Heterogeneity And Interoperability Of The Digital Library

Heterogeneity And Interoperability Of The Digital Library
Digital library
The Digital Library Federation (2002) define them as organizations that provide the resources including the specialised staff, to select, structure, offer
intellectual access to, interpret, distribute, preserved the integrity of, and ensure the persistence over time of collection of digital work so that they
are readily available for use by a defined community or set of community. Information is a basic human need, and civilization advances when people
are able to apply the right information at the right time (Fox and Marchionini, 1998). Today, digital libraries act as an effective device in the progress
of human civilization, it also should enable any citizen to access all human knowledge anytime and anywhere, in an efficient ... Show more content on

Interoperability means the degree to which two products, programs and many more that can be used together or the quality of being able to be used
together. While heterogeneity consisting of parts or things that are very different from each other. Most oflibrary users depend on library services in
getting information needed. In this situation, when digital libraries want to provide information, it is important to have a good relationship between
heterogeneity and interoperability. To achieve a good interoperability, the exchange information in heterogeneity should covers all types of syntactic
structural, semantic diversities among system to modeling information.
Besides that, it should be consistent between the use of the information as intended by its originator and the intended exploitation of it by the
recipient. This thing need to be considerate to fulfill the need of library users that comes from many different background. Information providers
which is digital libraries should make a data or information about their collections available for harvesting. This data will be use by service provider

The Importance Of Information On The Collection Of Data
Collection of data first
There are many reasons to be excited and not worried about the collection of user data from websites and mobile applications. Since the beginning of
2017, there has been an increase in the number of websites participating in the collection of user data, this is called metadata. Metadata is extra
information about data collected via website or application visits, it is a description of data allowing businesses and developers to better understand,
use and develop their customer experience. Without the collection of data of website or application visits, businesses and developers would be without
feedback about the characteristics of their customers limiting the amount of improvements possible for the service they ... Show more content on

Some may argue that metadata collection may become uncontrollable although, the collection of personal data can easily be monitored to prevent
misuse. Internet providers and the government can easily monitor and prevent businesses and developers from collecting irrelevant personal data. In
fact government agencies in Australia are already accessing metadata according to Sydney Morning Herald "Agencies accessed metadata 330,640
times in 2012–13 – an 11 per cent increase in a year and a jump of 31 per cent over two years" (Grubb & Massola, 2014).
Product relevant personal data should definitely be allowed for collection via businesses as product relevant personal data provides business with vital
information about their online customer bases and current products. For example, a clothing store that collects relevant personal data may be
collecting the age and gender of their website visitors. If the data collected from the clothing store showed an increase in 30 to 40–year–old female
visitors the data could influence the businesses decisions, resulting in the business stocking more of female clothing for 30 to 40 year old females.
Through information like this businesses and developers can develop a long–term and short–term vison easily using metadata

Publishing Metadata Facilitates Data Sharing
2.7.4 Spatial Metadata Publication
Publishing metadata facilitates data sharing. Sharing data between organisations stimulates cooperation and a coordinated, integrated approach to
spatially related policy issues (Land Information Council of Jamaica 2008).
Metadata records are usually published through catalogue systems, sometimes called directories or registries (Nogueras–Iso et al. 2005). Also,
Catalogue Services for the Web (CSW) open standard by the Open Geospatial Consortium (OGC) supports the ability to publish and search collections
of metadata for data, services, and related information objects.
Spatial Metadata Discovery
Because of spatial metadata's small size compared to the data it describes, metadata is more easily shareable (ESRI 2002b) and is considered as the
surrogate of spatial datasets which is referenced to its related spatial dataset. Hence, in a networked environment, such spatial surrogates are
discovered by the end users seeking required spatial datasets, through catalogue systems, Web services and user interfaces. The user interface usually
supports making a variety of queries (via basic and advanced search) on spatial metadata records to retrieve the characteristics of the most appropriate
datasets for the end users..
Once the results of metadata discovery are presented to the end users, the metadata records need to be retrieved and accessed by them. The next
section gives a brief overview of the retrieval and access step of the

