...International Journal of Scientific & Engineering Research Volume 3, Issue 3, March -2012 ISSN 2229-5518 1 A Distributed Transaction Model for a Multidatabase Management System Omar Baakeel and Abdulaziz Alrashidi Abstract— This paper examines the distributed transaction issues that are present in multi-database management systems (DBMSs) and how the distributed transaction in database technology differs from other distributed processing systems. Some common issues that arise with the distribution of transactions over a multi-DBMS while dealing with concurrency control and recovery are highlighted, such as site failure, network failure, and time failure. This study proposes an exceptional distributed transaction model for processing transaction queries in multi-DBMS based on the idea that a complete database can be constructed at any stage. Index Terms— Database management system (DBMS), distributed transaction, transaction management, transaction network —————————— —————————— 1 INTRODUCTION ENERALLY, a distributed transaction is defined as a transaction that updates data on two or more networked computer systems. Different conceptual structures for processing transaction elements are required to meet certain needs of applications that must update distributed data in terms of peer to peer connection. Developing a transaction model is difficult because most of these techniques are customized for a single transaction point, and many types of failures, such as client failure...

...A database management system (DBMS) “creates, reads, updates, and deletes data in a database while controlling access and security” (Baltzan, 2015, p.92). The database management system that I have decided to write about is MySQL. SQL stands for structured query language which “asks users to write lines of code to answer questions against a database” (Baltzan, 2015, p.92). The company that makes and distributes the system is Oracle Corporation. Oracle Corporation is a worldwide computer technology corporation that was founded on July 16, 1977 in Santa Clara, California by Larry Ellison, Bob Miner, and Ed Oates. The headquarters are located in Redwood City, California and focuses on increasing and selling computer hardware systems and enterprise software products but mostly its own brands of database management systems. Oracle also builds tools for database development and systems of middle-tier software, enterprise resource planning (ERP) software, customer relationship management (CRM) software, and supply chain management (SCM) software. In this article “DBA and Developer Guide to MySQL 5.6”, talks about the new development of MySQL on how it is much better and that it has improved and just explaining more about its improvement. It has better performance and scalability, better application availability with online DDL/Schema, and better developer agility with NoSQL Access with Memcached API to InnoDB. It has improved in replication for high performance, self-healing,...

...-1 1. List four significant differences between a file-processing system and a DBMS. * A database management system coordinates both the physical and the logical access to the data, whereas a file-processing system coordinates only the physical access. * A database management system reduces the amount of data duplication by ensuring that a physical piece of data is available to all programs authorized to have access to it, whereas data written by one program in a file-processing system may not be readable by another program. * A database management system is designed to allow flexible access to data, whereas a file-processing system is designed to allow predetermined access to data. * A database management system is designed to coordinate multiple users accessing the same data at the same time. A file-processing system is usually designed to allow one or more programs to access different data files at the same time. 2. Explain the concept of physical data independence, and its importance in database systems. The ability to modify a schema definition in one level without affecting a schema definition in the next higher level is called Data Independence. The ability to modify the physical schema without causing application programs to be rewritten or without changing the logical schema is called physical data independence. Importance of data independence in database systems: * Improve performance * Change in data structure do not require...

...Question 1 1.1 A database management system (DBMS) is a software package designed to define, manipulate, retrieve and manage data in a database. A DBMS generally manipulates the data itself, the data format, field names, record structure and file structure. It also defines rules to validate and manipulate this data. A DBMS relieves users of framing programs for data maintenance. Fourth-generation query languages, such as SQL, are used along with the DBMS package to interact with a database. Examples of Database Applications The following are examples of database applications: • Computerized library systems • Automated teller machines • Flight reservation systems • Computerized parts inventory systems 1.2 Advantage Disadvantage Controlling...

... number: n08745871 Research project title: Designing a database structure system for management hospital information. Field of research: Information system; database structure; hospital information Section B: Aims This project is going to indicate a new database structure model used to manage information in hospital management with respect to utilizing information and communication technology. It will enhance hospital to retrieve, process and achieve all the information in specific health facilities in a security domain. In fact, the database structure is not really considered as an important aspect in patient informational management in hospital. From the synthesis of the results of current hospital, the management of information within the hospital will include: management of patient information, medical information, laboratory data, diagnostic results, treatments, financial, pharmaceutical, medical equipment and general operations of the hospital. There are numbers of documentation in the database, the problem is illustrated that a hospital database management does not have the same synchronization in all fields. Consequently, it is quite difficult for any information activity in the process. To help resolve this situation, our project will develop a new database structure model that can fit most of the hospitals at all levels and to manage large ...

...The SCDS Group Global Article - Bitcoins Bitcoin is a digital currency invented in 2008 by Satoshi Nakamoto, a pseudonym for a person or group who, apart from a 2008 paper introducing Bitcoin, have remained anonymous and absent (Carmody, 2013). The currency has been gaining wider acceptance across the globe with 30% of Bitcoin transactions going through China’s BTC exchange (Tseng, 2013). There are estimated to be an average of 50,000 to 70,000 Bitcoin transactions daily to purchase goods such as video games, books, computer servers, and more (Bitcoin is an innovative payment network and a new kind of money, 2013). The introduction of a decentralized digital currency has many potential positive and negative consequences to the global economy and the societies that participate in global economy. One positive consequence of using Bitcoin is that it allows access to participate in the global economy without the need for a bank account and its associated banking infrastructure. Anyone with internet access via a computer or mobile device is able to set up a Bitcoin account and begin exchanging the virtual currency. This directly benefits third world countries where exchange of currencies and banking is not easily accessible. Another positive resulting from the introduction of Bitcoin is the potential savings that can result from using the currency when transacting between two parties that do not share a common local currency. The biggest potential for Bitcoin worldwide is probably...

...The efficient database management systems have been very crucial assets for management of a huge amount of data, especially for effective and efficient retrieval of particular information from a large collection whenever needed. The wide spread of database management systems has also influenced the recent massive gathering of all sorts of information. Today, we have far more information than we can handle, from business transactions and scientific data, to satellite pictures, text reports and military intelligence. Information retrieval is not enough anymore for decision-making. Faced with huge collections of data, we have now created new needs to help us make better managerial choices. As we make a shift from collecting to connecting data, businesses are searching for relationships between data sets to reveal valuable new insight. How do we then sort this huge chunk of data, how do...
