With the adoption of UML 2.0, the new enhancements allow this version to describe many of the elements found in today's software technology as well as Model Driven Architecture and Service-Oriented Architecture. Many existing software applications involve complex application layer implemented in object-oriented programming languages and at the same time use relational database systems as the back-end data store. Modeling the whole system in a consistent manner will help developers and end users better understand the application. The Unified Modeling Language (UML) is a standard language for modeling software and database systems. Data...

...(Database Design Using Entity-Relationship Diagrams) Checkpoint 1.1 1. Briefly describe the steps of the software engineering life-cycle process. a) Requirements – looking out what the user(client) needs and the problems b) Specification – make an analysis of the requirements. Find out the specifics needs c) Design – after you gather enough information, you design to meet the specification d) Developed – you star to write the software e) Tested – software is turned over to the user to be used in the application f) Maintenance – involves correcting hidden software faults as well as improving the functionality of the software. Checkpoint 1.3 1. What are functional dependencies? Give examples. A functional dependency is a relationship of one attribute or field in a record to another. For example, Social Security Number defines a name. This means that if I have a database with SSNs and names, and if I know someone’s SSN, then I can find their name. Another example would be the Employee’s number, if I know the EmpNo, and then I know the name. 2. What does the augmentative rule state? Give examples. Like the book explain, if. It means that you can add more information to the LHS of an FD and still have the FD be true. An example: If X is customer ID and Y is customer name and Z is birth date, then means that if you are given both a customer ID and a birth date, then it is possible to derive customer name and birth date from that. 3...

...YFOSBAPP Database A database is information organized in such a way that a computer program can quickly select pieces of data. You can think of it as an electronic filing system. A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views and other objects. Data Integration Data integration involves combining data residing in different sources and providing users with a unified view of these data. This process becomes significant in a variety of situations, which include both commercial (when two similar companies need to merge their databases) and scientific (combining research results from different bioinformatics repositories, for example) domains. Data integration appears with increasing frequency as the volume and the need to share existing data explodes. It has become the focus of extensive theoretical work, and numerous open problems remain Existing DBMSs provide various functions that allow management of a database and its data which can be classified into four main functional groups: Data definition – Creation, modification and removal of definitions that define the organization of the data. Update – Insertion, modification, and deletion of the actual data. Retrieval – Providing information in a form directly usable or for further processing by other applications. The retrieved data may be made available in a form basically the same as it is stored in the database or in a new...

...ABSTRACT This term paper discusses the security exposures of a server that occur due to a SQL injection flaw in a web application that communicate with a database. Over ten years have passed since a famous hacker coined the term “SQL injection” and it is still considered one of the major application threats. A lot has been said on this vulnerability, but not all of the aspects and implications have been uncovered, yet. This paper aim is to collate some of the existing knowledge, introduce new techniques and demonstrate how to get complete control over the database management system's underlying operating system, file system and internal network through SQL injection vulnerability in over-looked and theoretically not exploitable scenarios. This paper also discuss about the prevention from the SQL Injection, not only in ORACLE but also in PHP, C#, JAVA and other languages.

...Federated Searching: A New Era “Only librarians like to search; everyone else likes to find” (Tennant, 2003). While most librarians teach research strategies including: Boolean logic, accessing carefully chosen databases, and indexing; students are often discouraged and frustrated using these techniques. Most students simply want to Google their requests. For many students a simple keyword search is a convenient, simple process for locating information. Federated searching is providing options that may strike a happy medium for students and librarians alike by providing a keyword option to access the library’s databases. Federated searching is software or a service that allows multiple sources to be searched simultaneously. A library is required to purchase software and/or a service agreement from a vendor that provides access to information in the databases and on the Web. Using a search protocol, like Z39.50, the engine scans various databases, the Web, and library catalogs concurrently and provides an organized result for the searcher’s query. Metasearches are performed across both bibliographic and full-text databases. One major advantage of a federated search is that the query does not have to be repeated with various databases. When federated searching works well, it reduces the amount of time students spend locating data and encourages them to search for more information. “The goal of many federated search tools is to make the interface as simple and streamlined...

...Week 1: Database Paper Carmen Lozano DBM/381 John Italiano April16, 2013 When it comes to the health care database systems is a special data processing system, or part of a data processing system, which aids in the storage, manipulation, reporting, management, and control of data. When it comes to a database management system is a collection of software packages designed to store, access and manage databases. Databases are used across the health care industry to able to store patient’s files because the databases are used to store data over a long period of time. In addition it helps organizations have file access to patients file and being able to check the status or enter patients information and sure it with different organizations. When it comes to health care database systems there are four different structural types of database management systems and they are hierarchical databases, network databases, relational databases, and object-oriented databases. Hierarchical database is commonly used on the mainframe computers; this is also the oldest method being used by organizing and storing data, by organizations. This structure follows the pyramid fashion. This means that related fields are grouped together which includes higher-level records and lower-level records. When using this structure there are advantages and disadvantages that go along with this method. The advantages are files can be accessed and...
