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.
The DBMS has a function that can be differentiate from the information retrieval system. The DBMS have the ability to store, update and retrieve the data. This is the main function of the DBMS because the database can be used if there is any record is being stored into the database. The record need to be retrieve first, then it can be change by the database administrator as it will be the record has been updated. The DBMS will protect the structure of the data structure.
Another function of the DBMS is the concurrency control services. Database Management System must ensure that the database is updated correctly because the database can be used by many multiple users. The DMS enable many user to access the data concurrently. The database managements system will help from ay data loss. It have the features which that can support the updates like batch processing, locking, two-phase locking and the time stamping.
The DBMS function is it has recovery services. It means that if the database is damaged, the database management system will recover the records and all the information. The data and the records need to recover and backup so that it will not be permanently lost. The regular backup is needed because the user doesn’t know what will happen to computer and the data may be loss.

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.

Information Management has to do with capturing information, efficient planning, organizing and evaluating the information to interpret for an organization to make well informed decisions. (Hinton, 2006) The main reason organizations depend on information is to improve its overall management in order to yield significant operational benefits in all areas of the organization and importantly its overall efficiency, competitiveness and responsiveness. The improvements either need expansion in the amount of information required or implementing a new information management system.(Power, 1983) The information management system is effective in organizations when the activities are shared amongst various groups, preparing them for change in the information system by identifying problems and evaluating it and gradually integrating actions in the project for successful implementation. (Bass, 1983), (Mintzberg, Rasinghami and Theoret 1976). Most organizations believe Information Technology and Information Management is the same but according to Hinton (2006), while Information Technology is an important role in an organization. Information Management is broader it helps the organization to build, maintain and re-build its business processes and information system.
A management information system (MIS) is an information collection and analysis system that facilitates access to program and participant information."(mays.tamu.edu, 2013) This system is usually computerized. Businesses use MIS at all levels of operation to collect, process and store data. Management uses this data in the form of information needed to carry out the daily operations of the business. Everyone who works in business, from someone who pays the bills to the person who makes employment decisions, uses MIS. In fact, many (if not most) companies concentrate on the alignment of MIS with business goals to achieve competitive advantage over other companies. "The major components of the MIS are the database, the model base, and the user interface. The database is used to store important data, the model base has the required statistical models in order to analyze the large amounts of data, and the user interface allows the user of the software to navigate through it and use it with ease."(mays.tamu.edu, 2013)
If updated information is lost or misplaced, then the employees will have to update information again which is time consuming as if they made backup in the first place they could have been focusing on something else in that time, they will fall behind in their work. Another way it effects John Lewis is because it prevents them from losing business such as its employees and customer information, which could difficult the way they work so for instant making regular backups ensures that John Lewis can always have access to the information they need without them constantly worry about losing it. This will protect John Lewis staff and its customers as they will not be lost. If John Lewis keep backing up their information this will save them a lot of time and money in case anything happens. One way to this is that John Lewis can automatically put the computer using a software than auto synchronization their important files in certain times so that they will not forget to do so as the system already did it. If they did this, then this will stop from losing work at all which would make them spend money if they had to redo it all again. This will take a lot of time than
Disaster recovery saves data so that your organization is able to recover from a disaster. Why’ll business continuity is a completely different process it allows your organization to continue business during a disaster. In layman terms you can still access your organizations data with little to no downtime.
Backup copies are processes that are used to save information. It is to say, a user wants to save all the information or part of the information available on the PC up to this moment; will make a backup copy in such a way that it will save the information in some technologically available storage, the urgent care clinic, the Systems area has two of the Servers as Backups administrator (Allen 2004)[2]; for later if a loss occurs in the computer equipment of one of the users and information is lost, from the Systems area the process of restoring the information to the date of the last backup made by the end user can be performed. In order for the process to be functional, users must periodically complete the process according to the indications given by the Systems
The first type of Big Data used in military logistics is the structured data, which is data that has been stored in the databases in an orderly manner. In military logistics, the two sources of structured data are machines and humans. Examples include GPS data, usage statistics of vehicles, ships and aircrafts, and data from medical devices. The second type of structured data is unstructured data, which is data that resides in the traditional column databases and have no clear format in storage. Examples include the mobile data, and data from satellite images about certain terrains (Sagiroglu & Sinanc, 2013).
Substantially, to fundamentally elucidate an information system, it is essentially a connected set of elements produced by people and managed through computers which allows the collection and distribution of data, to summarise the term it is generally a database. Data is a plural for datum which are elementary recognisable facts, information is datas that has been correlated so that context is formulated. To interpret data security, it is an assortment of facts which is translated to information secure on an encrypted server due to its personal state. In addition, the majority of security systems within modern technology are encrypted with pass-codes. However, database management systems (DBMS) can be breached in several ways including weak
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"
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.
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.
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.
A database management system is a collection of programs that allow users to create and maintain a database. Even though there are numerous advantages for using database management systems, there are a few disadvantages. Such disadvantages include complexity, size, performance, and the associated costs of a database management system. The advantages of a database management system outweigh the disadvantages, but one should understand the disadvantages to ensure they have a complete understanding of the system.
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.
You can think of database as godown or warehouse which is used to store different type of things. Technically,a database is a collection of information organized
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.
