Database Administration and Concurrency Management Essay

Concurrency control methods used in database management systems, primary decisions in the database administration, reference list.

When it comes to defining the best concurrency control methods, one must give credit to the optimistic (validation) one since it prevents a company from facing a deadlock (Topi &Tucker, 2014). The approach in question allows for blocking a transaction from occurring once it fails to pass a certain stage. Dismissing the given strategy, a company may fail to track down the factors that cause transactions to fail and, therefore, overlook some of the major obstacles. Particularly, the distributed locking technique (Topi &Tucker, 2014) should be used as it helps introduce different locks at the existing sites and, thus, make data sharing more flexible. The refusal from DLT and the adoption of the uniform approach make the process of database management less convoluted yet jeopardizes the security of the entire data system.

For instance, the specified method can be used in case a company has several affiliates and, therefore, several databases with the corresponding data. Once the decentralized strategy is used, the members of each department will be able to navigate the data related to their area. Consequently, less confusion will occur.

To manage the data that grows consistently, a database manager must use the strategy that will help arrange the incoming information and process it fast. Particularly, the information processing tools, including the ones for arranging data based on its value, the identification of its mean, median, and mode, the basic statistical analysis (e.g., standard deviation identification), etc. must be conducted.

To facilitate data integrity, one should consider the tools such as PeopleSoft ( Data integrity tools , 2015) and the related software. In addition, one must consider making security tighter by introducing a system of passwords and ID tools. Last but definitely not least, the basic security principles such as non-disclosure of corporate data to the third parties must be reinforced in the organization.

Database administrator (Dba)

• Software installation and Maintenance: A DBA administrator often collaborates on the initial installation and configuration of a new database. The system administrator sets up hardware and deploys the operating system for the database server, and then the DBA installs the database software and configures it for use. As updates and patches are required, the DBA handles this on-going maintenance. And if a new server is needed, the DBA handles the transfer of data from the existing system to the new platform.
• Data Extraction, Transformation, and Loading (ETL): Data extraction, transformation, and loading refer to efficiently importing large volumes of data that have been extracted from multiple systems into a data warehouse environment. This external data is cleaned up and transformed to fit the desired format so that it can be imported into a central repository.
• Specialized Data Handling: Today’s databases can be massive and may contain unstructured data types such as images, documents, or sound and video files. Managing a very large database (VLDB) may require higher-level skills and additional monitoring and tuning to maintain efficiency.
• Backup and Recovery: DBAs create backup and recovery plans and procedures based on industry best practices, then make sure that the necessary steps are followed. Backups cost time and money, so the DBA may have to persuade management to take necessary precautions to preserve data. System admins or other personnel may actually create the backups, but it is the DBA’s responsibility to make sure that everything is done on schedule. In the case of a server failure or other form of data loss, the DBA will use existing backups to restore lost information to the system. Different types of failures may require different recovery strategies, and the DBA must be prepared for any eventuality.
• Security: A DBA needs to know potential weaknesses of the database software and the company’s overall system and work to minimize risks. No system is one hundred per cent immune to attacks, but implementing best practices can minimize risks. In the case of a security breach or irregularity, the DBA can consult audit logs to see who has done what to the data. Audit trails are also important when working with regulated data.
• Authentication: Setting up employee access is an important aspect of database security. DBAs control who has access and what type of access they are allowed. For instance, a user may have permission to see only certain pieces of information, or they may be denied the ability to make changes to the system.
• Capacity Planning: The DBA needs to know how large the database currently is and how fast it is growing in order to make predictions about future needs. Storage refers to how much room the database takes up in server and backup space. Capacity refers to usage level. If the company is growing quickly and adding many new users, the DBA will have to create the capacity to handle the extra workload.
• Performance Monitoring: Monitoring for performance issues is part of the on-going system maintenance a DBA performs. If some part of the system is slowing down processing, the DBA may need to make configuration changes to the software or add additional hardware capacity. Many types of monitoring tools are available, and part of the DBA’s job is to understand what they need to track to improve the system.
• System Tuning: Performance monitoring shows where the database should be tweaked to operate as efficiently With effective monitoring, it is possible to proactively tune a system based on application and usage instead of waiting until a problem develops.
• Troubleshooting: DBAs are on call for troubleshooting in case of any problems. Whether they need to quickly restore lost data or correct an issue to minimize damage, a DBA needs to quickly understand and respond to problems when they occur.

Database Administrator

The profession

A person who administers the computer database of an organization is known as a database administrator or DBA. A database has a structure and design and it should confirm to database design concepts in order to be called a database. The role of a database administrator is to devise strategies for a database development, monitor and improve the performance and utility of the database, besides planning for the expansion of the database based on the future needs of the organization. In this assignment, we look at the skills required for a database administrator, duties and responsibilities, work conditions as well as the remuneration for a database administrator.

