chapter8: Assessing Organizational Information -Data Warehouse

1). Describe the role and purpose of data warehouses and data marts in the organization.

Data warehouse- A data warehouse is a collection of data, usually current and historical, from multiple databases that the organization can use for analysis and decision making. The purpose, of course, is to bring key sets of data about or used by the organization into one place.-

Data mart- Data marts are related sets of data that are grouped together and separated out from the main body of data in the data warehouse.

The purpose of data warehouse is to aggregate information throughout an organization into a single repository in such way that employee can make decision and undertake business analysis activities.
besides that, database store all the transaction such as sales of product.

The roles of data mart is easily to employee to access the data information. Other than that, data marts as having focuses information subsets particular to the needs of a given business unit such as finance or production and operations.

2). Explain the relationship between business intelligence and a data warehouse.

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 (thus the need of content management systems). 
Let me give the path of 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 datamarts or directly reporting from it. There are lot of tools/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.


chapter 7: Storing Organization Information-Database

1). Define the fundamental concepts of the relational database model..

What is database actually? macam mana database ni berfungsi?...manelah tahu benda ni..budak yang ambik sains komputer je kut yg tahu..<------is that your perception?kne banyak membaca ni..isk3...
DATABASE MANAGEMENT SYSTEM (DBMS)..


A collection of programs that enables you to store, modify, and extract information from a database. There are many different types of DBMSs, ranging from small systems that run on personal computers to huge systems that run on mainframes.
In example: computerized library system, automated teller machines  
                  (ATM)
 and flight reservation systems.
besides that,it is shows how the internal organization can affect how quickly and flexibly you can extract information from this database.
This software are gathered all of the information in one central database..


2). Evaluate the advantages of the relational database   
     model.


  • Increase flexibility - who access the database will able get the information based on their users of database.
  • Increase scalability and performance- which is to looked at the performance of organization. Scalability is how well the systems can adapt to increase demand. Meanwhile, performance is base on the how quickly systems performs during transaction.
  • Reduced information redundancy- which is to reduce duplication of information.
  • Increase information integrity(quality)-measure quality of  information.
  • Increase information security- which is to maintain information integrity using password, access levels and access control.
3). Define a database management system and its relationship    
     to a website.

Database Management System(DBSM) is how the software can interact within users and application programs. How the DBMS manipulate the data information through database. The example is online shopping.How the owner want to fulfill the customer demand with the information for the warehouse data. Besides that, organization can measure their performance using the website. Which is how many visitors every day reach to the website,

4). Explain why an organization would want to integrate its database.

the organization should integrates the database because to ensure there no duplication of information. Means, no need  difference people key in the same database information. it is also increase flexibility because difference users with difference purpose can using one database according to their purpose.
The organization increase their performances and quality of database.
