...Relational Database Management Systems Object Oriented Databases The database world is in a constant change! New techniques for concurrency control, cloud platforms, object databases, and service platforms are all being changed and talked about in the industrial and academic world. OODB has been around since the seventies when object oriented programming was first being developed. That being said; companies have only started using object oriented databases in the last ten to fifteen years. In the early 1980’s a Microelectronics and Computer Technology Corporation employee begins ORION. ORION is able to handle schema evolution and complex object looking. During the late 1980’s the first wave of commercial OODMS hits. In this time period we get the beginning of Graphael, which later becomes Matisse. Designed to benefit all perspectives of object oriented databases, Matisse combines native support for SQL, Object and XML all in a single database. Next we get the GemStone Systems, the earliest OODB that supports object identity, inheritance and encapsulation. On into the late 1980’s France starts the development of O2. It is C++ compatible and supports multiple inheritances. Later on Vbase was produced, which use the language COP. COP is changed into a C++ based system that supports encapsulation, ability to construct complex objects, and inheritance. (“Short History”, 2005) Once we get into the 1990’s the first standard is released, ODMG 1.0. During this time frame a common query...

...1. What is a transaction? What are its properties? Why are transactions important units of operation in a DBMS? As defines by the Elmasri and Navathe, Transaction is a sequence of operations that performs logical unit of operations on a database which include one or more operations as insert, delete, update and modification, Transaction is a executing program, the boundaries of a transaction is define as the explicit begin of transaction and end of transaction. Read-only transaction performs only retrieve data from the database and the Read- write operation includes both retrieving and updating transactions. (Elmasri and Navathe 2010 p.745) The properties of a transaction is define as ACID properties as below, Atomicity, Consistency, Isolation and Durability Transaction is the executing program that executes the operations on the database as read(x), write (x) ,so the transactions plays a vital role among database operations. 2. Draw a state diagram and discuss the typical states that a transaction goes through during execution. Figure1. State Diagram of a Transaction Source: Author Begin transaction: This indicates the beginning of a transaction Active phase: in this phase the running of the database operations or write sql queries for perform the tasks is done Partially committed: After performs the needed operations the transaction indicates end state and come to the phase partially committed and store in the buffer but not permanently. Committed: If the transaction was...

...1. Data is raw facts that have not been processed to reveal their meaning to the end user. Field is a character or group of characters that has a specific meaning and is also used to define and store data. Record is a logically connected set of one or more fields that describes a person, place, or thing. File is a collection of related records. 3. Date independence exists when you can change the data storage characteristics without affecting the program’s ability to access the data. Data independence lacks in file systems because any program that accesses a file system's file must tell the computer not only what to do, but how to do it. Each program must contain lines that specify the opening of a specific type of file, its record specification, and its field definitions. Data dependence makes the file system very difficult from the point of view of a programmer and database manager. 5. Structural independence is exists when you can change the file structure without affecting the application's ability to access the data. Structural independence is important because it would be very difficult to make changes to an existing file structure, resulting in going through a number of steps and producing errors. 7. The role of a DBMS is to serve as the intermediary between the user and the database. The DBMS receives all application requests and translates them into complex operations required to fulfill those request. The advantages of a DBMS are the following: *...

...Art Museum Database What is Needed and What Can Go Wrong Craig Hill University of Phoenix Analysis- A database needed to accomidate an art museum would be vary simple an very complicated at the same time. The database would need to have the names of the artists, name of the art and where it is located. Along with the entities stated above, there would also be the details that are unseen in the database. When the art was purchased or donated, the estimated value, the year it was painted, what kind of media was used, ect. In order to have a full database of information you would need the afformentioned data, and that is where you come into trouble and constraints. Problems- The amount of data that could be entered would be endless when it comes to art, so when the database is being created it needs to be taken into account that memory limits are in place. So choosing what query criteria should be used is vital. Obviously you want to be able to search for art by name, easy enough. What if someone at the museum wanted some deeper information such as what art is the oldest, what is the most expensive art and what art was done with a specific type of media. You would need to think critically so that these questions could actually be answered upon request. There are plenty of problems that can stem from database creation. 1. “Poor design/planning 2. Ignoring normalization 3. Poor naming standards 4. Lack of documentation 5. One table to hold...

...RUNNING HEAD: Nursing Profession Nursing Profession Nursing Profession A profession is defined as an occupation requiring special education (especially in the liberal arts or sciences). There are many characteristics that make up a profession, for example professionals are considered experts having a higher degree of knowledge and autonomous. Professionals are governed by a code of ethics such as value, quality of service, honor and integrity. A hallmark that is also acknowledged is accountability. There is typically a system in place to test out the competence of professionals. The nursing profession as a whole, through its professional and regulatory organizations, promotes advancement of nursing practice, identifies standard of practice and promotes professional development (Bassendowski & Petrucka 2009). Historically, nursing has been understood as a calling or a vocation, but modern, secular nursing has essentially understood itself as a profession and, more recently, as a practice (Liaschenko, & Peter, 2004). Although it is considered to be a profession by those in nursing, it has not been categorized as a true occupation in the sociology of professions’ literature, one of the key issues is related to the formal knowledge of nursing and the power associated with it (Yam, 2004). It has been argued that nursing does meet the professional criteria and it is a clear it does not now and never did have...

...“ Spanner : Google’s Globally – Distributed Database “ Spanner is a NewSQL created by google. It is a distributed relational database that can distribute and store data in google’s big table storage system in multiple data centers. Spanner is Google’s scalable, multi-version, globally distributed, and synchronously-replicated database. It is the first system to distribute data at global scale and support externally-consistent distributed transactions. Spanner provides the scalability that enables you to store a few trillion database rows in millions of nodes distributed to hundreds of data centers. When you read data, spanner connects you to data center that is geographically closest and similarly when we write the data, it distributes and stores it to multiple data centers. If in case the data center we try to access has a failure we can read the data from another data center that has a replica of the data. Replication is used for global availability and geographic locality clients automatically failover between replicas. Applications can use spanner for high availability even in the face of wide-area natural disasters, by replicating their data within or even across continents. Spanner’s main focus is managing cross-datacenter. Many applications at google have chosen to use Megastore because of its data model and support for synchronous replication despite poor throughput. Applications can specify con-straints to control which datacenters contain which data, how...

...1. What is different between TRUNCATE and DELETE? The Delete command will log the data changes in the log file where as the truncate will simply remove the data without it. Hence Data removed by Delete command can be rolled back but not the data removed by TRUNCATE. Truncate is a DDL statement whereas DELETE is a DML statement. 2. What are ORACLE PRECOMPILERS? A precompiler is a tool that allows programmers to embed SQL statements in high-level source programs like C, C++, COBOL, etc. The precompiler accepts the source program as input, translates the embedded SQL statements into standard Oracle runtime library calls, and generates a modified source program that one can compile, link, and execute in the usual way. Examples are the Pro*C Precompiler for C, Pro*Cobol for Cobol, SQLJ for Java etc. 3. What is difference between procedure and function. A function always returns a value, while a procedure does not. When you call a function you must always assign its value to a variable. 4. What are things you do to reduce patch timing ? You can take advantage of following - # Merging patches via admrgpch # Use various adpatch options like nocompiledb or nocompilejsp # Use defaults file # Staged APPL_TOP during upgrades # Increase batch size (Might result into negative ) 5. What is the purpose of a cluster? A cluster provides an optional method of storing table data. A cluster is comprised of a group of tables that share the same data blocks, which...
