||A library can be a collection of Books.

||A book can have a title, an author, a publisher, year of publication and a price.  

||Similarly, a Library member has a name, phone number and an address.  

||Now, let us see how we can store this data as individual tables of rows and columns.  

||Similarly, a Members table can have columns like Name and Phone,  

||And a Member Id to uniquely identify or distinguish each member. <pause>

||And we can track the books issued to members in a third table called BooksIssued.  

||This table will track the book issued, the member, date of issue, date of return, actual date of return, whether checked in or not.  

||For advanced topics on relational databases, refer to our other tutorials by visiting the website Spoken tutorial.org  

||Okay, let us now get started with our first Base database called “Library”!

||To create a new Database, let us first open the Base program.  

||Then, click on the Windows Start menu at the bottom left of the screen, then click on All Programs, then LibreOffice Suite,and LibreOffice Base.

|A pop-up window titled Database Wizard opens.  

||Click on the Next button to create a new database.

||Click on the Finish button in the following window.  

||This opens a Save As window.  

||Since we are building a Library database, we will type "Library" in the File Name text box.

||And then click on the Save button.

||To create a new table, click the Tables icon in the Database list on the left.  

||Click on the 'Create Table in Design View' in the Tasks list on the right.This opens another window.

||Here, type 'BookId' as the first column under Field Name.  

||Use the Tab key to move to the Field Type column.

||Since the BookId will be a different number for each book, select Integer as the Field Type from the dropdown list.

||Change the Field Properties in the bottom section.

||Change AutoValue from No to Yes.  

||In other words this field is also called the Primary Key.  

||Notice the yellow key symbol to the left of the BookId field.

||Let us see how we can choose Field Types for field names.  

||Field types can be text, integer, numeric, decimal or date.  

||Use text, for fields that have general information, for example, name, title, address.  

||Use Integer, numeric, decimal for fields that may contain only numbers,

|For example use numeric for a field with price information, Integer for years.

|Title, Field type Text, Author  

||Field type  Text, Published Year  

||Field type Integer

||Publisher  

||Field type Text

||Price  

||Field type Numeric

||Change the Length to 5 and Decimal places to 2.  

||Click the Format example button.  

||This opens the Field Format window.  

||Select Currency from the Category List and  INR from the Format List.  

|Click on the OK button. Now we have created all the columns for the Books table.

||Let us now save the table.  

||Click on the Save icon that is below the File menu.   

||Type 'Books' in the table name text box  

||and click on the ok button.  

||In the next tutorial, we will add data to the Books table and create the Members and BooksIssued tables.

||This brings us to the end of this tutorial
