AbstractWith the growing amount of research projects in the field of interventional radiology, storing and organizing the patients' data and information effectively is becoming more difficult. Existing hospital electronic medical record and archiving systems store patient information in the form of reports which put the physicians and researchers in a situation where they have to use time-consuming manual search through reports for suitable patients for different clinical researches. Spreadsheet programs such as Microsoft Excel® (Microsoft, Washington, USA) are often used as a data storage, which has limitations in both organization and the quality of the data. Higher risk of incorrect data entry and introducing duplicates are associated with data input and analysis without a database system. Furthermore, selection, as well as calculation of data, is time-consuming. This article aims to provide interventionists with an efficient data collection tool optimized for interventional oncology clinical research. The implementation of the current database and interface allows a much faster and more detailed retrospective analysis of patient cohorts. The database management system with an interface is a very time-efficient and robust tool that provides a significant edge over the manual retrieval of patient records by filtering data and assisting statistical analysis in a study-relevant fashion.

Relational Data Model

A database management system is a constant application of science that provides a platform for the creation, movement, and use of voluminous data. The area has witnessed a series of developments and technological advancements from its conventional structured database to the recent buzzword, bigdata. This paper aims to provide a complete model of a relational database that is still being widely used because of its well known ACID properties namely, atomicity, consistency, integrity and durability. Specifically, the objective of this paper is to highlight the adoption of relational model approaches by bigdata techniques. Towards addressing the reason for this in corporation, this paper qualitatively studied the advancements done over a while on the relational data model. First, the variations in the data storage layout are illustrated based on the needs of the application. Second, quick data retrieval techniques like indexing, query processing and concurrency control methods are revealed. The paper provides vital insights to appraise the efficiency of the structured database in the unstructured environment, particularly when both consistency and scalability become an issue in the working of the hybrid transactional and analytical database management system.

The Zone Logic Technology CAD/CAM and networked Database Management System is an integrated system of commercially available, off-the-shelf computer hardware and software products. These products have been carefully selected, tailored, and integrated to specifically satisfy and support the Philadelphia Naval Shipyard (PNSY) Zone Technology Program in support of work packaging development, computer-aided graphics and an on-line, real-time, distributive database management system. The process used in publishing this paper serves as a small example of some of the capabilities of the system at PNSY. The entire document, including graphics, was generated on the system. Scanners, CAD and PC systems were utilized to input, develop and convert the graphics files into appropriate formats for import into a technical publications software package. LAN interconnection capabilities provided the option of developing portions of this document on different systems and at different locations with the ability to access the appropriate files remotely.

Access To Data

Abstrak. Data cuaca berupa suhu udara, kelembaban udara, curah hujan, dan kecepatan angin memerlukan proses penyimpanan yang baik supaya data cuaca dapat direkapitulasi selama satu tahun. Untuk itu membutuhkan proses penyimpanan data melalui Database Management System (DBMS). DBMS dapat mengelola, menyimpan sekumpulan data secara baik. Pengguna DBMS dapat membuat, mencari, memelihara, serta memiliki akses terkontrol terhadap data. Penyimpan data pada pemantauan cuaca menggunakan hardisk eksternal dalam format Comma Separated Values (CSV), penyimpanan data seperti ini kurang efisien diakibatkan data direkapitulasi secara manual ke dalam computer. Kinerja sinkronisasi database dianalisis menggunakan metode Event-Driven dan Time-Driven pada DBMS Oracle dan MySQL untuk pemantauan data cuaca. Hasilnya, pada saat proses penyimpanan 100 data (record), MySQL memiliki kemampuan yang lebih cepat yaitu 166 detik dibandingkan dengan Oracle dalam waktu eksekusi 188 detik. Pada saat proses penyimpanan mulai 200 sampai 1000 data (record) membutuhkan waktu eksekusi rata-rata pada Oracle yaitu 203,56 detik sedangkan pada MySQL waktu eksekusi rata-rata 1163,89 detik. Jadi, kinerja DBMS Oracle lebih baik dibandingkan dengan DBMS MySQL dalam proses penyimpanan data cuaca, namun DBMS Oracle belum bisa menyimpan data secara langsung dari mikrokontroler karena belum adanya program yang mendukung ke dalam DBMS Oracle. Abstract. Weather data in the form of air temperature, humidity, rainfall, and wind speed require a good storage process so that weather data can be recapitulated for one year. For this reason, it requires the process of storing data through a Database Management System (DBMS). DBMS can manage, store a collection of data well. DBMS users can create, search, maintain and have controlled access to data. Data storage in weather monitoring uses an external hard drive in Comma Separated Values (CSV) format, this kind of data storage is less efficient due to the data being recapitulated manually into a computer. Therefore, the author wants to analyze the performance of database synchronization on Oracle and MySQL DBMS by using Event-Driven and Time-Driven methods for monitoring weather data. As a result, when storing 100 data (records), MySQL has a faster capability of 166 seconds compared to Oracle in 188 seconds of execution time. When the storage process starts from 200 to 1000 data (records) the average execution time in Oracle is 203.56 seconds, while in MySQL the average execution time is 1163.89 seconds. So, the performance of the Oracle DBMS is better than the MySQL DBMS in the process of storing weather data, but the Oracle DBMS has not been able to store data directly from the microcontroller because no program supports it into the Oracle DBMS.

As the mobile applications are constantly facing a rapid development in the recent years especially in the academic environment such as student response system (Lópeza, Royoa, Labordab, & Calvoa, 2009; Ngai & Gunasekaran, 2007; Mary & Biju, 2008; Nayak & Erinjeri, 2008; Roth, Ivanchenko, & Record, 2008; Lu, Stav, & Pein, 2009; Lu, 2009; Turning Technologies, 2010) used in universities and other educational institutions; However, an effective and scalable Database Management System to support fast and reliable data storage and retrieval is missing. This paper presents Database Management Architecture for an Innovative Evaluation System based on Mobile Learning Applications. The need for a relatively stable, independent, and extensible data model for faster data storage and retrieval is analyzed and investigated. Finally a case study to prove the concept of the urgent need for the system is proposed. It concludes that the system is important by emphasizing further investigation to support multimedia data types, such as video clips, images and documents in near future.
