Many astronomers need some catalogs to choose source candidates, do identification and research. At present, some large data centers aboard provide such services as catalogue query, multiple source query (i.e. cross-identification of small sample) and visualization. However, with the increase of observational data and the arrival of the whole wavelength astronomical era, the present services can not meet some requirements from astronomers. We review the services of data centers abroad, put new problems and raise a set of solutions. The realization of the cross-identification, and free choice of parameters so on are all emphasized.
