly after Java was released. ODBC is slower than newer technologies such as OLE-DB, but has the widest support of both databases and applications that can use ODBC to access a database. The snap-in components of ODBC are know as ODBC drivers, and they can be found or bought for virtually every common database platform. This technology was developed jointly by IBM, Microsoft, and a number of other manufacturers in the late 1980s to make it easier to interoperate between their various database products.
The most common general database protocol is Open DataBase Connectivity (ODBC). All of these limits, however, are typically countered by the relative ease of building web database applications using the common protocols. And in some cases, there's no way to translate database-specific commands and procedures into the common protocol. Another problem is speedall the translations between the common protocol and the database mean additional processing time. This is a very difficult task, and there are simply no components available for some databases on certain platforms and under certain protocols. The main disadvantage is that someone has to make the components to snap in for each database product. There are several downsides to this sort of common database access framework. The underlyingĬommunication between the application and the database is not effected, and the specific database component takes care of the details. This means that if you need to switch your data from a low-end database to a more sophisticated one, the only necessary step to access the data in its more sophisticated database format is to snap in the appropriate component for the new database. An application uses the general database access protocol to connect to a specific source of data and the "snap in" for that particular type of database handles the translation from the common protocol to the native language of the database, and vice-versa.
General database access protocols are designed so that the detailed information about a particular database product can be "snapped in" to a common framework without worrying about If you're a programmer, odds are that you'd prefer to use a single database access protocol that can handle databases from a number of different vendors rather than learning something completely different for each one. The fundamental problem is not only that applications need to be able to access databases, but that they might even need to access several different kinds of databases.

Why would you? But many software engineers have thought about it for you and produced several different technologies for allowing applications and databases to talk to each other. You probably have never thought much about how applications connect to databases. SQLStructured Query Language enables applications to communicate with relational databases primarily for data manipulation. It's powerful, but limited to the NT platform.
