Knowledge management system is very advantageous for the organizations in sharing of information about the organization, in keeping down excess of
work, in reducing the effective consumption of time and in codifying the knowledge. With the help of this system, the company can manage needed
documents and share information within different levels (Alavi & Leidner, 2001).

information about the resources of the firm such as human resource, financial resources, details about material, suppliers, vendors, and other tangible
assets and deals with the planning and use of resources used in the business (Chiat & Ching, 2004). ERP solution has an advantage of fast

Databases in My Organization
Abstract
Databases have been in use since the early days of computing programs. An Information Technology services company, such as Getronics, not only
utilizes databases for information and record management, it earns revenue by providing database management services. Getronics uses Microsoft SQL
Server 2000 as its database software. The clients that contract Getronics for Information Technology services rely and depend on the accuracy and
currency of the database information that is stored. Databases will continue to exist and expand as more companies become more of aware of the
importance of record and data management.

An incident management system tracks end user requests, problems, and changes that are recorded by a service desk, or help desk team. The
application relies on over 300 tables that contain individual pieces of information the build an end user's request. Each table is linked by a common,
unique identifier, commonly known as primary key. This unique identifier exists in all tables and links the records together. However, even though the
backend application is complex, to a help desk technician, the information is presented in the incident management system in an organized, presentable
manner. The help desk technician does not have to search the 300 or more tables to locate a specific piece of information.
Another database that is used by Getronics is the human resources database that is linked to the SAP application. This database contains all of
Getronics' employee information including such private details like social security number and mother's maiden name. This database is secured
database that can not be accessed by any employee. In fact, not even the database administrator can see the text that is stored in the records for the
employees. The data is encrypted. Since Human Resource databases typically contain financial and personnel information, it is important that the data
is secured. The encryption provides security for the private and confidential

Database A database is an organised body of related files and or information. It is simply an automated library system an is maintained as an integral
part of most organisations worldwide. A cite on the World Wide Web, the Webopedia Computer Dictionary, refers to the
database as a collection of
information organized and presented to serve a specific purpose. (A telephone book is a common database.) A computerized database is an updated,
organized file of machine readable information that is rapidly searched and retrieved by computer.

Sophisticated languages for managing database systems are called fourth–generation languages, or 4GLs for short.
The information from a database can be presented in a variety of formats. Most DBMSs include a report writer program that enables you to output data
in the form of a report. Many DBMSs also include a graphics component that enables you to output information in the form of graphs and charts.
Migrating from the manual and paper file set up is always an advantage in its own capacity. We shall highlight the major advantages of using a
database or Data Base Management System in an organisation. Using a database will reduce both data redundancy and inconsistency. For larger or
even smaller organisations like a small time starting estate agency, a database will promote sharing of data for example when referring to client files.
Their rent or sales teams can share the information in order to be able to assist their clients better. Standards are enforced, through the use of the data
dictionary or catalogue. Another advantage is that privacy and integrity controls are applicable to groups of users such as passwords and access
controls for security. In–terms of privacy, a selection of authourised users can use the database and with reference to integrity, the database

A new energy is rising within CNS. Over the past year, many members of our administrative computing team have been developing Oracle
applications. It is a new challenge to both CNS and our clients. We journey up the learning curve together and over the trial–and–error hurdles. Each
day offers a new opportunity to understand another concept or process.
Some faculties and departments are already using Oracle applications in their day–to–day operations. As time goes by, more and more information
users will be working with an application based on Oracle database technology. If you get the opportunity to be a member of an application

A field has little meaning unless it is seen within the context of other fields. The postal code T6G 2H1, for example, expresses nothing by itself. To
what person or business does it belong? The postal code field is informative only after it is associated with other data. In Oracle, the fields relating to a
particular person, thing, or event are bundled together to form a single, complete unit of data, called a record (it can also be referred to as a row or an
occurrence). Each record is made up of a number of fields. No two fields in a record can have the same field name.
During an Oracle database design project, the analysis of your business needs identifies all the fields or attributes of interest. If your business needs
change over time, you define any additional fields or change the definition of existing fields.
Oracle Tables
Oracle stores records relating to each other in a table. For example, all the records for employees of a company would be stored by Oracle in one
table, the employee table. A table is easily visualized as a tabular arrangement of data, not unlike a spreadsheet, consisting of vertical columns and
horizontal rows.

