Along with the RDBMS software, Oracle provides two utilities that you can use to back up and restore the database. These utilities are Export and Import.

The Export utility dumps the definitions and data for the specified part of the database to an operating system binary file. The Import utility reads the file produced by an export, recreates the definitions of objects, and inserts the data

If Export and Import are used as a means of backing up and recovering the database, all the changes made to the database cannot be recovered since the export was performed. The best you can do is recover the database to the time when the export was last performed.

Directives are used to pass optional settings to the ASP.NET pages and compilers. They typically have the following syntax: <%@ directive attribute=value [attribute=value] %> Directives are typically located at the top of the appropriate file, although that is not a strict requirement. For example, Application directives are at the top of the global.asax file, and Page directives are at the top of the .aspx files. Application directive: The Application directive is used to define application-specific attributes. It is typically the first line in the global.asax file. Assembly directive: The Assembly directive links an assembly to the application or page at parse-time. The Assembly directive is contained in either the global.asax file, for application-wide linking, or in a page (.aspx) or user control (.ascx) file, for linking to a specific page or user control. There can be multiple Assembly directives in any file. Each Assembly directive can have multiple attribute/value pairs. Control directive: The Control directive is used only with user controls and is contained in user control files (.ascx). There can only be a single Control directive per .ascx file. Import directive: The Import directive imports a namespace into a page, user control, or application, making all the classes and namespaces of the imported namespace available. Page directive: The Page directive is used to define attributes for the page parser and compiler specific to the page (.aspx) file. There can be no more than one Page directive for each page file. Each Page directive can have multiple attributes.

SSL (Secure Socket Layer) data transport requires encryption, and many governments have restrictions upon the import, export, and use of encryption technology.
If Apache included SSL in the base package, its distribution would involve all sorts of legal and
bureaucratic issues, and it would no longer be freely available.
Also, some of the technology required to talk to current clients using SSL is patented by RSA Data Security, who restricts its use without a license.
