ABSTRACT
Database administration has gained an essential role in the management of new database technologies. Different data models are being created for supporting the enormous data volume, from the traditional relational database. These new models are called NoSQL (Not only SQL) databases. The adoption of best practices and procedures, has become essential for the operation of database management systems. Thus, this paper investigates some of the techniques and tools used by database administrators. The study highlights features and particularities in databases within the area of Brasilia, the Capital of Brazil. The results point to which new technologies regarding database management are currently the most relevant, as well as the central issues in this area.

ABSTRACT
The purpose of this paper is to analyze the level of system integration among organizations that have deployed intranets or portals. In spite of being independent technologies, portals and EAI have in common the integration issue, and the combined usage of both may produce the synergic effect on application integration processes. The paper presents an instrument to analyze the integration level and the PMM (Portal Maturity Model) which can be used to assess the contributions of intranets and portals to Knowledge Management initiatives. According to the identified issues, this study suggests some guidelines for system integration projects.

ABSTRACT
This paper is focused on receivables management and possibilities how to use available information technologies. The use of information technologies should make receivables management easier on one hand and on the other hand it makes the processes more efficient. Finally it decreases additional costs and losses connected with enforcing receivables when defaulting debts occur. The situation of use of information technologies is different if the subject is financial or non-financial institution. In the case of financial institution loans providing is core business and the processes and their technical support are more sophisticated than in the case of non-financial institutions whose loan providing as invoices is just a supplement to their core business activities. The paper shows use of information technologies in individual cases but it also emphasizes the use of general results for further decision making process. Results of receivables management are illustrated on the data of the Czech Republic.

ABSTRACT
The dimensional growth and increasing difficulty in project management promoted the development of different tools that serve to facilitate project management and track project schedule, resources and overall progress. These tools offer a variety of features, from task and time management, up to integrated CRM (Customer Relationship Management) and ERP (Enterprise Resource Planning) modules. Currently, a large number of project management software is available, to assist project team during the entire project lifecycle. We present the main differences between open source and proprietary project management tools and how those could be important for SMEs, describing the key features and how those can assist the project manager and the development team. In this paper, we analyse four open-source project management tools: OpenProject, ProjectLibre, Redmine, LibrePlan and four proprietary tools: Bitrix24, JIRA, Microsoft Project and Asana.

ABSTRACT
The global sales market is currently led by devices with the Android operating system. In 2015, more than 1 billion smartphones were sold, of which 81.5% were operated by the Android platform. In 2017, it is estimated that 267.78 billion applications will be downloaded from Google Play. According to Qian, 90% of applications are vulnerable, despite the recommendations of rules and standards for the safe software development. This study presents a classification of vulnerabilities, indicating the vulnerability, the safety aspect defined by the Brazilian Association of Technical Standards (Associação Brasileira de Normas Técnicas - ABNT) norm NBR ISO/IEC 27002 which will be violated, which lines of code generate the vulnerability and what should be done to avoid it, and the threat agent used by each of them. This classification allows the identification of possible points of vulnerability, allowing the developer to correct the identified gaps

ABSTRACT
Elevation data is important for electric vehicle simulation. However, traffic simulators are often two-dimensional and do not offer the capability of modelling urban networks taking elevation into account. Specifically, SUMO - Simulation of Urban Mobility, a popular microscopic traffic simulator, relies on networks previously modelled with elevation data as to provide this information during simulations. This work tackles the problem of adding elevation data to urban network models - particularly for the case of the Porto urban network, in Portugal. With this goal in mind, a comparison between different altitude information retrieval approaches is made and a simple tool to annotate network models with altitude data is proposed. The work starts by describing the methodological approach followed during research and development, then describing and analysing its main findings. This description includes an in-depth explanation of the proposed tool. Lastly, this work reviews some related work to the subject.

ABSTRACT
Knowledge representation is a multidisciplinary subject that needs to apply theories, and techniques from logic, ontology, and computation, for this reason the Bodies of Knowledge (BOK), contain the relevant information for an area of knowledge, and it is necessary for the development of the science, and application in the professional, occupational profiles, and the possible incidence in the industry.
This paper showed an evaluation of professional, and occupational profiles based on standard Software Engineering Body of Knowledge (SWEBOK), and ontological model as tool in order to obtain the necessary information to establish the relationship in these contexts.
