...9/11/15 Role in the Database Environment A database management system is the software system that allows users to define, create and maintain a database and provides controlled access to the data. A Database Management System (DBMS) is basically a collection of programs that enables users to store, modify, and extract information from a database as per the requirements. DBMS is an intermediate layer between programs and the data. Programs access the DBMS, which then accesses the data. There are different types of DBMS ranging from small systems that run on personal computers to huge systems that run on mainframes. There are a lot of database software manufacturers out there and a wide range of prices, sizes, speeds and functionalities. At the lower end of the scale are personal database software products like Microsoft Access, which is designed to be used by individuals or small companies relatively little data. User friendliness and ease of use are the priority rather than speed and scalability (in other words, it works well when you have 100 records but not when you have 100,000). At the higher end are full-fledged enterprise solutions, such as Oracle Enterprise Edition. These database software products can handle millions of data entries and are fast and efficient. They have ·many optimization and performance tools and generally require a Database Administrator (DBA) to look after them. Products in this range can also be very expensive. In file system, each application has...

...Web 407 Week 3 Database Paper In the business world, most people will find a need for a database software program to store or house data pertaining to their business. There are however, multiple things to consider before one makes their final choice on what software they will be using. A few things that should be addressed are the type of software desired, either open-source or propriety, and what characteristics of the database meets the company’s needs. There are two basic types of database programs people can choose from when deciding what they want for their small business, an open-source database or a propriety one. While both of these are similar, they still have their advantages and disadvantages. First, consider what an open-source program is. The term open-source means exactly what it sounds like; the source code for the software is completely open and free to the public. Some advantages that come with this are the fact there is no upfront costs when it comes to obtaining the database program. While this sounds great, one needs to consider the tools the business has at its disposal. If you do not have the people to manage the databases and run them, then more employees must be hired in order to support the system. This can lead to more cost in the long run. So the fact that it’s free can also be a disadvantage. Another advantage to open-source database systems is a lot of them have a huge following such as MYSQL. MYSQL is database that is designed to use Standard...

When it comes to a database management system is a collection of software packages designed to store, access and manage databases. Databases are used across the health care industry to able to store patient’s files because the databases are used to store data over a long period of time. In addition it helps organizations have file access to patients file and being able to check the status or enter patients information and sure it with different organizations. When it comes to health care database systems there are four different structural types of database management systems and they are hierarchical databases, network databases, relational databases, and object-oriented databases. Hierarchical database is commonly used on the mainframe computers; this is also the oldest method being used by organizing and storing data, by organizations. This structure follows the pyramid fashion. This means that related fields are grouped together which includes higher-level records and lower-level records. When using this structure there are advantages and disadvantages that go along with this method. The advantages are files can be accessed and...

...After a brief research of the latest versions of the following database management systems (DBMSs) on the market: Oracle 11G, Microsoft SQL Server, MySQL, and IBM DB2. I found the following information about each DBMS’s. Oracle 11G The biggest advantage Oracle 11G has is that it can help you create customized database applications. Instead of getting a standardized database program out of the box, you get a program that can be customized to fit your needs. This makes it possible to create a database that only has the features you need. Another advantage is Data Mining. It makes it possible to find relationships in data that would otherwise be difficult to find on your own. As good as the above sounds it also comes with a couple of BIG disadvantages. The biggest would be the cost, if you plan on using the program on multiple computers, you will need to buy licenses for each computer. If you plan on making the software available on many computers, these costs can really add up. Another big disadvantage is it comes with a learning curve; this is not something that you can pick up in a short period of time. Microsoft SQL Server MS SQL Server is a Client-server relational database system, with no UI development tools built in. Some of it advantages are, Maintenance its has lots of tools for maintenance, can do most of it with users in DB. It is user friendly, great security, it minimizes redundancy, and it is very consistent. It also works great on an enterprise scale it is designed...

...reading. This well occupied library has been through a renovation lately where there is more reading space and also more books. The college library management has been done manually and not computerised. They have opened suggestions to the student where they can give out suggestion on which hardware and software can be used for our college library. As most of the library in colleges and public library tend to use computerised system for the management purpose has been making things easy and effective for the librarian to do their job. The type of hardware that I would suggest that would be fundamental for a library system would be definitely the system unit, the monitor, the keyboard, the mouse and a printer. A system unit with a business user specification would be prefect for this usage. In detail, Server or PC with i5 Processor, Windows 7, a 500 GB hard drive, 4 GB of fast DDR3 RAM memory, and a LCD display. Hardware which would be even necessary would be like the finger print reader where this can used to scan and read finger print of students who want to borrow books just have to place their finger to be scanned as their details and data would appear in the monitor’s screen of the librarian. This would be necessary as scanning wouldn’t take a very long time and its even precise compared to filing data manually. The only disadvantage of using the deivce would be where if the if the finger is dirty or injured the reader cant read its print. A smart card reader would also do...

The requirements to build a database design for scheduling are tables, records, primary key relationship that will make up the database. The database is a relational one as defined by the primary key. The advantages of moving this scheduling to database is reduction in data redundancy, decreases in updating errors and increased consistency along with greater data integrity. Lat but not least I will discuss the ethical issue of change over to an automate system. I have created a graph of the database along with an access database. .

...Comparison of Traditional File-Based Approach and Database Approach At the beginning, you should understand the rationale of replacing the traditional file-based system with the database system. File-based System File-based systems were an early attempt to computerize the manual filing system. File-based system is a collection of application programs that perform services for the end-users. Each program defines and manages its data. However, five types of problem are occurred in using the file-based approach: Separation and isolation of data When data is isolated in separate files, it is more difficult for us to access data that should be available. The application programmer is required to synchronize the processing of two or more files to ensure the correct data is extracted. Duplication of data When employing the decentralized file-based approach, the uncontrolled duplication of data is occurred. Uncontrolled duplication of data is undesirable because: i. Duplication is wasteful ii. Duplication can lead to loss of data integrity Data dependence Using file-based system, the physical structure and storage of the data files and records are defined in the application program code. This characteristic is known as program-data dependence. Making changes to an existing structure are rather difficult and will lead to a modification of program. Such maintenance activities are time-consuming and subject to error. Incompatible file formats ...
