Local or External Databases in Android Programming. A Practical Comparative Study

Abstract

Currently, databases are used in the programming process of software applications. In a computer machine, a database associated to a software application can be localized either at the local or at external level. This paper aims to present, analyze and discuss various methods used to access and operate both the local and external databases from Android programming code and also to provide concrete examples in this respect. An Android software application that simulate the virtual class book has been developed. An external database is used for data storage. The advantages and disadvantages of using both database types are presented
