Database Report

The database report introduction database includes a series of information organized so that the computer program can quickly select the data. The database can be thought of as an electronic file system. A field is a single piece of information, a record is a series of fields, and a file is a collection of records. For example, a phone book is similar to a file. It contains a list of records, and each record needs to access information from the database. A database management system is required.

The database contains original research, editorials, reports, and review articles from various journals. According to reports, the most commonly used databases for students are British nursing index, MEDLINE, and Cochrane Library (see Table 1) (Ely & Scott, 2007, p. 61). Google Scholars and Cochrane Library are used to some extent to supplement database searches. In addition to searching the database, many valuable references were found by manual search, but this method was time consuming and the scope of the project was limited. The availability of online journals and databases on the Internet has proven to be a better choice for finding the data you need.

Preliminary literature search was conducted on the following databases: JBI database evaluation and implementation report database, Cochran systematic review database, PROSPERO international system evaluation expectation database, health effectiveness evaluation promotion database (DoPHER) and Epistemonikos, they are still published The subjects that have not confirmed that they are present are systematic or scope. The review is registered in the JBI Systematic Review Database (May 5, 2017). The scoping review will begin in September 2017 and data extraction will be completed in November. Our goal is to submit the peer review results in manuscript form by the end of January 2018 for peer review.
