Database Concepts
Paper (Ch. 30 Web Technologies and DBMS)

The internet or web was created in 1989, the internet grew into the powerful information exchange service that it is today. It has expanded the world at a pace that has astounded many experts in this new field. This new technology brought forth many new ideas for better, faster, easier ways to communication between the different computer formats, so the experts had get together and create a universal language that would be accepted with all computer hardware systems. Most web pages today are written in HTML, XML, JAVA, JavaScript are just a few examples.
Websites now and in the past use the uniform resource locations (URL’s) to communicate inside the different browsers with the information or resources on a specific server. Without these locations, the information cannot be found or accessed, for example, to access Google.com, the browser needs to break down the information into an address to continue, and if the address is incorrect or cannot be located it will return a page not found error.
Hypertext markup language (HTML) is the most common language that spans across the different platforms. This language is pretty easy to learn using the free basic instructions available on the internet, and now most high schools teach HTML to their students so they can create their own webpage. Most personal webpages today are a great example of what is called a static web page. “An HTML document that is stored in a file is an example of a static Web page: the contents of the document does not change unless the file itself is changed.” (Connolly & Begg, 2010)
JavaScript is a very complex language and can used to create interactive web pages, but this language takes more practice and create havoc with your webpage if not executed properly. This along with XML, and JAVA is used for more complex applications including e-commerce sites where security is key. Web pages that use JavaScript and Java are what is considered to be a dynamic web page, “… the content of a dynamic Web page is generated each time it is accessed”. (Connolly & Begg, 2010)
Integration of a database in many online applications have changed the way information is stored, creating a new way of shopping for consumers, allowing companies to access data from multiple locations, changing how the world operates online as a whole.
Database which is used inside the web is called the database management system (DBMS), this allows the information stored securely also “a cost-effective solution that allows for scalability, growth, and changes in strategic directions, and helps reduce the costs of developing and maintaining of applications”. (Connolly & Begg, 2010)
There are many different types of applications available for web technologies that there is more created daily. If not for the internet, our world would be drastically different, but that is not the case. Each year new technologies emerge and will continue in this pattern for years to come.

...Database Concepts David Emersion DBM380 6/29/2015 Wade Fergus Database Concepts In an age when information is power, each business in the market place must make use of every tool at its disposal. Efficiency is the hallmark of any successful business. For a business to be efficient it must be the master of managing its own information. Time is money, and using an ineffective information management system is simply money down the drain. Quick access to accurate information is crucial to an organization’s success. Fortunately, businesses have a powerful weapon at their disposal – databases. Database Systems Every organization from small non-profit teams up to huge corporations supporting millions of customers must keep records of different types of data. These data can vary from inventory prices, to payroll, to medical records, and everything in between. The common challenges that these organizations face is keeping the data accurate, relatively easy to use, and secure. The solution to this problem is to use a database that fits the needs of the organization. A database is a system that houses data and metadata. Metadata is the information about the data and includes “information such as the name of each data element, the type of values (numeric, dates, or text) stored on each data element, and whether the data element can be left empty” (Coronel, Morris, & Rob, 2013, p. 7). A database system collectively...

...Database Systems DBM/380 July 13, 2015 James Cervi Database Systems When it is necessary to store and manage data, a database is used. A database is a collection of data organized in such a way that it can be easily stored, managed, and manipulated. “You can think of a database as an electronic filing system” (QuinStreet Inc, 2015). It is safe to assume that a large percentage of organizations use databases for managing the wide array of data within their company. Databases can keep track of data such as: employee records, consumer demographic and contact information, and company files. A database management system (DBMS) is the software that controls the movement of data in and out of the database, as well as within the database. While a database management system refers to the software used to control the data, the database refers to the body of data being stored. Types of databases can be classified in numerous ways. They can be classified by the user, such as: desktop database meant for a single user, or a work-group database meant for multi-users. There is also an enterprise database which is used by an entire organization. Databases can be categorized by location. A centralized database manages data at a single site, whereas a distributed database manages data in multiple locations. Another way of categorizing databases is by the type of data that is being stored. “General-purpose databases contain a wide variety of data used in multiple disciplines” (Coronel,...

