the database provides the ease of accessing and maintaining data easily. Advantages of RDBMS: 1. Prevents Data redundancy: In relational database management systems the tables with the specific data have relation among them that’s why the required data is taken from the previous tables which prevents the data redundancy. 2. Data security: In a relational database management system the data access is privileged which means that the database administrator has the authority of giving access of data to some particular users which makes the data secure.
SQL server database latest version is installed and its connection with the proposed visualization tools is tested. Appendix/ data dictionary is analyzed. Our aim for this project is tell stories using data visualizations. This will be accomplished by developing various types of visualization to appreciate and identify trends in data. 3 suggested visualizations, i.e.
DATABASE SECURITY: USING ENCRYPTION TECHNIQUE AND DESIGN IN DATABASE Mareena Sahoo Janvi Tanwani Prachi Soni email@example.com firstname.lastname@example.org email@example.com ABSTRACT: Database security is one of the most essential challenges in today’s world that the people are going through. In the research of traditional database, security is supposed to be authentic. The aim is to achieve security from the outside intruders and probably also against the user trying to access the personal information apart from their authorization. In this paper we discuss the problem of attaining security in an ambience where the database is not fully dependable,
Question 1 Differentiate between database management system and information retrieval system by focusing on their functionalities. (30 marks). Database management system Information retrieval system Main software in computer system Obtain resources to the information relevant Offer Data modelling Facility Restricted to classify of object Structured data format Unstructured data format Provide precise semantics Provide imprecise semantics Complete of query specification Incomplete of query specification Data dictionary system management Item normalization Data transformation and presentation Document database search Backup and recovery management Index database search Data store management Selective dissemination of information
SQL’s primary query language is Transact-SQL, an imple-mentation of the ANSI/ISO standard Structured Query Language (SQL) used by both Microsoft and Sybase. Microsoft SQL Server supports isolated, durable trans-actions, atomic and consistent,. SQL in-cludes support for database mirroring and clustering. An SQL server cluster is a collec-tion of identically configured servers, which help distribute the workload among multiple servers. SQL server also supports data parti-tioning for distributed databases, in addition to database mirroring which allows the crea-tion of mirrors of database contents, with transaction logs, on another instance of SQL Server, based on certain predefined
Java has been used in many applications such as Androids apps and the most widely used websites. It is important to recall that most of the programmers learn Java during their educational journey to learn programming. Most of programmers end up by using Java because it has a significant advantages compared to other programming languages, which make it the best choice for any programming
Some of Boolean model disadvantages include the fact that Users find it difficult to construct effective Boolean queries for several reasons such as when Users are using the natural language terms AND, OR or NOT that have a different meaning when used in a query which can cause them to make errors when they form a Boolean query based on their real linguistic meaning (Croft, 1986). Different methods can be used to improve scoring and ranking in search systems. These methods can include both safe where only the exact match of the search query should appear in the search results and un-safe ranking where a percentage of wrong or unrelated search results can appear as part of the search results. Some these techniques include index elimination where for a multi-term query q, the only consideration is for documents containing at least one of the query terms. This could entail only considering documents containing terms whose idf exceeds a pre-set threshold.
This is so, because the traffic to and from your website cannot be seen as drawing too much of the bandwidth. This could potentially slow down other sites on the server. This is why many hosts will give unlimited bandwidth and yet control the traffic speed, so as to equitably share the resources of the server. -Support The importance of support cannot be over emphasized. It will serve as a guide as you grow more and more accustomed to the world of shared hosting.
Cloud computing has many potential advantages and many applications enterprise in nature and data is transferred to public or hybrid cloud. The market size of the cloud computing shared is very vast as is expected. The data reachability model proposed for online data security elucidates potential linkages between data typically exposed on
