Today, Dubai has emerged as a global city and a business hub. Although Dubai's economy was built on the oil industry, currently the emirate's model of business, similar to that of Western countries, drives its economy, with the effect that its main revenues are now from tourism, real estate, and financial services. Dubai has recently attracted world attention through many innovative large construction projects and sports events. This increased attention has highlighted labour rights and human rights issues concerning its largely South Asian workforce. Dubai's property market experienced a major deterioration in 2008 and 2009 as a result of the worldwide economic downturn following the Financial crisis of 2007–2010.

Dubai is also called 'The City of Skyscrapers'. The history of skyscrapers in Dubai began with the construction of the 149-metre (489 ft) Dubai World Trade Centre in 1979, which is regarded to be the first skyscraper in the city. At the time of its completion, it also stood as the tallest building in the Middle East. Since 1999, and especially from 2005 onwards, Dubai had been on an extremely large skyscraper building boom, with all 28 of its buildings over 200 metres (656 ft) tall completed after 1999. Dubai currently has 527 completed highrises,314 highrises currently under construction and 461 planned highrises.

 Cityscape

Dubai has a rich collection of buildings and structures of various architectural styles. Many modern interpretations of Islamic architecture can be found here, due to a boom in construction and architectural innovation in the Arab World in general, and in Dubai in particular, supported not only by top Arab or international architectural and engineering design firms design firms such as Al Hashemi and Aedas, but also by top firms of New York and Chicago.[93] As a result of this boom, modern Islamic - and world - architecture has literally been taken to new levels in skyscraper building design and technology. Dubai now boasts more completed or topped-out skyscrapers higher than 2/3 km, 1/3 km, or 1/4 km than any other city. A culmination point was reached in 2010 with the completion of the Burj Khalifa (Khalifa Tower), now by far the world's tallest building at 828 m (2,716 feet). The Burj Khalifa's design is derived from the patterning systems embodied in Islamic architecture, with the triple-lobed footprint of the building based on an abstracted version of the desert flower hymenocallis which is native to the Dubai region.[94] The completion of the Khalifa Tower, following the construction boom that began in the 1980s, accelerated in the 1990s, and took on a rapid pace of construction unparalled in modern human history during the decade of the 2000s, leaving Dubai with the world's tallest skyline as of January 4, 2010.

 

Tourism and retail

Dubai Mall is one of the largest malls in the world.
Tourism is an important part of the Dubai government's strategy to maintain the flow of foreign cash into the emirate. Dubai's lure for tourists is based mainly on shopping, but also on its possession of other ancient and modern attractions. As of 2007, Dubai was the 8th most visited city of the world. Dubai is expected to accommodate over 15 million tourists by 2015. Dubai is the most populous emirate of the seven emirates of United Arab Emirates. It is distinct from other members of the UAE in that a large part of the emirate's revenues are from tourism.
Dubai has been called the "shopping capital of the Middle East". Dubai alone has more than 70 shopping malls, including the world's 7th largest shopping mall, Dubai Mall. The city draws large numbers of shopping tourists from countries within the region and from as far as Eastern Europe, Africa and the Indian Subcontinent. While boutiques, some electronics shops, department stores and supermarkets operate on a fixed-price basis, most other outlets consider friendly negotiation a way of life.
Dubai is also known for its souk districts located on either side of the creek. Traditionally, dhows from the Far East, China, Sri Lanka, and India would discharge their cargo and the goods would be bargained over in the souks adjacent to the docks. Many boutiques and jewellery stores are also found in the city. Dubai is known as "the City of Gold" and Gold Souk in Deira houses nearly 250 gold retail shops. Dubai Duty Free at the Dubai International Airport offers merchandise catering to the multinational passengers using the airport.

Burj al Arab and 360 degree club
The Burj Al Arab (Arabic: برج العرب, "Tower of the Arabs") is a luxury hotel in Dubai, United Arab Emirates managed by the Jumeirah Group and built by Said Khalil. Its construction started in 1994 and ended in 1999. It was designed by Tom Wright of WS Atkins PLC. The hotel cost $650,000,000 to build. At 321 metres (1,053 ft) and 60 floors, it was the tallest building used exclusively as a hotel until being succeeded by Rose Rayhaan by Rotana in 23 December 2009, again in Dubai. The Burj Al Arab stands on an artificial island 280 metres (919 ft) out from Jumeirah beach, and is connected to the mainland by a private curving bridge. It is an iconic structure, designed to symbolize Dubai's urban transformation and to mimic the sail of a boat. Burj Al Arab characterizes itself as the world's only "7-star" property, a designation considered by travel professionals to be hyperbole. All major travel guides and hotel rating systems have a 5-star maximum, which some hotels attempt to out-do by ascribing themselves "6-star" status. Yet according to the Burj Al Arab's official site, the hotel is a "5-star deluxe hotel".
The Burj Al Arab was built to resemble the sail of a Dhow, a type of Arabian vessel. Its design features a steel exoskeleton wrapped around a reinforced concrete tower. Two wings spread in a V to form a vast mast, while the space between them is enclosed in a massive atrium by a teflon-coated fibreglass sail. During the day, the white fabric allows a soft, milky light inside the hotel, whereas a clear, glass front would produce blinding amounts of glare and a constantly increasing temperature. At night, both inside and outside, the fabric is lit by colour changing lights. Near the top of the building is a suspended helipad supported by a cantilever which has featured some of the hotel's notable publicity events.
The hotel's interior was designed by Kunan Chew. It features the tallest atrium lobby in the world at 180 metres. It is formed by the building's V-shaped span, dominates the interior of the hotel, and takes up over 1/3 of the interior space. Despite its size, the Burj Al Arab holds only 28 double-story floors which accommodate 202 bedroom suites. It is one of the most expensive hotels in the world. The cost of staying at a suite begins at $1,000 per night. The Royal Suite is the most expensive, at $28,000 per night.
One of its restaurants, Al Muntaha, is located 200 metres above the Persian Gulf, offering a view of Dubai. It is supported by a full cantilever that extends 27 metres from either side of the mast, and is accessed by a panoramic elevator. Another restaurant, the Al Mahara, which is accessed by a simulated submarine voyage, features a large seawater aquarium, holding roughly 35,000 cubic feet of water. The tank, made of acrylic glass in order to withstand the water pressure, is about 18 centimetres thick.

Sanitation issues
Currently, human waste is collected daily from thousands of septic tanks across the city and driven by tankers to the city's only sewage treatment plant at Al-Awir. Dubai's rapid growth means that it is stretching its limited sewage treatment infrastructure to its limits. Because of the long queues and delays, some tanker drivers resort to illegally dumping the effluent into storm drains or behind dunes in the desert. Sewage dumped into storm drains flows directly into the Persian Gulf, near the city's prime swimming beaches. Doctors have warned that tourists using the beaches run the risk of contracting serious illnesses like typhoid and hepatitis. Dubai municipality says that it is committed to catching the culprits and has imposed fines of up to $25,000 and threatened to confiscate tankers if dumping persists. The municipality maintains that test results show samples of the water are "within the standard".
