Rdesign: A data dictionary with relational database design capabilities in Ada
Data Dictionary is defined to be the set of all data attributes, which describe data objects in terms of their intrinsic attributes, such as name, type, size, format and definition. It is recognized as the data base for the Information Resource Management, to facilitate understanding and communication about the relationship between systems applications and systems data usage and to help assist in achieving data independence by permitting systems applications to access data knowledge of the location or storage characteristics of the data in the system. A research and development effort to use Ada has produced a data dictionary with data base design capabilities. This project supports data specification and analysis and offers a choice of the relational, network, and hierarchical model for logical data based design. It provides a highly integrated set of analysis and design transformation tools which range from templates for data element definition, spreadsheet for defining functional dependencies, normalization, to logical design generator
SISTEM PENGOLAHAN TRANSAKSI PADA PT. SABA INDOMEDIKA JAYA PALEMBANG
The research objective was to design a transaction processing system that uses a data
base so as to facilitate, accelerate and reduce the level of error in the processing of
sales data.
The research method used by writer is method consists of iterations of the system
survey and design stage. Phase system survey conducted by surveying the system
running, conducting interviews and collecting data to obtain the needed information,
conduct and analyze the scope of the problems with using the PIECES. In the design
phase is done by creating a logical system design and physical systems, program
design and determine the schedule of implementation of the system.
The results of the survey system and transaction processing system design is expected
to be forwarded to the implementation phase so that the system can be applied for
purposes of sale of PT. Saba Indomedika Jaya Palembang. With the existence of this
system is expected to address the problems that exist in the processing of sales data
and speed up the search data items needed to improve the services provided by PT.
Saba Indomedika Jaya Palembang to its employees
Towards Automating the Construction & Maintenance of Attack Trees: a Feasibility Study
Security risk management can be applied on well-defined or existing systems;
in this case, the objective is to identify existing vulnerabilities, assess the
risks and provide for the adequate countermeasures. Security risk management
can also be applied very early in the system's development life-cycle, when its
architecture is still poorly defined; in this case, the objective is to
positively influence the design work so as to produce a secure architecture
from the start. The latter work is made difficult by the uncertainties on the
architecture and the multiple round-trips required to keep the risk assessment
study and the system architecture aligned. This is particularly true for very
large projects running over many years. This paper addresses the issues raised
by those risk assessment studies performed early in the system's development
life-cycle. Based on industrial experience, it asserts that attack trees can
help solve the human cognitive scalability issue related to securing those
large, continuously-changing system-designs. However, big attack trees are
difficult to build, and even more difficult to maintain. This paper therefore
proposes a systematic approach to automate the construction and maintenance of
such big attack trees, based on the system's operational and logical
architectures, the system's traditional risk assessment study and a security
knowledge database.Comment: In Proceedings GraMSec 2014, arXiv:1404.163
