Аннотация: We present a new project - SAI CAS (Sternberg Astronomical Institute Catalog Access Services). The goal of this project is to provide the Russian and international community with online access to major large astronomical catalogs (USNO-A2.0/B1.0, SDSS, 2MASS, GSC I/II, DENIS, UCAC) and provide tools and services facilitating scientific research using these catalogs. Currently SAI CAS is the largest astronomical data center in Russia. It provides primary services such as cone search, cross match between catalogs inside a region on the sky, and between system and user catalogs, etc. Several science projects in Russia already use SAI CAS. The SAI CAS project is based on open source software and is an open source itself. The system uses relational database storage (PostgreSQL), where all data and metadata are stored. The spatial searches and cross matches are performed using the Q3C plugin for PostgreSQL. Our system can be accessed via web-services (SOAP and simple HTTP POST/GET) and web interfaces. The SAI CAS project is located at http://vo.astronet.ru.
