Web 2.0 is a trend in the use of World Wide Web technology and web design that aims to facilitate creativity, information sharing, and, most notably, collaboration among users. These concepts have led to the development and evolution of web-based communities and hosted services, such as social-networking sites, wikis, blogs, and folksonomies (the practice of catgorising content through tags). Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but to changes in the ways software developers and end-users use the internet.

In situations like, where the copy on write bit of a page is set and that page is shared by more than one process, the Kernel allocates new page and copies the content to the new page and the other processes retain their references to the old page. After copying the Kernel updates the page table entry with the new page number. Then Kernel decrements the reference count of the old pfdata table entry.

In cases like, where the copy on write bit is set and no processes are sharing the page, the Kernel allows the physical page to be reused by the processes. By doing so, it clears the copy on write bit and disassociates the page from its disk copy (if one exists), because other process may share the disk copy. Then it removes the pfdata table entry from the page-queue as the new copy of the virtual page is not on the swap device. It decrements the swap-use count for the page and if count drops to 0, frees the swap space.

There could be thousands of concurrent users trying to read or modify the database, sometimes exactly the same data. If not for locking, your database would quickly lose its integrity. The following basic types of locks are available with SQL Server: - Shared locks: Enable users to read data but not to make modifications. - Update locks: Prevent deadlocking (discussed later in this session). - Exclusive locks: Allow no sharing; the resource under an exclusive lock is unavailable to any other transaction or process. - Schema locks: Used when table-data definition is about to change-for example, when a column is added to or removed from the table. - Bulk update locks: A special type of lock used during bulk-copy operations.
