The database isutilized to be a technical term, but, with the rise of information technologyand computer systems all through our culture, the database has turn into ahousehold term.Types of DatabasesThere are a few types of databases; every type of database has its datamodel. They include; Hierarchical Model, Flat Model, Network Model and RelationalModel. The Flat Model DatabaseIn a flat model, there is a 2 dimensional collection of data. For example,there is one column of info and within this column it is unspecified that everydata will be connected to the other. For example, a flat model database comprisesonly area codes. W/in the database, there will be one column and every new roww/in that one column will be a new area code.The Hierarchical DatabaseThe hierarchical model database looks like a tree structure, like howWindows organizes files and folders. In a hierarchical database, every upwardlink is coated in order to keep data arranged in a specific order on a similarlevel list. For exaple, a hierarchal model database of sales, may list everydays sales as a separate file. W/in these coated file are all of the sales forthe day.The Network ModelIn a network model, the important feature is that a record is stocked upwith a link to other records - in result networked. These networks could be a lotof different kinds of info such as a disk address or node numbers. The Relational ModelThe relational model is the most famous database type and a powerful tool,not only to store info, but also to access it. Relational model databases are arrangedas tables. The attractiveness of a table is that the info can be added oraccessed w/out re-organizing the tables. A table could have a lot of recordsand every record can have a lot of fields. Tables are sometimes identified a relation. For example, a company couldhave a database identified customer orders, w/in this will be a few different relationsor tables all connecting to customer orders. Tables could include customer info(address, name, info, contact, customer number, etc) and other tables such asorders that the client previously purchased. It must be noted that each recordin a relational model database has its main key. A main key is a field that simplifiesto identify a record.
