Relational database management system

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…

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…

Discuss the advantages of a database management approach to the file processing approach? Give examples to illustrate your answer. According to our text, database management is the process of storing data. In the early days of computers, they would use data resource management to store information in a specific location. This process was very inflexible and extremely costly. Instead, we use database management today. This process allows us to consolidate the data, and integrate it into many…

Storage Systems for Big Data Internet age comes with the vast amount of data that requires efficient storage and processing capabilities. To alleviate this issue, we discuss data storage systems which are tailored to store and process big data effectively. While general-purpose RDBMSs are still viable option in handling and analyzing structural data, they suffer from a variety of problems including performance and scalability issues when it comes to big data. To increase the performance of DBMS…

A database object in a relational database is a data structure used to either store or reference data. The most common object that people interact with is the table. Other objects are indexes, stored procedures, sequences, views and many more. When a database object is created, a new object type cannot be created because all the various object types created are restricted by the very nature, or source code, of the relational database model being used, such as Oracle, SQL Server or Access. What…

of not only NOSQL but also its opposing and conjoining systems, and their pro’s and con’s. To really understand these comparisons, you need to have an Idea of what JavaScript and JSON are in addition to the LAMP and MEAN stacks. The term LAMP referrers to (Linux, Apache, MySQL (SQL), PHP). The LAMP stack is a common stack of open source and free languages. This stack uses Linux as the operating system Apache as the server, MQSQL as the Database and PHP…
