An Object-Oriented Database for Project Cost Compilation

Larger construction companies generally have several on-going projects at one time, many internationally. The ability to make corporate decisions in a timely manner for these companies becomes critical to avoid costly corrective measures. The information necessary for making such decisions comes from a large pool of corporate data. In order to efficiently process large amount of data, an information model for multiple project management is essential.

In this research, an information model based on Cost is designed and presented (OCIM, Object-oriented Cost Information Model). A prototype system is developed based on the model using an object-oriented database. Using the periodical update feature of the prototype system, an immediate access to necessary information by the user is made possible. The different levels of information abstraction are also achieved to meet the different level of the user.
