Blog Entry 4.4 Database Design

In this Entity Relationship Diagram, there are three main Entities : Customer, Invoice, and Product.
Within each entity there are different attribute types such as Name, but a specific name such as John Smith is an Attribute. Each entity can be described as a table each containing rows and columns, the rows being records and columns being attributes. Each attribute type has its own data type dependent upon the type of information, such as name being text. The customer entity, contains attribute types such as Name, Address, and gender. It also contains a customer key, and ID number that is specific to the individual, such that it can be referred to later. The Product entity contains attribute types such as the type of product, the price and the Product key. Like the customer key it is a reference key used to compare and correlate data in other entites.

Blog Entry 4.3 Packet Switching Technology

Due the fact that there are many users online all the time and data is being sent and received simultaneously there needed to be a way in which to send information in a way that computers can understand that can be translated into usable information. Through the TCP many different messages can be sent over the internet via packets in any order that are reassembled later. When computer A wants to share info to computer C in the picture above, the binary data of the message sent from A is broken into manageable packets and delivered to C. This message sent from the computer A,  uses TCP to send its message to computer C using package switching. The IP sets the format for the packet and the location it is to be sent, the IP information tells the router where this location is ad sends it on it s way. These packets travel independently of one another and arrive out of order. Each packet has a header and it contains the destination and sending IP address as well as the order in which things should be arranged.
