Therefo re, Hotel Management Information System (HMIS) has been developed to overcome these limitations of manual system. Searching of record in the manual working is very slow and cumbersome.

Manual systems have been restricted with limitations, like space to store and slow working speed. Hotel Management Informat ion System keeps record of hotel guests and has fa cilities for booking, making reg istrations and posting of bills and entering roo m hotel rates etc. Once all the databases are connected through heterogeneous gateway, user will be able to access data and process distributed transactions efficiently from Oracle.

Even user need not have to worry about the location of database. Oracle user will neither have to bother about architecture nor commands of the remote databases from where data is accessed. The successful implementation of data access from multiple heterogeneous databases provides very easy and efficient access of data in Oracle using its native language/commands. In this paper, the procedure to connect four heterogeneous databases namely PostgreSQL, MySQL, Oracle and MS Access is described. The data access and distributed transaction execution is made very easy through this gateway. Oracle DBMS provides heterogeneous gateway service to connect oracle and non-oracle databases. There are several methods of data access from distributed database, still it involves complicated implementation of these methods. In distributed database, the physical database is distributed across heterogeneous database systems.

One of the challenges is obtaining database transparency. Challenges and issues of distributed database are well known.
