Abstract

This thesis should yield a system that is capable of providing access to documents. Such documents and the file access thereto are of central importance. The access to these documents should not be limited by a single interface or access manner. Databases and database management systems (DBMS) using the Structured Query Language (SQL) and following the ACID paradigm are commonly used to manage data. Such databases are robust and performant but minimize flexibility regarding the data structure, as it has to be determined at the creation of a system and should not be changed over time. Additionally, the data can only be accessed by the database management system (DBMS). Hence, the data cannot be accessed if the database management system is not running, because in major systems like MySQL, PostgreSQL or DB2 the data is stored in a binary manner to increase performance. As this thesis aims to provide a system wherein access is independent of single components, especially of the database server such traditional SQL servers cannot be used. Moreover, single data attributes can not be inserted, in performance-oriented SQL servers, even if the DBMS was not running as it would require knowledge over the internal database structure, as well as complex insertion and modification methods, whereas the focus should lie on the documents, their consistency, rather than on the meta information. In consideration of these goals, the implementation of a system with multiple access strategy and easy modification will be discussed in the following chapters of this thesis.
