Converting time series data for information systems integration

Most enterprises have an autonomous and heterogeneous information system. The same data may be diversely represented in different information systems. The core of solutions for integrating heterogeneous data sources is data conversion. One of the major issues of data conversion is how to convert data that contains temporal information. In this paper I propose a method to effectively convert time-series data appearing in enterprises. The concept of calendar is integrated into the proposed method. The method is based on a generalized representing form for data. The converting operations and processes are defined and presented.
