By analyzing the daily work of Data Base Administrators (ABD), we perceived that a large amount of problems (e. g. performance tuning, security and physical dimensioning) occur repetitively. Nonetheless, the professionals normally forget the best solution for them, especially whe...
Ver documentoCurrently the Database Management System (DBMS) possess great capacity to store since the data gotten for the systems do business until the information synthecized for the systems of decision taking. In this context, as much the search for the information how much the routines of...
Ver documentoA process for the database management system (DBMS) choice in the forward engineering stage, in an object-oriented reengineering is presented. The process was instanced for two particular DBMSs Jasmine and Caché, which a forward engineering case study was developed. The legacy sy...
Ver documentoOne of the biggest challenge of building and maintaining applications with long life cycles is dealing with the inevitable changes in requirements that occur over time. Many of these applications depend on DBMS that most often suffer direct consequences in their databases schemas...

Ver documentoThe spatial data complexity justifies the need to develop new spatial data types and to design new structures to store, to query and to handle spatially referenced data inside a database management system (DBMS). This work presents an analysis of these issues considering the diff...
Ver documentoThe complexity of data stored in large databases has increased at very fast paces. Hence, operations more elaborated than traditional queries are essential in order to extract all required information from the database. Therefore, the interest of the database community in similar...
Ver documentoThe use of computers by an increasing variety of applications led the Database Management Systems (DBMS) to be used to store a wide range of complex data types, such as images, sounds, DNA chains, etc. Queries based on the total order relationship and/or equality can not be appli...
