The Difference Between

Replication is the process of propagating changes from one database to other database.

Caching is the process of prefetching the frequently accessed data and storing it in close to the application.

STORED PROCEDURE :

A stored procedure can be created with no parameters, IN parameters, OUT parameters, or IN/OUT parameters.There can be many parameters per stored procedure.

It is also called as a FUNCTION.

EXAMPLE:

1.

-- Hello World in Oracle PL/SQL (stored procedure)

SET SERVEROUTPUT ON

BEGIN

dbms_output.enable(10000); dbms_output.put_line('Hello World');

END;/

OUTPUT : Hello World

2.

SET SERVEROUTPUT ON

BEGINDBMS_OUTPUT.ENABLE;DBMS_OUTPUT.PUT_LINE('Hello World');END;/

SET SERVEROUTPUT OFF

3.

DECLARE

annapurna VARCHAR2(20) := &'annapurna'; -- variable with a value assignment HOURLY_WAGE NUMBER := 5.15; -- until congress changes it HOURLY_WAGE NUMBER DEFAULT 5.15; --using defaultHOURLY_WAGE NUMBER NOT NULL := 5.15; --using not null -- default n not null both r having same functionality -- but, not null requires a valueBEGINDBMS_OUTPUT.PUT_LINE('Hello ' annapurna '!!!');END;/

4.SET SERVER OUTPUT ON

BEGIN DBMS_OUTPUT.ENABLE; DBMS_OUTPUT.PUT_LINE('hello miSS'); END;/

5.

-- calling of a PL/SQL function

SET SERVEROUTPUT ON SIZE 1000000

DECLARE msg VARCHAR2(30);BEGIN msg := message_for_the_world; DBMS_OUTPUT.PUT_LINE(msg);END;/

6.

-- a simple PL/SQL function to return a string

CREATE OR REPLACE FUNCTION message_for_the_worldRETURN VARCHAR2ASBEGIN RETURN 'hello, world';END;/

TRIGGER :

Ii is a fragment of code that tells Oracle to fire or run BEFORE or AFTER a table is modified.

ADVANTAGE : It has the power to make sure that a column is filled in with default information make sure that an audit row is inserted into another table after finding that the new information is inconsistent with other stuff in the database.

Example :

1.

create table my_trigger ( comment_id integer primary key, on_what_id integer not null, on_which_table varchar(50), user_id not null references users, comment_date date not null, ip_address varchar(50) not null, modified_date date not null, content clob, html_p char(1) default 'f' check(html_p in ('t','f')), approved_p char(1) default 't' check(approved_p in ('t','f')));/

2.

Banks Transactions , updations and ONLINE SHOPPING MALLS BUSINESS transactions are the best Examples for TRIGGERS.

One more thing according to my knowledge we write the TRIGGERS in STORED PROCEDURES.

Hello there, i have the creative zen v plus exactly the same really apart from video/photos. Its a great mp3 player with great sound quality and voice record etc. and the battery life is really good. if i was going to buy another mp3 player i would rather buy a creative than an ipod :D George

As with ports, the gender of a connector is determined by whether or not it has pins. For example, a D-sub connector is male if it has pins (i.e. a VGA connector), whereas a serial connector is female (a serial port on the motherboard is male [it has pins to receive the connector], and the connector has the holes in which the pins are inserted).

There is a reason they refer to the meeting of male and female plugs "mating"! Don't think of it as what's being plugged in and what's receiving the plug, but rather whether or not the connector and ports have pins or holes to receive the pins.

Hi,

The difference can be highlighted by defining the two entities separately,

OLTP: Online Transaction Processing is a system normally used in the regular routine of database or User end Transactions (These Transactions are short Transactions).

In OLTP, the data is fully normalized in order to avoid redundancy,Duplication of data etc, for achieving normalization various Joins are used that connects the tables. (without these joins OLTP cannot be fully Normalized).

Now move on,

OLAP: Online Analytical Processing is a system helpful for analysis purposes, it is used in Business Intelligence for analysis reporting, unlike OLTP it doesn't have too many joins in it because in OLAP it is not required to normalize the data, the basic purpose is to make Facts and Dimensions.

<<Specifically for reporting purposes the data retrieval should be faster (The joins make the data processing slow) so the basic need of designing OLAP is to make the reporting system faster.>>

Blogging: you can create large pieces of writing and include pictures, video, audio etc all in the one entry.

Twitter: each tweet is only 140 characters and so you're sending quick messages on what you're upto at that moment, rather than a "diary entry" like you might do on a blog.

That's why, tweeting is referred to a "Micro Blogging" & you can use it to display video/audio/images by including a link inside your tweet.

Twitter offers a URL shortner and there are plenty of them out there to help you make the most out the 140-char limit.

In the Narrow-band channel the signal see the channel as a flat channel , and the signal pass the channel without any type of cut .

In the other hand the signal that passes through the wide-band channel see the channel as a frequency selective channel and cut values from the signal .

I mean that if the bandwidth for the signal is lager than the bandwidth for the channel then, the channel is a wide-band channel, and if the bandwidth for the signal is smaller than the bandwidth for the channel then the channel will be a narrow-band channel .

Basically, VPN deals with security and connecting nodes in a private network across a public IP internet work. Read RFC 1853 - IP Tunneling. You can take one physical LAN and split it into multiple virtual LANs, or you can take multiple physical LANs and integrate them into a VLAN. RFC 0824 is good reading.

Tally is a complete business accounting and inventory management software that provides various facilities like Govt. supported formats, multilingual operations, online functions and processing for small and medium businesses.

Excel - It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications. It has been a very widely applied spreadsheet for these platforms.

A web page is the basic thing you see on the World Wide Web. Each time the URL changes, the web page changes. Multiple web pages grouped together form a website. A web server is what stores websites and delivers them to a web browser when it is requested.

A normal key is when you type on a keyboard or cell phone a letter or number and that is what shows on the screen. For example you type a X you see a X, you type a 9 you see a 9. The keys function is only to produce that letter or number. A soft key is keys on a keyboard or cell phone will preform multiple functions. Like the function keys or 'F-Keys'. These keys can be programmed to do more than one task at a time. Or on a cell phone you can hit the number 3 and a 3 will show on the screen or if you hold the 3 key for a moment it will call a programmed phone number.

The differences are many, but one major difference is the fact that most skilled hackers can make their own backdoor programs, where as an unskilled hacker, AKA a 'script kiddie' needs to rely on programs that they find online.

Also, from a psychological perspective, most skilled hackers are very good at not being found while they are inside a system, because they don't want to be found, and they know what they are looking for. A script kiddie, on the other hand, do not know how to cover their tracks, and most of them probably don't care. They just think it's cool to get inside a system and look around.

Skilled hackers have a goal, where as most unskilled hackers do not.

Minimum mode in the 8086/8088 provides the functionality of the 8288 bus controller, which means that functions like HOLD, HLDA, WR-, M/IO-, DT/R-, DEN-, ALE, and INTA- come off of the 8086/8088.

Maximum mode means that these functions come off of the 8288, in somewhat enhanced form, and the pins are replaced with new meanings like RQ-/GT0-, RG-/GT1-, LOCK-, S2-, S1-, S0-, QS2, and S21, giving the processor extra capabilities.

Means you are afraid of having your picture taken.
