Great post!

This may help you copy code correctly with indenting: Actully I was doing that, but I thought that typing the code would give me better understanding of it rather than just copy it what do you think? Type the code into a text file.

This is especially true because different people use the same database terms to mean different things.

Therefore, a good place to start our study is with a list and explanation of the most important database terms. Tip Reviewing Basic Concepts What follows is a brief overview of some basic database concepts.

It is intended to either jolt your memory if you already have some database experience, or to provide you with the absolute basics, if you are new to databases. Understanding databases is an important part of mastering MariaDB, and you might want to find a good book on database fundamentals to brush up on the subject if needed.

The term database is used in many different ways, but for our purposes a database is a collection of data stored in some organized fashion. The simplest way to think of it is to imagine a database as a filing cabinet. The filing cabinet is simply a physical location to store data, regardless of what that data is or how it is organized. New Term Database A container usually a file or set of files to store organized data.

Caution Misuse Causes Confusion People often use the term database to refer to the database software they are running. This is incorrect, and it is a source of much confusion.

The database is the container created and manipulated via the DBMS. A database might be a file stored on a hard drive, but it might not.

And for the most part this is not even significant as you never access a database directly anyway; you always use the DBMS, and it accesses the database for you. Rather, you create files within the filing cabinet, and then you file related data in specific files. In the database world, that file is called a table.

A table is a structured file that can store data of a specific type. A table might contain a list of customers, a product catalog, or any other list of information. New Term Table A structured list of data of a specific type. The key here is that the data stored in the table is one type of data or one list. You would never store a list of customers and a list of orders in the same database table. Doing so would make subsequent retrieval and access difficult. Every table in a database has a name that identifies it.

That name is always unique—meaning no other table in that database can have the same name. Database Basics 7 Note Table Names What makes a table name unique is actually a combination of several things, including the database name and table name.

This means that while you cannot use the same table name twice in the same database, you definitely can reuse table names in different databases. Tables have characteristics and properties that define how data is stored in them. These include information about what data may be stored, how it is broken up, how individual pieces of information are named, and much more. This set of information that describes a table is known as a schema, and schema are used to describe specific tables within a database, as well as entire databases and the relationship between tables in them, if any.

New Term Schema Information about database and table layout and properties. Note Schema or Database? Occasionally schema is used as a synonym for database and schemata as a synonym for databases.

While unfortunate, it is usually clear from the context which meaning of schema is intended. In this book, schema will refer to the definition given previously. Columns and Datatypes Tables are made up of columns.

A column contains a particular piece of information within a table. New Term Column A single field in a table. All tables are made up of one or more columns. The best way to understand this is to envision database tables as grids, somewhat like spreadsheets. Each column in the grid contains a particular piece of information.

In a customer table, for example, one column contains the customer number, another contains the customer name, and the address, city, state, and Zip Code are all stored in their own columns. Tip Breaking Up Data It is important to break data into multiple columns correctly.

Report Cards

For example, city, state, and Zip Code should always be separate columns. By breaking these out, it becomes possible to sort or filter data by specific columns for example, to find all customers in a particular state or in a particular city.

If city and state are combined into one column, it would be difficult to sort or filter by state. A datatype defines what type of data the column can contain. For example, if the column is to contain a number perhaps the number of items in an order , the datatype would be a numeric datatype. If the column were to contain dates, text, notes, currency amounts, and so on, the appropriate datatype would be used to specify this.

New Term Datatype A type of allowed data. Every table column has an associated datatype that restricts or allows specific data in that column.

Datatypes restrict the type of data that can be stored in a column for example, preventing the entry of alphabetical characters into a numeric field. Datatypes also help sort data correctly, and play an important role in optimizing disk usage.

As such, special attention must be given to picking the right datatype when tables are created. Rows Data in a table is stored in rows; each record saved is stored in its own row. Again, envisioning a table as a spreadsheet style grid, the vertical columns in the grid are the table columns, and the horizontal rows are the table rows.

Unlike other languages spoken languages such as English, or programming languages such as Java or Visual Basic , SQL is made up of very few words. Everything you need to know to start taking If city and state are combined into one column, it would be difficult to sort or filter by state.
