CHAPTER 8 -> Accessing Organizational Information (Data Warehouse)


1. ROLES AND PURPOSES OF DATA WAREHOUSES AND DATA MART IN ORGANIZATION 
The purpose of the Data Warehouse in the overall Data Warehousing Architecture is to integrate corporate data.  It contains the "single version of truth" for the organization that has been carefully constructed from data stored in disparate internal and external operational databases.
The amount of data in the Data Warehouse is massive.  Data is stored at a very granular level of detail.  For example, every "sale" that has ever occurred in the organization is recorded and related to dimensions of interest.  This allows data to be sliced and diced, summed and grouped in unimaginable ways. 
          Typical Data Warehousing Environment



Contrary to popular opinion, the Data Warehouses does not contain all the data in the organization.  It's purpose is to provide key business metrics that are needed by the organization for strategic and tactical decision making.

Decision makers don't access the Data Warehouse directly.  This is done through various front-end Data Warehouse Tools that read data from subject specific Data Marts.

The Data Warehouse can be either "relational" or "dimensional".  This depends on how the business intends to use the information.


2. The relationship of business intelligence and data warehousing 
 changing data into information and knowledge.
Many of the tool vendors who sell their products or software call it business Intelligence software rather than Data warehousing software. so what is it? 

Business Intelligence is a term commonly associated with data warehousing. Business Intelligence is a generalized term where a company initiates various activities to gather today's market information which also includes about their competitor. Today's business Intelligence systems are contrasted to more classical way of information gathering in mining and crunching the data in the most optimal manner. In short we can say BI simplifies information discovery and analysis. 

In this way the company will have a competitive advantage of business and intelligently using the available data in strategic and effective decision making. it has the ability to bring disparate data under one roof  with a meaningful information and ready for analysis.
so what has Data warehousing to do with Business Intelligence?

Business intelligence usually refers to the information that is available for the enterprise to make decisions on. A data warehousing (or data mart) system is the backed  or the infrastructural, component for achieving business intelligence. Business intelligence also includes the insight gained from doing data mining analysis, as well as unstructured data.

Example, data warehousing. All the source data from disparate sources are used to load/Stage data. Different sources can be flat files, another database or some other process. The starting point of the Data warehouse should extract the data in order to load into its environment.This is extracting. This data may not be the expected format or size. your business demands are different or your organization business requirements are different. So the business process has to modify the data or better word is to transform the incoming data to meet requirements and objectives. This is called Transformation. 

Once every slicing and dicing of the data is done along with applied business rules, this data is ready for loading into the target tables. This process is called Loading. So overall till now we have done Extraction, Transformation and Loading. In short we call this ETL. There are lot of tools available in today's market which does help in achieving the ETL process. Once this data is loaded in to the database, this is ready for next processing. We call that database as Data warehouse database. 

The next process could be building of data marts or directly reporting from it. There are lot of tools or software available for reporting/analysis. Some call it business reporting or analysis tool. But if you see the whole process has intelligence involved in business. we can call this or the gurus call it Data warehousing and the system involved from end to end is called business intelligence system.

STORING ORGANIZATIONAL INFORMATION - DATABASES

 Hye. This is the answer for the learning outcome.



(1) define the fundamental concepts of the relational database model


Concept of a database is that of a collection of records or pieces of information which is a structural description of the type of facts held in database known as a schema. Schema describe the objects that are represented in the database and the relationships among them. There are ways of organizing a schema modelling the database structure known as database models or data models. but nowadays, Relational model is commonly used which is all information in the form of multiple related tables each consisting of rows and columns. this model represents relationships by the use of values common to more than one table. Hierarchy model and the network model is use a more explicit representation of relationships.
(2) evaluate the advantages of the relational database model 

  • increased flexibility
  • increased scalability and performance
  • reduced information redundancy
  • increased information integrity (quality)
  •  increased information security

INCREASED FLEXIBILITY
  • good database that can handle changes quickly and easily
  • physical view of information deals with the physical storage of information on a storage device such as a hard disk
  • logical view of information focuses on how users logically access information to meet their particular business needs
INCREASED SCALABILITY & PERFORMANCE
  • scalability refers to how well a system can adapt to increase demand
  • performance measures how quickly a systems performs a certain process or transaction

