Dolphins have always cried out to people for trust. We associate stinks with kindness and joy. Although the dolphin is a MySQL symbol, it does not explain the popularity it has in the whole world:


Based on current statistics, MySQL takes first place in terms of popularity on the Internet among all existing relational database systems.

Features of MySQL

The procedure for creating a MySQL database is no different from other DBMSs. This cost-free nature is also the main reason for the popularity of this system. For example, SQL Server from Microsoft. The skin version of this product comes with a cost-free edition and is equipped with bad technical characteristics.

Features of the MySQL DBMS:

  • Most often it is used as a remote server;
  • Includes a large number of table types;
  • It is supplied with a special EXAMPLE type, which shows the principle of creating new tables;
  • High level of scalability for support of most popular platforms;
  • The open source code is where the DBMS is constantly being updated and modernized by hundreds of vendors around the world;
  • A large number of APIs have been created to ensure interactions between MySQL and the majority of all programs;
  • The maximum size of a database table file is limited by the capabilities of the operating system being used.

MySQL's closest competitor, the MS SQL Server system, has a cost-free Express edition with a database size of 10 GB.

  • The remaining version of the DBMS 5.7.5m15 (test) was released in the spring of 2014.

MySQL Database Creation

The main logical and structural unit of data in any relational model of information supply is the base. Instead, the server will go for it. Whether the database consists of a table, each of them is divided into tables. Let's look at all the ways to create a MySQL database.

The core of PHPMyAdmin is one of the most popular shells for working with MySQL. This interface has a lot to make database administration easier.

To create a MySQL database using PHPMyAdmin, do the following:

  • We go into the shell;
  • Go to the “Database” tab;
  • In the first field, enter the name of the created database, and from the list, select the required coding. Our vipadka has utf8_genegal_ci.

The database name does not have to exceed 64 characters.

  • Then we press the “Create” button:
  • After the created MySQL database name will appear in the list below:
Now let's create a table in our database. Robimo takes:
  • In the list of evils we find the name of our database and press on the new one:
  • At the next window, enter the name of the table and set the number of columns;
  • Then we press the “Ok” button.

You can do this by clicking on the “Create table” option just below the list of evil databases, otherwise in the next window you will see a workpiece without a name and with a number of options.

  • Next we will set the structure of our table. We write down the names and types of data that are stored in the table columns;
  • After this we click on the “Save” button:
  • Our MySQL database table has been created and is ready to be filled with data:
There is not only one way to create a database in PHPMyAdmin. A similar effect can be avoided by using SQL quickly. For this purpose the CREATE command is used. This is the syntax:

CREATE DATABASE db_name;

Argumenti:

  • IF NOT EXISTS – to ensure the uniqueness of the database name. If you do not specify this parameter, the dissolved base with the same name may fail to clear the Viconnaya;
  • db_name – indicates the name of the created database;
  • CHARACTER SET charset – the database encoding is installed. If it is not indicated, the meaning behind the rules is determined;
  • COLLATE collation – indicates the sorting order of the data. Non-linguistic parameter.

Now we can create the database using additional SQL via the PHPMyAdmin shell:

  • Go to the "SQL" tab;
  • In the editor's window, enter the entry into the created database;
  • Or we’ll emboss “I’ll ask” on the icon. Look at the list of databases:
  • Enter the following text:

CREATE DATABASE `my_db`;

  • Click on “Ok” at the bottom:
  • Following the name of our database will appear on the evil list:
To view the SQL database data, use the command DROP DATABASE “my_db” .
  • The query for creating the data base from the designated required language parameters will look like this:

CREATE DATABASE `my_db` CHARACTER SET utf8 COLLATE utf8_general_ci;

Setting up a backup copy of the database

The possibility of updating the data base is even more important. In times of non-transferable situations, updating can help you return lost information and quickly update the resource to work.

We set up a database backup with PHPMyAdmin. Procedure:

  • From the list of evils we select, we will need a database;
  • Embossed on the “Export” tab;
  • We press “Ok”.
If you select the “Initial” value in the “Export Method” section, you will see a large window with a variety of parameters for adjustment:
Now let’s try to update the saved copy of the database. From now on we can see the original copy. Go to the “Operations” tab and press the message “ Vidality database»:
To update the MySQL database in PHPMyAdmin, go to the “Import” tab. In the section " Import file» Be sure to select the location where you saved a copy of the database. The following is embossed on the “OK” button located at the bottom of the screen:
Sometimes, after making changes, you need to update not the entire database, but only the entire table. This functionality is also implemented in PHPMyAdmin. For which, on the side of the required table at the bottom of the structure, select the last item from the list and stamp “Ok” at the bottom:

Every new installation of CMS Joomla results in the creation of a new database. This database saves data such as articles/materials, menus, categories and accounts. This data is necessary for creating a website on Joomla!

To install Joomla, you are responsible for the working database, the database manager, the password for the database manager and the other types of privileges for the database manager.

