Recommended: Purposes of the database management system
Technology has become a major part of the today’s society. Most of the information that we see on the internet is derived from databases somewhere in the world. Databases are the key to many things in the world included video rental, libraries, e-commerce, booking a vacation, studying at college and many more. Database administrators and companies often have to make the decision of what database system would best suit their needs. Some important topics to consider are: licensing and cost, user concepts/functions, operating system capability, data partitioning and performance. MS T-SQL, MySQL, and Oracle are amongst the most commonly used database systems.
MS T-SQL is a Microsoft relational database management system (DBMS). Due to the system being a closed source, it does require a license in order to use it. The performance T-SQL is very complex. Quality Web Programming noted in their blog that, a developer would need “sound knowledge and efficient hardware, otherwise it would make the system difficult to work with” (“Using MS SQL and MySQL”). For some companies, this may not be a user friendly system. It would require the company to pay out a higher salary in order to be able to implement and utilize this system. With small businesses or individuals, this just may not be something that they can afford.
MS T-SQL does have user-defined functions. One of these user-defined functions is the ability to have module programming. As discussed in the “User-Defined Functions” article found on technet.microsoft.com, “You can create the function once, store it in the database, and call it any number of times in your program”. Some developers would consider this a big advantage when working with database systems. This allows for faster perfo...

... Ozar stated on his website that, “Standard Edition is $7,499 per processes (socket) [and] Enterprise Edition is $28,749 per processor” (“SQL Server 2008 R2 Pricing and Feature Changes”). The differences with the Enterprise Edition is that the purchaser would receive the support for eight CPUs compared to the four that the standard edition offers. The Enterprise Edition a maximum memory utilization of 2 TB compared to the 64 GB from the standard, and both editions offer a maximum database size of 524 PB. In addition, the Enterprise Edition offers IA64 hardware support, resource governance, and table and index partitioning. There are many other technical differences between the two editions, however they will not be covered in this paper.
Another commonly used database is MySQL. This database system is an Open Source system and is easily accessible to any developer.
The common element of the open source databases is the use of share data of student information. The common features used by the databases are their operating systems UNIX or Windows, as well as MYSQL database. The database used b...
Databases always used to fascinate me from my under graduation with great curiosity to know how large data is managed and queried. This led me to do Masters in computer science concentrating in the field of Data Management. In the course of my study, I understood the concepts of DBMS which provides a robust and efficient way of managing and mining data. Through the courses like Database Systems (ITCS 6160), Knowledge Discovery in Databases(ITCS 6162) and Knowledge Based Systems(ITCS 6155) I gained enough theoretical and practical knowledge about the importance of proper organization of data, good techniques to build an efficient database management system and how well the data can be managed.
In 1991 I performed a thorough evaluation and comparison of the four major DBMSs at the time: Informix, Ingres, Oracle, and Sybase. This comparison was done for a client building a huge distributed database application, currently in its second phase of d evelopment, with the first phase running successfully country-wide. At that stage, the distinguishing criteria were query optimizers, triggers, views, and support for distributed databases. Some products had these features, but some others' marketing per sonnel were just talking about them. For example, declarative integrity was a "future" that was at that stage only being phased into most of the DBMS products. It was relatively straightforward to draw up a checklist and fill it in with "yes" and "no" in the various columns.
Some faculties and departments are already using Oracle applications in their day-to-day operations. As time goes by, more and more information users will be working with an application based on Oracle database technology. If you get the opportunity to be a member of an application development team, you will become familiar with the workings of Oracle and relational databases. Other users may have to learn about this popular database management system through their own experience. This article is for our readers who, as of yet, have no access to Oracle databases but have a yearning for learning what they're all about.