Is Data And Metadata Sharing?
Data and metadata sharing is are crucial for both research and educational data. Educational data, in particular student–success initiatives, both funded
and unfunded, often operate in isolation with little interaction outside of the department or college, and they are rarely connected to broader
institutional efforts. Lack of knowledge sharing concerning initiative effectiveness and lessons learned makes it difficult to learn about promising and
best practices and institutionalize them. This paper presents a framework for sharing metadata, enumerates various considerations of technologies and
infrastructure that needs to be accounted for while building such a framework along with a thorough review of the related technologies and ... Show

The reuse promptsof resources for requires sharing of data that is trustworthy. Some of Tthe advantages of data sharing include: a) reanalysis of data
helps verify results data; b) different interpretations or approaches to existing data contribute to scientific progress, especially in an interdisciplinary
setting; c) well–managed, long term, preservation helps retain data integrity; d) when data is available, (re–)collection of data is minimized. Thus
optimizing use of resources; e) data availability provides safeguards against misconduct related to data fabrication and falsification; and f)
replication studies serve as training tools for new generation of researchers (Tenopir et al., 2011) are well documented [1]. There are several inherent
problems to reap the benefits of data sharing. One of these problems is Identifying identifying and integrating related data from disparate sources is
one of the major associated problems with data sharing as data is usually stored on disparate sources. This is compounded by failure to develop and
maintain clear, well–annotated research datasets (metadata), which in turn results in loss of access and understanding of the original dataset overtime.
Metadata helps users decide on the credibility and trustworthiness of data it is associated with. According to data sharing practices and perceptions

Theodore Roosevelt And The Roosevelt Center
Theodore Roosevelt during his life would spend time in North Dakota to hunt buffalo and settled in a ranch there for some years as he found a
renowned interest in the area he called his "second home". In 2005, Dickinson State University (DSU) began to explore the legacy of the 26th
President as a tribute to his historical legacy and admiration to the territory that the university resides today. As a result theTheodore Roosevelt Center
was founded in 2007 at the university. In essence the Theodore Roosevelt Center was founded to manage Roosevelt's archives as like many prior
presidents, he did not have an established presidential library. Many of his papers were scattered in archives around the country including the Library
of Congress, Harvard University, six national parks, and in smaller collections at numerous other repositories. In 2008, DSU began a partnership with
the Library of Congress to digitize the Library's vast holdings related to Theodore Roosevelt, with the intent to make them freely available online. Its
broad audience scope is to attract everyone from scholars and schoolchildren, enthusiasts and interested citizens and to provide well organized high
quality reference material to enthusiastic seekers of our 16th president. The physical library is expected to open in 2019 but is available online.
Recognizing the significance of the contributions being made by Dickinson State University in preserving and promoting Roosevelt's legacy, in the

SCADA Policy Controls
The term cybersecurity encompasses a vast amount of topics and imperative security issues. Perhaps the most difficult issue with cybersecurity is
implementing policy controls that are applicable and effective among a variety of individuals, companies and governments. Policy controls are needed
to reduce cybercrime, cyber terrorism, threats to SCADA systems and zero day exploits. The most controversial topic that policy controls need to
address is Meta data collection and its terms of usage by not only the government but the private sector as well. Additionally, governmentsecurity

It is for these reasons that the collection, retention, and sharing of that data must be regulated. Government regulations could help protect consumers
in a variety of ways. The first policy suggestion would be to provide users with increased control over their personal data. There are a few key
strategies that can be used to increase consumer privacy. The first one is the "opt in" rule, which means collection of customer data does not happen by
default, and can only happen after a consumer has given explicit consent. The "opt out" rule is the collection of consumer data occurs by default and it
is up to the consumer to choose to have that collection stopped. A final strategy is the anonymizer, which allows consumers to use a businesses'
services while being logged in under an anonymous log in (Newman, 2014). Additionally, government policy and regulation should be aimed at
increasing the competition in the marketplace, hence the term marketplace competition, as means of ensuring that there are multiple businesses that are
able to offer varying degrees of privacy protection to consumers (Newman, 2014). The government can also regulate private business collection and use

