A database is a structured collection of data typically stored electronically in a computer system. MySQL is a relational database that stores data in tables with columns and rows. To retrieve data from MySQL using PHP, a connection is established using mysql_connect, then a SELECT query is run with mysql_query to get results from a table which can be fetched and printed.

Module 03 Lab WorksheetWeb Development Using LAMPLab Activities:· Create a database in MySQL· Import data into MySQL· Access a MySQL database using SQL· Connect to a MySQL database using PHP· Integrate SQL query results into a Web page· Run an SQL query from a Web form
Introduction
Download the sample data file TestData.csv.zip and unzip it.
Note that the file is in plain ASCII, with Unix line endings and uses the pipe symbol (|) as a field delimiter. You’ll need to know this when you import it into your database.
Over the course of this worksheet I’ll be asking you questions about MySQL commands. You can find documentation at http://dev.mysql.com. I encourage you to use this to answer the worksheet questions. You can also get some of your answers from PHPMyAdmin itself as we work through the exercise but this will help you get more familiar with the SQL language.
Evaluate Your Data
Open the sample data file in a spreadsheet program and examine the data. In the following table, list the names, description and data types for each field.
Field Name (from file)
Description
Data Type
Create Database
Before you import unformatted data into MySQL, you have to have a place to put it.
You can import data in three ways:
· Use a compatible table of an existing database
· Create a new table in an existing database either manually or by importing.
· Create a new database with a table that fits the incoming data.
Log into PHPMyAdmin.
Create a new database called dbtest. What SQL command would you use?
Since it’s not a good idea to use the MySQL administrator account root for everything, we’ll create a new MySQL user that will be managing this new database.
Create a new user with a user name consisting of your first initial followed by your last name. For example, Ellie Palka would create a user named epalka.
This will be a user for localhost only and has no access to any databases. The password will be the same as the username (we can change it later).
In other words, the full user name for Edith Palka would look like [email protected] with a password of epalka. (Remember to substitute your own first initial/last name for the user ID.)
What is your user name?
What was the SQL command you would use to create this user?
A user with an easily-guessed password is insecure but this is only for testing purposes and we can change the password later.
Now give the user you just created administrative access to the database dbtest. That is, they should have full control over the database dbtest and no others. What SQL command would do that?
Confirm that your user has full access to dbtest. How would you show this with an SQL command without logging in as that user?
Run that command, if you haven’t already. What was the output?
Log out and log back in as your new user to confirm that they can administer dbtest and nothing else. If this works, continue with th.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

2. what is a database? A database is a structure that comes in two flavors: a flat database and a relational database. A relational database is much more oriented to the human mind and is often preferred over the gabble-de-gook flat database that are just stored on hard drives like a text file. MySQL is a relational database. In a relational structured database there are tables that store data. The columns define which kinds of information will be stored in the table. An individual column must be created for each type of data you wish to store (i.e. Age, Weight, Height). On the other hand, a row contains the actual values for these specified columns. Each row will have 1 value for each and every column. For example a table with columns (Name, Age, Weight-lbs) could have a row with the values (Bob, 65, 165).
3. why use a database? Databases are most useful when it comes to storing information that fits into logical categories. For example, say that you wanted to store information of all the employees in a company. With a database you can group different parts of your business into separate tables to help store your information logically. Example tables might be: Employees, Supervisors, and Customers. Each table would then contain columns specific to these three areas. To help store information related to each employee, the Employees table might have the following columns: Hire, Date, Position, Age, and Salary.
4. mysql database A MySQL database is nothing in itself. Rather a MySQL database is a way of organizing a group of tables. If you were going to create a bunch of different tables that shared a common theme, you would group them into one database to make the management process easier.
5. mysql syntax There are many keywords in MySQL, and a good programming habit when using ANY of these words is to capitalize them. This helps draw them out from the rest of the code and makes them much easier to read. Below is an example of a MySQL query written in PHP that retrieves all the data from a MySQL table named "example". $result = mysql_query("SELECT * FROM example") That line of code is valid PHP, but it also contains valid MySQL. The text that appears between the quotations "SELECT * FROM example", is the MySQL code. As you probably can tell "SELECT" and "FROM" are the MySQL keywords used in this query. Capitalizing them allows you to tell from a quick glance that this query selects data from a table.
6. creating your first database Server - localhost Database - test Table - example Username - admin Password -
7. mysqllocalhost f you've been around the internet a while, you'll know that IP addresses are used as identifiers for computers and web servers. In this example of a connection script, we assume that the MySQL service is running on the same machine as the script. When the PHP script and MySQL are on the same machine, you can uselocalhost as the address you wish to connect to. localhost is a shortcut to just have the machine connect to itself. If your MySQL service is running at a separate location you will need to insert the IP address or URL in place of localhost.
8. mysql connect Before you can do anything with MySQL in PHP you must first establish a connection to your web host's MySQL database. This is done with the MySQL connect function.
