...PT2520 Database Concept Unit 7 Research Assignment 1. What are the advantages of a declarative language as opposed to a procedural language? ANSWER: The advantage of declarative programming languages is mainly two-fold. The programs are concise; this makes it easy even for non-programmers to obtain solutions. In the SQL example above, an analyst or business support person can get the desired information. Similarly, laypersons can write acceptable web pages with simple HTML and CSS commands. The second advantage of the declarative programming model is that repetitive imperative code that indicates how to solve things is provided in the computer system behind the scenes. Such code can be made highly efficient and can incorporate the best ideas from computing. It can take advantage of parallelism 2. What advantages might a procedural language have over a declarative language? ANSWER: Procedural programming is used for developing simple applications. The languages that use the procedural programming methodology include Pascal and C languages. Some of the benefits of the procedural programming methodology are: (1) Easy to read program code. (2) Easy maintainable program code as various procedures can be debugged in isolation. (3) Code is more flexible as you can change a specific procedure that gets implemented across the program. 3. Why do you think cross joins are allowed as a legitimate join? What uses can you see for joins? ANSWER: I think that a cross-join would...

...PT2520: Database Concepts ITT technical Institute Statement of Work * History: Wild Wood Apartments owns 20 different apartment complexes in Washington, Oregon, California, and Idaho. It is very important to keep track of the activities involved in running the apartment complexes, such as maintenance issues, which apartments are vacant and which are occupied, whether rent is being paid and the like. There is a vast amount of information involved in running a successful apartment complex. The current method of keeping track of this information is outdated and difficult to use. A new database would create a more accurate and user friendly method of keeping track of important business aspects. * Scope: The Wild Wood Apartments tracking database will track necessary business aspects involved in running the apartment complex. The database will track basic information such as apartment complex addresses, revenues, tenants, salaries paid to employees, total revenues and expenses as well as apartment occupancies and vacancies. It will track the leases on file, including when they begin and end, the lease contract number, names of the tenants, the amount of deposits paid and the monthly rent amounts. The database will also track monthly rent payments, including the amount that was paid, the date it was paid, whether or not the tenant was late making payment along with the tenants lease contract number and apartment number. Finally the database will track maintenance...

ANSI is also actively engaged in accreditation - assessing the competence of organizations determining conformance to standards. To enhance both the global competitiveness of U.S. business and the U.S. quality of life by promoting and facilitating voluntary consensus standards and conformity assessment systems, and safeguarding their integrity. ISO- International Organization for Standardization (ISO) is an independent, non-governmental international organization with a membership of 163 national standards bodies. Through its members, it brings together experts to share knowledge and develop voluntary, consensus-based, market relevant International Standards that support innovation and provide solutions to global challenges. Part II- The latest SQL standard was adopted in July 2003 and is often called SQL:2003. One part of the SQL standard, Part 14, SQL/XML (ISO/IEC 9075-14) was revised in 2006 and is often referenced as "SQL/XML:2006".

Database management system is reliable mean to organize date into a single location that can be searched and updated at any time. By adding all the information in one location or in this case a server you are storing the information for later use. You can than search any information you require and update it or even remove old items from the database. Today there are several different options or providers for a DBMS server. Among the top providers you have Oracle, MySQL, IBM DB, MS SQL Server. Oracle 12C Oracle 12C is a cloud base database management system. It supports the following operating systems (OS) Microsoft Windows, Linux, Oracle Solaris and some Unix. It is a web-based interface that stores all the procedures on the Oracle Management Repository. The most recent update was released on September 30, 2014. Some of the benefits of Oracle 12c are the following. Per oracle documentation “It provided a secure multitenant application by adding a layer of abstraction or containerization. It allows you to use the cloud providers for an easy and quick mean to allocate and manage the database across multiple systems and data centers without changing the application”. It also provides a disaster recovery, backup, patching, cloning and upgrading flexibility. Oracle is able to replace or move any information while you use either of the following RMAN, Data Guard...

...Jonathan Hindman PT2520 Chapter 4 10/18/13 Cardinality: Cardinality refers to the number of allowed instances of a relationship. In the usual cardinality of one to many, for instance, each record on the one side can have zero to any number of records on the many side. Cardinality can be more specific however. Each patron at a library can have only 20 items checked out at once. This has a cardinality of 0 to 20. Composite keys: In database design, a compound key is a key that consists of 2 or more attributes that uniquely identify an entity occurrence. Each attribute that makes up the compound key is a simple key in its own right. Crow’s feet notation: A type of notation for entity relationships in entity relation diagrams that depicts the many side of a relationship with a three-pronged end called a “crows foot.” This type of notation provides more information about the cardinality of a relationship than the arrow notation for relationships. Domain entities: Those database entities that relate directly to the business problem under consideration. Entity relation diagrams: A diagram that shows entities, their attributes, and the relationships among them. Linking entity: An entity used to resolve a many-to-many relationship into two one-to-many relationships. Logical entity: The design of a database without regard to the physical implementation of the database. Lookup entity: An entity used to store lookup values such as state names or zip codes. Maximum cardinality:...
