week 8

 this was the eighth week of my participation in the class. We started class as usual, but since a few weeks, we have changed the class to the lab of the library in order to get convenient when students wanted to improve their study on searching information. For this week, I and the other students were asked to form a group of 3 in terms of doing some searching on certain topic. My group was conducting on Methodology and some categories of it. Actually, I did not understand at all about this lesson, but when I did research with my group mates, I got some clear information which was shown by my friends. Basically, Methodology is a collection of Tools, Procedure, and Documentation Aids which help the system developers to implement a new information system. As we went through to the classifications of the Methodology, we could see that there were such a number of them which were very useful. However, the most common and important one are Gane and Sarson (STRADIS), Information Engineering (IE), Jackson System Development, Prototyping/Iterative Approach, and Structured Approach. My group was supposed to conducts on these components in order to clarify the meaning and concepts which would be used in the future.
     STRADIS is based on the building of a logical model system, using graphical to enable users, analysts, designers to get a clear and common picture of the system and how its parts fit together to meet user's meet. IE is an approach to designing and developing information system as well as an architectural approach to planning, analyzing, designing, and implementing applications within an enterprise. JSD is a method of  system development that covers software life cycle either directly, or by providing a framework into which more specialized techniques can fit. Prototyping/Iterative Approach is a program used to show proof of concept to senior management, to validate system specifications, and to explore solutions to specific usability and design problems. Last but not least, SA is the process of developing system or software to meet certain requirements.
    Even my group had found some of these definitions and concepts to make thing clear in this lesson, my lecturer said for the level of my learning now, I as well as the other students did not have to clarify the processes or the method for using of these Systems because it is totally complex for me to understand. Moreover, he said that being in this levels and understanding the classifications of Methodology is adequate for me to analyze.

Week 10, 11 & 12 Web Applications

This week, we went through a new topic which is about Web Applications. A web application is an application that is accessed over a network such as the Internet or an intranet. Internet Chatting, video conferencing, emails, online editing are some of the web applications we use in our daily basis. We also had a case study: the Web 2:0 and Web 1:0. Web 2:0 is "the popular term for advances Internet Technology and applications including blogs, wikis, Really simple Syndication (RSS) and social bookmarking." (Course Material). Web 2.0 includes social networking sites, video sharing sites, blogs and online communities. Web 2.0 is a change in how we use the Internet.  It isn’t simply a place to retrieve information anymore; it is a place to interact and communicate with others. We also went through the characteristics and components of Web 1:0 and Web 3:0.

Knowing this has made me realize the importance of web applications in our daily life, particularly Web 2:0.  The development of Web 2.0 has significantly changed how people view and use the Web in both a personal and a business sense. If a company wants to succeed in today’s high-tech environment, it is key that it is familiar with the concept of Web 2.0 and how it can best be applied to its Web presence. We then learn about Web information which is an information system using WWW as part of the deployment and implementation technology. We finally discussed about Google applications.

At the end, we were asked to develop a website by using sites Google. It's my first time to create a website but I find it exciting to learn all these tools because these skills can be useful to me today and tomorrow in our daily life.

Week09-FCC123 Introduction to Information Technology

 

This weeks topic was about the "Trends in the internet and WWW". We learned about the differences between the internet and the World Wide Web. Internet functions are transport mechanism. Global WAN that connects approximately 1 million organizational computer nets in more than 200 countries. Internet enables people to access data in other organization and to communicate, collaborate and exchange information around the world, quickly and inexpensively.
WWW is an application that uses those transport functions. The web handles all types of digital information including text, hypermedia, graphics and sound. Later on we learned about Web-based Computing. The web current computing models include server side computing (CGI) and client side computing (Applets) and were initially designed for processing fill-out forms. Then we learned how internet infrastructure works. For example, instant messaging. When log in to IM server, the server determines in any of user established friends, family, coworkers called buddies are online. When the sender send instant voice or video communications to online buddies, the message travels through a messaging server and then to the online buddy's computer.

Week07-FCC123 Introduction to Information Technology

Session 1

In this week we learned about database. We learned that database is the container or a collection of data. And it has four components: data, relationships, constraint, and schema….

Database management system: it’s software that create database. For example, Microsoft access

And then we learned that DBMS performs five primary functions: define, create and organize a database, input data, process data, maintain data integrity and security (it allows limited access of the database), and query database.

Later on, we moved to the Database system and this is different than data management system, and it is a computer based record keeping system.

We were exposed to the advantages of database system, it improves security, improves data integrity, controls redundancy and efficiency in accessing data.

There are four types of database model: Hierarchical database (organizes data in a tree structure “one to many”), network database (many to many relationship), Relational database (basically a table with rows: representing Field and columns: representing Record), and Object-relational database ( quite similar to relational database but this is one is highly object oriented language)

Session 2

We did a practical work creating a table form using Microsoft Access.

Week06-FCC123 Introduction to Information Technology Session 1,

 

In this week we were exposed the Information System Development Methodologies which was defined by Jayaratna as a contain models and reflect particular perspectives of ‘reality’ based on a set of philosophical paradigms. A methodology should tell you ‘what’ steps to take and ‘how’ to perform those steps but most importantly the reasons ‘why’ those steps should be taken, in that particular order. Maddison et al, defined as as a recommended collection of philosophies, phases, procedures, rules, techniques, tools, documentation, management and training for developers of information systems. 

Why do we need to use a Methodology? 

We learned that it makes the analysis and design process more accessible to non-experts. Also, to introduce structure into design and make it more manageable.

After this short brief, we had an activity which we had to search and reflect on the various methodology definitions.

Later on, we learned about the types of ISD methodologies: 

Structured approach (SDLC): is the oldest and most known methodology used to coordinate the efforts of information systems development is known as the "Waterfall". It covers many activities starts from understanding why the system should be built, studying the project feasibility, analyzing problems, choosing the system design and architecture, implementing and testing it, up to delivering the system as product to the user.

Jackson System Development (JSD): method of system development that covers the software life cycle either directly or, by providing a framework into which more specialized techniques can fit.

information engineering (IE): is an approach to designing and developing information systems.

Prototyping: An easily modified and extensible model (representation, simulation or demonstration) of a planned software system, likely including its interface and input/output functionality.

Gane and Sarsons (STRADIS): The methodology remains today as one of the most popular techniques for structured analysis and design of systems.

Session 2,

In this session, we were given a case study to work on. We needed to develop the system for AIU. Therefore, me and my group members, we chose TPS and EIS as a Information System, and SDLC as a methodology.

WEEK -4

This 4th week helped us to know about the information system(IS).

So, we understood the concept of a system in relation to information  system. information system on business can support in its processes, managerial discussion making and strategies to strengthen of information system for business application and IT relations with IT.

WEEK -5

well! this week was also about the information system (IS) where we will focus in various organization using information system.

so, here we learnt types of IS sub-dividing into operation support system (OSS) for business operation and management support system (MSS) for data management and IS level being used by TPS,DSS,MIS and ESS. we also learnt on other information system.

now, we know how IS helps to student knowledge, business information for any operation in the world.
