QUESTION 1
Differentiate between database management system and information retrieval system by focusing on their functionalities.
Database Management Systems or in short form called DBMS is the major component in most of the information systems. DBMS is the basic system been used in the information system. Or in the other name, DBMS is the traditional way. The Information Retrieval System or IRS is the extended function from the DBMS thus we can explain it here that IRS is came from the DBMS. There will be some differences between Database Management System and Information Retrieval System in the functionalities and uses.
There are three types of Database Management System which are the relational Database Management System, the non-relational Database Management System and Object Oriented Database Management System. The relational DBMS is the most widely accepted Database Management System nowadays. The non-relational DBMS that are in large scale are still in use while the Object Oriented DBMSs are in development. Besides, more and more DBMSs are supporting basic multimedia storage and retrieval facilities.
Information retrieval system is the most advance system and facilities as it is usually use for accessing large document and text databases. According to Hoogeveen, M.J., & Van der Meer, K. in their journal name Integration of Information Retrieval and Database Management in Support of Multimedia Police Work written in 1994 stated that Information Retrieval System or IRS is the most exclusive domain of Information storage and Retrieval Systems.
Y.Y. Yao in the journal Information Retrieval Support Systems stated that Information Retrieval System or IRS in short is different with Database Management Systems. The Information...

...ctured data and extract the essential information. These can include hardware or software solutions that enable them to make the most efficient use of their available storage space. The main benefit of these tools is the ability of the system to gather actionable information that can and will help a business to succeed in a competitive environment.

The first database systems were based on the network and hierarchical models. A database can be defined as a collection of non-redundant data which can be shared by different application systems. A database implies separation of physical storage from use of the data by an application program to achieve program/data independence. Using a database system, the user or programmer or application specialist need not know the details of how the data are stored and such details are usually "transparent" to the user. .
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.
This paper will compare and contrast five different database management systems on six criteria. The database management systems (DBMS) that will be discussed are SQL Server 2000, Access, MySQL, DB2, and Oracle. The criteria that will be compared are the systems’ functionality, the requirements that must be met to run the DBMS, the expansion capabilities – if it is able to expand to handle more data over time, the types of companies that typically use each one, the normal usage of the DBMS, and the costs associated with implementing the DBMS.
The construction of Object-Oriented Database Management Systems started in the middle 80's, at a prototype building level, and at the beginning of the 90's the first commercial systems appeared. The interest for the development of such systems stems from the need to cover the modeling deficiencies of their predecessors, that is the relational database management systems. They were intended to be used by applications that have to handle big and complex data such as Computer Aided Engineering, Computer Aided Design, and Office Information Systems.
In one of the big company, Informatica is that data integration software and services to the organisation that enable to get the advantage to compete with others. They basically based on the metadata to run the company. Furthermore, SAS, is the company that helps organisation anticipate business opportunities, empower action and drive impact. They create and manage the metadata and define access to control and manage users through a single environment. By doing this, a number of metadata are provided to import and export the metadata from a variety of sources. They also track change history to find out who made changes and when the changes took place. As the metadata stand for finding information easily, they create data items with descriptive labels to organise data items into folder and subfolder for users to find the informations. By creating table aliases to provide additional flexibility required for proper query generations, and they create predefined filter expressions so users can choose the appropriate result subset, creating prompted filters so users can dynamically select filter values when creati...
As the conclusion, the paper made good contribution to the field by describing the history of the information retrieval systems from 1945 to 1996 with abundant information on the various technologies developed, information retrieval systems built, and how they affected the research in information retrieval. I think artificial intelligence will start to play a leading role in information retrieval in the following years and one day we will have true question answering type of information retrieval at the finger tip of every Internet user.
There are many different types of databases, different performances of databases, and different database software functions. Before we get to much into databases lets take a step back and think about what a database really is and how they are applied. A database is a software program arranged to collect hold and process information. There are quite a bit of software programs out there already that can allow you to do all this. However, what makes databases different is that once you enter information in to, the database will operate the information in ways that allow you to analyze the information. Databases are designed in such a way that as to make it easier to obtain particular pieces of data. Databases are used in many ways existing in pretty much the entire world of computers. Databases are the most used method of storage for large multiuser funtions where the coordination between many users is necessary. This is just basically what a database is.
Databases are used on a daily basis amongst nearly every industry in the world. Regardless of what job function you currently work you can expect that the data you are using or inputting is coming from or being stored in some type of database. To understand databases you may want to consider how they impact your career, if they are consider enterprise tools, how they are designed and the effort required to do so, and the database architecture.
A database management system, or DBMS, gives the user access to their data and helps them transform the data into information. Such database management systems include dBase, Paradox, IMS, and Oracle. These systems allow users to create, update, and extract information from their databases. Compared to a manual filing system, the biggest advantages to a computerized database system are speed, accuracy, and accessibility.
According to Modern Database Management eight edition, by Jeffrey A. Hoffer, Mary B. Prescott and Fred R. McFadden database management system (DBMS) is define as a software system that is used to create, maintain, and provide controlled access to user databases.
In 1960, Charles Bachman developed the first database management system (DBMS) which two key data models arose: the network model (developed by CODASYL) followed by the hierarchical model (as implemented in IMS). These were later usurped by the relational model, which was contemporary with the so-called flat model designed for very small tasks. Another contemporary of the relational model is the object-oriented database (OODB).
Information Retrieval (IR) is to represent, retrieve from storage and organise the information. The information should be easily access. User will be more interested with easy access information. Information retrieval process is the skills of searching for documents, for information within documents and for metadata about documents, as well as that of searching relational databases and the World Wide Web. According to (Shing Ping Tucker, 2008), E-commerce is rapidly a growing segment in the internet.
It is nothing but saving the gathered data for standard purpose in the computer. The usage of database system in a company does not provide gain rather provides raise in
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.
Database Management System is a database program. It is software designed to assist in maintaining and using the collection of data, and the need for the system, and also use them, is growing rapidly. DBMS contains information about a particular enterprise and provides an environment that is both convenient and efficient to use. The DBMS manages incoming data, organizes, and provides a way for data to be modified or extracted by users or other programs.
