Why is there a problem in traditional master data management?5 answersTraditional master data management (MDM) faces challenges due to the existence of siloed or outdated data sets in highly globalized and digitized supply chains. This leads to difficulties in integrating enterprise information and meeting stakeholder requirements for analysis and reporting. Additionally, the presence of duplicate data in various forms poses a challenge in data management processes, emphasizing the need for sound data governance. To address these issues, a centralized MDM system is crucial to maintain consistent and up-to-date data across all systems within an organization. However, issues such as manual identification of failures in data synchronization and reprocessing events have been identified, highlighting the necessity for innovative solutions like the introduction of AI and ML capabilities in MDM systems.
How to ensure safety of a database?4 answersTo ensure the safety of a database, organizations can follow a methodology that includes several steps. First, they need to identify and assess potential threats and evaluate existing security measures. Implementing multi-layered defense, enforcing the principle of least privilege, and regularly updating and patching the database management system (DBMS) are crucial. Regular security audits, user awareness training, and data encryption should also be implemented. Monitoring and logging database activities, developing an incident response plan, and staying updated with the latest research and best practices are important for continuous improvement of security measures. Additionally, using cryptography with a genetic algorithm can provide dual protection for the database, making it more secure. Transparent encryption and decryption operations using a data key from the system file level can ensure quickness and safety. Finally, setting access channels, permissions, and performing regular vulnerability detection and repair are essential for enhancing database security.
What are the challenges in developing database systems?5 answersDatabase systems face several challenges in their development. One challenge is ensuring the security of the databases, including protecting sensitive data and addressing vulnerabilities that could be exploited by unauthorized access. Another challenge is the implementation of distributed database systems, which can be hindered by unreliable network technology and high costs. Developing a valid dietary glucosinolate database also presents challenges, such as determining the appropriate sample preparation procedures and analytical methods for quantification. Additionally, the rapidly changing environment for database systems introduces new challenges, including adapting to advancements in hardware technology and handling new types of data resources that do not conform to the traditional relational data model. Finally, the evolving dynamics of database management systems, driven by factors such as increased data production and the need for real-time processing, create a new set of challenges for the future.
What is the difference between electronic data processing and manual data processing?4 answersElectronic data processing and manual data processing differ in terms of the methods used to handle and manipulate data. Electronic data processing involves the use of electronic devices, such as computers, to perform various data processing tasks. It includes processes like type conversion, exception handling, and modeling of data using machine algorithms. On the other hand, manual data processing relies on human intervention and manual labor to process and analyze data. It may involve tasks like selecting and processing multiple pieces of data simultaneously, based on user input and predefined data processing modes. The aim of electronic data processing is to simplify user operations, improve data processing efficiency, and enhance the overall user experience. In contrast, manual data processing may require more effort and time, leading to lower efficiency.
What are the common problems in manual enrollment and Billing system?5 answersManual enrollment and billing systems face common problems such as errors in enrollment information due to manual operation. These errors can be prevented by implementing a self-help enrollment system that allows students to log in and access enrollment information from a database, ensuring efficient and accurate enrollment registration. Billing systems also encounter issues such as billing errors caused by signal leakage. To address this problem, a billing system can be designed to generate and send passage notification data, which includes user ID and time of passage, to a central device for billing data storage. The central device can then search for and compare the received passage notification data with existing billing data to prevent errors and ensure accurate billing. By addressing these common problems, manual enrollment and billing systems can be improved to provide more efficient and accurate services.
What are the advantages of using a computerized database over a manual database?2 answersUsing a computerized database offers several advantages over a manual database. Firstly, it allows for the easy and efficient storage and retrieval of data, as demonstrated by Chauhan et al.. Additionally, a computerized database eliminates the need for manual indexing and filing, as mentioned by Wallach et al.. This saves time and simplifies the process of locating and organizing information. Furthermore, a computerized database can provide real-time access to data, as seen in the college management system developed by Chauhan et al.. This enables users to access and update information from anywhere within the institution. Lastly, a computerized database can improve the quality of research and learning, as reported by Deminco. Students using ERIC-on-CDROM found that it enhanced their research quality, learning, and motivation. Overall, a computerized database offers efficiency, accessibility, and improved outcomes compared to a manual database.
