Data Management Issues and Business Impact 1. Data Access Data Access can be defined as the way the users can perform a required action on the data stored in the database system such as adding new records into the database, apply changing to the current data stored in the database, delete any record from the database, or retrieve any record from the database system. Outline business impacts For any business operation, employees need to access the required data to provide service for the customers. In the banking organization, tellers or cashiers may need to perform insert operation into the database for the customers who want to do deposit and perform update operation for customers who want to withdraw money from their accounts. If data access tool or methods are not available or works well, bad impact will be upon the business which will interrupt the business’s main services and lead to revenue loss. However, if the data access is available and work well, a good impact will be on the business services and therefore lead to increase in revenue collection and profitability. Discuss the weakness and strengths of DBMS (eg, MS Server 2008 or ORACLE) The strenghts of DBMS particularly fall SQL Management Studio and SQL Editor where they allow the users to perform DDL operations and DML operations. The weakness is the users must have acquired the appropriate skills and knowledge to use the DDL and DML commands properly otherwise the powerful features of the DBMS will cause unfavourable (harmful) to the database system. 2. Data Shared Use Data Shared Use can be defined as the way data is shared amongst several numbers of users. Sometimes two or more users want to apply some changes to the same records stored in the database system while at the same time some users want to view or read those particular records.

In most business operations, data is shared within the department and across other departments, and even across all branch offices in different geographical locations. With the banking business as an example, sometimes the bank wishes to make direct deposit to its customers’ accounts for interest fees while at the same some customers make normal deposit at the same time. If shared use of data is not capable to functioning properly then the bank in the abovementioned case will unable to apply the interest charge properly and will lead to unhappy customers and therefore cause revenue loss. However, if the data shared use feature is working well then the bank can be able to apply any charges to its customers’ accounts independently from the deposit or withdraw made by the customers. Therefore, a favourable impact occurs to the business operation and leads to increase in revenue collections.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
