International Journal of Data Science (IJDS), Vol. 1, No. 1, 2015

Abstract: Relational database supports primitive values in a relation. However, complex applications require compound values. Object-oriented database supports these complex applications using nested objects. This means that an object can have another object inside it. In nested objects, queries in an object-oriented database require traversing from one object to another object. In this paper, a novel method is proposed for traversing which uses objectIds and classIds. This algorithm is straightforward and therefore effortlessly traverses through the nested objects in a given query. Use of objectIds, classIds and the relationship between classes makes this algorithm very simple. An implementation based on the C#.NET demonstrates the strength of the outcome. The new approach cuts down the processing costs over conventional algorithms.