Unit 1.4 Research
1.4 Research Issues and Challenges Spatial data is a costly resource to generate and maintain, spatial data consumers have been unable to accurately
and conveniently link with other spatial data users to share and discover useful and relevant data. There is problem of insufficient and inappropriate
metadata available for the clearinghouse, metadata problems impact on effective spatial data use. The following are examples of issues associated with
spatial metadata: Metadata records are absent or incomplete for some datasets. In such cases, if the contents or structure of the acquired data is difficult
to understand, the user could be limited in effective use of the data. For instance, the metadata may contain missing elements such as: spatial reference
information, scale, data currency and data originator contact details. If such relevant information like spatial reference is missing, this could delay or
prevent further application of the data [27].... Show more content on Helpwriting.net ...
Metadata should be as current as the data. In other words, when data is created or edited, its metadata should .immediately be created or updated to
reflect data changes. However, creating and updating metadata requires a substantial quantity of work and time. For this reason, data holdings are
largely left unchecked for their appropriate age and structure to verify which data should be maintained, updated or deleted. Therefore, institutional
spatial data memory could be lost through inappropriate storage of metadata records. Furthermore, outdated metadata could misinform and confuse
users about the data

fact, even many technologically inclined people may not have a sound idea of what exactly metadata means. Although many people don't recognize the

So I will use an example to further clarify. The card catalog system that has been used in libraries for years is an example of a standardized system of
metadata. Certain requirements are demanded for each book and this data is stored on a card that makes finding and accessing the needed book
efficient. This is metadata in its oldest and purest form.
Metadata Standards
Metadata standards are even more important in regards to digital information. Metadata used to classify information stored online crosses many
different hardware and software platforms, and because of the vast amounts of information there is a need for it to be sorted by machine rather than
by human, as in the card catalog system. These parameters call for a standard that is both visible to the user and readable by a machine. This is what
many of the metadata standards in effect today try to accomplish.
Metadata standards can be looked at from two different extremes, the minimalist view or the structuralist view. The minimalist view is to have only a
small number of requirements that are easily input by inexperienced users. This allows for most information to be at least somewhat classified and
easily found. From the structuralist view strict requirements should be imposed so as to keep well documented information well defined and found
with great accuracy.5
A prime example of a minimalist metadata structure is The Dublin Core Metadata Initiative. In their own words, "The

Imagine being in a room with 10 people talking to you. Would you be able to understand the conversations? It would be hard to concentrate on any
one person's conversation, but you could probably do it. Now, imagine being at the Superdome with 70,000 people talking to you. Would you be
able to understand any of the conversations? You probably could not understand any one person for a length of time, but again you might pick out
some of the words. Well, what if the scenario was 7 billion people speaking 6 thousand languages at an auctioneer's pace on the topic of their

Types of spatial metadata
Spatial information is necessary to make sound decisions at the local, regional and global levels. Therefore, the amount of spatial datasets being
created and exchanged between organisations or people is increasing considerably. According to a released study by for the period of 2004–2010, the
overall growth of geospatial industry has increased by 11% in the areas of data, software and services. The spatial metadata in terms of collection can
be divided into two groups:
Inherent Metadata – information that can be derived through the computer analysis of the contents of any collection, such as: temporal coverage (e.g.
visualisation of the time periods covered or publication dates); types of items and the number of each; formats of items and the number of each;
example of full metadata content; geospatial and image collections; number of thumbnail/browse images available; types of geospatial footprints (e.g.
points, bounding boxes); geographic coverage of the information (map visualisation based on latitude and longitude coordinates of items in the
collection)
Contextual Metadata – information supplied by the collection provider or collection maintainer that cannot otherwise be derived from the collection's
contents, such as: title, responsible party, scope and purpose, type of collection (digital items, offline items, gazetteer, etc.), date (creation or latest
update), update frequency, metadata schema(s), terms and conditions of use for

National Security Agency Surveillance
In January of 2014, news agencies reported on the National Security Agency's (NSA) use of "leaky" mobile phone applications to obtain private user
information. The United States government has admitted to spying on its citizens, but claims that doing so is the best way to protect the U.S. from
foreign threats. Certain smartphone applications, such as the popular Angry Birds game, inadvertently transmit personal user information, such as age,
gender, ethnicity, marital status and current location, collectively known as the user's metadata, across the internet[1]. As part of their world–wide
telecommunications surveillance for terrorism or other criminal activity, the NSA exploits these security holes in smartphone applications, by collecting
and storing user data. While many users are unaware of the information leaks in their mobile applications, most people would certainly prefer to keep
such information private [2]. Smartphones know almost everything about who we are, what we do, and where we go, but how much of that
information does the government have the right to know and possess? Is it ethical for the United States government to collect and track the cell phone
data of its citizens in the name of national defense, or does that violate the citizens' right to personal privacy? NSA surveillance of private user data of
U.S. citizens is the best method of protection against terrorism and is also legal under the Constitution. By examining these two components, it is plain

