Time	Narration
00:00	Welcome to the Spoken tutorial on LibreOffice Base.
00:04	In this tutorial, we will learn about * What is LibreOffice Base?
00:09	* Prerequisites for using Base
00:12	* What can you do with Base?
00:14	* Relational Database basics, Create a new database, Create a table.
00:20	LibreOffice Base is the database front-end of the LibreOffice suite.
00:26	Base is the equivalent of Microsoft Access.
00:30	Base is free and open source software, free of cost and free to use and distribute.
00:37	Let us look at the prerequisites for using 'Base'.
00:41	Following are the System requirements for Microsoft Windows:
00:45	Microsoft Windows 2000 (Service Pack 4 or higher), XP, Vista or Windows 7, Pentium-compatible PC up to 1.5 Gb available hard disk space.
01:02	For Ubuntu Linux, here are the System requirements:
01:06	Linux kernel version 2.6.18 or higher; Pentium-compatible PC.
01:13	For both, Windows and Linux installation, we require 256 Mb RAM (recommended 512 Mb).
01:24	For complete system requirements, visit the Libreoffice website.
01:30	You will also need to install Java Runtime Environment which you can download at the following link.
01:38	Click on the red button in the centre that says 'Free Java Download'.
01:44	Once the file is downloaded, double-click on it and follow the instructions to install.
01:52	Let us now look at LibreOffice Base installation:
01:56	If you have already installed 'LibreOffice Suite' with the complete installation option
02:03	then you can access LibreOffice Base, by clicking on the Start menu at the bottom left of your screen.
02:12	Click on All Programs and then click on LibreOffice Suite.
02:21	If you have not installed LibreOffice Suite,
02:24	you can install Base by visiting the official website and clicking on the green area that says 'Download LibreOffice'.
02:37	Detailed instructions are available in the first tutorial of 'LibreOffice Suite'.
02:43	Remember, when installing use the 'Complete' option to install 'Base'.
02:50	Okay, let us go to the next topic now.
02:54	What can you do with LibreOffice Base?
02:57	With Base- you can store organized data,
03:02	perform data entries and view data using forms,
03:08	retrieve information using queries and
03:12	design and generate nice, printer-ready reports.
03:17	Base helps you to manage databases.
03:21	As you may know, a database is a group of data, forms, queries and reports.
03:29	For example, 'Base' can be used to manage 'Customer Information database's,
03:36	track sales orders and invoices, maintain student grade databases or build a library database.
03:47	Let us now learn about some basics of databases.
03:51	A database has data stored and organized into tables.
03:56	Tables have individual pieces of data stored in rows and columns.
04:03	Such a database is also called a relational database where the tables have relationships with each other using the columns.
04:15	Let us consider a simple database for a Library.
04:20	A library can be a collection of Books.
04:23	And books can be issued to members of the library.
04:28	A book can have a title, an author, a publisher, year of publication and a price.
04:37	These are called characteristics or attributes.
04:42	Similarly, a Library member has a Name, phone number and an address.
04:48	And the library issues books to its members only.
04:54	Now, let us see how we can store this data as individual tables of rows and columns.
05:02	Information about each book can be stored in a Books table,
05:08	with its attributes becoming the columns: book title, author, publisher, year of publication and price.
05:19	To distinguish each book, let us also add a unique identifier column called BookId.
05:27	This way, we can have two completely different books with the same title.
05:33	Similarly, a Members table can have columns like Name and Phone,
05:40	and a Member Id to uniquely identify or distinguish each member. <pause>
05:47	And we can track the books issued to members in a third table called BooksIssued.
05:56	This table will track the book issued, the member, date of issue, date of return, actual date of return, whether checked-in or not.
06:09	We can establish relationships among these tables, to interlink the data in them.
06:16	Now this helps us to manage 'relational databases'.
06:22	For advanced topics on relational databases, refer to our other tutorials by visiting the website Spoken tutorial.org
06:35	Okay, let us now get started with our first Base database called “Library”!
06:43	To create a new Database, let us first open the Base program.
06:50	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.
07:08	A pop-up window titled Database Wizard opens.
07:13	Click on the Next button to create a new database.
07:19	Click on the Finish button in the following window.
07:23	This opens a Save As window.
07:27	Since we are building a Library database, we will type "Library" in the File Name text box
07:35	and then click on the Save button.
07:39	Now we are in.
07:42	Next, let us create tables to store data.
07:46	To create a new table, click the Tables icon in the Database list on the left.
07:54	Click on the 'Create Table in Design View' in the Tasks list on the right. This opens another window.
08:05	Here, type 'BookId' as the first column under Field Name.
08:13	Use the Tab key to move to the Field Type column.
08:18	Since the BookId will be a different number for each book, select Integer as the Field Type from the drop-down list.
08:32	Change the Field Properties in the bottom section.
08:36	Change AutoValue from No to Yes.
08:41	This field now will uniquely identify each book.
08:46	In other words, this field is also called the Primary Key.
08:52	Notice the yellow key symbol to the left of the BookId field.
08:58	Let us see how we can choose Field Types for Field names.
09:05	Field types can be text, integer, numeric, decimal or date.
09:13	Use text for fields that have general information, for example- name, title, address.
09:22	Use Integer, numeric, decimal for fields that may contain only numbers.
09:30	For example- use numeric for a field with price information, Integer for years.
09:39	Let us create the rest of the fields now.
09:43	Title- Field type Text, Author-
09:52	Field type Text, Published Year-
09:59	Field type Integer,
10:05	Publisher-
10:09	Field type Text,
10:11	Price-
10:14	Field type Numeric.
10:18	Change the Length to 5 and Decimal places to 2.
10:25	Click the Format example button.
10:29	This opens the Field Format window.
10:33	Select Currency from the Category List and INR from the Format List.
10:42	Let us choose Rs. 1234.00 that has two decimal places.
10:54	Notice that the total length is five, inclusive of the two decimal places.
11:02	Click on the OK button. Now we have created all the columns for the Books table.
11:11	Let us now save the table.
11:14	Click on the Save icon that is below the File menu.
11:20	Type 'Books' in the Table Name text box.
11:25	Note that it is saved in the same location as the database ‘Library’ as tables are a part of a database.
11:36	And click on the OK button.
11:39	In the next tutorial, we will add data to the Books table and create the Members and BooksIssued tables.
11:50	This brings us to the end of this tutorial.
11:54	To summarize, we covered the following:
11:58	* What is LibreOffice Base?
12:01	* Prerequisites for using Base
12:03	* What can you do with Base? 'Relational Database basics'
12:08	* Create a new database, Create a table.