Database Normalization and Logical Process Concept Paper

...Database Normalization and Logical Process Concept paper This short paper will explain with a simple example the process and the need of normalization in the most of the business databases. Complete proposal break down (Timeline phases, Financial phases) will be submitted per management request. Overview At first any database should be designed with the end user in mind. Logical database design, also referred to as the logical model, is the process of arranging data into logical, organized groups of objects that can easily be maintained. The logical design of a database should reduce data repetition or go so far as to completely eliminate it. The needs of the end user should be one of the top considerations when designing a database. We should remember trough all design process that the end user is the person who ultimately uses the database. There should be ease of use through the user's front-end tool (a client program that allows a user access to a database), but this, along with optimal performance, cannot be achieved if the user's needs are not taken into consideration. Some user-related research and design considerations in any business database include the following: What data should be stored in the database? How will the user access the database? What privileges does the user require? How should the data be grouped in the database? What data is the most commonly accessed? How is all data related in the database? What measures should be taken to ensure accurate data...

...1. What are the advantages of a declarative language as opposed to a procedural language? ANSWER: The advantage of declarative programming languages is mainly two-fold. The programs are concise; this makes it easy even for non-programmers to obtain solutions. In the SQL example above, an analyst or business support person can get the desired information. Similarly, laypersons can write acceptable web pages with simple HTML and CSS commands. The second advantage of the declarative programming model is that repetitive imperative code that indicates how to solve things is provided in the computer system behind the scenes. Such code can be made highly efficient and can incorporate the best ideas from computing. It can take advantage of parallelism 2. What advantages might a procedural language have over a declarative language? ANSWER: Procedural programming is used for developing simple applications. The languages that use the procedural programming methodology include Pascal and C languages. Some of the benefits of the procedural programming methodology are: (1) Easy to read program code. (2) Easy maintainable program code as various procedures can be debugged in isolation. (3) Code is more flexible as you can change a specific procedure that gets implemented across the program. 3. Why do you think cross joins are allowed as a legitimate join? What uses can you see for joins? ANSWER: I think that a cross-join would be optimized in the client library, so that less...

...Exploring the Latest ANSI and ISO Standard ANSI (American National Standards Institute) was founded in 1918, it is a voluntary organization composed of over 1,300 members (including all the large computer companies) that creates standards for the computer industry. For example, ANSI C is a version of the C language that has been approved by the ANSI committee. To a large degree, all ANSI C compilers, regardless of which company produces them, should behave similarly. In addition to programming languages, ANSI sets standards for a wide range of technical areas, from electrical specifications to communications protocols. The ISO was founded in 1946 and is currently headquartered in Geneva, Switzerland. Its mission at its inception was to create international standards regarding the threads of screws used for manufacturing world-wide. As needs for other standards arose, the ISO (then called the International Standards Organization, hence, ISO) stepped in to handle the task, and their influence crept into all areas of manufacturing and services. The primary focus for the ISO hasn't really been in the electrical and electronics area. Many of the standards set up in those areas were created by an older standards-setting organization called the International Electrotechnical Commission, or IEC, also based in Geneva. However, the ISO has responded to the needs of computing standards by forming a joint committee with the IEC dealing with information technology. The ISO has published...

The major topics of the database are: Lease Form (tracks leases of one apartment complex); Rent Payment Form (tracks rent payment of one apartment complex); Maintenance Request Form (tracks requests for maintenance and apartment manager’s resolution); Sample Quarterly Report (shows revenues and expenses of a particular building, address). STATEMENT OF WORK Project Name: Wild Wood Apartments June 21, 2014 • History: The Wild Wood Apartments are made up of 20 different complexes in Washington, Oregon, California and Idaho with each complex containing from 10 to 60 separate apartments. Leases are from 6 months to a year and the company’s practice is to hire one of the tenants to run the complex, collecting rent, conducting repairs, etc. The company requires a quarterly report to track the lease occupancy, rent payment, maintenance, and revenue and expenses; all of which is done in paper form. The forms are considered time consuming by the property managers, and the corporate office has concerns over their accuracy. A centralized database is being considered to simplify and better manage this data. • Scope: The contractor will include hardware, website, software and data storage support for the headquarters and all property offices that belong to Wild Wood Apartments. The main storage for the data will be offsite and the contractor is responsible for maintaining it. • Constraints: The contractor and the headquarters office of Wild...
