Online analytical processing

Online analytical processing, or OLAP, is an approach to answer multi-dimensional analytical queries swiftly in computing. OLAP is part of the broader category of business intelligence, which encompasses relational databases, report writing and data mining. Typical applications of OLAP include business reporting for sales, management reporting, business process management and forecasting, financial reporting and similar areas, with new applications emerging, such as agriculture; the term OLAP was created as a slight modification of the traditional database term online transaction processing. OLAP tools enable users to analyze multidimensional data interactively from multiple perspectives. OLAP consists of three basic analytical operations: consolidation, drill-down, slicing and dicing. Consolidation involves the aggregation of data that can be accumulated and computed in one or more dimensions. For example, all sales offices are rolled up to the sales department or sales division to anticipate sales trends.

By contrast, the drill-down is a technique. For instance, users can view the sales by individual products. Slicing and dicing is a feature whereby users can take out a specific set of data of the OLAP cube and view the slices from different viewpoints; these viewpoints are sometimes called dimensions Databases configured for OLAP use a multidimensional data model, allowing for complex analytical and ad hoc queries with a rapid execution time. They borrow aspects of hierarchical databases and relational databases. OLAP is contrasted to OLTP, characterized by much less complex queries, in a larger volume, to process transactions rather than for the purpose of business intelligence or reporting. Whereas OLAP systems are optimized for read, OLTP has to process all kinds of queries. At the core of any OLAP system is an OLAP cube, it consists of numeric facts called measures. The measures are placed at the intersections of the hypercube, spanned by the dimensions as a vector space; the usual interface to manipulate an OLAP cube is a matrix interface, like Pivot tables in a spreadsheet program, which performs projection operations along the dimensions, such as aggregation or averaging.

The cube metadata is created from a star schema or snowflake schema or fact constellation of tables in a relational database. Measures are derived from the records in the fact table and dimensions are derived from the dimension tables; each measure can be meta-data associated with it. A dimension is. A simple example would be a cube that contains a store's sales as a measure, Date/Time as a dimension; each Sale has a Date/Time label. For example: Sales Fact Table +-------------+----------+ | sale_amount | time_id | +-------------+----------+ Time Dimension | 2008.10| 1234 |----+ +---------+-------------------+ +-------------+----------+ | | time_id | timestamp | | +---------+-------------------+ +---->| 1234 | 20080902 12:35:43 | +---------+-------------------+ Multidimensional structure is defined as "a variation of the relational model that uses multidimensional structures to organize data and express the relationships between data". The structure is broken into cubes and the cubes are able to store and access data within the confines of each cube.

"Each cell within a multidimensional structure contains aggregated data related to elements along each of its dimensions". When data is manipulated it remains easy to access and continues to constitute a compact database format; the data still remains interrelated. Multidimensional structure is quite popular for analytical databases that use online analytical processing applications. Analytical databases use these databases because of their ability to deliver answers to complex business queries swiftly. Data can be viewed from different angles, which gives a broader perspective of a problem unlike other models, it has been claimed that for complex queries OLAP cubes can produce an answer in around 0.1% of the time required for the same query on OLTP relational data. The most important mechanism in OLAP which allows it to achieve such performance is the use of aggregations. Aggregations are built from the fact table by changing the granularity on specific dimensions and aggregating up data along these dimensions, using an aggregate function.

The number of possible aggregations is determined by every possible combination of dimension granularities. The combination of all possible aggregations and the base data contains the answers to every query which can be answered from the data; because there are many aggregations that can be calculated only a predetermined number are calculated. The problem of deciding which aggregations to calculate is known as the view selection problem. View selection can be constrained by the total size of the selected set of aggregations, the time to update them from changes in the base data, or both; the objective of view selection is to minimize the average time to answer OLAP queries, although some studies minimize the up