As advance technology of fiber-optic developed and is on the rise, everyday there is another story about entertaining movies on demand and streaming online is with ease. Those developments which let movie’s viewers sit in the comfort of their home or anywhere with access to the internet can stream instance movies with a push of a bottom. They no longer need to make a trip to the movie’s stores for movies rental and return, so that is why movie shops fail and filed for bankruptcy bring a symbolic close to the “let’s go rent a movie” era. Blockbuster LLC, formerly Blockbuster Entertainment Inc., both owned and franchised American-based giant provider of home movie and video game rental services through video rental stores, later adding movies by mail, streaming online and video on demand. Due to the peak of fiber-optic and competition from companies such as Netflix, Redbox, and GameFly, Blockbuster became the victim of digital media and filed for bankruptcy on September 23, 2010 due to significant lost in revenue.[3]
In 1977, Larry Ellison, Bob Miner, and Ed Oates founded System Development Laboratories. After being inspired by a research paper written in 1970 by an IBM researcher titled “A Relational Model of Data for Large Shared Data Banks” they decided to build a new type of database called a relational database system. The original project on the relational database system was for the government (Central Intelligence Agency) and was dubbed ‘Oracle.’ They thought this would be appropriate because the meaning of Oracle is source of wisdom.
DBA deals with all of this by finding user needs, set the database, and test the system. DBA should enable editing any system he or she created. At the same time DBA should ensure the security of the data and guarantee data integrity and backup. Moreover, DBAs should know the database management systems (DBMS) that include the knowledge of Oracle, IBM DB2, and Microsoft SQL server (“Database Administrator,” 2010). Oracle is one of the most important platforms that DBA must know and have experience with. According to Kanaracus “The database experience we look for most of the time is Oracle”, says Tom Hart, executive vice president of the operations and technology group at Veritude. “SQL Server is more of a nice-to-have"

When you think about, it shouldn’t a business have the same kind of single point of control? Enterprise Resource Planning Software provides the level of oversight and control that is absolutely necessary for you, as a manager or owner, to make sure that all of your resources are all working towards the same goal. The hard part is choosing an ERP system that works for your company. No two manufacturers run exactly the same way, and similarly no two ERP systems run exactly the same way. So it’s important to research the product and the vendor to make certain that you select the right system for your business. You’ve got to have a system that fully integrates all aspects of running your manufacturing business, offers advanced features and options but is intuitive and easy to use so employees can grasp hold quickly, and adapts to the way you do business rather than forcing you to adapt to the software.
In the past, most of the databases were centralized, protected, and kept in a one location using a complicated database system known as centralized database. Nowadays, with the new technology of personal computers and cell phones, a new sort of database has appeared, and it seems that majority of people are pleasant with it, even if their private data is split everywhere. Many enterprises had changed their databases from the centralized databases, into the distributed database system, since it meets the demand of accessing and processing the data in the organization. Distributed database technology is considered as one of the most remarkable developments in this century (Ozsu, 1991; Rahimi & Haug, 2010; Cain, 2012). Distributed databases are basically a collection of databases that are divided on multiple computers which are connected logically but located in different physical locations, and each site manages its own local data. In contrast, centralized database is a database that is located in a one location and it is considered as a big single database (Connolly & Begg, 2010).
Many organization have developed and adopted ERP system and most of them do not have the exact idea of the total cost, everytime when a new organization has to be setup the question arises “How much is the total cost of ERP system ? “ this question can only be answered by careful assessment of the requirements because the cost of ERP system depends on the complexity of implementation and demand and needs of the organistion.Furthermore it also depends on whether new ERP system has to be purchased as a whole with hardware or the organsation will continue to use the old infrastructure.ERP systems are charged on a user basis depending on how many users are going to use the system which can be somewhere around $ 1500 to 4000$ per member.The number of user relates directly with the cost for instance if we talk about small to medium business they sometimes do not require Master Production Scheduling Module or some different complex tools which is at the same time required by big multinational company for more accuracy and flexibility It is said that as the number of users increases it results in the decreasing the total cost furthermore the implementation costs would increase as the degree of customization increases
System performance is one of the most critical issues faced by companies dealing with vast amounts of data. Companies use database systems and their applications to store, retrieve and handle this data.
In order to access information from a database, it is required to have a database management system (DBMS). These systems are computer software applications that, in order to analyze the data, interact with the user and the database itself. The best known are [6]:
A database comprises an information of data for producing quicker and accessed, maintained, and renewed data. The database software its storage to retain and combine data that I deal with every day. To illustrate, a data information as personal data that connected to users ' information. The database continues to be critical for organizations that keep them in the business. A database is a large number of data that I work carefully with in every database of the organization. In other words, by Computer information system, I understand database, it is my job to deliver them to correct the
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
