Unit 5 database discussion assignment Assuming we are joining on columns with no duplicates, which is a very common case: An inner join of X and Y gives the result of y intersect z, i.e. the inner part of y intersection. An outer join of y and z gives the results of A union z, i.e. the outer parts of y Venn diagram union. Simple Examples if we have two tables, which contains a single column each, with the data as follows: y z - - 1 3 2 4 3 5 4 6 in the above given data lists table

Differentiate between database management system and information retrieval system by focusing on their functionalities. A database management system in the main software tool of the database management approach because it controls the creation, maintenance, and use of the database of an organization and its users. The three major functions of a database management system are first to create new database and database application. Second to maintain the quality of the data in an organized database

Project Deliverable 3: Database and Programming Design A quality database design makes the flow of data seamless. The database schema is the foundation of the relational database. The schema defines the tables, fields, relationships, views, indexes, and other elements. Envisioning the primary business function should facilitate creating the schema and how that information should flow throughout all areas of the firm. ("Strayer, iCampus," n.d., p. 1). Database Design Basics The database itself

search can get complicated with the approach if the tags are not matched properly but the table can be used more effectively as we need to put entries for a branch instruction in a particular order. Set associative mapping is made up of direct and full associated mapping. The branch address is mapped to multiple entries of the table while inside those set of entries, search is made fully associative. When several processes are using same processor, then running one process, suspending it, then storing

Advantages of a Relational Database The relational database provides a number of advantages over previous models, such as the following. • Built-in multilevel integrity: Data integrity is built into the model at the field level to ensure the accuracy of the data; at the table level to ensure that records are not duplicated and to detect missing primary key values; at the relationship level to ensure that the relationship between a pair of tables is valid; and at the business level to ensure that

Annotated Bibliography The topic I chose is the legalization of marijuana. My research was enjoyable because I love reading on a topic that I fully support and agree with. The four sources I found are very persuading and contain strong points. I used the web for research but as I found sources, I made sure they were credible sources since this is such a debatable issue. Jacques, Renee. "This Is Why Marijuana Should Be Legal Everywhere."

Advantages Reduction of of data redundancy Data redundancy could be defined as keeping the same piece of data in two separate places within a database or data storage technology. Traditional file-based systems stores the same information in more than one file through which space is wasted unnecessarily. But the DBMS ensure that multiple copies of the same data are not stored by integrating the files to eliminate the redundancy. Sometimes, it is necessary to duplicate key data items to model relationships

There are two main types of network-based storage, storage-area networks (SAN) and network-attached storage (NAS). Choosing between a SAN and a NAS system depends on user’s needs. In fact, each technology certainly has its own advantages as well as disadvantages. A storage-area network (SAN) is a “dedicated high-speed network used to connect and manage shared storage devices.” A SAN network makes it easier for all serves to access unlimited number of storage devices through a LAN or WAN without using

I began using computers when I attended South Puget Sounds Community College (SPCC) in 1980. I completed and passed Data Entry classes. Utilizing the skills I learned, I went to work for the State of Washington Labor and Industries and Department of Revenue as a Data Entry Operator, from 1981-1983. While working for US Intelco Network, Inc. as an Accounting Clerk in 1988, I again attended SPCC and completed Lotus 123 - a discontinued spreadsheet program that has many similarities to EXCEL. After
