Question
| Business Information Systems Any business information system will have two critical components: a computer network and a database system resided on the computer network. Many business related data (such as customer records, business financial data, company’s documents, employees’ records, etc.) are stored in the databases so that they can be shared among different users. Users can query databases to get the data and information they need. In 200 to 300 words, discuss the following: 1.Why database system is a critical component of business information systems? (Tip: Please provide at least one reason.) 2.Why IT department of a company needs to backup databases regularly? (Tip: Please provide at least one reason.) |
Answer
A database system is an integral component of any business information system primarily because it increases efficiency in information storage and sharing and reduces the overall costs of data management substantially. Essentially, these two benefits are intertwined. For instance, the database system optimizes organizational performance by providing a centralized platform for data storage in addition to facilitating the storage of large volumes of data for longer periods of time (Hoffer, 2011). Moreover, it allows for remote data entry since the servers can be accessed from any place by authorized personnel who are prompted to enter their password, thus enhancing security (Hoffer, 2011). It is an indisputable fact that without this system, the majority of tasks would have to be done manually including data handling and management. This approach would lead to a decrease in the productivity of an organization by increasing the running costs, for example, the hiring of more staff to enter data and manipulate it manually (Hoffer, 2011).
There are several reasons as to why an IT department ought to regularly backup the database system. Backing up entails making several copies of data either externally or using online servers such as cloud storage (Oszu et al., 2011). To begin with, it safeguards data from theft, damage and any other disasters that may occur. Both small and well-established organizations are highly susceptible to data breaches. As such, it is vital for business owners to invest in a secure database backup infrastructure.This enhances data security and guarantees handy access to valuable information without any restrictions whatsoever, including those relating to time and location (Özsu et al, 2011). Furthermore, technological developments have led to the emergence of cloud-basedbackup systems that are highly versatile in the sense that they abate costs by alleviating high spending on the installation of secondary storage media such as external hard drives.