W. Dennie Spry Soccer Stadium

W. Dennie Spry Soccer Stadium is a soccer-specific stadium located on the campus of Wake Forest University in Winston-Salem, North Carolina where it is home to the Wake Forest Demon Deacons men's soccer and women's soccer teams. Opened in 1996, W. Dennie Spry Soccer Stadium is home to the Wake Forest men's and women's soccer programs. Considered one of the top soccer facilities in the country, the 3,000-seat stadium is considered a jewel in Wake Forest's family of athletic facilities and gives the Demon Deacons a true home field advantage; the Spry Stadium complex features a lit natural grass playing field along with two lit natural grass practice fields. The facility includes a state-of-the-art scoreboard and sound system, locker rooms for both the men's and women's teams, a pressbox with rooftop observation deck and concession stands; the Deacons play in front of packed crowds, as the campus and local communities support the men's and women's teams. A strong contingent of students can always be found on the hill overlooking the north side of the stadium.

Spry Stadium has hosted several major soccer events. The ACC Tournament has been contested four times at Spry: the women's tournament was held there in 1997, while the men's event was held at the venue for three straight years from 1998 to 2000. In March 2001, Spry Stadium hosted a Major League Soccer exhibition match between the Miami Fusion and D. C. United and an exhibition match between the United States U-17 National Team.

Meadows Mall

Meadows Mall is a shopping mall in Las Vegas, Nevada on 84 acres. It is a two-story enclosed mall with 960,000 ft² of space; the mall has 5 anchors. It is surrounded by 4,900 surface parking spaces in four different color-coded lots, its anchor stores are Curacao, a Dillard's clearance outlet, J. C. Penney, Macy's. Dayton-Hudson Corporation began planning the mall in 1973; that year and again in 1974, the Las Vegas City Commission voted against the mall as some members felt that the project should be moved to a better location. In early 1974, Dayton-Hudson won a district court order which required the city to grant a necessary zoning variance; the City Commission appealed the ruling to the Nevada Supreme Court. In 1975, the Supreme Court forced the City Commission to grant the variance. Groundbreaking took place in May 1976, construction took more than two years, at a cost of $20 million. Ernest W. Hahn Inc. was the general contractor. More than 1,200 people worked on the mall during construction; the mall was designed by architectural firm Charles Kober & Associates, which chose desert colors and tones for the building.

The mall opened in 1978, at a time when The Boulevard Mall was the city's only other major indoor mall. In September 1978, after the mall's opening, Dayton-Hudson announced that the mall would be sold as part of corporate downsizing. At the time of opening, the mall included 7,600 parking spaces and two anchor stores: Diamond's and The Broadway. Sears and JCPenney stores were scheduled to open in 1979, thus completing the mall. 3,000 people were expected to be employed at the mall. The mall's name is derived from the English word for Las Vegas: Meadows. Dillard's opened at the mall in 1984. In December 1993, the mall was temporarily evacuated after a teenage boy made bomb threats with what turned out to be a fake bomb; the mall received a renovation in 1995. That year, the executive director of the Las Vegas Indian Center criticized the mall's carousel for featuring a carving of an American Indian head on the back of one of the ride's horses, calling it "culturally offensive". On March 1, 1996, a no-smoking policy was instituted inside the mall due to requests from customers.

A partial renovation took place in 1997, included a new overflow parking lot added near the mall's JCPenney store. At the time, the mall was composed of 123 stores, included one restaurant and a 14-vendor food court; that year, the mall designated parking spaces near its entrances as "Stork Parking," reserved for expectant mothers. General Growth Properties acquired the mall in May 1998. At that time, the mall contained 951,000 sq ft. By May 1999, General Growth Properties had increased the mall's occupation to 95 percent. In June 2003, General Growth Properties began a multimillion-dollar renovation that would include brighter indoor lighting, tile flooring, a new color scheme, a new stone facade, exterior paint, enhanced landscaping, as well as three new escalators and upgrades to the food court; the company felt that the mall, with its dated 24-year-old presentation, needed a contemporary look to compete. The mall remained open with most of the work being done during night hours. With 99 percent of the renovations complete, the mall celebrated its grand reopening on November 21, 2003, with a ribbon-cutting ceremony that morning, followed by live jazz performances and a live children's show featuring Strawberry Shortcake.

