Database marketing

We’ve used a lot of devices and storages so far in our life, but one thing that might be weird to people is the RAID. RAID stand for redundant array of independent disks and is a place for people to store their information. It is stored on CDs, instead of the normal flash drives and hard drives. RAIDS are different from the normal CDs, because they have to divide the data and spread the blocks into several megabytes for RAID to work. This is to make RAID efficient and fast. There are lots of…

business databases and files were stored. Throughout the firm, multiple databases were isolated and duplicated among departments. This had caused issues, such as their subscribers receiving unnecessary marketing material, and not being able to keep the databases secure. In order for them to solve this issue was to implement and store all company data into a data warehouse using SAP NetWeaver, as well as educate their own employees on the new system to prevent further inconsistent databases. By…

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…

Being and active duty member of the United States Coast Guard, I conduct multi-mission maritime services throughout the globe. I save lives, provide a safe transportation system, protect the environment, enforce laws and protect our national security. Over the years, these services have caused a demand for information system to revolutionize. These advances are needed to analyze and interpret data to coordinate responses to emergencies, track vital information and train personnel. One…

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…

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:…

responsibilities include physical design, installs, security, backups, and requirements of the database. 7. The trade-offs for concurrency controls are: a. If it’s too strict it can lead to locking the entire database. b. Other measures have low level of concurrency control. 8. Atomic transaction ensures that all the actions on the database are done or none of them are done at all. If none of them are done then the database remains unchanged. It’s important because if ensures that important…
