Download Big-Data-NoSQL-MongoDB-1-HW - Dr. Tom Hicks

If this lab is an Individual assignment, you must do all coded programs on your own. You may ask others for help on the language syntax, but you must organize and present your own logical solution to
the problem. No lab is complete until the student submits the signed pledge form associated with that lab. I realize that no coded programs will be graded until I turn in the sign & pledge form associated
with that program; any late penalties will continue to compound until the pledge form is submitted.
If this lab is a team assignment, both team members may share logic as they program side by side on their own computers. Each person must type all of his/her own code as part of the learning process.
Team assignments are never to be "You do this portion and I’ll do that portion" or "You do this lab and I’ll do the next lab".
Some of the lab assignments will have short answer questions. These short answer questions will be spot checked and graded for completion, but not checked for accuracy. Once these labs are graded
and returned, I encourage you to compare answers with another class member who has also had the lab graded and returned.
I/We realize that the penalty for turning in work that is not my own, or assisting others in doing so, can range from an "F" in the class to dismissal from Trinity University. I realize that it is a violation of
academic integrity to share any portion of this lab with any person (outside my 2320 team & professor)!

Big Data
Stop the Presentation! Look up and read about “Big Data”. Start with Wikipedia.
1]
______________________________________________________________ Big data is a term for data sets that
are so L_?_ or complex that traditional data processing applications are inadequate. Challenges include analysis,
capture, data curation, search, sharing, storage, transfer, visualization, querying, updating and information
privacy.
2]
___________________________________________________________________ The term “Big Data” often
refers simply to the use of predictive An_?_ or certain other advanced methods to extract value from data, and
seldom to a particular size of data set. Accuracy in big data may lead to more confident decision making, and
better decisions can result in greater operational efficiency, cost reduction and reduced risk.
3]
___________________________________________________________________ Analysis of the data sets,
extracted from “Big Data”, can find new Correl_?_ to "spot business trends, prevent diseases, combat crime and
so on.
___________________________________________________________________ Data sets are Gro_?_ rapidly
in part because they are increasingly gathered by cheap and numerous information-sensing mobile devices,
aerial (remote sensing), software logs, cameras, microphones, radio-frequency identification (RFID) readers and
wireless sensor networks.
4]
5]
___________________________________________________________________ According to research, the
world's technological per-capita capacity to store information has roughly Do_?_ every 40 months since the
1980s; as of 2012, every day 2.5 Exabytes (2.5×10^18)  2.5 Billion Gigabytes of data are created.
6]
___________________________________________________________________ Relational database
management systems and desktop statistics and visualization packages often have difficulty handling B_?_ D_?_.
The work instead requires "massively parallel software running on tens, hundreds, or even thousands of servers".

_____________{T/F} What is considered "Big Data" varies depending on the capabilities of the users and their
tools, and expanding capabilities make big data a moving target. "For some organizations, facing hundreds of
gigabytes of data for the first time may trigger a need to reconsider data management options. For others, it may
take tens or hundreds of terabytes before data size becomes a significant consideration."
Key-Value NoSQL Databases
Look up and read about “Key-Value Database”. Start with Wikipedia.
1]
___________________________________________________________________ A key-value store, or keyvalue database, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, a
data structure more commonly known today as a D_?_ or hash.
2]
___________________________________________________________________ In key-valued databases,
dictionaries contain a Col_?_ of objects, or records, which in turn have many different fields within them, each
containing data. These records are stored and retrieved using a key that uniquely identifies the record, and is
used to quickly find the data within the database.
3]
___________________________________________________________________ Key-value stores work in a
very different fashion from the better known relational databases (RDB). RDBs pre-define the data structure in the
database as a series of tables containing fields with well-defined data types. Exposing the data types to the
database program allows it to apply a number of optimizations. In contrast, key-value systems treat the data as a
single opaque collection which may have different fields for every Rec_?_. This offers considerable flexibility and
more closely follows modern concepts like object-oriented programming. Because optional values are not
represented by placeholders as in most RDBs, key-value stores often use far less memory to store the same
database, which can lead to large performance gains in certain workloads.
4]
Performance, a lack of standardization and other issues limited key-value systems to niche uses for many years,
but the rapid move to CL_?_ computing after 2010 has led to a renaissance as part of the broader NoSQL
movement. Some graph databases are also key-value stores internally, adding the concept of the relationships
(pointers) between records as a first class data type.
Memcached  Key-Value Store  NoSQL
Look up and read about “Memcached”. Start with Wikipedia. Memcached is a “Key Value Store” NoSQL
Database. It is one of the solutions used to manage Big Data.
1]
___________________________________________________________________ Memcached is a generalpurpose distributed M_?_ C_?_ system. Memcached is often used to speed up dynamic database-driven
websites by caching data and objects in RAM to reduce the number of times an external data source (such as a
database or API) must be read.
2]
___________________________________________________________________ Memcached is Op_?_
So_?_ software, licensed under the Revised BSD license.
3]
_______________________ __________________ _______________________ Memcached runs on L_?_ ,
OS_?_, Microsoft W_?_. It depends on the libevent library.
Big-Data-NoSQL-MongoDB-1-HW.docx

Name _______________________
|4|
4]
__________________________________________________________________ Memcached's APIs provide a
very large H_?_ table distributed across multiple machines. When the table is full, subsequent inserts cause older
data to be purged in least recently order. Applications using Memcached typically layer requests and additions
into RAM before falling back on a slower backing store, such as a database.
5]
__________________________________________________________________ The size of Memcached's
hash table is often very large. It is limited to available M_?_ across all the servers in the cluster of servers in a
data center. Where high volume, wide audience web publishing requires it, this may stretch to many gigabytes.
Memcached can be equally valuable for situations where either the number of requests for content is high, or the
cost of generating a particular piece of content is high.
6]
______________________________ ____________________________________ Memcached was originally
developed by Danga Interactive for LiveJournal. List at least two other systems, besides Facebook, that use
Memcached. Google App Engine, AppScale, Microsoft Azure and Amazon Web Services also offer a Memcached
service through an API.

Programs that do not compile are worth little, if anything.
If a print statement format is off, the penalties will often be less than the 25% per day late penalty; turn in the lab. You would not be
happy if you went to Best Buy and purchased a large screen TV that did everything except show the picture; you would consider it
pretty worthless. Most users consider software that does not work properly pretty useless as well. If the lab is not working correctly,
credit will be small (if any); you might be better to accept a 25% (1 day) late penalty and turn in the lab working correctly!