Conclusion
This research has focused on the disciplinary powers relative to the use of panopticon surveillance through CCTV and metadata technologies.
Discipline amongst the masses has been of interest for governments since early societal developments. With the growth of technology, we may argue
that the disciplinary society has gone too far with the development of new technologies which is now infringing on our personal privacy. These
technologies have panoptic properties since it is the relatively few, watching the many. The first technology examined is the use of CCTV cameras.
CCTV cameras utilize both covert and overt operations of vertical surveillance that contribute to the panoptical gaze when we leave the comfort of
our private space. CCTV cameras have been justified within society since there is an increasing need for them in solving crimes, and for internal
business use. We found that the best way to enforce discipline among the usage of CCTV cameras is within the strategic placement of the device along

Setting basic information in the hands of a cloud supplier ought to accompany the assurance of security and accessibility for information very still, in
movement, and being used. A few choices exist for capacity administrations, while information secrecy answers for the database as an administration
standard are still youthful. We propose a novel construction modeling that coordinates clouddatabase administrations with information secrecy and the
likelihood of executing simultaneous operations on scrambled information. This is th first arrangement supporting geologically disseminated customers
to join straightforwardly to a scrambled cloud database, and to execute simultaneous and autonomous operations including those adjusting the database
structure. The proposed building design has the further favorable position of wiping out middle of the road intermediaries that cutoff the versatility,
accessibility, and adaptability properties that are inborn in cloud–based arrangements. The viability of the proposed construction modeling is assessed
through hypothetical examinations and broad test results in view of a model usage subject to the TPC–C standard benchmark for diverse quantities of
customers and system latencies.

Importance and Need of ETL
ETL Process
Extraction, Transformation, and Loading processes are responsible for the operations taking place in the back stage of a data warehouse architecture. In
a broader aspect, initially the data is extracted from the source data stores which could be On–Line Transaction Processing or Legacy system, files of
any formats, web pages or any other documents like spreadsheets or text documents. In this step, only the data which is different from the previous
execution of ETL process (newly inserted, updated) gets extracted from the sources. Next, the extracted data is sent to Data Staging Area where the
data is transformed and cleaned. Finally, the data is loaded to the central data warehouse and all its counterparts e.g., data marts and views. (Kabiri &
Chiadmi 2013, p.1)
Need of ETL Process
ETL is a critical component in DW environment. Indeed, it is widely recognized that building ETL processes, during DW project, are expensive
regarding time and money. ETL consume up to 70% of resources. Interestingly reports and analyses a set of studies proving this fact. In other side, it
is well known too, that the accuracy and the correctness of data, which are parts of ETL responsibility, are key factors of the success or failure of DW
projects. (Kabiri & Chiadmi 2013, p.1)

Data Retention In Australia
Governments have for centuries attempted to restrict the privacy of their citizens. For some time now this has also included efforts to regulate citizens'
communications data by means of collecting and storing information gathered by providers of communication services. These efforts are referred to as
data retention measures and would grant law enforcement agencies unlimited access to this data (Clarke, 2014).
Early this year (2015), the Australian Government amended its Telecommunications (Interception and Access) Act in terms of Data Retention,
commonly referred to as 'metadata'. The term metadata has no formal definition in the Act but has been described as machine–produced data, expressed
in terms of data and content (ABC, 2015; Clarke, ... Show more content on Helpwriting.net ...
The retention of data will indeed make contact with sources challenging, and even frustrating. However, when has investigative journalism ever been
easy? Take Bob Woodward and Carl Bernstein back in 1972 for example, who relied on unnamed confidential source 'Deep Throat' for leads on the
Watergate scandal involving then President Nixon. Investigative journalism has always been discrete and conducted in a secretive fashion, so why
should metadata retention stop or see a decline in the work of undercover reporters? It most certainly should not. The media play an essential role in
democracy. It is now more than ever, the time for investigative journalists to overcome these new obstacles and continue seeking truths and discovering
secrets, even under the watch of 'Big

