# 6: Given a physical database containing tables and relationships and business requirements, create the necessary queries.

A relational database is a database that consists of a collection of tables with columns showing entities, and rows showing data. This type of database uses a primary key and foreign key. The foreign key in another table will point to the primary key of a table, and this is how tables can relate to each other. This permits for one-to-one, one-to-many, and many-to-many relationship between the data. An advantage of relational databases includes the ease of adding or modifying new tables and entities without needing to change the structure of the database already in place. Relational database have many features, including indexing, setting data type, and setting validation tests, all these help to ensure data integrity.

in the tables. I then came to a solution that worked for most tables but not all,

The SqlDataSource doesn’t do the “whole” job it needs a data bound control like a Gridview. The DataKeyNames specifies the PK (primary key). The DataSourceID tells what data source to point to.

A. Lab # : BSBA BIS245A-1 B. Lab 1 of 7 : Introduction to MS Visio and MS Access C. Lab Overview--Scenario/Summary TCOs: 1. Given a business situation in which managers require information from a database, determine, analyze and classify that information so that reports can be designed to meet the requirements. 2. Given a situation containing entities, business rules, and data requirements, create the conceptual model of the database using a database modeling tool. Scenario: You have been asked to create two conceptual database models using MS Visio Database Model Diagram Template. The purpose of this lab is to have you gain familiarity with the various modeling tools needed to create a conceptual model (entity relationship diagram) of a

When it comes to the data model, there exists a relationship that has three different representations for the reason that database requires the relationship between the tables. It goes hand-in-hand with one another without the relationship the tables would have no purpose. The information cannot be repetitive in order for the each table to work and provide the specific database that is related to the information. In different ways the tables in the Huffman Trucking Fleet Truck database

b) You are to clearly mark Primary and Foreign Keys as shown in the sample below:

8. Create the rest of the columns as they exist in the old mapping table; often you should be able to just drag the columns from the older mapping table into the new mapping table. The below diagram used the dragging mechanism.
