Cis 109 Assignment 3

Data objects can model relational data or advanced data types such as graphics, movies, and audio. Smalltalk, C++, Java, and others are objects used in object-oriented data. The object-relational is a combination of relational and object-oriented databases. Traditional and advanced data types can be used to construct database management systems. These systems can connect to a company’s website and update records as needed. Database Approach The main purpose of a database is data storage that can be stored and retrieved when needed. A popular common language called structured query language (SQL) is used to store and retrieve data in relational database. This language enables the systems to run a report or modify data or remove the data from the database. A database management system (DBMS) controls all aspects of a database, this is not limited to the creation, maintenance, and use of database. The DBMS ensures proper applications are able to access the database. An important purpose of a DBMS is to maintain the data definitions (data dictionary) for all the data elements in the database. It also enforces data integrity and security measures. Data Models Data models provide a contextual framework and graphical representation that aid in the definition of data elements. In a relational database, the data model lays the foundation for the database and identifies important entities,

very important is the elimination of duplicate data, also known as redundant data, which not only

1. The cartoon is of a Mongolian man's head, with eight tentacles spreading out. Each tentacle contains unwanted things that the illustrator thinks the Mongolians will take with them into Australia, should there be an influx of immigrants. The head if the man is drawn in a menacing manner, with an unfriendly scowl and two buck teeth that have a gap the size of another tooth between them. The multiple alleged vices of the Mongolians include: cheap labour, pak ah-pu (a gambling game), immorality, small-pox and typhoid, opium, bribery, fan-tan (another gambling game) and customs robbery. The fact that the man is depicted as an octopus implies that the Mongolians are thought of as slimy, unclean and therefore subordinate and perhaps the fact that the Asians would get a 'hold' on Australia.

The requests below was created 7/10/2015, we needed to have requests enter 2 weeks in advance before demo. Furthermore, we pull the report mid-day last Friday so we did not see the request below. Lastly, the request need to be fully approve by your AD before we can start fulfilling. We went ahead and gather your 3 slims and 3 colonoscopes because your AD reach out to us last Friday. We will try our best to gather your gastroscopes but our record indicated that we only have 2 of the version 1.6 gastroscope at the moment and it is at a demo. Let us know if you have any additional questions.

My first assignment required me to make a plan of my essay, find a topic and create a research question. I struggled to find a subject at first since I didn’t want to use the idea I created in CCT109. I decided to choose something that I’m familiar with which was Facebook. As I was doing research I came up with a proposal which was to discuss the kinds of online relationships explored through Facebook. As well as evaluate the difference between online and face to face relationships. After handing in the assignment, I was able to receive constructive feedback from my TA. He wasn’t able to see a specific topic coming through and suggested to ‘‘redo’’ my research. I recognized my errors because he was able to provide a different opinion on my

In 1994, the New York City Police Department adopted a law enforcement crime fighting strategy known as COMPSTAT (COMPuter STATistics). COMPSTAT uses Geographic Information Systems (GIS) to map the locations of where crimes occur, identify “ hotspots”, and map problem areas. COMPSTAT has amassed a wealth of historical crime data. Mathematicians have designed and developed algorithms that run against the historical data to predict future crimes for police departments. This is known as predictive policing. Predictive policing has led to a drop in burglaries, automobile thefts, and other crimes in some cities.

My thoughts on normalization is that it requires multi-steps to enter the data into tabular format to ensure they are well-organized in a way that is consistent and lacks redundancy as well as prevent unintended or unambiguous results. As stated by Demba (2013) that normalization in relational database design often involves the process of organizing data and dividing the database into two or more tables with defined relationships in order to minimize

Ask probing questions and employ active listening skills to find out what their true needs are.

Normalization gives the equal importance to all the variables in terms of variability. As we selected the correlation matrix in the step 2 in the PCA component analysis, so the data is first normalized. The dataset is normalized by subtracting the

Write clearly and concisely about topics related to cybercrime techniques and response using proper writing mechanics and technical style conventions.

Describe the different levels and types of resources required for producing each deliverable described in the assignment summary.

Another competitor to consider is Stars Campus Solutions. STARS® is a cloud-based campus management system that securely and reliably maintains operational data for colleges and schools. STARS® school information system manages the entire student life cycle from lead to placement. Key school performance data is available at your fingertips! The reliability of the STARS school management system is unparalleled. (Solutions, 2013)

Another difficulty using relations that have redundant information is the problem of update anomalies. These can be classified as Insertion, Deletion or Modification anamolies.

Normalization refers to the focus, concentration and independence of the child, by his own choice. It means the child has acquired the internal freedom to initiate work, be independent, and adhere (by choice) to the rules of the environment.

Standard SQL databases adhere to what are commonly called the “ACID” properties. This means that the database must be atomic, consistent, isolated and durable. Atomic means that each attribute cannot be broken into sub groups. Consistent means that the database displays only the latest data; there are no older versions of data present within the database unless by design. Isolated means that no transactions will interfere with one another; i.e. two concurrent users changing the same data in the database will not end with incorrect results; the transactions will be processed separately. Durable means that once changes have been made they will remain in place and not revert to their prior state (Pritchett, 2008). The ACID properties can be crucial to certain business models; financial transactions might require
