Advantages of MySQL over Oracle:
MySQL is a fast, reliable, robust and open source database system that has a large number of features too offer. Administration and security are effective and are easily setup. MySQL would be recommended for more of a medium sized business where processing data to and from the database wasn’t so enormous, it is more suited and aimed towards websites.
MySQL does lack some features that oracle offer but the development team seem to be added new features to MySQL on a regular bases. MySQL is more suited for a website or smaller companies that don’t require massive amounts of database usage.
Advantages of Oracle over MySQL:
Oracle is a much larger database software, it can handle much more database requests and manage more transactions than MySQL. MySQL take resources from the system to processes the requests which can put a large load on the system. However oracle has a built in memory management feature that spreads the load across multiple threads making it much faster and less effective on the system running it.
Oracle is mainly used by larger companies, this is due to the licensing costs or due to the amount of data they are processing. MySQL uses the memory of the system to process so you will see a decrease in the system over time or after a couple of thousands of rows of data, Oracle is less effective on the system and is mainly used by companies that are processing large amounts of data such a data warehouse. Oracle’s backup feature is much faster and better than the MySQL, It saves a backup in seconds/minutes whereas MySQL can take forever.

...contains information about all the updates to the database. A log file usually contains Transaction reports and checkpoint records.
Write-Ahead Logging: This is when the transaction is entered into the system log before it is even written to the database.
Steal /No Steal: If a cached page is updated by a transaction cannot be written to the disk before the transaction commits, its known as a No-Steal Approach. If writing before the transaction commits it’s known as a steal approach.
Force / No-Force: If all updates made by a transaction are immediately written to the database by a commit it’s known as a ‘Force’. If it’s not immediately written it’s a ‘no-force’.
Checkpoints: A checkpoint is a synchronisation between the database and the system log file. A checkpoint record is logged at intervals when the system writes out to disk all buffers that have been modified.
Each transaction is stored in a log file that will be useful, in conjunction with the error files, in case one of the processes fails validation to go back and find out which process was to determine the cause of the
In the past number of years data has grown exponentially. This growth in data has created problems that and a race to better monitor, monetize, and organize it. Oracle is in the forefront of helping companies from different industries better handle this growing concern with data. Oracle provides analytical platforms and an architectural platform to provide solutions to companies. Furthermore, Oracle has provided software such as Oracle Business Intelligence Suite and Oracle Exalytics that have been instrumental in organizing and analyzing the phenomenon known as Big Data.

In 1979, RSI developed and distributed its first commercial SQL database V2, there was no version 1. In 1982, RSI changed its name to Oracle Systems Corporation, which later changed again to Oracle Corporation. They reasoning behind this was that they thought by naming the company after the product it would help the company obtain more recognition.

Backup copies are processes that are used to save information. It is to say, a user wants to save all the information or part of the information available on the PC up to this moment; will make a backup copy in such a way that it will save the information in some technologically available storage, the urgent care clinic, the Systems area has two of the Servers as Backups administrator (Allen 2004)[2]; for later if a loss occurs in the computer equipment of one of the users and information is lost, from the Systems area the process of restoring the information to the date of the last backup made by the end user can be performed. In order for the process to be functional, users must periodically complete the process according to the indications given by the Systems
Settle the actions to be performed on the database, such as transformations, validations, reports and tasks.
This process enables the software to reproduce the same execution codes as when the date occurred. An example similar to this concept would be playing a video game and saving the progress to access it on a different day. When a video game is saved, the checkpoint provides a temporal illusion to the computer. This links back to the theory about differences in time perceptions, computers are no exception to that concept. Time travel through computer programming is basically tricking the computer to accept the message the programmers want to convey in the form of code. Although this is not a physical means of time travel, programmers can send encrypted codes to a random time frame of their desire and as long as the files find a medium to project the information, recipients on the other end can view the information the programmers want to present (Ortego, 2005, pg. 8). This theory is known as time travel through parallel

Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
A database is a structured collection of data. Data refers to the characteristics of people, things, and events. Oracle stores each data item in its own field. For example, a person's first name, date of birth, and their postal code are each stored in separate fields. The name of a field usually reflects...
The DBMS has a function that can be differentiate from the information retrieval system. The DBMS have the ability to store, update and retrieve the data. This is the main function of the DBMS because the database can be used if there is any record is being stored into the database. The record need to be retrieve first, then it can be change by the database administrator as it will be the record has been updated. The DBMS will protect the structure of the data structure.
In this report I will discuss briefly how transaction management can be used within the database I will also discuss how concurrency and recovery can be used within databases I intend to use the database platforms provided by Microsoft and Oracle.
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
