Description

The course covers the basic principles of database systems as seen by users, application programmers and database administrators. A laboratory assignment develops these topics as a running example throughout the course. These include programming in SQL, as seen by a user querying or modifying an existing database, by a database designer, and by an application programmer invoking SQL from a host language. Course contents include:

The course is thus a typical first course in database systems, and occupies a traditional place in the curriculum.

Teachers

The fastest way to get an answer is to mail the course's Google group https://groups.google.com/forum/#!forum/tda357-vt2018

Google Group

If you have any general questions regarding the course, the labs or the exercises, please ask them in our Google group https://groups.google.com/forum/#!forum/tda357-vt2018 This will reach all teachers and fellow students.

We have made the group public, so that you don't need to ask for a membership.

Laboration times and supervision

See Time Edit for times and places.

Course assistants will be in the lab rooms to help.

Attendance in these classes is optional. Normally, each student should attend at most one supervised laboration time each week.

Assignments

There are three assignments (a.k.a. "laborations", "labs"), written individually or in pairs. In addition, there is a "Lab 0", which consists of just registering the group.

The specification ("lab PM") is here

Reporting is done via Fire Before reporting assignments 1 and 2, you must run your program through a test suite.

The final deadline is Sunday 18 March for all returned and corrected labs. No labs will be graded if sent after this deadline.

We guarantee two gradings per lab: one for the version submitted before the ordinary deadline for that lab, the other for a resubmission before the final deadline. If your first submission is after the lab deadline, only one grading is guaranteed.

Labs are by default done in pairs:

Literature

The official course book is

Book web page

A new "international edition" was published in summer 2013. The chapters relevant to this course are the same, so either version will be OK. The book is available at Cremona and at web bookshops.

You can also use an on-line book manuscript, referred to as "notes": Databases in 88+ pages. Our plan is to publish these notes as a short course book later, and your feedback will be appreciated!

Exercises

There are six exercise sessions. Each session is given two or three times; you are supposed to participate at most once at each session.

See Time Edit for exact times and places.

The questions will be posted a few days before each class. The answers will be posted after each class, to encourage everyone to try the exercises themselves.

Exam

Written exam, usual grading scales.

Date: Friday 16 March

Time: 8:30 - 12:30

Place: TBA (Johanneberg)

The exam has a similar structure as these old exams.

The exam questions contain a standard cheatsheet, which is a reference card covering all E-R, SQL, relational algebra, and XML syntax that is needed in the exam.

Exam review: 20 April at 14-16 in EDIT room 6106

Software

PostgreSQL https://www.postgresql.org/ (the main software, used in assignments). Practical help about using the school's Postgres installation can be found in these PostgresTips.

Query Converter, available as a web application soon. Source: https://github.com/GrammaticalFramework/gf-contrib/tree/master/query-converter This is experimental teaching software developed to accompany the notes.