Several new stores had been added during the renovations, which included new bathrooms and a revamping of the food court. The mall contained 947,370 sq ft at the time. In conjunction with Valley Hospital Medical Center and the Summerlin Hospital, the Meadows Mall added the 1,640 sq ft Healthy Living Play Area in November 2004, as a way to educate children about healthy lifestyles. In December 2004, a man was arrested on eight counts of illegally accessing people's credit card accounts after falsely telling them that he was a millionaire family member of the non-existent Meadows family, whom he claimed were the owners of the mall. Tomfoolery, a 24-hour restaurant and bar with five slot machines, opened on the mall's second floor in April 2005. Tomfoolery was approved for 10 additional slot machines in August 2005, despite opposition from local families. On March 9, 2007, the mall remained open during a police and SWAT search for a suspect who fled into the mall after a traffic stop. In 2014, Dillard's closed the 100,000 sq ft first floor of its 180,000 sq ft store in the Meadows Mall, converted its second floor into a clearance outlet for unsold merchandise from other Dillard's stores.

In March 2015, the Las Vegas Review-Journal reported, "With regional shopping centers proliferating, the Meadows is becoming an odd mall out — the shopping center without a distinct personality or demographic segment. As a result, retail experts say, the mall faces a crossroads at which it must soon chart a new direction." In 2015, Sears Holdings spun off 235 of its properties, including the Sears at Meadows, into Seritage Growth Properties. In September 2015, the mall was 97-percent; that month, VegasInc reported that despite the 2003 renovation, "it looks like a typical mall from the'90s." Curacao opened in Dillard's vacant first-floor space in October 2016, attracted 40,000 customers on its opening day. In June 2018, the mall's Macy's store opened an off-price store-within-a-store. Seritage leased part of the Sears first floor to Round One Entertainment, which opened a store in the space in November 2019; that month, it was announced that Sears would be closing its Meadows Mall location as part of a plan

Defence Services Technological Academy

The Defence Services Technological Academy, located in Pyin-Oo-Lwin, Myanmar, is the premier technological university of the Myanmar Armed Forces. One of the most selective universities in the country, the academy offers various Bachelor of Engineering degrees to male cadets only. Upon graduation, most DSTA cadets are commissioned as Engineering Officers with the rank of Lieutenant in one of the three branches of Burmese armed forces--army and air force; some qualified cadets may choose to pursue further education in Yangon Technological University, Mandalay Technological University or abroad. The Defence Services Technological Academy was established as the Defence Services Institute of Technology in 1st February 1993 at Pyin Oo Lwin when all civilian colleges and universities in Myanmar were shut down by the military government, following the 1988 nationwide uprising; the military went on to establish a parallel system of colleges and universities for itself, including DSTA, Defence Services Medical Academy, Defence Services Institute of Nursing and Paramedical Science.

Lt. Col. Win Myint was assigned to carry out this duty; the first "intake" of students graduated with Bachelor of Engineering degrees in 1999. The academy's graduation ceremonies, as with those of all other military-run academies, are attended by the highest ranks of the military government; as one of the elite military academies in Union of Myanmar, the academy maintains a rigorous selection process, including physical fitness testing, ability for teamwork and comradeship screening and general interviews. The entrance selection process takes about 5 to 7 days at Myanmar Military Officer Selection Board in Yangon before 18th intake and after 18th intake, the entrance selection process takes about 5 days at "Officer Testing Team" in Nay Pyi Taw. According to official statistics, DSTA takes 1 out of 145 applicants at selection process; the academy offers six-year Bachelor of Engineering degree programs in various disciplines, but in Mechanical Engineering and Electrical Engineering in addition to required cadet training.

