Recommended: Purpose of a database management system
People came up with the term database as the computer industry was growing in popularity. A database management system means exactly what its name is, it is computer software designed to create and manage databases. This software gives users and programmers an organized way to retrieve, create, update, and manage data. A database management system (DBMS) creates ways for end users to read data in a database as well (MindTap). The DBMS basically serves as a crossing point between databases and normal users or programs, confirming that data will constantly be organized and stay accessible pretty easily. The three important things that the DBMS manages are the data, the database, and the database engine. All of these elements help deliver …show more content…
They may be able to stop or block changes to information based on the environment of the business and individual in charge of the data. In order for employees to be allowed to view, change or recreate certain parts of database systems, they must carry proper skills that are needed by the company or program that they work for. The owners or administrators usually have complete control on which person is able to see certain types of information on the database management systems. Database management systems are extremely important to organizations and businesses because they offer a very efficient technique to using many types of data within that business or organization. A lot of data within the business field that can easily be managed is employee records, pay rates, student information, accounting, currency, and inventory on products (MindTap). These database management systems are built for versatility, and this allows users to have easier and more precise access of data. Database management systems save massive amounts of time because without them, tasks would have to manually be …show more content…
This allows each user or worker to access that data from a different location, so when a company has to update an employee’s record, the updated data changes in the original location. A few more benefits that companies have while using database management systems are the enhanced data reliability, upgraded flexibility of information systems, increased accessibility and obtainability of data and information and logical and physical data freedom (MindTap). Database management systems allow users to store their data more efficient than other ways because the data is only in one location. A pretty decent database management system that companies may use is Microsoft Access. This database gives workers the ability to manipulate other data in a database. Microsoft Access is one of the tiniest database development tools available for users and businesses. Businesses that are bigger and manage more quantities of data at a time, normally invest their money into more industrial database systems. These systems include IBM DB2, Microsoft SQL Server, and Oracle, and all of these database systems are much more commanding and pricey
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)
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.
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
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.
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"
• Improve the access to information and collaborate information sharing between different entities within the administration. Since an ERP system would be using a single data store across all departments, there will be less time and effort spent on requesting, authorizing and delivering information across different departments. Access control can be imposed by the ERP system itself.
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.
Normalization, Integrity and Security are the important role for a DBA, Normalization helps to avoid data redundancy by reviewing data base structure at certain level. It helps to build an effective data model. Data Integrity provide some level of assurance over the information getting store and retrieved from database, DBA has to understand all DBMS features use them correctly for Data Integrity. Data Security is toughest part for DBA, auditing and multiple level security can protect data but none of them provide complete security, security can also be managed by encrypting and masking the organization data.
In order to resolve network related problems The Airframe Corporation (TAC) has decided to upgrade the existing network consisting of a mix of Token Ring and shred Ethernet hubs to a switched Ethernet network. The purpose of this paper is to discuss several aspects of the project plan for the upgrade. This discussion will be made in threes sections. Section one will include project definition, while section two will deal with work breakdown structure and estimated schedules, and section three will cover costing and risk analysis.
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 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.
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.
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 Accounting Information System (AIS) can be defined as software that helps accountants to collect data and process it to create information ((Bagranoff, Simkin and Norman 2010)
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.
