(i) End-user Support: From the diagram above you will realize that the DBA defines and enforces the procedures and standards and in doing this the end users will follow the systems set down to work with the database application. In order to achieve this there are some tactics I will adapt to ensure that end-users adhere to procedures and standards and also they are okay with everything. These are. a.

1. While users were updating the Premiere Products database, one of the transactions was interrupted. You need to explain to management what steps the DBMS will take to correct the database. Using the sample log in Figure 7-1 1, list and describe the updates that the DBMS will roll back if transaction 2 is interrupted at 8:10. In transaction 2, the DBMS started it at 8:01, added an Orders table record at 8:02, and added an Order Line table record at8:05 and added an Order Line table record at 8:09

explain what is Hadoop and what is Big Data. We will define some Hadoop-related open source projects and give some examples of Hadoop in action. Imagine this scenario: You have 1GB of data that you need to process. The data is stored in a relational database on your desktop computer and this desktop computer has no problem handling this load. Then your company starts growing very quickly, and that data grows to 10GB. And then 100GB. And you start to reach the limits of your current desktop computer.

Database Design Larry Cohen DBM 380 James Cervi November 10, 2014 Database Design Database Systems A database is a structured group of data that is warehoused in a system. In order for a database to be functional it must be accessible and store large amounts of data. In order for databases to be reliable, in the event of a hardware failure, it must be easily recoverable. Also, the database must be flexible. Meaning, if there is something new that needs to be implemented, the database must

Database Management System OLAP (On-Line Analytical Processing) The main reason of using OLAP to answer queries is speed. Relational databases store entities in discrete tables if they have been properly normalized. This structure is good for operational databases but for complex multi-table queries is comparatively slow. A better model for querying but worse for operational use is the dimensional database. OLAP take a snapshot of a relational database and restructures it into dimensional data
