It is common for facilities of an activity center like those in Larry’s Leisure Center to have peak time. When the number of people using a facility exceeds its capacity, there will be peak time. Too many customers using the facility at the same time can ruin activity experience, and the bad experience can lead to customer loss. Therefore, business intelligence can be used to explore the existence of peak time and to find out matching solutions to make customers remain. In this report, the swimming pool and exercise class are taken as examples which are assumed to have peak time. All the numbers in the report are not real and just given as examples to show how to use the data recorded.

In the Pool table, each record means one entry into the swimming pool. Each record includes the exact date and time when the person uses the pool. It needs to count how many customers enter the swimming pool every three hours, and then divide the result by the capacity of the facility to calculate the ratio. When the ratio is far beyond one, it indicates this time period is the peak time and solutions are needed to solve the problem. The figure 1 shows the pool usage on a typical Friday and Saturday. Since the pool capacity is assumed to be 150 people, the 18:00 to 21:00 time period on Friday and 18:00 to 21:00 time period on Saturday are peak time. The ratio of the two time periods are 1.47 and 1.42 respectively, which are far beyond one and show too many people are sharing the crowded pool area at the same time. To convince the customers to relax themselves with the free space in the pool, some solutions have been raised:

(Figure 1)

Solutions to swimming pool peak time

* Limitation of pool usage at the peak time
In general, users can use the pool with no limited time, which causes some customers stay at the pool for too many hours. The problems can be relieved by limiting the using hours, for instance, each user only can use the pool for 2 hours every time on Friday and Saturday.

* Transfer users to other facilities
At the peak time of swimming pool, some other facilities are not fully used, as the Figure 2 shows. Therefore, the center can try to transfer pool users at peak time to other available facilities by some incentives, such as promotion activities, as well as invitations of gym experts. (Figure 2)

* Raise the price of swimming pool at peak time depend on demand-law
This approach can control the number of users, and it may transfer the original users at peak time to ordinary time. Effective as it is, some customers may feel dissatisfactory and leave.

* Build standby swimming pool
This pool does not open at ordinary time, and it is only used by users at peak time to reduce using space intension. This solution will lead to great cost initially, but it can solve the peak time problem for long run.

* Using number searching system
The center can link the database to the Internet. By doing that, any customer can search the current number of people using the swimming pool through their Iphones or computers before they come and then they can decide whether to go.

Moreover, the ExceriseClass table is also used to identify the peak time. Each record in the table indicates a class. The ExerciseClass_UserInformation table shows all the customer names and which class they belong to. Through calculating the number of customers in each class, it can be told which class has a peak time. According to data, there are more customers taking class on Friday Saturday and Sunday than on other days (Figure 3). Forty is assumed to be an ideal number of customers for an instructor to take care of. Moreover, it needs to be underlined that the center only has classes from Wednesday to Sunday and each one of the five instructors is responsible for one day’s class.

(Figure 3)

(Figure 4)

Solutions to Exercise class peak time

* Relate salary with popularity
Figure 4 shows a relationship between popularity of instructor. The degree of popularity an instructor to some degree determines the number of customers taking his class. Therefore, the direct solution is to relate the instructors’ salary with their popularity to motivate instructors. When the performance of all the instructors become competitive, customers will be distributed to other classes.

* Employee more instructors and set more classes
By doing so, the centre will be able to supply more classes for customers to choose at peak time and help to ease the burden on some crowded classes. Furthermore, the more employees, the more competition instructors will face. Competition is an effective threat to motivate instructors to work hard as well as to increase the efficiency of labor capital.

* Price discrimination
Eventually, this problem from the view of customers would be solved by different charge on different version of exercise, such as super-star teaching classes, general-teaching classes. The amount of students in popular classes would be decrease through this way.

Databases vs Data Warehouses

To keep these records organized, companies have separate database and data warehouses. A database is used for a single application, mostly for transactions. These transactions can range from payroll, inventory to sales and any other transaction the company needs on a daily bases. A data warehouse is used for multiple domains running simultaneously. A company should use a data warehouse to show how they are doing, in whole, rather than just in certain areas. The warehouse can also track business trends. Companies do not usually do not put all their information into one database because of the possibility of being hacked into easily by a Hacker and used for the wrong intent.