Requirements

Installation, Configuration, upgrade and migration

Let’s find out together!

Database installation is the responsibility of the Database Administrator (DBA), the DBA should have knowledge of the hardware and software requirements for running the database server efficiently. The DBA should later communicate these requirements clearly to the system administrator and install the database and various options in the database product for deploying the database. The DBA should install the latest releases and patches and keep the database up-to-date, robust and efficient. The DBA should migrate the database from the old database server to the new one in case if a new server is installed for the purpose of increasing speed and efficiency of the database.

Backup and recovery

The DBA should implement and test a backup and recovery plan for the database just in case if there is a database crash. The DBA should ensure proper and scheduled backups of all databases and files so as to ensure recovery of these files in case if there is a database crash. In the event of a database crash, the DBA should ensure quick use of backup files to bring the database back to operational status without loss of data. Databases may fail due to several reasons, and it is up to the DBA to develop a strategy to recover databases in the event of database failure. Creating backups involves costs for the organization and the DBA should inform the management of these costs/risks.

Database security

Each database product like Oracle or Microsoft SQL Server has a particular security model and the DBA should be well aware of these models in order to control access to data. The three important tasks are authentication, authorization and auditing. Authentication is the setting up of user accounts like providing user identification and password to users, authorization is granting permissions on various parts of the database and auditing means that the database confirms to regulatory laws such as Sarbanes-Oxley and HIPPA as far as reporting requirements are concerned.

Storage and planning

The main purpose of any database is storage and retrieval of data. The DBA must plan the storage requirements and monitor disk space availability. The DBA should keep a tab on growth trends so that the DBA can advise the management on long-term plans.

Performance monitoring and tuning

The DBA should monitor the database for any issues such as slowing down of database processes and correct these issues when they occur. Hardware capacity, operating system configuration and database configuration all can contribute to the slowing down of the processes running on the server. Database layout and disk drives, database indexing methods used, and the query methods used can contribute to the processes running slowly on the database server. The DBA should use the best monitoring tools to monitor all these activities and tune these activities just in case if a database slows down.

Troubleshooting

When there are issues with the database, the DBA should quickly identify and rectify the problem without losing data or without aggravating the situation. For these reasons, the DBA should possess strong knowledge of troubleshooting methods and tools to ensure smooth and efficient handling of the database.  

Work conditions for a DBA

DBAs work in an office or a lab, and they work for 40 hours a week mostly, but, sometimes, they may work in the evenings or during the weekends so as to meet deadlines. Like all other office workers who spend more time on computers, DBAs can suffer from eye strain, back pain, hand and wrist pain etc.

Remuneration for a DBA

According to the U.S. Labor department statistic held in 2010, average yearly wages of database administrators were $73,490 in 2010; the highest payments were around $115, 660, while the lowest - around $41, 570 a year (Bureau of Labor Statistics, 2010).

Opportunities for a career advancement

DBAs can grow to become senior DBAs, DBA consultants, managers, director of database administration/information technology department etc., provided that these opportunities exist in the organization that they work for. Otherwise, they can always move out to organizations that offer such career growth prospects (Bureau of Labor Statistics, 2010).

Related occupations

Some of the job occupations related to DBA are computer and information systems manager, computer hardware engineers, computer programmers, software engineers, and statisticians.

Future outlook

Job growth will not be rapid in this sector during this decade. The information technology sector will become more organized and process-oriented, and the job of the DBA is likely to be outsourced overseas (“Database Administrator”, 2010).

1. Do EMR and CPOE systems seem to have the potential to help Mountain View achieve its goals of achieving high-quality care and containment? Support you answers with examples of how you think these goals may not or may not be achieved. The EMR and CPOE have mechanisms that can help the MVCH achieve its goals and objectives as they make the process of administering services to different patients easier. They facilitate the service delivery process and ensure that there is proper data storage which can be easily accessed when needed. The EMR and CPOE also reduces the time for delivering services thus making service delivery more effcient as described by Dr. “Z” 2. In light of HIPAA and other regulations, securing and protecting other patient records is a primary requirement for MVCH. a) What data security issues would you expect mountain view to encounter if an EMR system is implemented which is accessible by physicians in the community, by laboratories and by healthcare organisations.

Confidentiality – if data is accessible to anyone in the insitution, then the confidentiality of the patients’ data will be compromised.

