  • Embedded Database for Remote Process Management System
    Embedded Database for Remote Process Management System {tag} {/tag} IJCA Proceedings on International Conference on Emerging Frontiers in Technology for Rural Area (EFITRA-2012) © 2012 by IJCA Journal EFITRA - Number 4 Year of Publication: 2012 Authors: Kalyani N. Satone Madhuri M . Pal {bibtex}efitra1030.bib{/bibtex} Abstract This paper investigates embedded databases for the MicroBaseJ project. The paper aims at the development of an integrated database and a user interface for a typical 3G mobile phone with Java MIDP2 capability. One of the key objectives is to target a generic solution. A number of commercial sectors could benefit from this solution such as horticulture, building management, pollution/water management, industry etc. Four embedded databases based on J2ME have been investigated. Two of the four have been evaluated and analyzed. The size of processed data is limited to 20000 records when using the wireless toolkit simulator and 11000 records when using a mobile phone. 1 / 3 Embedded Database for Remote Process Management System Refer ences - Mobile and World, "Subscriber statistics end Q1 2007," 2007. - S.

  • Java Database Connectivity (JDBC) J2EE Application Model
    Java DataBase Connectivity (JDBC) J2EE application model J2EE is a multitiered distributed application model client machines the J2EE server machine the database or legacy machines at the back end JDBC API JDBC is an interface which allows Java code to execute SQL statements inside relational databases Java JDBC driver program connectivity for Oracle data processing utilities driver for MySQL jdbc-odbc ODBC bridge driver The JDBC-ODBC Bridge ODBC (Open Database Connectivity) is a Microsoft standard from the mid 1990’s. It is an API that allows C/C++ programs to execute SQL inside databases ODBC is supported by many products. The JDBC-ODBC Bridge (Contd.) The JDBC-ODBC bridge allows Java code to use the C/C++ interface of ODBC it means that JDBC can access many different database products The layers of translation (Java --> C --> SQL) can slow down execution. The JDBC-ODBC Bridge (Contd.) The JDBC-ODBC bridge comes free with the J2SE: called sun.jdbc.odbc.JdbcOdbcDriver The ODBC driver for Microsoft Access comes with MS Office so it is easy to connect Java and Access JDBC Pseudo Code All JDBC programs do the following: Step 1) load the JDBC driver Step 2) Specify the name and location of the database being used Step 3) Connect to the database with a Connection object Step 4) Execute a SQL query using a Statement object Step 5) Get the results in a ResultSet object Step 6) Finish by closing the ResultSet, Statement and Connection objects JDBC API in J2SE Set up a database server (Oracle , MySQL, pointbase) Get a JDBC driver

ETH Library Investigating a Constraint-Based Approach to Data Quality in Information Systems Master Thesis Oliver Probst <[email protected]> Prof. Dr. Moira C. Norrie David Weber Global Information Systems Group Institute of Information Systems Department of Computer Science 8th October 2013 Copyright © 2013 Global Information Systems Group. ABSTRACT Constraints are tightly coupled with data validation and data quality. The author investigates in this master thesis to what extent constraints can be used to build a data quality manage- ment framework that can be used by an application developer to control the data quality of an information system. The conceptual background regarding the definition of data qual- ity and its multidimensional concept followed by a constraint type overview is presented in detail. Moreover, the results of a broad research for existing concepts and technical solu- tions regarding constraint definition and data validation with a strong focus on the JavaTM programming language environment are explained. Based on these insights, we introduce a data quality management framework implementation based on the JavaTM Specification Request (JSR) 349 (Bean Validation 1.1) using a single constraint model which avoids in- consistencies and redundancy within the constraint specification and validation process. This data quality management framework contains advanced constraints like an association con- straint which restricts the cardinalities between entities in a dynamic way and the concept of temporal constrains which allows that a constraint must only hold at a certain point in time.