...huge amounts of data that is stored in a data warehouse that is used for the company’s employees. The employees will pull data that is needed each day to do their daily tasks. The company handles with several different parts that make up one part. Each part is labeled and has a barcode so that the part can be identified. The system that holds all of the data is basically a data warehouse that when an employee needs certain information about a single part can be retrieved from the data warehouse. The data warehouse is also used to follow the vendors to see how well they are doing. What I mean by see how they are doing is to follow how many good parts they build versus the bad parts that are built and sent to the company. The data that is recorded when a bad part is found leads to an inspection of the parts. When the inspection starts there are required steps that are followed and entered into the database. When this data is entered into the database it can show how many parts that have been inspected and how many were good and how many bad. With this company’s regular database that is being used every day and the data warehouse being used to see how the parts are being handle and how the vendors are doing, there are a lot of variables that are put in place for the company.

...Data Warehouse A data warehouse has many different processes that require several different technologies. Batch and transaction processing data has to first be taken out of the operational databases and then it can be cleaned up. Then the data is uploaded onto a relational database. Data warehouses are the basis for customer relationship management systems because they can be used for consolidating customer data and identifying areas of customer satisfaction and frustration. These warehouses can be used for fraud detection, production analysis, profit center, and corporate management. For retailers, a data warehouse can help identify customer demographics, identify shopping patterns, and improve mailing responses.

Modeling Data Warehouse

...Question: 1. When developing a successful data warehouse, what are the most important risks and issues to consider and potentially avoid? Data warehouse projects have many risks. Most of them are also found in other IT projects, but data warehousing risks are more serious because data warehouses are expensive, time-and-resource demanding, large-scale projects. Each risk should be assessed at the inception of the project. When developing a successful data warehouse, it is important to carefully consider various risks and avoid the following issues: • Starting with the wrong sponsorship chain. You need an executive sponsor who has influence over the necessary resources to support and invest in the data warehouse. You also need an executive project driver, someone who has earned the respect of other executives, has a healthy skepticism about technology, and is decisive but flexible. You also need an IS/IT manager to head up the project. • Setting expectations that you cannot meet. You do not want to frustrate executives at the moment of truth. Every data warehousing project has two phases: Phase 1 is the selling phase, in which you internally market the project by selling the benefits to those who have access to needed resources. Phase 2 is the struggle to meet the expectations described in Phase 1. For a mere $1 to $7 million, hopefully, you can deliver. • Engaging in politically naive behavior. Do not simply state that a data warehouse will help managers make better decisions...

...Data Warehouses and Data Mining Your Name DBM 384 May 13, 2013 Jim Cervi Data Warehouses and Data Mining Data warehouses serve an integral function within many different industries. In the government and law enforcement agencies this is especially prevalent. Vast amount of data and information from multiple sources is often collected by these agencies. This data and information must be put into a format that allows for workable details by the analysts (HowStuffWorks.com, 2012). Data mining and data warehouses provide these agencies with the ability to select specific data out of the large volumes of data available to the analyst Data Warehouse A data warehouse is a database of information collected from several resources, saved under a specific schema, at only one site according to (Siberschatz, Korth, & Sudarshan, 2011). This type of system is effective for government intelligence agencies in storing and categorizing the data sources. By effectively categorizing and storing the data, the data warehouse provides the analyst with a location where an effective query can produce tailored and specific results from vast stores of records. The data warehouse does this by linking the data sources through common threads. These threads are what allow the analyst to access the correct related information through the query. The data warehouse provides the structure of the data sources that the information will be categorized in. To be truly effective, a well-designed data...

...diagram, the following: Primary Data Warehouse and Data Mart. In this connection, explain the difference between ROLAP and MOLAP. A Primary Data Warehouse is a central repository of a database of a complete organization. It holds multiple subject areas and very detailed information. A Data Mart is a subset or an aggregation of the data stored to a primary data warehouse. It often holds only one subject area – for example, a specific department, finance or sales. It may hold more summaried data, and is typically smaller than a warehouse because of its employment on a different grain. Figure 1.1 illustrates the difference between data mart and a primary data warehouse. Since the data mart typically holds one subject area, it is much smaller than a primary data warehouse. These data marts can be viewed as small, local data warehouses replicating the part of primary data warehouse which is required by a specific domain or department.

...Data Warehouse is an application that collects data information to assist marketing and financial improvements through sales transactions and other dealings. This storage system holds large data files of consumers and other dealings within a company. The data collected from transactions assists companies with making decision that can better serve consumers as well as company reports. This stored information is more reliable because of its day-to- day transactions reports. Utilizing this type of system can be cost effective for storing large information for various companies. Once data is stored, the information is available to anyone, however it cannot be altered (Laudon & Laudon, 2013, p. 160). REI is building a data warehousing system, in order for the organization to have a better method to recognize each consumer’s interactions with the company. Information collected such as purchases and transactions through online, catalogs, stores and websites browsing is stored within the system.
