Oracle Database

processing and output of information and data. Data bases are widely used in the world by different organisations, it is mostly used for its relational database as it uses key fields to link different data in tables which then are related to each other with easy access, this is mostly used to generate project plans and estimating future costs. Operational databases are used to store…

benefit of using a relational database is that it can help the efficiency of data storage by avoiding data duplication. It is very easy to change data and the format of it which can be added or removed easily. The data can only be stored once so no more than one record change is needed. Relational databases are used to work together by primary key and foreign key as this creates a link between more than one table. By this it can use the attributes and entities within the database which makes it…

The differences in SQL and Relational Algebra are not that many. In fact, they are pretty much the same thing. Both of them have commands that need to be evaluated in order to get a result or a new table. In the SQL, we have commands that need to be followed step by step. For example, the first thing we need to know if we need to join tables. After that, we need to know what columns or fields we are putting as a result, then what table or tables are those columns coming from, and last if there…

Task 9 COMPARE the usefulness of MySQL and QBE Query by example is a language used for relational databases like SQL. Its development was parallel to that of SQL’s as a database language. It was originally only able to retrieve data from a database, it was then later updated to do other operations like insert, update and delete data from a relational database. It is easier and more productive than SQL as you do not need to remember the finer details of the language as you can easily select…

Assignment Instructions: When a detection algorithm determines that a deadlock exists, the system must recover from the deadlock. The most common solution is to roll back one or more transactions to break the deadlock. List the three actions that need to be taken using figure 16.18 to discuss. (Silberschatz, Korth, & Sudarshan, 2001, p.618) A deadlock occurs when a sequence of transactions is waiting for access to data that is being held by a lock in another transaction in the same cycling…

Homework #1 1. The search term I used is “database security” because I am interested in it when I read through it. Moreover, I want to know more about the term “database”, and it found it means a controlled collection of data, and metadata, stored on computer. I also want to learn about ways to protect against threats that specifically target databases. Besides, I searched about “Relational Databases” because most databases are relational database, and they store their data in relation. 2. I…

transactions and business to fail. Databases need to handle all of these issues with ease. The data size will increase dramatically daily if a system like AutoXchange and Covisint runs successfully. The problem is that the relational database management system finds it challenging to handle huge data volumes. The solution to the problem is that the relational database management system needs to add more central processing units as well as to add more memory to the database management system in…

Step 9 monitors the database application systems and improves performance by making amendments to the design as appropriate. 16.2 What factors can be used to measure efficiency? There are a number of factors that we may use to measure efficiency: • Transaction throughput:…
