1. After reviewing the history on SQL server, I have found that there have been 7 revisions of the SQL standard. In the most recent, SQL 2011, there were many new non-temporal features. You have DELETE in MERGE, Pipelined DML, CALL enhancements, Limited fetch capability, Collection type enhancements, non-enforced table constraints, and window enhancements. With SQL:2011 replacing SQL:2008 as the standard in December of 2011, there were also some new DDL features that improved the usability of generated and identity columns.

2. SQL Express allows certain features that are available in the regular edition. The following are major features that are supported in SQL Express: Stored Procedures, Views, Triggers, Cursors, sqlcmd and osql utilities, Snapshot Isolation levels, Native XML support (including XQuery and XML Schemas) Transact-SQL language support, and dedicated administrator connection. In Oracle Express, you are able to use a browser-based interface to administer the database, create tables, views, and other database objects, import, export, and view table data, run queries and SQL scripts, and generate reports. DB2 Express is a no-charge community edition of DB2 data server and is ideal for small businesses and multi-branch companies. It includes self-managing capabilities and includes all of the core features of the larger DB2 editions which include Data Studio, Time Travel Query, PureXML and compression backup. After looking over all of the specs of each of these programs, I believe that SQL and Oracle are the top two. When we look into the finer details of things, my personal preference would be to go with SQL Express as there are many reviews that support it.

...Database concepts research assignment week 9 Don't use Personal Identifiable Information (PII) in your password such as, Name, User name, Birthday, Pet’s name or Child's name. Don't use any word that can be found in the dictionary as your full password. Don’t use the same password for online banking that you use for social networking or email. Don’t give your password to someone over the phone. Try to use special characters such as non-alphabetic characters. Try to create passwords at with at least eight characters. Try to use a password vault application to protect and help manage your many passwords. Try to change your most critical passwords on a regular basis. The Windows operating system already has authentication functionality built-in. It has to do so. And if you're in a domain environment, there are special computers, called Domain Controllers, where authentication actually takes place. Those systems tend to be treated more security than regular servers, even SQL Servers. And therefore, if the username/password combinations are going to be stored on the most secure systems in the domain, that would be on the domain controllers (as a side note, a hash is what is actually stored there, not the password itself). If you let Windows do the authentication, then SQL Server doesn't have to store anything related to a username/password combination. And it's up to Windows to check the security. In other words, SQL Server is handing off this sort of authentication to processes......

...Mary Easterling 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, 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......

System implementation efforts offer extraordinary challenges to information technology professionals and the organizations impacted by the implementations. A successful implementation can reap vast rewards in organizational strengths and efficiencies. A failure can drain an organization of people, funds and vitality. Therefore, many people have been affected for reasons of success and failure experienced with the implementation. based on this case study rapid-implementation period of nine months to be implemented when the implementation of this system can be carried out as planned. The step of planning was: - 1. Interaction of technology and organization - a broad concept that laid the foundation for many other factors to consider. 2.

...List the major topics for this database. 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...

...Addison Huggins Unit 4 Research assignment 1 July 24, 2014 The definition of Functional dependency is when one attribute in a relation uniquely determines another attribute. This can be written A -> B which would be the same as stating "B is functionally dependent upon A." While I was looking online for a good example of Functional dependency I came across one, the example comes from the website. in this example and I quote ” In a table listing employee characteristics including Social Security Number (SSN) and name, it can be said that name is functionally dependent upon SSN (or SSN -> name) because an employee's name can be uniquely determined from their SSN. However, the reverse statement (name -> SSN) is not true because more than one employee can have the same name but different SSNs.” Transitive dependency occurs when there is an indirect relationship that causes a functional dependency. While looking this up on the internet, it is hard to find a good example but in time I did. The example comes from and from the website the example is and I quote “”A -> C” is a transitive dependency when it is true only because both “A -> B” and “B -> C” are true.” Demoralization is a strategy that database managers use to increase performance in their database. This is used to reduce certain types of problems that might......

...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......

...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,...

...Huffman Trucking needs a better way to track the maintenance on their fleet of tractors, trailer and the roll-on/roll-offs. The fleet has to undergo periodic maintenance. Plan Putting the equipment's maintenance history, the parts used and vendor information into one database will save Huffman Trucking time and money. The database can include parts inventory information, parts catalogue information, the vendors used and their associated information, and parts purchasing history. The database will include all the maintenance history on each piece of equipment, such as the maintenance of the equipment itself, tire maintenance, the type of maintenance and the maintenance work orders. Conclusion Building a database saves money on maintenance by reducing redundant information and improving record keeping. Both the service and accounting departments will be able to utilize this database to keep track of parts purchases and costs. Having all the information in one central database would allow the diverse facilities to use the database.
