Difference between B and B+ tree in database

B tree indices are similar to B+ tree indices. The primary distinction between the two approaches is that a B-tree eliminates the redundant storage of search key values. Search keys are not repeated in B tree indices.
Given below the major difference between B tree and B+ tree structure.

1. In a B tree search keys and data stored in internal or leaf nodes. But in B+-tree data store only leaf nodes.
2. Searching of any data in a B+ tree is very easy because all data are found in leaf nodes otherwise in a B tree data cannot found in leaf node.
3. In B tree data may found leaf or non leaf node. Deletion of non leaf node is very complicated. Otherwise in a B+ tree data must found leaf node. So deletion is easy in leaf node.  
4. Insertion of a B tree is more complicated than B+ tree. 
    5.  B +tree store redundant search key but b-tree has no redundant value.
    6. In B+ tree leaf node data are ordered in a sequential linked list but in B tree the leaf node cannot stored using linked list.
Many database system implementers prefer the structural simplicity of a b+ tree.

How to construct a B+ tree with example

Image
A B+ tree contains n-1 search key values K1K2…….Kn-1 and have n pointers.   In a B+ tree the data are ordered  sequentially.  The leaf node may hold up to n pointers and must hold at least N/2 pointers. The root node must hold at least two pointers, unless the tree consists of only one node.  Now we construct a B+ tree. Construct a B+ tree for the following set of key values: (2,3,5,7,11,17,19,23,29,31) Assume that the tree is initially empty and values are added in ascending order. Construct a B+ tree where the pointer number is Four. Solution: When a node exceeds n-1 search key value then we split it into two nodes. First node contains (ceiling(n-1)/2) values.  2 nd node contains remaining node. Copy the smallest search key value of the second node to the parent node. Let's start, we know each node has N pointer and has N-1 search key values. In our example pointer number is 4, so the search key value is 4-1=3. So each node has 4 pointers and 3 search key value. The first node i

How to show only month and year fields in android Date-picker?

Android default DatePicker show day/month/year fields but you have to customize this DatePicker as your requirements. Suppose that you want to show only month and year fields in android datepicker . To do this, you have to customize the Dialog DatePicker source code but it is not an easy task. In this tutorial I will show you a tricky way to solve this problem. Lets see how to show only month and year field in android DatePicker as a dialog.   Step to show only month and year fields in android date-picker: Some days ago I got this same problem and here I am trying to explain this in a sequential manner. I want to show a dialog datepicker when user click on an EditText. So if user click on EditText, A dialog datepicker will be invocked and it will show only month and year fields. To do this, at first we have to create a xml layout to hold the EditText fields. So create an android project and name it DatePickerExample. In the main.xml file just try to write this simple code.  main.xml

Visitor Counter Script Using PHP

Image
If you have noticed that many websites display their total numbers of visitors.In this tutorial I am going to explain you how to create a simple visitor counter using php. For this, 1) Create one table called “visitor_counter” in your database. 2) Create file named “counter.php”. Step1: Creating “visitor_counter” Table CREATE TABLE `visitor_counter` ( `counts` int(10) NOT NULL default '0' ) Step2: Creating “counter.php” File <?php  // Database Details $host="localhost"; $username="root"; $password=""; $db_name="test"; $tbl_name="visitor_counter"; // Connect to server and select database. mysql_connect("$host", "$username", "$password")or die("cannot connect to server "); mysql_select_db("$db_name")or die("cannot select DB");  $sql="SELECT * FROM $tbl_name"; $result=mysql_query($sql); $rows=mysql_fetch_array($result); $counter=$rows['counts']; // se
