Cloud Connect provides the infrastructure required to host applications developed using technologies supported by Aptana Studio and is primarily based on Apache, with support for general web/Ajax, PHP, Ruby on Rails and Jaxer. Cloud Connect also supports Java-based web applications, which may be deployed and managed using the Cloud service.
The business logic and database access in such web and mobile applications is handled by the Omnis server. The Omnis server also can act as a hub between database servers, services based on Java and .Net and clients like Adobe Air & Flex, transferring data in the form of XML or Web services.
To use PHP with an HTML form, the URL of the PHP script is specified in the action attribute of the form tag. The target PHP file then accesses the data passed by the form through PHP's $_POST or $_GET variables, depending on the value of the method attribute used in the form. Here is a basic form handler PHP script that will display the ...
The connection object obtained from the connection pool is often a wrapper around the actual database connection. The wrapper understands its relationship with the pool, and hides the details of the pool from the application. For example, the wrapper object can implement a "close" method that can be called just like the "close" method on the ...
It is a layer of software that lies between the application code and the run-time infrastructure. Middleware generally consists of a library of functions, and enables a number of applications—simulations or federates in HLA terminology—to page these functions from the common library rather than recreate them for each application.

The data access tier contains physical database structures captured in the Uniface application model. Uniface ensures physical data access by encapsulating SQL in its DBMS connectors. Network and middleware access are encapsulated by the middleware drivers and the Uniface Router. The runtime engine executes the application components.
For example, WebDNA includes its own embedded database system. Either form of scripting (i.e., CGI or direct execution) can be used to build up complex multi-page sites, but direct execution usually results in less overhead because of the lower number of calls to external interpreters.
A database abstraction layer (DBAL [1] or DAL) is an application programming interface which unifies the communication between a computer application and databases such as SQL Server, IBM Db2, MySQL, PostgreSQL, Oracle or SQLite.
