Differentiate between database management system and information retrieval system by focusing on their functionalities.
A database management system in the main software tool of the database management approach because it controls the creation, maintenance, and use of the database of an organization and its users. The three major functions of a database management system are first to create new database and database application. Second to maintain the quality of the data in an organized database. And last to use the database of an organization to provide the information that its end users need. An example of a database management approach in a banking information system. Note how the savings, checking and installment loan programs use a database management system to share a customer database. Note also that the database management system allows a user to make direct, ad hoc interrogations of the database without using application programs.
An information retrieval system (IRS) is the activity of obtaining information resources relevant to an information need for a collection of information resources. Searches can be based on metadata or on full text (or content based) indexing. The automated information retrieval system is used to reduce what has been called “information overload”. Many universities and public libraries use information retrieval system to provide access to books, journals, and other documents. Web search engines are the most visible information retrieval application.
An important component of information retrieval system is the form of information delivery implemented in the interface software package. Establishing a multipurpose information retrieval system interface for research, cataloguing of manuscript co...

The expression “unstructured data” usually refers to information that not reside is a traditional row-column database. As you might expect, it’s as opposed to structured data the data stored in fields in a database.
Unstructured data files often include text and multimedia content. Examples include the e-mail messages, word processing documents, videos, photos, audio files, presentations, web pages and many other kinds of business documents. Note that while these sorts of files may have an internal structure, they are still considered “unstructured” because the data they contain doesn’t fit updates in a database.
Experts estimate that 80 to 90 percent of the data in any organization is unstructured. And the amount of unstructured data in enterprises is growing significantly – often many times faster than structured databases are the rise.
There are two types of data. They are unstructured and multi-structured. Unstructured data comes from information that isn’t organized or easily interpreted by traditional databases or data models. This is usually in text format.
According to research, the people accountable for managing an organization’s database are called database administrators. The importance of a database administrator in a society should not be overlooked or treated with levity because they are fully in charge of data’s and information. Some of the examples of popular database management systems are My SQL, Oracle, etc. One of the major roles of a database administrator is to ensure database security. He or she is in charge of fixing security issues and complications that could
Most users will find what they are looking for the first times when conducting searches due to the database sufficiently being able to decode natural language. As users navigate through the website they will find many icons and tabs to help them through their searches. One does not have to be an expert to conduct searches using this database and will be able to use the simple search index to retrieve a desirable number of sources if the user knows exactly what they are trying to retrieve. This database would be an essential tool for students, teachers, or any patron to meet their informational
Data structure- In order to use unstructured data that does not fit neatly into rows and columns the non relational databases are designed to do this. As most of the data generated is unstructured this is a definite requirement. Scaling-by taking advantage of cheap ,commodity servers the system can be scaled horizontally.
Document Databases are similar to Key/Value Stores but documents, not values, are stored within the database. Documents can come in many different forms such as XML, Microsoft Word documents, and even PDFs. Like a Key/Value Store, a Document Database will assign a key to each document a unique key in order to locate it and the end users can query by the key. The...

Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
To indexing system, new documents are added and all users accessed them immediately if documents are indexed and created. End-users can do their jobs
"Although fully searchable text could, in theory, be retrieved without much metadata in the future, it is hard to imagine how a complex or multimedia digital object that goes into storage of any kind could ever survive, let alone be discovered and used, if it were not accompanied by good metadata" (Abby Smith). Discuss Smith's assertion in the context of the contemporary information environment
A database is a structured collection of data. Data refers to the characteristics of people, things, and events. Oracle stores each data item in its own field. For example, a person's first name, date of birth, and their postal code are each stored in separate fields. The name of a field usually reflects...
The flat file databases, hierarchical databases and network databases are usually referred as legacy databases. They represent the ways of people which is used to organize information in the prehistoric times, about 30 years ago.
Information Retrieval is simply a field concerned with organizing information. In other terms, IR is emphasizing the range of different materials that need to be searched. Others researcher said that IR is the contrast between the strong structure and typing a database system with the lack of structure in the objects typically searched in IR. The actual process in information retrieval systems is it has to deal with incomplete or under specified information in the form of the queries issued by users. IR uses the techniques of storing and recovering and often disseminating recorded data especially through the use of a computerized system.
Nowadays, information is the cornerstone of the modern enterprise and the web became the largest and most accessible information resources. The ability to gather, arrange, manipulate information with computers has given practice as well as for business people in order to manage information in an effective way. Information retrieval is a process and techniques of searching and interpreting information in order to store the data for easy retrieval when needed. The article entitled “Seven Ages of Information Retrieval”, the author who is Michael Lesk explained about the history or the beginning of information retrieval based on the theory of Vannevar Bush’s 1945, Warren Weaver in 1949 and also related to theory of Shakespeare 1955 which is seven ages of man, starting from infancy and leading to senility.
Example of the non-structured data is an email and the word processing documents. An email is the message that being distributed into the recipients using an electronic. It is being sent from one computer user to another user. Example of the word processing documents is the Microsoft excel. It is spreadsheets that being produce by the Microsoft for calculating, graphic tools, pivot tables and a macro programming language. This is because the files may have internal structure but it is considered as the non-structured data because the data in the database is still unstructured.
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.