Data Integrity – data which is accessible to anyone is likleky to be manipulated at different stages in the organisation. b) What data security techniques described in this chapter could be used to address the issues. In order to eliminate the above problems, the hospital should consider using encryption for the data and also use of digital signatures which can help in making data more authentic. The encryption will help the hospital employees to access some data only if they have the decryption key thus making them authorised data handlers. The hospital should also introduce the use of access control so that only legitimate employees can access a given set of data in the hospital. 3. If MVCH decides to implement a CPOE system, how could access problems such as the one that Dr. “Z” experienced at another hospital be prevented? Since the implementation of theCPOE system results into access problems, there is a number of ways in which such problems can be eliminated. The physians should be granted access priviledges depending on the level that they occupy in the institutions. Data should not be accessible to anyone in the insitution. There should be a mechanism that haandles access rights of different categories of employees within the hospital. 4. Given that the Mountain View database you developed in SQL server already includes tables for physicians, orders and so on, do you think a full-fledged CPOE system could or should be developed internally? Why or why not? A fully fledged CPOE system should be developed internally so as to help the physicians to propely manage the data presented to them by the patients. The COPE system that is developed internally will be easily customised so as to enable the computerisation of all the processes in the provision of healthcare services at the insitution. 5. Dr. “Z”indicated that physicians might resist the implementation of a CPOE system. do you think that that would also be true for an EMR system? Why or why not? What would be critical success factors for implementing an electronic medical record at MVCH? Dr. “Z” indicated that physicians might resits the CPOE implementation since it was hard to implement due to the multiple steps involved, and difficult of access. He also noted that this system was still prone to errors. However, the implementation of the Electronic Medical Record system is likely to be receive positively by most of the physicians in the hospital. This is due to the following reasons: i. They help in saving on the cost and space for keeping the medical records ii. It enables all the participants in the healthcare system to cordinate care iii. They also help in saving time iv. Doctors are known to have some undesirable handwriting. The use of the EMR will remove the possibility of the occurrence of such problems as computer font will be used. v. It results into enhanced quality of care vi. It also results into faster and more diagnosis treatments of different cases presented to them 6. Should Mountain View Community Hospital adopt a continuos data Protection (CPD) system? why or why not? What other back-up strategies might the hospital pursue?

Mountain View Community Hospital should adopt continuous data protection because of the following reasons:

The continuous data protection is easier and more efficient to use since the data administrator does not have to specify the point where he or she wishes to recover the data until he/she is ready to perform a restore. It therefore helps in eliminating the need for having scheduled backups. The CDP also helps in protecting against some effects of data protection as it allows the user to restore to a previous uncorrupted point. All the transactions that might have taken place during the corruption time are then lost. The CPD also requires less disk space than the traditional methods used to offer the backup services.

Other backup strategies that the hospital can pursue in order to ensure that their data is properly backed up include:

i. Backing up offline files and folders ii. Backing up browser preferences iii. Backing up of emails iv. Using sync tools to backup the data. 7. Do you think data storage at Mountain View Community Should be treated as strategic issue? Why or why not? Data storage is a strategic issue and should be handled with utmost care. Poorly stored data usually results into passage of wrong information. The patients’ data should be properly stored so that they can be used for future reference and patients will not be required to through the rigorous process of acquiring information. Patients’ data should also be stored with a lot of confidentiality. The data should not be accessible to anybody in the organisation. If patients’ information is leaked to the public, then there will loss of trust between the patients and the hospital administration. For the good of both the patients and the hospital administration, data should be properly planned and managed. 8. Do you think that data quality at Mountain view Community Hospital is a strategic issue? Why or why not? Data quality is also a strategic issue and should be taken into consideration by Mountain View Community Hospital. Poor data quality is usually a nuisance and results into loss of customer loyalty. The quality of data stored by the hospital can also compromise the services offered by the hospital. Data quality is therefore a strategic issue as it will help the hospital to properly manage data and also help the management of the hospital and the physicians to correctly administer their services thus improving the quality of services hence improving customer loyalty. 9. Which data and database administration issues described in chapetr 12 should be addressed by Mountain View Hospital’s special study as part of the long-range business and information systems plan? Why? The MVCH should address data confidentiality, Access and integrity issues. If such data administartion issues are properly addressed, then the patients in the hospital are likely to have more trust in the hospital. Data properly stored also help to control data access by competitors thus helping the hospital to improve their mode of service delivery.

Additional Question

How can views be used as part of data security? Views usually provide extra security as they help to limit the degree of exposure of tables used in the database to the outer world. They help in protecting access to and from the tables which are used in tha database. Once the degree of exposure has been limited, it is therefore easier to control and protect the data in those tables.

What are the limitations of views for data security?

The views are very slow. Their speed of operation is similar to that of query thus compromising on the data security. Views can also be eaily queried and data contained in the views be easily changed. This also jeopardises the security level of the data it represents.
