1.Describe two primary method of integrating information across multiple database? 

The primary method integrating information across multiple database is a forward integration takes information entered into a given system and sends it automatically to all downstream systems and process.Secondly,a backward integration takes information to all downstream systems and process.
 
2.Describe the benefit of data-driven web site ?

The benefits of data driven web site is to allow the website owner to make changes any time,a status website requires a programmer to make updates.It useful to when site offers a great deal of information,products,or services.A static website requires a programmer to make updates.This adds an unnecessary layer between the business and its web content,which can lead to misunderstandings and slow turn a round and desired changes.

 3.Define the fundamental concept of the rational database model?

fundamental concept of rational database model have two types firstly entities and attributes.Entities in the rational database model is the person ,place,thing,transaction or event about which information is stored.Attributes also called fields or columns are characteristic or properties of an entity class.Secondly keys and relationships.

4.Evaluate the advantages of the rational database model?

Firstly increase flexibility.increased scalability and performance. It database tend to mirror bushiness structures  ad good database can handle changes quickly and easily.It reduced information redundancy.Redundancy is the duplication of information,or storing the same information in multiple places.Besides that, increased information integrity(quality) and increased information security.

5.Compare operational integrity constraints and business-critical integrity constraints?

Operational integrity constraints are rules that enforce basic and fundamental information-based  constraints and Business-critical integrity constraints are rules that enforce rules vital to an organization success and often require more insight and knowledge than operational integrity constraints.

MEASURING THE SUCCESS OF STRATEGIC INITIATIVES

Introduction 

•  IT professionals know how to install and maintain information systems

•   Business professionals know how to run a successful business

Measuring IT's Success

•   Key Performance Indicators (KPI)

How an organization defines and measures progress toward its goals

Key Performance Indicators, also known as KPI or Key Success Indicators (KSI), help an organization define and measure progress toward organizational goals. 

Once an organization has analyzed its mission, identified all its stakeholders, and defined its goals, it needs a way to measure progress toward those goals. Key Performance Indicators are those measurements.

EFFICIENCY & EFFECTIVENESS IT METRICS

Efficiency:

 

There is 6 common types of Efficiency in IT metrics

1. Throughput : amount of info that can travel in system at any point
2. Speed : the times takes for a system to perform a transaction
3. Availability : available number of hours in a system to be use by customer and employee
4. Accuracy : the extents to which a system generates the correct results when executing the same transaction numerous time
5. Web traffic : number of page views, number of unique visitors and average spend on viewing the web page
6. Response time : time takes to respond to user interactions such as mouse click 

Effectiveness:

• Usability = the ease which people perform transaction/ find info. E.g: unlimited use of internet
• Customer satisfaction = benchmarks such as surveys, percentages of existing customers retained & etc
• Conversion rates = number of customers an organizations touches for the first time and convince to purchase its product or services
• Financial = the cost benefit analysis, breakeven analysis

Business in Facebook. How efficiency and effectiveness? 

Efficiency:

• Easy for the dealer to discuss or dealing with the buyers
• It is easy, low cost, and did not take to much times to promote about new product
• Very fast and very simple
• Can post advertisements just in second so everyone can see it less than minutes
