Perkembangan perangkat lunak computer dewasa ini terjadi sedemikian pesatnya, perkembangan tidak hanya terjadi pada perangkat lunak yang memiliki lisensi tertentu, perangkat open source pun demikian. Perkembangan itu tentu saja sangat menggembirakan bagi pengguna computer khususnya di kalangan pendidikan maupun di kalangan mahasiswa, karena pengguna mempunyai beberapa pilihan untuk menggunakan aplikasi. Perangkat lunak open source juga menawarkan produk yang umumnya gratis, diberikan kode programnya, kebebasan untuk modifikasi dan mengembangkan. Meneliti aplikasi berbasis open source tentu saja sangat beragam seperti aplikasi untuk pemrograman (PHP, Gambas), Database Management System (MySql, SQLite), browsing (Mozilla, Firefox, Opera). Pada penelitian ini di kaji penerimaan aplikasi DBMS (Database Management System) seperti MySql dan SQLite dengan menggunakan sebuah model yang dikembangkan oleh Venkantes(2003) yaitu UTAUT (Unified Theory of Acceptance and Use of Technology). Faktor – faktor tertentu juga mempengaruhi dalam melakukan kegiatan pembelajaran aplikasi open source ini, salah satu faktor atau yang disebut dengan moderating yang bisa mempengaruhi efektifitas dan efisiensi. Dengan demikian akan mendapatkan hasil yang bisa membuat kelancaran dalam pembelajaran aplikasi berbasis open source ini.   Kata kunci— open source, Database Management System (DBMS), Modereting

Relational Database Management

This chapter is focused in incorporating the fuzzy capabilities to a relational database management system (RDBMS) of open source. The fuzzy capabilities include connectors, modifiers, comparators, quantifiers, and queries. The extensions consider a more flexible DDL and DML languages. The aim is to show the design and implementation details in the RDBMS PostgreSQL. For this, a fuzzy query processor and fuzzy access mechanism has been designed and implemented. The physical fuzzy relational operators have been also defined and implemented. The flow of a fuzzy query through the different modules (parser, planner, optimizer, and executor) has been shown. Some experimental results have been included to demonstrate the performance of the proposal solution. These results show that the extensions have not decreased the performance of the RDBMS.

Database Management System

Perkembangan teknologi informasi dan data meningkat pesat di era big data seperti sekarang ini. Database Management System menjadi bagian utama yang sangat penting untuk mengontrol arus data. Penelitian ini membandingkan kinerja web server yang menggunakan RDBMS open source yang berbeda antara MySQL dan MariaDB. Pengujian dilakukan pada Oracle Virtual Machine Virtualbox menggunakan ApacheBench untuk mengukur kinerja Web Server pada SIM Manajemen Diklat Poltekpel Sorong. Hasil percobaan menunjukkan bahwa web server ketika menggunakan RDBMS MySQL cenderung memiliki performa yang cukup stabil ketika permintaan akses web di bawah 300 kali secara bersamaan yaitu pada 100,200 dan 300 kali berturut-turut sebesar 7.764/ms, 16.386/ms dan 30.025/ms. Namun, saat permintaan akses web di atas 300 secara bersamaan RDBMS MariaDB justru menunjukkan kinerja yang lebih baik. Hal ini ditunjukkan dengan permintaan akses 400 dan 500 kali web server secara bersamaan, waktu respon terlihat lebih cepat dibandingkan ketika menggunakan RDBMS MySQL berturut-turut sebesar 51.877/ms dan 54.702/ms sedangkan RDBMS mariaDB untuk permintaan akses web server secara bersamaan pada 100,200,300,400 dan 500 berturut-turut sebesar 14.213/ms, 25.642/ms, 40.831/ms, 48.021/ms dan 51.630/ms

AbstractAn object-oriented medical database management system is presented for a typical cardiologic center, facilitating epidemiological trials. Object-oriented analysis and design were used for the system design, offering advantages for the integrity and extendibility of medical information systems. The system was developed using object-oriented design and programming methodology, the C++ language and the Borland Paradox Relational Data Base Management System on an MS-Windows NT environment. Particular attention was paid to system compatibility, portability, the ease of use, and the suitable design of the patient record so as to support the decisions of medical personnel in cardiovascular centers. The system was designed to accept complex, heterogeneous, distributed data in various formats and from different kinds of examinations such as Holter, Doppler and electrocardiography.