Metadata Quality: Importance, Standards, Assessment, and Challenges
Metadata is a vital aspect of information organization today. Without quality metadata, the worth of collections is diminished and the ability for records
to be used is non–existent (Park & Tosaka, 2010). Thus, metadata is the cornerstone oflibrary systems, and it is imperative for academic research.
Further, if standards for metadata are not established, there is no agreed upon quality, making interoperability of records impossible (Park, 2009).
Despite the obvious importance of quality metadata, little work has been done to develop a standard or best practice guideline. The National
Information Standards Organization (NISO) has established six principles that make up ... Show more content on Helpwriting.net ...
Thus, metadata quality cannot be assessed by a full MARC record. Instead, catalogers must use other assessment methods. For instance, Bruce and
Hillman assess quality metadata through a seven layer framework: completeness, accuracy, provenance, conformance to expectations, logical
consistency and coherence, timeliness, and accessibility (David & Thomas, 2015). A different proposal from Stvilia and Gasser (2008) propose a
system of assessment that analyzes metadata records both empirically and analytically. This allows records to have sound metadata quality, but does
not require a quality above what is functional for a record. Zschocke and Beniest (2011) advocate a quality assurance method that utilizes peer–review
and automation to check metadata while it is being created. One of the leading tools used to evaluate metadata currently is its usefulness to end–users.
If end–users are supplied with numerous application of records, then the quality of the metadata is higher than a record whose applications for an
end–user are minute (Park & Tosaka, 2010). The study of Park and Tosaka (2010) reveals that the most commonly used assessment of metadata is the
application of accuracy and consistency. If a record is accurate and consistent, it is valued over a complete record because accuracy and consistency
can be checked and assessed on all record types, unlike other forms of assessment. Intrigued by Tosaka and Park, three researchers

Integrating Data in a Heterogeneous and Real–Time IT Environment
Summary and Evaluation
Technology has changed vastly in the last fifty years. These changes can be seen in many areas such as airline reservation systems, automated teller
machines, mobile phones, the internet, world wide web and sensor networks. These sources generate a lot of data; heterogeneous data means coming
from different sources. Businesses have focused on automating their processes, and they have realized that data integration is becoming complicated.
Thus, it is important to understand how to integrate and analyze data in real–time.

The main goal of this real–time data operation intelligence is to eliminate the data warehousing latencies. By achieving this, the organization can make
better decisions hence able to make more rapid decisions.
The security factor in data warehousing is a main area to focus on. Colin discusses an example of a company that was highly charged due to not using
the fraud detecting system. Thus, the company faced a $45 million fraud because of poor security. To clarify, two people took $45 Million from an
ATM Scheme; they used two card numbers to steal the money. However, the banks didn't detect the fraud because their data integration system was
inefficient.
Operational intelligence workflow is also discussed in detail with its 3 types of environments. There are three types of environment; the first one is data
warehouse environment, where the data aren't changing. This is where the data is analyzed because it is at rest. The other two are operating systems
and real–time analysis platforms, where we can make models, analyze data, and make the analysis. The Analytics and alerts along with the
recommendations are shaped by analyzing Enterprise Data warehouses. Operational dashboard shows what is going on with our business and what
changes we should make. This output is sent to the users via nearby RT operational dashboards.
Colin lists four options for data integration. There are four approaches of OI; the first one is Enterprise DW which has a

have enough metadata, you don't really need content." Metadata is a data that record people's life, but however, it cannot record people's life. Inside
of people's brains, there are recorders that are called memories, every valuable movements in in them. But for metadata is just a data. I disagree with

As life goes on, things get more complicated. People are growing up, they are no longer children, but adults who face reality. Real life is nothing
like fairy tales. Problems are not being easily solved and confusions are everywhere. There is never a long period of rest and peace. People should
always be aware of everything preventing them to live an easy life. Life could not be record by metadata, because it is too long and too complicated.
Life is not just a piece of paper that list everything about people who signed up for it. It's just like a map that tells people where they were in a certain
age. When people get old, they will not care about what they achieved. They will only care about the beautiful memories they have. It is the most
precious thing they have. It would be hard to live in a life with only facts and without feelings. Because facts do not mean anything. The experiences
and feelings created facts. Without humanity, metadata means nothing but bunch of

