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:

Abstract (eng): Since the first databases were developed, the standard application setup has been a centralized database providing data access to multiple clients.
However, decentralized organizations and ever-growing computer networks provide an opportunity and a demand for distributed databases.
Modifying existing applications,. designed to work with a centralized database, to work with a distributed database is usually complicated and requires cumbersome changes and thorough verification.

This master's thesis describes how an existing data access layer, designed to be used with centralized databases, is extended with a new framework to add support for distributed databases.
By placing the changes within the data access layer, changes in existing applications are minimized.
The different constraints and requirements of distributed database environments are taken into account in the design of the framework by providing a modular solution.
