Android Design Pattern
The Android platform provides a common set of design patterns, and with the limited hardware resources you get compared to Web-apps it is still often best to stick with using these directly in production code. There are other frameworks that sort of "wrap" the base platform; these are worth looking into if you have a specific purpose (or perhaps for prototyping/experimenting), but for the best level of support you are generally best sticking with the standard components. <br /> <br /> <br />

Lesson 21 Delete data from dat ...
<u><strong>Lesson 21: Delete data from database</strong></u><br /> <br /> In the two previous lessons, you have learned to insert and retrieve data from a database. In this lesson, we'll look at how to delete records in the database, which is considerably easier than inserting data.<br /> <br /> <em><strong>Delete data using SQL</strong></em><br /> <br /> The syntax for an SQL statement that deletes records is:<br /> <br /> <br /> DELETE FROM TableName WHERE condition<br /> <br /> <br /> <u><strong>Example: Delete a record</strong></u><br /> <br /> When deleting a record, you can use the unique AutoNumber field in the database. In our database, it is the column named id. Using this unique identifier ensures that you only delete one record. In the next example, we delete the record where id has the value 24:<br /> <br /> <br /> <html><br /> <head><br /> <title>Delete data in the database</title><br /> </head><br /> <br /> <body><br /> <br /> <?php<br /> // Connect to database server<br /> mysql_connect("mysql.myhost.com", "user", "sesame") or die (mysql_error ());<br /> <br /> // Select database<br /> mysql_select_db("mydatabase") or die(mysql_error());<br /> <br /> // The SQL statement that deletes the record<br /> $strSQL = "DELETE FROM people WHERE id = 24";<br /> mysql_query($strSQL);<br /> <br /> // Close the database connection<br /> mysql_close();<br /> ?><br /> <br /> <h1>Record is deleted!</h1><br /> <br /> </body><br /> </html><br /> <br /> <br /> Remember that there is no "Recycle Bin" when working with databases and PHP. Once you have deleted a record, it is gone and cannot be restored.<br />

Lesson 22 Update data in a dat ...
<u><strong>Lesson 22: Update data in a database</strong></u><br /> <br /> In previous lessons, you have learned to insert, retrieve and delete data from a database. In this lesson, we will look at how to update a database, i.e., edit the values of existing fields in the table.<br /> <br /> <em><strong>Update data with SQL</strong></em><br /> <br /> The syntax for an SQL statement that updates the fields in a table is:<br /> <br /> <br /> UPDATE TableName SET TableColumn='value' WHERE condition<br /> <br /> <br /> It is also possible to update multiple cells at once using the same SQL statement:<br /> <br /> <br /> UPDATE TableName SET TableColumn1='value1', TableColumn2='value2' WHERE condition<br /> <br /> <br /> With the knowledge you now have from the lessons 19, 20 and 21, it should be quite easy to understand how the above syntax is used in practice. But we will of course look at an example.<br /> <br /> <em><strong>Example: Update cells in the table "people"</strong></em><br /> <br /> The code below updates Donald Duck's first name to D. and changes the phone number to 44444444. The other information (last name and birthdate) are not changed. You can try to change the other people's data by writing your own SQL statements.<br /> <br /> <br /> <html><br /> <head><br /> <title>Update data in database</title><br /> <br /> </head><br /> <body><br /> <br /> <?php<br /> // Connect to database server<br /> mysql_connect("mysql.myhost.com", "user", "sesame") or die (mysql_error ());<br /> <br /> // Select database<br /> mysql_select_db("mydatabase") or die(mysql_error());<br /> <br /> // The SQL statement is built<br /> $strSQL = "Update people set ";<br /> $strSQL = $strSQL . "FirstName= 'D.', ";<br /> $strSQL = $strSQL . "Phone= '44444444' ";<br /> <br /> $strSQL = $strSQL . "Where id = 22";<br /> <br /> // The SQL statement is executed<br /> mysql_query($strSQL);<br /> <br /> // Close the database connection<br /> mysql_close();<br /> ?><br /> <br /> <h1>The database is updated!</h1><br /> </body><br /> </html><br /> <br /> <br /> This example completes the lessons on databases. You have learned to insert, retrieve, delete and update a database with PHP. Thus, you are actually now able to make very advanced and dynamic web solutions, where the users can maintain and update a database using forms.<br /> <br /> If you want to see a sophisticated example of what can be made with PHP and databases, try to join our community. It's free and takes approximately one minute to sign up. You can, among other things, maintain your own profile using the form fields. Maybe you will get ideas for your own site.<br /> <br /> This also ends the tutorial. PHP gives you many possibilities for adding interactivity to your web site. The only limit is your imagination - have fun!<br />