This material will look at the most extensive type of database that is used when installing Joomla, the MySQL database itself. We will look at two options for creating a database for Joomla. The first method is for a created database on a local server, and the other is for a created database on a hosting, in which the emphasis is on the DirectAdmin wiki - hosting panel. Ale other panels keruvannya hosting culpable mothers are similar to the creation of the database.

Creating a MySQL database on a local server

In order to create a database on a local server, you need to install it first. Therefore, we install a local server - Denwer [Download] and install it. Instructions for installing Denwer .

After successfully installing the local server, you can begin creating the database for installing Joomla! In order to access the database database interface, you need to start the local Denwer server (if it is not running) and enter in the browser address bar: http://localhost/tools/phpmyadmin. In the window you will open the web interface “phpMyAdmin”. Now it is possible to open the center of the data base.

The database has already been created, and now you can proceed to install Joomla on your local server.

Creation of MySQL databases on hosting

As was said earlier, the creation of the database on the hosting will be carried out on the DirectAdmin server panel. But all stages of creation will be similar until any hosting control panel.

To create a database on your hosting, you need to log into your hosting control panel. It is your responsibility to know how to log into the hosting panel, when registering with your hosting, you are required to send all the information to your wiki. Otherwise, you can clarify any information by going to the technical support of your host.

Once you have reached the hosting panel, you can immediately begin creating the database.


Now you can install Joomla 2.5(or install Joomla 3.1) directly on the hosting and at the final stage of installation, you will be required to enter the data that needs to be written down (database name, client name, client password and host).

Nowadays, these data bases are widely stagnant in various areas: in enterprises, companies, initial mortgages, and so on. And a program with the Office package - Microsoft Access - allows you to work with them, which gives traders even wider options for interacting with tables. Robotic skills in Microsoft Access will be useful for every skin condition. In this article we will look at how to create an Access database. Let's get along. Let's go!

A database is a collection of interconnected information, combined in the form of a table. Having got out of this, what has happened in this way, you can move straight to the next step.

Butt of the creation of the base with a rich list

With Microsoft Access running, select "Create" from the "File" menu. Then click the “New Database” button. Right-hand at the window, indicate the name of the file and where it will be saved. After this, click the “Create” button. You can also quickly access one of the list of templates assigned by the utility. In such situations, it will be much easier to simply edit the template rather than create everything again on your own.

You will see a table with a single field. Place the cursor on the tab and select “Designer”. At the box that appears, you will be asked to change the name. Now you can start filling up the seeds at the “My Field” station. The next section “Type of data” will be remembered automatically, depending on what words or numbers you entered. The type of information given to the skin can be changed. There are these types of data:

  • textual;
  • MEMO field (used for object descriptions, which allows you to enter a large number of characters >255);
  • numerical;
  • date hour;
  • penny;
  • doctor;
  • logical (manually set up for fields, so that you can place “so” or “no”);
  • OLE object field (allows you to insert multimedia files: photos, videos);
  • hypervigilance;
  • attachment (used for saving several files in one field);
  • calculations (allows you to calculate the amount, difference, amount based on other data from the table);
  • master of substitutions.

In most types you will need only “numeric”, “text”, “penny”, “calculation” and “Date/hour”, these types of data are used most often. Below in the “Field Power” section you can increase the size of the field. If you have a text data type, there will be 255 in there. This means that you can enter 255 characters in this middle. Obviously, this is very rich, so you can reduce the size of the designated field to 30 (you can put any other number, depending on the order to stand). The goal is to ensure that the database takes up less disk space.

For different attributes, different types of data, example in the screenshot.

Having selected the numeric data type, you can set the name of the entry mask. This is required in order to display entered numerical values. The mask behind the additional spaces is set. For example, if the table contains passport numbers, then in order for these numbers to be displayed in a suitable format, set the mask “##########”. First 4 characters, then a space and another 6 characters. For phone numbers, you can enter the mask “8(###)-###-##-##”.

For the “Date/Hour” type, you can select different display formats from the “Field Power” section.

Don't forget to save the created table. You can earn money by using the key combination Ctrl+S. If, when saving, a window appears in advance and the key fields are not specified, click “None”, since they can be created later.

The save key is located on the top left corner.

As you can figure out, creating databases is a simple process that will help you get started. Write in the comments if the article helped you to become a nutritionist, then write if anything from the posted material has become unreasonable for you.

Today's computers allow you to process a wide range of highly sensitive information. Therefore, it is very important for the correspondent that the information is presented in a systematized, manual form.

For this purpose it is necessary to create a database in mysql.

Purpose and capabilities of the mysql DBMS

To structure various data, the most popular database management system, mysql, is used. With the help of a created mysql database, you can comfortably process information (add, delete, sort, change) that is saved in the computer’s memory.

Mysql is a relational database, which allows you to process and present data in the most convenient form for humans - tables.

Tables can be expanded when processing information:

  • efficiency;
  • bendiness;
  • shvidkodia.

The created mysql database is characterized by:

  • the speed of processing and support of the great obligations of these data;
  • the simplicity and reliability of the vikoristan;
  • there appears to be a rich set of red-blooded authorities;
  • This support is practically applicable to all operating systems.

The mysql DBMS will effectively stagnate in very complex situations and directly.