How To Publish Metadata Endpoints For A WCF Service?
To publish metadata endpoints for a WCF service, you first must add the Service
Metadata Behavior service behavior to the service. Adding a system service model description service metadata behavior instance allows your service
to expose metadata endpoints. Once you add the system service model description service metadata behavior service behavior, you can then expose
metadata endpoints that support the
MEX protocol or that respond to HTTP/GET requests. The system service model description service metadata behavior uses a Wsdl Exporter to export
metadata for all service endpoints in your service. For more information about exporting metadata from a service, see exporting and importing metadata.
The system service model description service ... Show more content on Helpwriting.net ...
The policy version property can also be set to
Policy12. When set to Policy15 the metadata exporter generates policy information with the metadata that" conforms to WS–Policy 1.5. When set to
Policy12 the metadata exporter generates policy information that conforms to
WS–Policy 1.2.
6. Add the service metadata behavior instance to the service host's behaviors collection. 7. Add the metadata exchange endpoint to the service host.
8. Add an application endpoint to the service host.
9. Open the service host and wait for incoming calls. When the user presses
ENTER, close the service host.
10. Build and run the console application.
Use Internet Explorer to browse to the base address of the service
(http://localhost:8001/MetadataSample in this sample) and verify that the metadata publishing is turned on. You should see a Web page displayed that
says "Simple
Service" at the top and immediately below "You have created a service." If not, a message at the top of the resulting page displays: "Metadata
publishing for this service is currently disabled." (WCF)
Retrieving Metadata
You can use Svcutil.exe to download metadata from running services and to save the metadata to local files. For HTTP and HTTPS URL schemes,
Svcutil.exe attempts to retrieve metadata using WS–Metadata Exchange and XML web service discovery. For all other URL schemes, Svcutil.exe uses
only WS–Metadata Exchange.
By default, Svcutil.exe uses the bindings defined in

Security Issues Dealing With Metadata
Security Issues Dealing with Metadata Most companies and government agencies are collecting and storing massive amounts of information dealing
with all aspects of everyday life. This information ranges from an individual's movements, captured on a city's traffic cams, to details of what someone
purchased at the local grocery store. Most of the information is random and anonymous however, there may be large amounts of personally identifiable
information (PII) such as email addresses, birth dates, and bank card numbers as well (Damiani, Ardagna, Zavatarelli, Rekleitis, & Marinos, 2016). The
type and quality of information as well as the natures of the organizations collecting makes this "Metadata" a desirable target for cybercriminals. The ...

The second security issue involves dishonest workers. The collection, storage, and processing of petabytes of data requires countless workers of
varying skill levels and backgrounds. It is a formidable task to investigate and certify the integrity of each of these workers and the difficulty of this
task is compounded by the use of external contractors and service providers. The information they are working with, adds to the problem. Although
most of it is benign and mundane, it can still provide valuable marketing data to competitors (Parms, 2015). If, on the other hand, embarrassing personal
information could be linked to someone famous, it could be quite profitable to the dishonest employee who leaks it. The third security issue involves
poorly trained or novice employees. These employees are more likely to fall victim to social engineering or phishing schemes that can compromise your
network. They are also more likely to make unintentionally make mistakes that can delete or corrupt the data stored on your network (Damiani,
Ardagna, Zavatarelli, Rekleitis, & Marinos, 2016). The final security issue concerns an outside attack. These attacks can be used to disrupt the business
or to penetrate the network and steal information. Although the anonymous information is

NSA Spying
NSA Spying – What is Metadata and What Does the Law Say? Technology is in everything we do from using our home refrigerator, washer, cellular
device, automobile, and or computer systems. When using certain devices you pass information to others pertaining to personal and private
information. This information or metadata could be a bank account or credit card number, pin, and or password that we unconsciously share. We
randomly give away this information at a dentist or doctor's office, the local liquor store, or when we visit social media sites like Instagram,
Facebook, Yahoo, and or Google. This information is all collected, stored, and tracked by big brother, and what are they doing with it, is the metadata
being secured, American's may never know. Disturbingly the National Security Agency (NSA) has been collecting metadata on Americans personal
telephones and electronics devices for several years. This collection was happening before the NSA Analyst Edward Snowden leaked these facts to the
world in late 2013. The NSA was formed in the 1950's, and during this time frame the NSA disseminated intelligence information from electronic
signals for foreign and counter intelligence purposes, which supported the American military needs. Currently the NSA has refocused their spying
tactics to technology driven devices. The NSA has an extensive "telephone–metadata program, since 2001, and they collect phone records of virtually
all Americans" (Lizza, 2013). Email and Social

