13. Mutation analysis for SQL database applications / Analise de mutantes em aplicações SQL de banco de dados
Testing database applications is crucial for ensuring high quality software as undetected faults can result in unrecoverable data corruption. SQL is the most widely used interface language for relational database systems. Our approach aims to achieve better tests by selecting fault-revealing databases. We use mutation analysis on SQL statements and discuss t

14. MD-JPA : um perfil UML para modelagem do mapeamento objeto-relacional com JPA em uma abordagem dirigida por modelos / MD-JPA:a UML profile for object relational mapping with JPA in a model driven approach
A abordagem de desenvolvimento dirigido por modelos (DDM) propõe que modelos (e transformações entre modelos) assumam o papel principal no desenvolvimento de sistemas. Entretanto, não há uma notação consensual para modelagem de persistência baseada em arcabouços de mapeamento objeto-relacional: enquanto a UML não possui recursos específicos para a

15. EstereÃtipos e princÃpios de projeto para mapeamento entre esquemas de classes de sistemas e esquemas de banco de dados utilizando o paradigma objeto â relacional / Stereotypes and principles of project for mapping from class schemas to da tabase schemas utilizing object-relational paradigm
O presente trabalho aborda a especificaÃÃo de princÃpios de projetos para mapeamento de Esquema de Classes de Sistemas, baseados no Modelo de Classes da UML, para Esquemas de Banco de Dados (i.e. Esquema Conceitual, LÃgico e FÃsico), a serem implementados utilizando os recursos existentes nos Sistemas de Gerenciamento de Banco de Dados (SGBD) baseados n

16. SYSTEM FOR KEYWORD SEARCH IN RELATIONAL DATABASE / SISTEMA PARA CONSULTAS SOBRE BANCO DE DADOS RELACIONAL BASEADO EM PALAVRAS-CHAVE
This dissertation describes a developed system that allows the creation and execution of searches from keywords in a relational database. The system receives any keywords and tries to create queries that can be executed in database. To perform this automatic generation of queries the system uses the information of the catalogue of the source database. The sy

17. RELATIONAL DATABASE HYBRID MODEL, OF HIGH PERFOMANCE AND STORAGING CAPACITY, FOR NUCLEAR ENGINEERING APPLICATIONS / Modelo híbrido de banco de dados relacional, de alto desempenho e capacidade de armazenamento, para aplicações voltadas à Engenharia Nuclear
The objective of this work is to present the relational database, named FALCAO. It was created and implemented to support the storaging of the monitored variables in the IEA-R1 research reactor, located in the Instituto de Pesquisas Energéticas e Nucleares, IPEN CNEN/SP. The data logical model and its direct influence in the integrity of the provided inform

18. Celine: um modelo para utilização e adaptação de conteúdo scorm em ambientes inteligentes de aprendizagem
The effort to maintain contents in ILE (Intelligent Learning Environments) was the inspiration behind the development of this work. It was observed that the contents to be taught are heavily reliant on these environments, which makes their sharing with other systems difficult. In addition, these materials are created with internal tools, which offer few reso

19. Transformação de modelos orientados a objetos em modelos de banco de dados objeto-relacional
In general, software systems implemented based on Object Oriented (OO) concepts persist their information in Relational Database (RDB) and more recently in Object Relational Database (ORDB), which support the OO paradigm concepts. Therefore, it is common to use OO Models for software system requirements specification whose information are persisted in ORDB.

20. Implementation of a plant-associated bacteria proteome database:ProBacter / Implementação de um banco de dados de proteomas de bactérias associadas a plantas: ProBacter
This dissertation offers a computation approach to comparative analysis between cmpletely sequenced genomes of plant-associated bacteria. The created system was denominated ProBacter and it is composed of a relational database and computational tools for sequence analysis. The database was created from a diverse data source, including information from GenBan

21. Satisfação, lealdade e retenção: um pré-experimento aplicado à telefonia móvel
Satisfaction and loyalty of those faithful consumers to a specific product or brand name are interconnected in a complex way, and, just like CEOs, marketing and statistics academic professionals understand and admit this close relation as well, by publishing some researches which point out the consumers satisfaction as an antecedent of loyalty. However, more

23. GRAPHIC SIMULATION OF CORN GROWTH / SIMULAÇÃO GRÁFICA DO CRESCIMENTO DE PLANTAS DE MILHO
The computer graphic simulation can be used to understand plant growth and development influenced by biotic or abiotic parameters. The main simulation purposes are: (i) to predict plant agronomic characteristics when its submitted to different climatic, environmental, and physical factors; (ii) to analyze the influence of these factors in plant growth and de

24. RECRIAÇÃO AUTOMÁTICA DE ÍNDICES EM UM SGBD RELACIONAL / AUTOMATIC REINDEXING IN RELATIONAL DATABASES
One of the most important tasks of Database Administrators certainly is to guarantee optimal response times to statements submitted by users of big RDBMS. Our dissertation deals with Index Self-tuning, which means creating, dropping or recreating indexes automatically, in order to decrease SQL queries durations. We start from Marcos Salles´ dissertation [32
