Relational database

Hierarchal Database “In the network model, the data are represented by collections of records and relationships between data are represented by links. This structure holds for the hierarchical model as well. The only difference is that, in the hierarchical model, records are organized as collections of trees, rather than as arbitrary graphs.”(http://codex.cs.yale.edu/avi/db-book/db6/appendices-dir/e.pdf, 17-10-2014) This database model use rules as each child has one parent and each parent can…

Teradata is basically a database that is designed to handle queries. It is a relational database management system for the world's largest commercial databases.

This week we learned lots about the decomposition of our relations we are creating in the database as well how to make the relations into normal forms, which there are three normal forms. I learned that there can be data that is redundant and therefore not useful for the database. This data has no integrity and can be misplaced and even confuse how the data can be used and retrieved. This type of problem must be avoided. I had a hard time understanding how the breaking down of one relation into…

SERVER PRODUCT ARCHITECTURE A few definitions provide a good starting point.…

Physical properties of PHB: PHB physical properties similar to polypropylene. However, PHB is perfectly isotactic and does not include any chain branching like, for instance, PE. During processing, it flows easily. It is insoluble in water and soluble in chloroform and other chlorinated hydrocarbons. It exhibits good barrier properties against oxygen and compared to other biopolymers. It possesses better physical properties than polypropylene for food packaging applications.
