Database System Of The Single-particle Effects

The paper focuses on technology of database and object oriented program language that is applied for single event effect. The first part of the paper introduces some background and theoretical knowledge concerned with the System of Single Event Effect Database. It includes some knowledge of single event effect, database and object oriented program language. It proves that it is necessary and feasible to develop the System of Single Event Effect Database. The second part is the body of the paper, and it mainly discusses the developmental progress of the System of Single Event Effect Database. It detailedly introduce system structure, design of database, design of application program, functions of system, security of system. The system structure is based on the client/server. The application program is installed in the client computer and the database is installed in the server. The design of database complies with the principles of safety and all-sides, and its data types include all the parameters that are likely to describe the single event effect. Design of database integrity and backup & restore are discussed in this section, too, to maintain the data safety of database. The application program is based on document/view structure. It specially aims on the object oriented program language, and its promincnt advantage is that it can be developed and expanded conveniently. System functions include data querying data, maintaining database, printing, backuping and restoring database, users management. System security discusses the methods that prevent the system from being attacked from illegal users.