PHP array functions
The array functions allow you to manipulate arrays.<br /> <br /> PHP supports both simple and multi-dimensional arrays. There are also specific functions for populating arrays from database queries.<br /> <br /> These functions allow you to interact with and manipulate arrays in various ways. Arrays are essential for storing, managing, and operating on sets of variables.<br /> <br /> Simple and multi-dimensional arrays are supported, and may be either user created or created by another function. There are specific database handling functions for populating arrays from database queries, and several functions return arrays.<br /> <br /> <strong>For detailed explanation read the attached document.</strong>

Storage and File Structure
Database tables/indexes are typically stored on hard disk in one of many forms, ordered/unordered Flat files, ISAM, Heaps, Hash buckets or B+ Trees. These have various advantages and disadvantages discussed in this topic. The most commonly used are B+trees and ISAM.<br /> <br /> <u><strong>Storage and File Structure</strong></u><br /> <br /> We have been looking mostly at the higher-level models of a database. At the conceptual or logical level the database was viewed as<br /> A collection of tables (relational model).<br /> A collection of classes of objects (object-oriented model).<br /> The logical model is the correct level for database users to focus on. However, performance depends on the efficiency of the data structures used to represent data in the database, and on the efficiency of operations on these data structures.<br /> <br /> <em><strong>For detailed explanation read the attached document.</strong></em>

Query Processing
<em><strong>What Is a Query Processor?</strong></em><br /> <br /> A relational database consists of many parts, but at its heart are two major components: the storage engine and the query processor. The storage engine writes data to and reads data from the disk. It manages records, controls concurrency, and maintains log files.<br /> <br /> The query processor accepts SQL syntax, selects a plan for executing the syntax, and then executes the chosen plan. The user or program interacts with the query processor, and the query processor in turn interacts with the storage engine. The query processor isolates the user from the details of execution: The user specifies the result, and the query processor determines how this result is obtained.<br /> <br /> <br /> <br /> <em><strong>For detailed explanation read the attached document.</strong></em>

Face to face interview
<strong>Whether you're looking for your first job or your fifth, you're after an entry level sales position or top management spot, there are some universal rules to successful interviewing. An interview is not a two way street! It is your job to sell yourself with a positive attitude and enthusiasm. Regardless of your initial impression of the job opportunity, your main objective is to obtain a JOB OFFER by outshining the competition. It is impossible to properly evaluate a position before a bona fide offer has been extended. Preparation for an interview should be a serious matter. Interviewers are looking at you not only as a candidate but as a performer in their organization.</strong><br /> <br /> <strong>For More details click the attachment below.</strong>

Tips for Appearance on the day of Interview
<strong>Your appearance is probably one of the most important aspects when first impressions are concerned. Ever heard the saying “A picture is worth a thousand words”? The same can be said for your appearance at a job interview. Turn up dressed in dirty, unironed clothing to an interview for an executive position, then no matter how well you perform during that interview, your appearance may be the reason they turn you down.<br /> Also, ensure your appearance isn’t too distracting. For example, if you wear nail polish, ensure it’s not chipped. Don’t wear loud ties, or excessive amounts of jewelry. Ensure your makeup isn’t too heavy and make sure your hair is washed and not flopping into your eyes so you have to keep pushing it back.<br /> <br /> For more details read the attached document.</strong>

Speed: One of the major disadvantage of the public-key encryption is that it is slower than secret-key encryption. In secret key encryption, a single shared key is used to encrypt and decrypt the message which speeds up the process while in public key encryption, different two keys are used, both related to each other by a complex mathematical process. Therefore, we can say that encryption and decryption take more time in public key encryption. Authentication: A public key encryption does not have a built-in authentication. Without authentication, the message can be interpreted or intercepted without the user's knowledge. Inefficient: The main disadvantage of the public key is its complexity. If we want the method to be effective, large numbers are needed. But in public key encryption, converting the plaintext into ciphertext using long keys takes a lot of time. Therefore, the public key encryption algorithms are efficient for short messages not for long messages.

The main restriction of private key encryption is the sharing of a secret key. A third party cannot use this key. In public key encryption, each entity creates a pair of keys, and they keep the private one and distribute the public key. The number of keys in public key encryption is reduced tremendously. For example, for one million users to communicate, only two million keys are required, not a half-billion keys as in the case of secret key encryption.

<u><strong>Windows XP</strong></u><br /> <br /> The Windows eXPerience operating system is available as home and professional edition and are similar suitable for the use on standalone computers. The home edition is suitable for user which worked with Windows 9x/ME till now and don't need special network or security features in theire environment. If the user have used Windows NT/2000 private, in business or both, the Professional Edition is not only with a view of the administration optimally. Microsoft already encloses 10,000 drivers on the installation media of Windows XP, about the Windows update further more 2,000 drivers are available.<br /> <br /> The Professional Edition of Windows XP has more network features than the Home Edition. An update of Windows 9 x/ME is possible, with Windows NT/2000 only the Professional Edition can be used for update. Optional FAT32 and NTFS are available as a file system for the installation partition.<br /> <br /> Windows XP (Windows version 5.1) becomes a predecessor of Windows 9x/ME as well as Windows NT/2000 and is available for 32-bits CPUs in the following versions:<br /> <br /> - Embedded<br /> - Home Edition (1 CPU) for private user (Oct. 2001)<br /> - Professional Edition (2 CPU) for business user (Oct. 2001)<br /> - Media Center (1 CPU) especially for multimedia devices (Nov. 2002)<br /> - Tablet PC Edition especially for Tablet PCs (Nov. 2002)<br /> - Server Edition (4 CPU)<br /> - Advanced Server (8 CPU), also 64-bit Intel CPUs<br /> - Microsoft Windows Fundamentals for Legacy PCs (July 2007)<br /> <br /> A 64-bit version of Windows XP was announced officially of Microsoft in April 2003.

