The construction of characteristic database is a systematic project, including planning, demonstration, collection, sorting, processing, classification, web page construction and maintenance, as well as some technical problems. In the construction of this system engineering, we must first strictly check the source, that is, we must have a scientific and rigorous attitude in the planning and demonstration stage at the beginning of database construction, and submit a feasibility report on the basis of a comprehensive understanding of the overall situation of characteristic database construction.
1, the topic should be rigorous.
At present, the phenomenon of low-level repeated construction, lack of characteristics and slow updating in the construction of characteristic databases is quite common. As a university library, it is necessary to define the scope and do something different, so as to find its own position and build a school with university characteristics. Characteristic database with sustainable development potential. Therefore, to develop the characteristic database, we must first choose the right topic and do a good job in the demonstration of the project. On the basis of careful investigation of the distribution of database information resources at home and abroad, the appropriate subject range or literature type range should be determined according to the characteristics of collection, the setting of key disciplines and the needs of users. Don't blindly seek "big" and "complete", but demand "fine" and "expert", that is to say, the content should not be too complicated. Don't be too broad, focus on a certain field, and collect valuable things in this field as much as possible to reflect the theme and uniqueness of the database.
2. Data sources should be collected comprehensively.
Data is the core of database, and data quality is the quality of database in a sense. Therefore, data acquisition is a very important link in database construction. In order to ensure the integrity and authority of the collected information, we should mainly pay attention to the following aspects:
(1) Determine the reasonable collection scope, including subject scope, time limit scope, geographical scope, language scope, etc.
(2) Determine the types of information sources, including books, periodicals, conference proceedings, papers, patent documents, product descriptions, scientific and technological reports and online information;
(3) Determine the form of information, including words, tables, pictures, animations, music and multimedia information.
