Database and Information Systems
News
20.3.2019 - The solution of the test is presented here. The repair of the test will be on practise 26.3.2019.
Credit conditions
Student has to pass one test from procedural languages PL/SQL. Minimimal number of points is 8 and maximal 15. At most two attempts of the test will be possible. Another part of the credit is a home project which is focused on a analysis and implementation of an information system under platform .NET or Java.
Real time test
Real time test from PL/SQL will be in 5th week. Student can use any type of materials during the test (except the social networks and the communication with other people).
Model for the test from PL/SQL
The test will use the following data model. Run this script to create the tables in your database. Last update of the script: 6.3.2019 14:20.
Model for the real test (from the last years)
- Data Model: pdf (last change: 16.3.2018), scripts:
- Data Model: pdf (last change: 21.3.2017), scripts:
The real time tests with the solutions are presented here, here, and here.
Project
Project should be defended in the last week. Student can implement the chosen project under platform .NET or Java.
Requirements:
- IS will have at least 7 tables and 5 non-trivial methods. At least 3 methods will be implemented as stored procedures.
- At lest 3 of the implemented non-trivial methods will be as transactions. Non-trivial method is not CRUD command.
- Cascade delete is not allowed as a non-trivial method.
- The implementation has to follow the analysis.
- The architecture has to contain layers. Data layer has to contain own Object-Relation Mapping (ORM)
- Student can implement in ASP.NET or J2EE (in the case of web application) or .NET or Java (in the case of desktop application).
- ORM will support also lazy evaluation and update only changed attributes.
- ORM will support transaction (at least level of isolation SERIALIZABLE).
- A part of ORM will be a test method utilizing all methods of ORM.
- IS will support basic validation of input values.
- Only two forms of the IS have to be implemented. The forms will be chosen by a teacher according to the analysis. The forms have support basic validation of input values.
- The complete project has to contain documentation with analysis, SQL scripts and implementation.
- Example analysis of the project here
- Example ASP.NET project here
Evalution of the project:
- Analysis: 10 points, min. 6 points (1. submission 10 points, 2. submission 8 points, 3. submission 6 points)
- ORM: 10 points, min. 5 points
- IS: 10 points, min. 5 points