Database Research Essay
Introduction In order to obtain peer reviewed research articles related to the impact of the psychological contract on job satisfaction in community
mental health care workers it is important to review research that has been completed in a variety of researchers and in different settings. The
databases that were selected to locate peer reviewed articles for this paper where Academic Search Complete and ProQuest Psychology. Tutorials
were available for each of these databases and ProQuest was used to learn how to navigate through the data base since it was not a familiar data base
to this author. ProQuest is a database that offers a variety of options in completing a search. A researcher can select to do a basic search, an...show more

Results of the analysis were similar to other research findings in other studies in different settings and although measures can be developed for
different levels of employees, the psychological contract is different to each employee in relation to how the employee perceives his job and develops
his own psychological contract (Cable, 2010). Limitations that could be identified in the study were the small sample size that included only
managers, was conducted only in New Zealand and therefore may not be able to be generalized to other countries (Cable, 2010). Results and
discussion suggests that future research could expand the understanding on how the fulfillment of the psychological contract could impact an
individual employee's attitudes and behaviors (Cable, 2010). After a search in ProQuest the article Transformational Leadership and Public Service
Motivation: Driving Individual and Organizational Performance, was selected for review to determine if the content is relevant to research topic. An
empirical research method in which the authors reviewed a vast amount of past research was used to explore ways in which managers can use positive
motivation to improve public service employee and organizational performance as well as give recommendations to assist managers to implement
motivational values in a variety of management settings (Paarlberg, L., Lavigna, B.,

For example, if some on had to listen to a song on a tape they would have to rewind it to the exact spot of the tape to get the information that they
needed.
That's is what caused the invention of file systems. The file system closely resembled a filing cabinet. Just like a filing cabinet Information was
stored in files or directories. These folders could be placed in other folders thus creating hierarchy i.e. it eradicated a single directory or folder, and
this was the basis for the file hierarchy system. The reason File Systems are necessary is because it ensures reliability in data storage and it also
manages access and retrieving data much easier and quicker. But this wasn't the end of databases, new technology kept coming into the market.
As computers grew in speed and capability the same had to be with information storage. In the 1960s, the term database management was coined in to
existence. That's when two standards emerged, the hierarchical model was by IBM's Information Management System and the other was the Network
model by Charles Bachman IDS (Integrated Data Store). With the introduction of these two models indicated how serious business data was becoming
to the world.
Then came relational database, Edgar Codd, who worked for the IBM's San Jose Research Laboratory came up with a revolutionary database that
would change the way information was stored. He used a "A Relational Model of Data for Large

Databases have been around long before the computer first utilized them, but they became a necessity as the industry has been using them now for
over 40 years. Everything is a database now, your inventory, your class schedule, your closet, it is all a possible database. Arora and Gupta state,
"Stand alone applications have been replaced with web–based applications, dedicated servers with multiple servers dedicated storage with network
storage" (Arora and Gupta 2012). There have been several movements to try and change the database environment, however attempts to replace the
relational database with the object–oriented database never came to popularity and relational databases popularity remains high today. However, a new

Cloud computing has really shifted the whole landscape of how companies do their databases now, and with this has brought the concept of big data.
According to google big data is defined as, "Extremely large data sets that may be analyzed computationally to reveal patterns, trends, and associations,
especially relating to human behavior and interactions". Big data has really taken off with the use of cloud computing. Though they sound the same,
the main difference between cloud computing and big data is the cloud is the actual infrastructure while big data is the actual content you will see in
the database. Today's industry is built off information, the more information a person can get to know about you, the more they can use to their
advantage. A good example of this is the shirts you buy off an online retailer. If you have information and trends that show you may get suggestions
similar to that brand with recommendations or even get promotional coupons depending on how much information you have given to this company
about yourself. These companies with their powerful databases can look at an individual user making this concept very powerful in today's market.
According to Ularu, Puican, Apostu, and Valicanu (2012), "IBM's view Big Data has four aspects: Volume... Velocity... Variety... Veracity." These are
all determined from the how big the size and
