INF30010 / 80037 Database Administration Assignment 1 Contemporary Issues in DBA August 2017 INF30010 Assignment 1 1. Introduction Database Administration is fundamental to modern day business: without good database administration, database designs can become outdated, performance may become suboptimal, user needs are less likely to be met over time, data loses integrity, and the whole system may completely fail. All mainstream DBMS require ongoing maintenance. It is the role of the Database Administrator to keep database systems online, up-to-date, and functioning efficiently, and delivering on user demands. They can play a role in evaluating new systems or updates, designing the database, establishing use and access policies, tuning the database, ensuring backup and recovery, and planning for future developments. Database Administrators and tools for administering databases have been around as long as databases: new tools emerge over time, as do specialist roles – these developments depend on both the technological opportunities and business needs of the day. In this assignment, working in teams, we challenge you to explore some of the contemporary challenges and opportunities facing organizations and database administrators. To this end, each group will focus on a specific DBA issue, independently and critically analyse relevant literature and tools, and communicate findings via a group report and presentation. The aim is for students to better understand database administration in the context of modern organizations, in terms of performance requirements, monitoring approaches, available tools, and improvement strategies, INF30010 Assignment 1 2. Activities and Requirements To successfully complete this task, you and your group will need to complete the following tasks and requirements. If you’re unsure about any of the steps please consult your lab instructor or the course convenor. i.  In Week 3 of the unit, your lab instructor will help organize you into groups of 4 students ii.  Each group will either select or be allocated a topic (see below). Each topics consists of brief background and set of questions that needs to be understood and researched. iii.  In addition to the above, each group should ensure they’ve answered the following general questions, relevant to all topics: 1) Critically examine the societal and/or organizational trends driving the uptake of the DBA-related technology; 2) Explore and explain the technical nature of the DBA-related technology (i.e. hardware, software, networks, models, standards/protocols) and how these complement or compete with conventional DBA tools; 3) Explain the approaches and potential challenges for implementing the DBA technology within organizations; 4) Identify and articulate any changes to the role of DBA – or new roles a DBA might be required to undertake; 5) Hypothesize what the impact of your topic area will be on DBAs (individuals and the industry), organizations, and society more broadly – in the next 5 to 10 years (you might develop multiple scenarios); 6) If possible, identify a real case study organization or individual and use it help further demonstrate and justify your answers to the first five questions (note: you can use DBA industry contacts here, or make use of grey literature, or even academic literature from the library) iv.  Before commencing the research, the team must decide and record how it plans to work together. The following should be completed: a) decision on whether to appoint a team leader; b) outline of when, where, and how often the team plans to meet; c) a code of set of rules to which all team members must adhere to, including incentives or penalties in cases where team members fail to adhere to the code; d) articulation of the tasks than need to be completed by the team; e) clear allocation of which team members will complete what tasks; f) justification that the allocation of tasks is equitable; g) a timeline or Gantt chart identifying when each task is to be completed. This team plan should be recorded by the group and submitted as an appendix to the final report. Minutes of each meeting should also be kept and submitted in the appendix. v.  Using iii as your guide, investigate and research your allocated topic area. You can make use of academic literature, grey literature, web resources, and case studies. You can also speak with industry experts and/or leaders within the field. If you do this, be sure to seek their permission to be recorded (verbally or written) and make clear that the information they provide you will only be used within your group report. Your topic might also require you to analyse, test, and apply different database administration tools – either online or available from within Swinburne’s ICT suite of hardware and software. When undertaking these investigations remember you’ll need an approach for assessing the tools and record your findings. vi.  Synthesize your research findings into a structured report. The report should be no longer than 3000 words. It should be written in English and make use of correct spelling and INF30010 Assignment 1 grammar. Include a title page, executive summary and contents page. You may structure the sections however your group prefers, but, it should be logical and well organized. If necessary, you may include SQL statements and/or scripts as needed. These should be added as an appendix. The report should, where necessary, cite the relevant literature used to make arguments and arrive at conclusions. A reference section (or bibliography) should be provided at the back of the report: be sure to use a standard and consistent approach to referencing. Likewise, if you used interviews with industry contacts, you should disclose and provide citations in the appropriate places within the report. The backend of the report should include sections covering discussion, recommendations (if any), and conclusions. Each group member should make a contribution to the report. The report should be submitted in hardcopy at the end of Week 8. The group report is marked out of 20 (or 20% of the final unit grade). vii.  