Create a new database to store club information such as members, dates of lottery games played, types of lottery games played, tickets purchased for each date and winning numbers for each date. You can use any database program, but for a website it's best to stick with a popular website database such as MySQL or Oracle. MySQL is free and has a large online user support community. For example, MySQL.com has information on getting started with MySQL.
Add tables to your database for the information you'll be storing. Tables are the logical structures within a database that hold records. Typically, tables correspond to a single type of data or information. For example, you may have a members table, a played numbers table and a winning numbers table.
Input data records to your database tables. For example, you may want to start with something simple like the member list. Enter into the members table of your database a record for each lottery club member. Enter records using a command line interface or graphical interface according to the instructions for your database system.
Connecting to the database and testing
Write a software routine to connect your website pages to the database. The software routine will need to access your database and retrieve data for display on your website. Keeping with the MySQL example, MySQL.com offers an excellent overview of the process for building database-driven website software in PHP. If you aren't familiar with software development, you may want to hire someone to help.
Design website pages to display your lottery club data. Create a file for each page and write the page code in HTML using a text editor such as Notepad. You'll need code on each page that will cause your software routine to execute on your website server computer and retrieve data from your database.
Transfer the files to your website hosting service. Use an FTP utility program to transfer the database, software and website page files according to the instructions from your website hosting service provider.
Test the software and website pages. Access your lottery club website as a member would and verify that the website looks right and that the database information is being retrieved correctly. Make any necessary changes to fix problems.

How to Create an Online DatabaseIn Feburary 2016 13,

Before you can create an online database, you’ll need to set up a database server account at an Internet service provider. The provider owns and operates the server equipment and provides the software at their facility; you pay for the service and have access to the database. Database software offerings include Microsoft SQL Server, Oracle, MySQL, MongoDB and others; these platforms feature fast response times for busy websites. For websites that have relatively low amounts of activity, you can opt to create a Microsoft Access or FileMaker Pro database and upload it to the service provider.
Client Tools
In addition to the online account, you’ll need software tools on your PC to manage the database from your desktop. The database vendor provides management software that lets you create tables, indexes and other database structures; generally, the software is proprietary and works only with the vendor’s database. For example, Microsoft’s Management Studio desktop software lets you administer SQL Server databases.
Security
Online databases have an administrator’s user ID and password that grants complete access to the database. For best security, create additional user ID and passwords that access only those data items that are absolutely necessary for a specific purpose; otherwise, a hacker may gain control of your database and steal confidential information.
Loading Data
Once created, a database is an empty structure that may need useful data to function correctly. For example, an online toy store needs inventory records describing each toy for sale, including a model number, description and price. If you already have this information in another format -- a Microsoft Excel spreadsheet, for example -- you can use the client tool software to copy the Excel data into the database. If you do not have this data in a computerized form, you will need to key it in by hand.
Program Connection
Web programs use information in the online database to make the website work; the programs read the data and send the user Web pages based on the database content. Each program incorporates a piece of data called a connection string; the string specifies the database name, the server’s Internet Protocol address, a login ID and password, and other information. The program’s housekeeping section uses the string to open the database; other parts of the program search for data, change existing records or add new ones. To help keep your database secure, use restricted-access user IDs and passwords in your programs, not the administrator’s ID.