Data About Data And Information About Information
The term metadata first used in 1969 is called 'data about data' or 'information about information'. The term 'meta' derives from the Greek word
denoting a nature of a 'higher order' or more 'fundamental kind' , or 'above', 'beyond', and 'of something in a different context' , metadata is data
associated with objects which relieves their potential users of having to have full advance knowledge of their existence or characteristics. It helps in
finding data and tells how to interpret and use data. Metadata gives descriptive information about the producer, content , quality, condition and other
characteristics of a dataset. Metadata ensures use of right data for right purpose, Metadata assigns quality and defines limitation, improves the
appropriate use of data, provides entity and attribute information about the following: Originator

You have to understand that metadata is the billboard on the side of the road that announces what is coming up ahead. It tells the approaching visitors
not only you have a website or blog, but also what they will find on your site.
Metadata has two principal functions.
1– To help visitors scan the page and decide if they want to visit your site.
2– To help search engines find and advertise the page.
This is so important for any website or business that want people to read, watch and share their content.
That is the reason we want to give you some very important guidelines to utilize on your site.
If you did pass the test and are satisfy with your metadata, well, good for you keep up the good work.
However, if you did not pass the test here's how you can start.
How can metadata make your content shareable?
Metadata have three fundamental components:
1–Page Title (or Title tag),
2–Description (or Meta Description)
3–Keywords.
Some of them are invisible and resides in the codes of your web pages.
Keywords, for example, can only be seen is by viewing the page source and looking at the tag, it will look like this:

When sharing a web page on social media network, you will see a preview of the content, it normally displays a picture, a title, source name and a
short description. The preview reflects exactly the quality of the metadata of that site, and the good news is you are the maker and have absolute

Demographics And Its Impact On Health And Health
In my research, I discovered that population trends will dramatically impact healthcare. Simply put the more people who exists the more healthcare
that is required. Population is not the only factor and other sub factors of population such as age, race, and ethnicity or demographics and they also
have an impact on Healthcare. For example, the population of people in the U.S. over the age of 65 in 1950 was only 8.1% of the total population. The
trend of that number is expected to rise to 20.2% by 2050. Geographic trends can assist healthcare professionals where to focus their educational efforts
in terms of healthcare availability. Psychographics' examines the consumer or the factors that motive them such as values, attitudes, beliefs, motions,
interests, and personalities.
Demographic trends can be used to target specific gender and ethnic groups from a healthcare perspective. An example of this targeted healthcare is
research showed that males, both non–Hispanic and Hispanic, in the Michigan area where "disproportionately affected by cancer" (Kodjebacheva,
Blankenship, Hayman Jr, & Parker, 2016). The application of this is by knowing this data and data similar to it, we will be able to have focused
HealthCare to the demographics that statistically need it more than others.
The study of Geographic trends will allow us to better understand physically where healthcare resources are lacking compared to other typically
developed areas. An example of application here is a study

Austin, Scott E. Breach, and Gurindar S. Sohi [1]. The idea here is to augment the pointer representation in memory with the bounds of the
pointer's target. Spatial safety is enforced by checking these bounds whenever a pointer is dereferenced. These fat pointers consist of the
following parameters, value: The value of the safe pointer; it may contain any expressible address., base and size: The base address of the referent
and its size in bytes, storageClass: The storage class of the allocation, either Heap, Local, or Global., capability: When dynamic variables are
created, either through explicit storage allocation (e.g., calls to malloc()) or through procedure invocations (i.e., a procedure call creates the local
variables in the stack frame of the procedure), a unique capability is issued to that storage allocation. The value attribute is the only safe pointer
member that can be manipulated by the program source; all other members are inaccessible. base and size are the spatial attributes. storageClass and
capability are the temporal attributes. 1.2CCured CCured is a program transformation system that adds memory safety guarantees to C programs. It
was proposed by George C. Necula, Jeremy Condit, Matthew Harren, Scott Mcpeak, and Westley Weimer[2]. This approach classifies pointers as

The prescriptions filled usage will provide an actual fact of what medications is being sold, the dally order filled by state will provide what
location is getting the most business, prescriptions filled by year will provide the profits or losses of revenue in the business, online orders will

in to fill an order. All the data for the information needed is related and will be grouped into one data structure or one relational table.

