Infrastruktur yang biasa digunakan oleh sistem informasi yang ada di Indonesia kebanyakan mempunyai model yang terpusat. Sehingga, jika terjadi masalah pada server seperti server mati atau terjadi kerusakan pada basis data, maka sistem informasi tidak dapat digunakan sampai masalah pada server tersebut teratasi. Untuk mengatasi hal tersebut, sistem replikasi atau duplikasi data pada sistem basis data terdistribusi diharapkan dapat meminimalisir kehilangan data rekam medis sehingga walaupun ada server yang mengalami masalah, maka data tidak akan hilang. Dalam konteks sistem rekam medis di poliklinik UIN Sunan Kalijaga, hal ini bisa menjadi solusi untuk memenuhi aspek ketersediaan data. Sinkronisasi data antara server utama dan replika dapat dilakukan secara otomatis maupun secara manual. Sinkronisasi otomatis dilakukan dengan cara menjalankan baris program secara otomatis dan berkala dengan aturan tertentu. Sinkronisasi manual dijalankan oleh operator dengan menjalankan suatu perintah. Berdasarkan hasil dan pembahasan, diperoleh kesimpulan bahwa implementasi Heterogenous Distributed Database System pada sistem informasi poliklinik dapat mengatasi masalah jika terjadi pada beberapa server dengan cara mengolah dan mendisribusikan data pada server lain yang aktif. Proses replikasi dan sinkronisasi data rekam medis yang dilakukan, ternyata dapat meminimalisir kehilangan data.Infrastructure used by the existing information systems in Indonesia, mostly have a centralized model. Thus, if a problem occurs on the server as the server is dead or there is damage to the database, the system information can not be used until the problem is solved on the server. To overcome this, the system replication or duplication of data in a distributed database system is expected to minimize the loss of medical records so that even if there is a server that has the problem, then the data will not be lost. In the context of medical records system at the clinic UIN Sunan Kalijaga, this could be a solution to meet aspects of data availability. The data synchronization between the primary and replica servers can be done automatically or manually. Automatic synchronization is done by running the program line automatically and periodically with certain rules. Manual synchronization is run by an operator to execute a command. Based on the results and discussion, we concluded that the implementation of heterogenous Distributed Database System on clinic information systems can solve the problem if it occurs on multiple servers by processing and mendisribusikan data on another server that is active. The process of replication and synchronization of medical records that do, it can minimize data loss.

The distributed database system is the product that the database system combines with the computer network system. The data distribution problem has great influence on distributed database application system improvement, data availability, the efficiency and reliability of the distributed database. The allocation strategies in this paper have used some excellent properties in genetic algorithms, including higher parallelism and robustness, the realization of standard way, and to maintain good balance between the depth prior search and breadth prior search, etc, so the allocation strategies in this article's have high execution efficiency, with stronger ability in seeking the best global solution and easy to realize.

Media information through the Internet is growing rapidly and incessantly. This is one manifestation of the development of information systems technology is so rapid. An information transmitted between a database with another database that allows to interact in a distributed database system. In Raharja College, students are trained to produce scientific work such as paper, the report KKP/TA / SKRIPSI. Widuri is the place of manufacture and storage of the report KKP/TA / SKRIPSI College Prog. This is one manifestation of the development of information systems technology is so rapid that affect the world of education. College Prog has an official website that raharja.ac.id as a variety of information in colleges raharja to optimize the website raharja acid in her integration into the data on the website widuri acid raharja website in order to facilitate students in accessing scientific papers reporting data
