What is the Database Management System in SAP?

Posted by thegeek | Posted in Tech | Posted on 09-10-2009

Basically SAP, an enterprise application is made up of programs together with the data used and formed by programs. The data are organized in a meaningful way within the database, making it easy for the programs to access and find the data necessary to do something useful like run a financial report or create a sales order. Both the programs as well as data exist in the same database in the case of an SAP component or products such as ECC. Normally each and every component has its own database a production system landscape composed of SAP ECC, SAP Business Warehouse (BW), and SAP Customer Relationship Management (CRM) consists of three production databases.

Database Structure:

Essentially database is an electronic filing system that houses a collection of information organized in such a way that allows a computer program to find preferred pieces of data in a rapid way. A database is composed of tables, columns (called fields), and rows (called records or data). The fundamental structure of a database is same as the Microsoft Excel spreadsheet wherein columns (fields) store row after row of records (data). The difference between a database and a spreadsheet is simply the databases that contain multiple tables are connected to one another through relationships.

Database structure is an alternative technical term that does not need to concern with you, but are important nonetheless. Structures are triggered and are very well defined in the ABAP/4 Data Dictionary and have only temporary data. The database plays a key role in each SAP system, as it houses all the data that are used by that SAP component or product specifically. Numerous brands of databases exist, making it easier for an IT shop to opt for a database vendor with which they are almost well-known. Moreover, it is imperative to note that not all database vendors and versions are supported by SAP. Rather it tends to stick with the market leaders, over the years adding and removing support for certain vendors.

Primary Key

Database tables in an RDBMS are obligatory to hold a unique field that distinguishes one particular record separately from others found in the database. This unique field is called a primary key and is composed of one or more fields that make each and every record in a database as a unique one.

Foreign Key

Use the primary key field in one table for linking it with another. The common link field in the other table is usually not the primary key in the other table: and is known as a foreign key.

Database Concepts:

The SAP system contains lots of types of constructs along with structures inside the R/3 Data Dictionary (DDIC). The majority of these constructs tend to be very technical.

Transparent Tables

SAP uses another concept called transparent tables, which are SAP database tables that contain only data at runtime. When a table is activated in the ABAP/4 Data Dictionary, a transparent table is created automatically in the database. This transparent table encloses the same name as your database table contained in the ABAP/4 Dictionary. Each of its fields contains the same names as their database counterparts though the sequence of the fields might get varied. This unstable field sequence makes it possible to insert new fields into the table without having to convert it, all of which pays a way for more rapid access to data during runtime.

Using Mobile Phones as Mp3 Players

Posted by thegeek | Posted in Tech | Posted on 09-10-2009

Everyone loves music of some kind and mobile phone shops have seen a remarkable increase in the demand for the mobiles with the music players in the recent years. Cell phones are not limited to only taking calls and a large number of consumers are attracted to the cell phones with sophisticated music players. They are getting bigger and better with each passing year. Sony Ericsson was the mobile manufacturing company which came up with the first mobile phone with the music player. Since then there has been a considerable increase in the number of the music mobile phones and everyday new cell phones are launched in the market with advanced music players.

Before visiting the mobile phone shops and buying a new phone with music player there are certain points which you should always consider. There is no point in buying a music cell phone with a limited capacity. You should always go ahead and check the storage capacity of a cell phone and should buy the one which can help you to store thousands of your favorite tracks. These days music mobile phone shops sell phone that come with a massive storage capacity of anywhere between 1GB and 32GB and beyond. Look for a micro secure digital card slot with high capacity as these are the currently the smallest cards and they are also capable of holding massive amounts of musical data and even videos. Also, the cell phone should have a good memory card and the sound card which will help in enhancing the quality of the sound.

You should also check the volume level of a music phone before buying it since a lot of multimedia phones do not have a good sound quality. Sometimes, because of a cheap sound card, the mobile phones have limited and there is a lack of clarity in the sound. The sound quality can also however depend upon the quality it has been converted at. Another important and interesting feature which is important while going for a music mobile phone is the ability to listen to the FM radio. Most of the consumers prefer listening to the FM radio rather than storing music in the cell phone and listening to it, this is mostly because of the live broadcasts made by radio stations.

Finally, you should be sure and comfortable with getting rid of the music player and buying a music cell phone. With a single music player which comes with a phone, there are certain disadvantages as well. If you are a kind of person who loses the cell phone regularly, accidentally drops the mobile phone on a regular basis, drive over it, put it in a microwave carelessly, then you should not be buying a single device. If you lose your cell phone, you lose your favorite music along with anything else you may have stored in the phones memory. In that case, if you own a music player and cell phone, you will have great chances of saving your favorite tunes.

They sponsor contests – be it an electronic raffle, a creativity-based competition, and the likes – with the winner being awarded the console that the website received for free.

2. Earn easy cash online and buy a Nintendo DSi. There are many ways by which you can make a living on the World Wide Web. Look for a drop shipper and help sell its products in popular outlets like eBay.com and Yahoo Auctions. Create your own digital product and sell it over affiliate networks like ClickBank.com.

3. Join an online gaming store’s affiliate program. Refer customers to the said gaming store. As reward, you can be paid with cash or with store credits. Either way, if you earn enough, you can redeem them for a brand new Nintendo DSi.

As they always say, if there’s a will, there’s way. Don’t let the recession ruin your dreams of owning a Nintendo DSi. With hard work and a little luck, you can be playing the newest Fire Emblem game as soon as next week.
