ISYS2120: Data and Information Management

Semester 2, 2021 [Normal day] - Camperdown/Darlington, Sydney

The ubiquitous use of information technology leaves us facing a tsunami of data produced by users, IT systems and mobile devices. The proper management of data is hence essential for all applications and for effective decision making within organizations. This unit of study will introduce the basic concepts of database designs at the conceptual, logical and physical levels. We will place particular emphasis on introducing integrity constraints and the concept of data normalization which prevents data from being corrupted or duplicated in different parts of the database. This in turn helps in the data remaining consistent during its lifetime. Once a database design is in place, the emphasis shifts towards querying the data in order to extract useful information. The unit will introduce the SQL database query languages, which is industry standard. Other topics covered will include the important concept of transaction management, application development with a backend database, and an overview of data warehousing and OLAP.

Assessment criteria

Minimum Pass Requirement

It is a policy of the School of Computer Science that in order to pass this unit, a student must achieve at least 40% in the written examination. For subjects without a final exam, the 40% minimum requirement applies to the corresponding major assessment component specified by the lecturer. A student must also achieve an overall final mark of 50 or more. Any student not meeting these requirements may be given a maximum final mark of no more than 45 regardless of their average.


The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

When you don’t meet the learning outcomes of the unit to a satisfactory standard.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

For every calendar day up to and including ten calendar days after the due date, a penalty of 5% of the maximum awardable marks will be applied to late work.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

  • Study commitment: A variety of learning situations will be employed during the unit of study, including lectures, on-line demos, tutorials, directed computer laboratory exercises, self-learning SQL exercises (`SQL Challenge`), assessed assignments, and a small practical database project. To benefit fully from this unit it is necessary to participate fully in all aspects of the unit of study.
  • Laboratories/tutorials: Laboratory and Tutorial work includes hands-on use of DBMS, an SQL online tutorial, and also practice in problem-solving related to the content.
  • Independent Study: Work on assignments and homeworks, reading material from notes/references, etc; this should allow students to engage with the material and to integrate it into their understanding. 5 hours independent study is expected each week.
  • Project Work (own time): Group Work on a practical database application project assignment (extra to time provided in Lab sessions). 3 hours of project work is expected each week.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. work effectively in a team with members whose skills and interests differ
  • LO2. understand the SQL mechanisms for basic concepts of data security and privacy
  • LO3. design a schema which says how information about a particular domain will be stored in a relational DBMS (given a conceptual data model), also be able to apply normalisation theory to evaluate or improve a relational schema, and be able to capture business rules as integrity constraints in a database schema
  • LO4. understand the concept of a DBMS, differences from other ways to store and share data, DBMS role in organisations, and the types of work done with a DBMS
  • LO5. work with data stored in a relational database management system, and understand table definitions including integrity constraints, extract information through SQL queries, modify information through SQL queries, and use views and permissions for security
  • LO6. understand how application software can use data stored in a DBMS, and understand the basic architectural alternatives for data management applications
  • LO7. understand the basic concepts of transaction management
  • LO8. understand the relational data model
  • LO9. connect general database concepts to both theoretical abstract formulations, and details of specific software platforms.
