Differentiate between database management system and information retrieval system by focusing on their functionalities.
In short Database Management System is knows as DBMS. DBMS is a system that is uses a standard method of cataloguing, retrieving and running queries data. The DBMS operate to manage incoming data, then organizes it, and provides ways for the data to be modified or extracted by users or other programs.
Information Retrieval System or IR is finding material (usually documents) of an unstructured nature (usually text) that satisfy an information need from within large collection.
There are a few different between database management system and information retrieval system based on their functionalities. First, from the advance data modelling facilities. In DBMS there are provide the Data Definition Language (DDL) and Data Manipulation Language (DML). DDL is statement provides to define the database structure or schema. It is also to define data structures within a database. DDL is usually considered as a subset of Structured Query Language (SQL), also can be refer ...
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.
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.
Big Data is a term used to refer to extremely large and complex data sets that have grown beyond the ability to manage and analyse them with traditional data processing tools. However, Big Data contains a lot of valuable information which if extracted successfully, it will help a lot for business, scientific research, to predict the upcoming epidemic and even determining traffic conditions in real time. Therefore, these data must be collected, organized, storage, search, sharing in a different way than usual. In this article, invite you and learn about Big Data, methods people use to exploit it and how it helps our life.
and they do not know how to use a computer very well so they probably
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.
Big data is a concept that has been misunderstood therefore I will be writing this paper with the intentions of thoroughly discussing this technological concept and all its dimensions with regard to what constitutes big data and how the term came about. The rapid innovations in Information Technology have brought about the realisation of big data. The concept of big data is complex and has different connotations but I intend to clarify its functions. Big data refers to the concept of a collection of large and complex amounts of data that are found extremely difficult to notate or even process by most on-hand devices and database technologies.
Perhaps, before diving into concepts related to the history of DBMS, it would be prudent to present a thorough definition of DBMSs and their functions. A DBMS refers to a collection of software programs that aid in the construct...

Deductive database systems are database management systems which are basically designed around a logical model of data. In this type of database systems deductions are made based on the rules and facts stored in the database. We use a language called Datalog which are typically used to specify facts,rules and queries in database. Deductive Database is an advanced form of relational database. When we compare deductive database with relational database we can find that deductive database is more expressive than relational database but, when it is compared to logic programming system it is less expressive. These type of databases use many of the concepts which are specified in logic programming; rules and facts specified in the deductive database language. Deductive database have the additional feature of storing rules that enable inferences based on the stored data to be made. The explicit information is stored in the same manner as that of a relational database. So, deductive are mainly useful and more capable of storing large amounts of information and also perform reasoning based on the acquired information. Deductive has an additional i.e. it is declarative too. Instead of showing how to perform the operation it allows the user to query or update by saying what he or she wants.
A database is a collection of data which is organized and easy for users to find data. Database can record massive amount of data, it can be use for business and organization’s purpose. Every organization should have database security to secure the information of the organization.
The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources.
Information seeking is a fundamental human activity in the pattern of collecting information and satisfying the users’ information needs. Information seeking behavior (ISB) can be defined how a user proceeds in gathering information from the recognizing a lack of knowledge to fulfillment of understanding.
Many administrators, executives, faculty, instructors, IT specialists, librarians, researchers, scholars, school teachers, students, and etc are searching and using information every day. Information is not easy to understand precisely. Internet and the World Wide Web (WWW), information is now delivered and disseminated across many applications, databases, networks, platforms, and systems in the networked information world. Information has a broad domain. Information is everything perceivable around us and only perceivable through our senses. Information exists in many different forms, such as codes, colors, events, facts, graphs, images, letters, lights, news, numbers, pictures, signs, signals, sounds, statistics, tables, texts, waves, and so on. Information can be collected, modified, organized, processed, stored, twisted, and transmitted for some specific purposes. While searching information, we need to define our information needs first before we try to access and locate information resources. Information can be broadly defined as any pattern that can be recognized by some system for examples a living organism, an electronic system or a mechanical device and or that can influence the formation or transformation of other patterns. In context of this assignment, information refers to knowledge communicated or received concerning a particular fact or circumstances. Therefore, by definition, information explosion can be viewed as a sudden increase of knowledge communicated or received concerning a particular fact or circumstances. It is information explosion that leads to information overload. According to Dictionary.com, Information Overload is an overwhelming feeling upon the receipt or collection of an indigestible or incom...
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.
increase in the variety of information needs, nature of publications and structure of library has created the
