Here are my experiment with installing Oracle Linux Server (Enterprise Edition) on VMware server 2 (free edition).1. Choose "Create Virtual Machine" on Summary tag.2. Enter Name of Virtual Machine you want to create, if you have more than one datastore, choose one. click Next.3. On the radio button choose "Linux Operating" with version "Other 2.6.x Linux (32-bit)"4. Set virtual Memory and

In this post we will discuss about how to do the normalization. The picture below is an example ER diagram that normalization will be done.After we learned ER diagram above carefully, then the first thing we will do is called mapping in the form of a table. Note the relationship between the entities and attributes that are in it, because the relationship between entities is important in making

In his seminal paper on the relational data model, E.F. Codd formulated a number of design principles for a relational database (Codd, 1970). These principles were originally formalized in terms of three normal forms: first normal form, second normal form and third normal form. The process of transforming a database design through these three normal forms is known as normalization. By the mid-

1. Database DefinitionThe database (English language: a database), or often also spelled database, is the collection of information stored in the computer so that it can be systematically examined using a computer program to obtain information from the data base. Software used to manage and call the query (query) of data base is called the database management system (DBMS).Basic concept of the

The idea of a chart to represent data in a system that is not new. In the year 1967, Martin and Estrin introduce an algorithm program by using the circle and arrow symbols to represent data flow. E. Yourdan and L.L. Constantine also use this notation symbols to describe the flow of data in the design program. GE Whitehouse 1973 also use the notation to make this kind of model systemmathematics.

CONCEPT OF INVESTIGATION SYSTEMThere are some point about Investigation System Concept, which the following:1. Discrepancy between the objective of system and the real condition of system2. Problem detection report is not real, because:- the objective is too ideal- lack of attitude and resources- system measuring is not accurate- the objective of system which have to be left behind- difference

There are two approach groups in defining system, that is emphasizing at its procedure and emphasizing at component or its element. Approach of more emphasizing at system of procedure define the following system:System are network work from procedures which is interaction, gathering together to conduct an activity or to finish an certain target.Approach of system representing network work from

The Importance of System DevelopmentSystem development can mean to compile a new system to replace a whole old ones system or to improve or to repair the system. Mentioned matter can be caused of several things:1. Existence of problems.Problems can be arising from:a. Unfinished problem.That is: intended deceivingly which can cause of danger to the properties and the truth of company data