Your group should also convert the report into presentation format. Your group will present your topic during Week 7 or 8 of the course. Your group can choose the format of the presentation, however, it should run for 20 minutes and allow for 10 minutes of questions. You can make use of MS Powerpoint or other presentation software and tools. Ambitious groups might like to include (and even create) videos, animations and other form of multimedia. Each group member should be available to answers questions during question time, although, not all group members necessarily need to present during the presentation. The group presentation is marked out of 10 (or 10% of the final unit grade). Combined the presentation and report are marked out of 30 (or 30% of the final unit grade). INF30010 Assignment 1 3. Topics Below is the list of topics. You and your group will be assigned one of these topics. For each of the topics, your report and presentation should cover the general questions (see Section 2, part iii) and any specific questions raised in the topic descriptions below. a) DBAs in the Cloud Over the last 5-10years, cloud service offerings have grown exponentially in uptake. Organizations have been quick (and sometimes slow) to incorporate cloud services to store data and manage data. What is driving this uptake? Can you provide examples and/or compare common cloud data storage and management service providers? What technologies do they make use of? How should DBAs evaluate cloud services? What challenges does storing data off premises in the cloud create for DBAs? Does the DBA remain ultimately responsible when data and database services are put into the cloud? What advice can we give to DBAs when managing data in the cloud? b) Big Data, NoSQL – the end of DBA? Big data is a hype. Big data is a reality. Whilst structured data dominated the world of databases for decades, since the 2000s, solutions for creating and storing unstructured data (think NoSQL) have gained in prominence. What is big data? What is driving big data? How is big data different to conventional data? What has driven the rise of unstructured data management solutions? What are some of the key contemporary tools available for managing unstructured data? Compare different offerings. What is driving the trend to integrate SQL and NoSQL solutions? Can you provide examples? How do they work? What is the role of databases and database administrators in the age of big data? Does NoSQL mean no DBA? Is there any difference for a DBA working in a NoSQL environment? c) Open Source DBMS vs. Commercial DBMS Open Source DBMS have rapidly gained in popularity over the last decade. What is the difference between an Open Source and Commercial DBMS? What are some of the most popular Open Source DBMS? Are they technically different to some of the more common Commercial DBMS? If yes, in what ways (perhaps provide some comparisons)? Is database administration any different with an Open Source Solution? If yes, explain. Why have Open Source gained in popularity? Provide some examples of organizations that have commenced using Open Source DBMS (perhaps alongside a Commercial DBMS). What does the rise of Open Source mean for DBAs? d) Database Diversity 4 DBAs DBAs are increasingly being asked to be responsible for multiple databases running on multiple platforms. In modern contexts, a DBA might be responsible for administering dozens of databases at any one time. What is driving this proliferation in diversity? Is this trend likely to continue? Is there a limit? What are some of the most common vendor technologies that a DBA needs to be across? What are the key differences between them – and what challenges does that create for the DBA? What are some of the good practices DBAs can put in place to help manage this increasingly complex and demanding environment. e) Database Performance, DBAs, and the Age of the App We’re living in the age of the app. Databases lie at the heart of most apps. The challenge for DBAs is that database performance is now, more than ever, more closely linked to application performance – and vice versa. What has driven business to focus more applications? Is this trend likely to INF30010 Assignment 1 continue into the future? In these contexts, what should database performance be measured on? What can DBAs do at the organizational level to respond to the focus on applications (hint: think about DevOps)? What are some of the technical tools and options available to DBAs to improve performance - of both app and database? f) Automation of DBAs Automation of administrative and maintenance tasks is a hot topic across many industry sectors – database administration included. Is automation impacting on database administration? What might be driving the trend? What are some of the example technologies and tools that can be used to automate DBA tasks? How do they work? What do they enable? Does automation eliminate the need for DBAs? How might automation change the roles and tasks of DBAs? What tasks can be automated? Which tasks cannot? How is automation going to impact on the field of DBA in the next 5 to 10 years. g) DBA Offshoring In developed economies, IT offshoring has been an increasing trend over the last decade – particularly in highly repetitive tasks, perhaps including DBA? What is offshoring? What do you think, are the tasks associated with DBAs the kind that can be offshored? Which tasks can? Which cannot? What might be some example technical set ups in terms of backup and recovery, when it comes to offshoring DBA activities? What are some of the benefits of DBA offshoring? What are some of the risks and problems? Can you identify success stories or case examples? What about failures? What can a DBA expert do to respond to offshoring? h) DBAs 4 Data Warehousing and BI As early as the 1970s, Data Warehouses emerged in response to the opportunity to leverage of transactional data held in operations databases. What is a data warehouse? What are some of the common performance issues that Data Warehouse DBAs must deal with? What technical tools and approaches are available to DBA Data Warehouse specialists? How do they work? What future trends are evident in the domain of Data Warehousing? How will this impact on the DBA? Does the DBA need to upskill? Will the Data Warehousing DBAs role change or further specialize within an organization? i)  Database Security and DBAs Security has always been a key focus of the DBA toolkit, but, its importance has been emphasized in recent times. What is driving the increased focus on database security? What are some of the most common attacks? Can you identify case examples and identify at what level a security breach occurred – did it relate to weaknesses in the database administration? What is the role of the DBA when it comes to data security? What tools does a DBA have to help maintain data and database security? Are there newly emerging data security tools? How do these differ from conventional tools? How can a DBA contribute to IT security more generally across an organization? How should DBAs work with IT security teams? INF30010 Assignment 1 4.