9. Sample 1 <?php mysql_connect(“server", “database", “password") or die(mysql_error()); echo "Connected to MySQL<br/>"; mysql_select_db("test") or die(mysql_error()); echo "Connected to Database"; ?> //Connected to MySQL // Connected to Database
10. mysql tables A MySQL table is completely different than the normal table that you eat dinner on. In MySQL and other database systems, the goal is to store information in an orderly fashion. The table gets this done by making the table up of columns and rows.
11. create table mysql Before you can enter data (rows) into a table, you must first define what kinds of data will be stored (columns). We are now going to design a MySQL query to summon our table from database land.
12. Sample 2 <?php // Make a MySQL Connection mysql_connect(“server", “database", “password") or die(mysql_error()); mysql_select_db("test") or die(mysql_error()); // Create a MySQL table in the selected database mysql_query("CREATE TABLE example( id INT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), name VARCHAR(30), age INT)") or die(mysql_error()); echo "Table Created!"; ?>
13. 'mysql_query ("create table example' The first part of the mysql_query told MySQL that we wanted to create a new table. The two capitalized words are reserved MySQL keywords. The word "example" is the name of our table, as it came directly after "CREATE TABLE". It is a good idea to use descriptive names when creating a table, such as: employee_information, contacts, or customer_orders. Clear names will ensure that you will know what the table is about when revisiting it a year after you make it.
14. 'id int not null auto_increment' Here we create a column "id" that will automatically increment each time a new entry is added to the table. This will result in the first row in the table having an id = 1, the second row id = 2, the third row id = 3, and so on. The column "id" is not something that we need to worry about after we create this table, as it is all automatically calculated within MySQL. Reserved MySQL Keywords: Here are a few quick definitions of the reserved words used in this line of code: INT - This stands for integer or whole number. 'id' has been defined to be an integer. NOT NULL - These are actually two keywords, but they combine together to say that this column cannot be null. An entry is NOT NULL only if it has some value, while something with no value is NULL. AUTO_INCREMENT - Each time a new entry is added the value will be incremented by 1.
15. primary key (id)' PRIMARY KEY is used as a unique identifier for the rows. Here we have made "id" the PRIMARY KEY for this table. This means that no two ids can be the same, or else we will run into trouble. This is why we made "id" an auto-incrementing counter in the previous line of code.
16. 'name varchar(30),' Here we make a new column with the name "name"! VARCHAR stands for "variable character". "Character" means that you can put in any kind of typed information in this column (letters, numbers, symbols, etc). It's "variable" because it can adjust its size to store as little as 0 characters and up to a specified maximum number of characters. We will most likely only be using this name column to store characters (A-Z, a-z). The number inside the parentheses sets the maximum number of characters. In this case, the max is 30.
17. 'age int,' Our third and final column is age, which stores an integer. Notice that there are no parentheses following "INT". MySQL already knows what to do with an integer. The possible integer values that can be stored in an "INT" are -2,147,483,648 to 2,147,483,647, which is more than enough to store someone's age!
19. mysql insert When data is put into a MySQL table it is referred to as inserting data. When inserting data it is important to remember the exact names and types of the table's columns. If you try to place a 500 word essay into a column that only accepts integers of size three, you will end up with a nasty error!
20. Sample 3 <?php // Make a MySQL Connection mysql_connect("localhost", "admin", "1admin") or die(mysql_error()); mysql_select_db("test") or die(mysql_error()); // Insert a row of information into the table "example" mysql_query("INSERT INTO example (name, age) VALUES('Timmy Mellowman', '23' ) ") or die(mysql_error()); mysql_query("INSERT INTO example (name, age) VALUES('Sandy Smith', '21' ) ") or die(mysql_error()); mysql_query("INSERT INTO example (name, age) VALUES('Bobby Wallace', '15' ) ") or die(mysql_error()); echo "Data Inserted!"; ?>
21. mysql query So far we have seen a couple different uses of PHP's mysql_query function and we'll be seeing more of it as nearly all MySQL in PHP is done through the MySQL Query function. We have already created a new table and inserted data into that table. In this lesson we will cover the most common MySQL Query that is used to retrieve information from a database.
22. retrieving data with php & mysql Usually most of the work done with MySQL involves pulling down data from a MySQL database. In MySQL, data is retrieved with the "SELECT" keyword. Think of SELECT as working the same way as it does on your computer. If you wanted to copy some information in a document, you would first select the desired information, then copy and paste.
23. Sample 4 <?php // Make a MySQL Connection mysql_connect("server", "user", "password") or die(mysql_error()); mysql_select_db("test") or die(mysql_error()); // Retrieve all the data from the "example" table $result = mysql_query("SELECT * FROM example") or die(mysql_error()); // store the record of the "example" table into $row $row = mysql_fetch_array( $result ); // Print out the contents of the entry echo "Name: ".$row['name']; echo " Age: ".$row['age']; ?>
