Multitier architecture

In software engineering, multitier architecture (often referred to as n-tier architecture) is a client–server architecture in which presentation, application processing, and data management functions are physically separated. The most widespread use of multitier architecture is the three-tier architecture.

N-tier application architecture provides a model by which developers can create flexible and reusable applications. By segregating an application into tiers, developers acquire the option of modifying or adding a specific layer, instead of reworking the entire application. A three-tier architecture is typically composed of a presentation tier, a domain logic tier, and a data storage tier.

While the concepts of layer and tier are often used interchangeably, one fairly common point of view is that there is indeed a difference. This view holds that a layer is a logical structuring mechanism for the elements that make up the software solution, while a tier is a physical structuring mechanism for the system infrastructure.

Sehnsucht (Rammstein album)

Sehnsucht (German for "yearning", see Sehnsucht) is the second album by German industrial metal band Rammstein, released on 25 August 1997.

The album booklet folds out to reveal six different covers, one for each band member (each photo depicting the member with bizarre facial-wear made out of ordinary kitchen objects like spatulas, spoons, forks etc.). The cover most commonly seen features Till Lindemann with an egg-lifter worn as a muzzle and bent forks over his eyes worn as sunglasses. The cover art was created by Austrian artist Gottfried Helnwein, who also created the cover for the Scorpions' Blackout album, which is very similar to the Sehnsucht cover and even the forks in both covers are the same. Sehnsucht is the only album entirely in German to be certified platinum by the RIAA in the US.

Track listing

All songs written and composed by Rammstein, except "Sehnsucht" written by Rammstein and Orgasm Death Gimmick and "Tier", written by Rammstein and Jürgen Engler. 

Eternal Darkness

Eternal Darkness: Sanity's Requiem is a psychological horror action-adventure game developed by Silicon Knights and published by Nintendo for the GameCube in 2002. The game was originally planned for the Nintendo 64. The game's setting is centered on a mansion in Rhode Island—the home of protagonist Alexandra Roivas' grandfather—and a book that Alexandra finds there. It utilizes a third-person view in which the player must navigate a number of locations as twelve characters spanning different time periods, as well as "sanity effects" to enhance the gameplay.

Though not a commercial success, Eternal Darkness was widely praised, winning numerous awards. While a direct follow-up was cancelled by the copyrights holder Nintendo, and Silicon Knights bankrupted and disbanded, the game's writer and director Denis Dyack has been attempting to make a spiritual successor titled Shadow of the Eternals.

Plot

The action in Eternal Darkness is divided between four principal locations. The game skips back and forth through time when the player begins or ends each chapter. The locations include the Forbidden City in Persia, a Cambodian temple in Angkor Thom, the Oublié Cathedral in Amiens, France, and the Roivas family mansion with the Ruined City of Ehn'gha in Rhode Island, United States.