File System Implementation not ...
<u><strong>File System Implementation</strong></u><br /> <br /> Discuss several file system implementation strategies.<br /> <br /> First implementation strategy: contiguous allocation. Just lay out the file in contiguous disk blocks. Used in VM/CMS - an old IBM interactive system.<br /> Advantages:<br /> Quick and easy calculation of block holding data - just offset from start of file!<br /> For sequential access, almost no seeks required.<br /> Even direct access is fast - just seek and read. Only one disk access.<br /> <br /> Disadvantages:<br /> Where is best place to put a new file?<br /> Problems when file gets bigger - may have to move whole file!!<br /> External Fragmentation.<br /> Compaction may be required, and it can be very expensive.<br /> <br /> Next strategy: linked allocation. All files stored in fixed size blocks. Link together adjacent blocks like a linked list.<br /> <br /> Advantages:<br /> No more variable-sized file allocation problems. Everything takes place in fixed-size chunks, which makes memory allocation a lot easier.<br /> No more external fragmentation.<br /> No need to compact or relocate files.<br /> <br /> Disadvantages:<br /> Potentially terrible performance for direct access files - have to follow pointers from one disk block to the next!<br /> Even sequential access is less efficient than for contiguous files because may generate long seeks between blocks.<br /> Reliability -if lose one pointer, have big problems.<br /> <br /> FAT allocation. Instead of storing next file pointer in each block, have a table of next pointers indexed by disk block. Still have to linearly traverse next pointers, but at least don't have to go to disk for each of them. Can just cache the FAT table and do traverse all in memory. MS/DOS and OS/2 use this scheme.<br />

File System Interface notes fo ...
<u><strong>File System Interface</strong></u><br /> <br /> A frequent use of streams is to communicate with a file system to which groups of data (files) can be written and from which files can be retrieved.<br /> <br /> Common Lisp defines a standard interface for dealing with such a file system. This interface is designed to be simple and general enough to accommodate the facilities provided by ``typical'' operating system environments within which Common Lisp is likely to be implemented. The goal is to make Common Lisp programs that perform only simple operations on files reasonably portable.<br /> <br /> To this end Common Lisp assumes that files are named that given a name one can construct a stream connected to a file of that name and that the names can be fit into a certain canonical implementation-independent form called a pathname.<br /> <br /> Facilities are provided for manipulating pathnames for creating streams connected to files and for manipulating the file system through pathnames and streams.<br />

12 Codd Rules
Codd's twelve rules are a set of thirteen rules (numbered zero to twelve) proposed by Edgar F. Codd, a pioneer of the relational model for databases, designed to define what is required from a database management system in order for it to be considered relational, i.e., a relational database management system (RDBMS).[1][2] They are sometimes jokingly referred to as "Codd's Twelve Commandments".<br /> Codd produced these rules as part of a personal campaign to prevent his vision of the relational database being diluted, as database vendors scrambled in the early 1980s to repackage existing products with a relational veneer. Rule 12 was particularly designed to counter such a positioning.<br /> Even if such repackaged non-relational products eventually gave way to SQL DBMSs, no popular "relational" DBMSs are actually relational, be it by Codd’s twelve rules or by the more formal definitions in his papers, in his books or in succeeding works in the academia or by its coworkers and successors, Christopher J. Date, Hugh Darwen, David McGoveran and Fabian Pascal. Only less known DBMSs, most of them academic, strive to comply. The only commercial example, as of December 2010, is Dataphor.<br /> Some rules are controversial, specially rule three, due to the debate on three-valued logic.<br /> <br /> <strong>For further information read the attached document....</strong>

Overview of Oracle
An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data. All this is accomplished while delivering high performance. A database server also prevents unauthorized access and provides efficient solutions for failure recovery.<br /> <br /> Oracle Database is the first database designed for enterprise grid computing, the most flexible and cost effective way to manage information and applications. Enterprise grid computing creates large pools of industry-standard, modular storage and servers. With this architecture, each new system can be rapidly provisioned from the pool of components. There is no need for peak workloads, because capacity can be easily added or reallocated from the resource pools as needed.<br /> <br /> The database has logical structures and physical structures. Because the physical and logical structures are separate, the physical storage of data can be managed without affecting the access to logical storage structures.<br /> <br /> <strong>For further information read the attached document....</strong>