Business Intelligence and Technology
Introduction
In modern business, vast amounts of data are accumulated, which makes the decision–making process complicated. It is a major mutual concern for all
business and IT sector companies to change the existing situation of "mass data, poor knowledge" and support better business decision–making and
help enterprises increase profits and market share. Business intelligence technologies have emerged at such challenging times. Business today has
compelled the enterprises to run different but coexisting information systems.
ETL plays an important role in BI project today. ETL stands for extraction, transformation and loading.
ETL is a process that involves the following tasks: Extracting data from source operational or archive systems which are the primary source of data for
the data warehouse; transforming the data – which may involve cleaning, filtering, validating and applying business rules; loading the data into a data
warehouse or any other database or application that houses data.
ETL Tools provide facility to extract data from different non–coherent systems, transform (cleanse & merge it) and load into target systems. The main
goal of maintaining an ETL process in an organization is to migrate and transform data from the source OLTP systems to feed a data warehouse and
form data marts. ETL process is the basis of BI and it is a prime decisive factor for success or failure of BI.
Today, the organization has a wide variety of ETL tools to choose from market.

Types Of Simulation Software, And Investigating Software...
There are many types of simulation software, and investigating software component metadata for all of them is infeasible. The scope of this research is
restricted to one important class of simulation software, the area of semi–automated forces (SAF) systems. As Petty describes in [14], semi–automated
forces (SAF) systems are computer software systems to generate and control autonomous entities (such as tanks, soldiers, or aircraft) in a simulation
using a combination of behavior generation algorithms and human operator commands. The SAF entities exist in a battlefield that is a simulated subset
of the real world, so the physical events and phenomena on the battlefield must be modeled. SAF–controlled entities should obey the laws of physics.
The accuracy of the SAF physics models is important to the utility of the simulation. Exactly how accurate those models must be, depends on how the
system will be used. It is not uncommon when the real time performance of the simulation is more important than high accuracy, to have high fidelity
models replaced with lower fidelity models based on look–up tables. Figure 1.1 A screenshot from ModSAF, a SAF system. An important example of
semi–automated forces is One Semi–Automated Forces (OneSAF). In [15] Parsons states that OneSAF is the U. S. Army's newest constructive
battlefield simulation and SAF system. OneSAF is intended to replace a number of legacy entity–based simulations and to serve a range of applications

electronic devices against us. This precedent was started in 1992 with the DEA collecting the metadata from all US calls to countries linked to drug

The answer is yes, it is possible to maintain a modicum of privacy on the internet and cryptography is the mechanism to do so. Cryptography,
however, has a bit of a dilemma. How is it possible to send your cryptographic key over an insecure medium, such as the internet, without it being
intercepted. Thanks to the work of Diffie and Hellman we now have a way to exchange cryptographic keys with an eavesdropping third party without
said third party knowing the key (Hoffstein, Pipher, Silverman 65). To explain how the Diffie–Hellman key exchange works I first have to establish a
cast of characters, Joseph, NSA, and Thomas. When Joseph and Thomas want to exchange cryptographic keys over the internet without the NSA
knowing what it is, they must agree on a prime number represented by p, and a number greater than zero represented by g (Hoffstein, Pipher,
Silverman 66). Numbers p and g are public knowledge and the NSA has. Thomas and Joseph then select numbers that they don't reveal. For Thomas
the secret number is represented by a, and for Joseph the secret number is represented by b. To generate the key Joseph plugs his values into the
equation A= ga(mod p) and thomas plugs his values into the equation B= gb(mod p). Thomas and Joseph exchange these values, again with the NSA
intercepting, and do some further calculation to make the key. Thomas takes Joseph's value and
