• Apply four installation strategies: direct, parallel, single location, and phased installation.
• List the deliverables for documenting the system and for training and supporting users.
• Compare the many modes available for organizational information system training, including self-training and electronic performance support systems.
• Discuss the issues of providing support for end users.
• Explain why systems implementation sometimes fails.
• Explain and contrast four types of maintenance.
• Describe several factors that influence the cost of maintaining an information system.

ACTIVITY WEEK 13

In this week , we discuss about chapter 9 (Designing Databases) .In this chapter , we 
 learn how to 

• Concisely define each of the following key database design terms: relation, primary key, functional dependency, foreign key, referential integrity, field, data type, null value, denormalization, file organization, index, and secondary key.
• Explain the role of designing databases in the analysis and design of an information system.
• Transform an entity-relationship (E-R) diagram into an equivalent set of well-structured (normalized) relations.
• Merge normalized relations from separate user views into a consolidated set of well-structured relations.
• Choose storage formats for fields in database tables.
• Translate well-structured relations into efficient database tables.
• Explain when to use different types of file organizations to store computer files.
• Describe the purpose of indexes and the important considerations in selecting attributes to be indexed.

ACTIVITY WEEK 12

In this week, we have a quiz. This quiz covered two chapter. There are chapter 5(determine system requirement) and chapter 6(structuring system requirement:process modeling)).After we have done quiz, we discuss about chapter  8:Designing the Human Interface. In this chapter , we learn ;

• Explain the process of designing forms and reports and the deliverables for their creation.
• Apply the general guidelines for formatting forms and reports.
• Format text, tables, and lists effectively.
• Explain the process of designing interfaces and dialogues and the deliverables for their creation.
• Describe and apply the general guidelines for interface design, including guidelines for layout design, structuring data-entry fields, providing feedback, and system help.
• Design human-computer dialogues, including the use of dialogue diagramming.
• Discuss interface design guidelines unique to the design of Internet-based electronic commerce systems.

ACTIVITY WEEK 11

In this week , there are midterm exam . This exam covered 6 chapters. There are from chapter 1 to chapter 6. Mr Zaliman gave us 1hour and half to answer the questions.

Concisely define each of the following key data-modeling terms: conceptual data model, entity-relationship diagram, entity type, entity instance, attribute, candidate key, multivalued attribute, relationship, degree, cardinality, and associative entity.

Ask the right kinds of questions to determine data requirements for an information system.

Draw an entity-relationship (E-R) diagram to represent common business situations.

Explain the role of conceptual data modeling in the overall analysis and design of an information system.

Distinguish between unary, binary, and ternary relationships, and give an example of each.

ACTIVITY WEEK 8

In this week , we were discussing Chapter 6(STRUCTURING SYSTEM REQUIREMENT:PROCESS MODELING) and Chapter 7(STRUCTURING SYSTEM REQUIREMENT: CONCEPTUAL DATA MODELING) In the chapter 6, we learn about ;

• Describe the steps involved when identifying and selecting projects and initiating and planning projects.
• Explain the need for and the contents of a Project Scope Statement and Baseline Project Plan.
• List and describe various methods for assessing project feasibility.
• Describe the differences between tangible and intangible benefits and costs and the differences between one-time and recurring costs.
• Perform cost-benefit analysis and describe what is meant by the time value of money, present value, discount rate, net present value, return on investment, and break-even analysis.
• Describe the activities and participant roles within a structured walkthrough.

At the end of the class , we discuss about student register system and we try to produce dfd  in context level diagram and level 0.

ACTIVITY WEEK 7

In this week ,there are quiz. This quiz covered two chapter.There are Chapter 3(Managing the Information Systems Project) and Chapter 4 System Planning and Selection).Then, we were discussing Chapter 5 ; DETERMINE SYSTEM REQUIREMENT .In this chapter , we learn about how to design and conducting interviews and develop a plan for conducting an interview to determine system requirements.We also design, distribute, and analyze questionnaires to determine system requirements.By this chapter, we also get know about advantages and pitfalls of observing workers and analyzing business documents to determine requirements.In this chapter , we learn how computing can provide support for requirements determination and know about Joint Application Design (JAD).

• Use prototyping during requirements determination.
• Select the appropriate methods to elicit system requirements.
• Apply requirements determination to Internet applications.
