Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): Object-oriented programming is perhaps the most popular programming paradigm, whereas the data storage used is most likely a relational database.
Even if these two paradigms in no way contradict each other, their fundamentally different approaches sometimes cause problems.
Applications without a well defined data access layer easily end up having a substantial amount of code dedicated to the sole purpose of moving data from and to the data source.

This thesis defines a model based data access layer, where an abstract model of the data structure is created using objects within the application domain.
This thesis shows how that model can be utilized to overcome the gap between an object-oriented programming environment and a relational database.
Furthermore it shows how having this modularized framework simultaneously makes it easier to create more robust applications.
The framework has also proved to be an excellent platform for building reusable libraries upon, enabling faster application development.