Cadet training includes basic military skills, including leadership, through a military programs that begins on their first day at DSTA. Cadets divided into one of two battalions--Anawrahta or Bayinnaung; each battalion is divided in the structure of Burmese army. Most military training takes place during the winter, with new cadets undergoing Cadet Basic Training--or Beast Barracks—the first year, followed by Cadet Field Training in the second year. Cadets are housed in barracks and have leadership positions and responsibilities throughout the academic year; the DSTA campus is located in Wetwun, near Pyin-Oo-Lwin on the Mandalay-Lasho highway, on the opposite side of town from its brother school, Defence Services Academy. DSTA is part of the military education facilities established around Pyin Oo Lwin area, home to Defence Services Administration School, the Army Training Depot.

Badulla is the main city of Uva Province situated in the lower central hills of Sri Lanka. It is the capital city of the Badulla District. Badulla is located in the southeast of Kandy encircled by the Badulu Oya River, about 680 m above sea level and is surrounded by tea plantations; the city is overshadowed by the Namunukula range of mountains. It was a base of a pre-colonial Sinhalese local prince who ruled the area under the main King in Kandy before it became part of the British Empire, it became one of the provincial administrative hubs of the British rulers. The city was the end point of upcountry railway line built by the British in order to take tea plantation products to Colombo. Badulla is about 230 km away from Colombo towards the eastern slopes of the central hills of Sri Lanka. There are multiple routes to Badulla from Colombo and Galle. From Colombo, one can travel via Ratnapura, Haputale and Hali Ela along A4 and A16 to Badulla, which may take 5–6 hours. From Kandy there are two routes: either via Nuwara Eliya.

From Galle, the best route is via Matara, Wellawaya, Ella and Hali Ela. All routes are scenic and one can see splendid views of the geography, which changes while travelling. Badulla and its surroundings are recommended for eco-tourists as Horton Plains National Park and the Knuckles mountains are a few hours away. Badulla was an isolated village until the British built roads from Kandy and Nuwara Eliya in the mid 19th century, as part of the growing plantation economy. By the 20th century Badulla had become a regional hub, with the British establishing it as the capital of Uva Wellassa, now known as the Uva Province. Badulla still has a number of British colonial buildings existing, including the Badulla railway station, which opened in 1924; the station is the last train station on the Main Line, which served as the rail line by the British to transport tea collected from the Badulla district to Colombo. Badulla district is one of the leading tea producing districts, second only behind the Nuwara-Eliya District.

The town has grown since the country's independence from 13,000 in 1946, to 38,000 in 1977 and 47,587 in 2011. Badulla is a multi-national city with the ancient Muthiyangana Temple situated in its heart; the Catholic Church has a diocese headquartered here. It is emerging as a well developed city in Sri Lanka with a state of the art provincial hospital and many more developments. Muthiyangana temple is an ancient Buddhist temple located in the middle of Badulla, it is regarded as one of the Solosmasthana, the sixteen sacred places in Sri Lanka, believed by Buddhists to have been visited by Gautama Buddha. Badulla Kataragama Devalaya is an ancient devalaya, situated in Badulla town, it is one of shrines dedicated to Sinhalese deity Kataragama deviyo. Old Welekade Market is a historic colonial building, situated in middle of the Badulla town, it was built in 1889 by British. Dunhinda Falls, a 64 metres high waterfall, is located 5 kilometres north of Badulla; this is one of the most popular waterfalls of Sri Lanka, mentioned in several famous songs and works of literature.

It draws many foreign tourists to the region. Bogoda ancient wooden bridge is one of the oldest surviving wooden bridges in the country and is located 13 kilometres south of Badulla, close to the town of Hali-ela. Demodara railway station is between Udoowara railway stations. Demodara railway station is famous because the railway turns from the platform, goes under the railway station in the tunnel. St Mark's Church, built in memory of Major Thomas William Rogers, Assistant Government Agent of Uva Province, who died 7 June 1845 after being struck by lightning at the Sherwood Estate in Haputale, it was the first church to be consecrated by the first Bishop of Colombo Rev. James Chapman.