REDUCED INFORMATION REDUNDANCY
  • redundancy is the duplication of information, or storing the same information in multiple places
  • occurs bcoz organizations frequently capture and store the same information in multiple locations.
  • primary problem with redundant is that it is often inconsistent which makes it difficult to determine which values are most current or most accurate
INCREASED INFORMATION INTEGRITY (QUALITY)
  • measures of the quality of information
  • database environment, integrity constraints are rules that help ensure the quality of information 
  • two types of integrity:
(1) relational integrity constraints - enforce bacic & fundamental information based constraints
(2) business (critical integrity constraints) - enforce business rules vital to an organization's success and often require more insight and knowledge than relational integrity constraints

INCREASED INFORMATION SECURITY
  • organizational asset
  • as systems become increasingly complex and more available over the internet, security becomes an even bigger issue
  • offer many security features including passwords access levels, and access controls
  • password provide authentication of the user
 (3) define the database management system (DBMS) and its relationship to a website
 DBMS is software through which users and application programs interact with a database. The user sends requests to the DBMS and the DBMS performs the actual manipulation of the information in the database. there are two primary ways that users can interact with a DBMS, directly and indirectly. 

(4) explain why an organization would want to integrate its database

by integrating its systems or building connections between its many database, its allow the organizations multiple system to automatically communicate by passing information between the databases, eliminating the need for manual information entry into multiple systems because after entering the information once, the integrations send the information immediately to all databases. the integrations not only enable the different departments to share information, but have also dramatically increased the quality of the information. without integrations, an organization will,
1. spend considerable time entering the same information in multiple system
2. suffer from the low quality and inconsistency typically embedded in redundant information

Chief Knowledge Officer (CKO)
CKO are responsible in collecting, maintains and distributing the organization's knowledge. CKO also will create the system so that the information can stored easily and can be reuse knowledge. The CKO also make sure that all the employees are updated the organization.
 

 




Effectiveness of Facebook Marketing

A lot has been made of the performance of Facebook in recent months. In particular, conflicting reports have shown to be both an effective means for business to target their advertising dollors. But despite those dueling finding, small business may not want to automatically write off advertising on Facebook, especially if it is done correctly and expertations are managed.

Social  media education company said. "Compare this to the yellow pages,radio,TV,print where you get the ad, but you do not get the list. With facebook, business owner can create a growing community of potential customer that will be with them for years potentially. "Simply put, Facebook when used effectively, are able to benefit greatly from word for mouth advertising in a way that other ads cannot. On Facebook, you see other fans of a business or product. You see your friends like them. This things matter and make for more effective  marketing channel. Ever, I can target an ad to editors that work at BusinessNewsDaily. That gives a business access to marketing gold and relecance."


Effective.
One of the biggest benefits for facebook advertising is that you are reacting your target demographic in their comfort zone. When a person is logged into their facebook page, they are confortable. When they see your ad on facebook page there is a certain amount of trust that is inherent and that you don't get when seeing a random link on a Google search. That trust can be a particularly important factor in the effectiveness of advertisements on facebook. Then main difference between a facebook page and a traditional Web page is you can see customer feedback. If someone click on your facebook ad and goes to your page, they can actually read what other people are saying about you. That helped uild trust among your client base.

·         If customer relationships are the heart of business success, then CRM is the valve the pumps a company's life blood.
·         Steve Horne, president of ANALYTICi, the CRM and database division of ad agency giant Foote, Cone & Belding, says, "People like to feel special. "

·         Dianne Durkin, president of Loyalty Factor LLC, a training and consulting firm in Portsmouth, NH, says customers want human interaction--most of all, they want someone who understands and can respond to their needs
·         CRM applications are applications that run on the same principals as Microsoft Word and Excel. There are many values that can be filled in.

·         Successful Customer Relationship Management navigation is becoming increasingly important in today's competitive business world.
·         Customer expectations are always increasing, and business services must increase along with these expectations.
·         CRM is the method through which businesses can connect with their customers and therefore serve them better.
·         Businesses with successful CRM strategy and applications will notice a large increase in sales, customer satisfaction, and simply the overall success of the business.
