The first task for most users will be to create a database. Notice the 'buttons' at the left of the main window. Clicking on these allows you to see the names of different <em>objects</em> that are stored in your database, which should be empty at the moment.<p> Click the <em>Tables</em> and <em>New</em> buttons to bring up the window shown below. This will allow you to specify the structure of the new table. It is important to note that if you haven't specified a database when starting up PgAccess, this table will be created in the database named <samp><username></samp>, your username.<p> Assume that you want to create a table with entries describing bibliographic references in the field of psychology. Choose a table name, such as <samp>psyref</samp> that will be easy to recall and find in a list. Enter the table name in the first input field.<p> When you already have tables in a database, you can use the <em>Inherits</em> button to toggle a list of existing tables to inherit characteristics of another table. In this example, there should be no previous tables to use.<p> Enter each field, giving it a name, field type and size, if the field type does not imply the size. That is, if your first field was to be a sequence number, and you selected <em>int2</em> as the field type, you would not have to specify a field size. However, if your second field was to contain the author of the reference, and was a <em>varchar</em> type, you would have to specify how many characters would be allowed in the field.<p> As you enter each field, click the <em>Add field</em> button to add it to the list at the right side of the window. You can change the position of fields using the <em>Move field up</em> and <em>Move field down</em> buttons, or delete a field if you decide it isn't what you wanted. When you are finished specifying fields, press the <em>Create table</em> button.<p> <img src="newtable.jpg" border=1 align=right> <a href="index.html#tut">Back to index</a> </body></html>
