Migration of Database
Migration of Databases – An XML Approach

XML Database Migration is a project of migrating the existing databases into XML format. Conversion of databases to XML file format, the databases like Ms-Access, Oracle and MS-SQL, MySQL connects in the network or the oracle in the personal computer can be connected for the generation of XML code. Let us consider, user runs a firm with three companies with different database’s respectively. User planned to mingle the entire database’s of the firm in to a single database. The user wants to migrate the entire database in to a single database. Migration of a database to another database is a huge process and a complex one. In such case our project can be used as we are converting the entire database into a XML file and then it is to a single database. By doing so, the conversion is been made easier and the native database also will remain unchanged. Only the authorized person is allowed to access the databases. The user is been prompted for username and password and then the user can be allowed to select the type of database. After selection, the user is been prompted for database name and then corresponding tables present in that database is been displayed from which the user can select the table which the user wants to convert. Before conversion, the user can view the table from that the user can check whether the correct table is been selected. The table is been converted and a message will be displayed to the user about the conversion. The converted file will be in the XML format and it is been previewed to the user in the database format after conversion. Here, the user can check whether all the fields in the table are converted. While converting the data’s in the tables, the tables present in the database remains unchanged and the fields from the tables retrieved are subjected for XML conversion.

    Database Normalization and Service Request Sr-ta-001

    This memo is to inform you that your service request SR-ta-001 has reached my desk and currently is in the process of being completed. The purpose of this memo is to report the progress on the service requests. Currently I am in the stage of normalizing the database to the third normal form. By normalizing the database to the third level of normalization I will ensure that the data is efficiently organized within the database by removing duplicate and redundant data from the database relations. Normalizing the data to the normal third will help free up space and make it easier for the users to retrieve the data by elimination of the same data stored in more than one relation. In addition, normalizing to this level will also ensure data integrity, scalability, and storage efficiency. I have made sure that that there are no repeating columns or rows within the same tables and each column has only one value and one data type therefore the level of 1 normalization has been completed. I then continued to normalize the database to the second level of normalization by ensuring that each nonkey attribute is fully dependent on the key columns of the table. Once level one and two normal form had been completed I continued by establishing primary and foreign keys along with relationships. I will keep in contact with you as the project nears completion.…

    Exploring Programming Languages

    1.) There have been several versions of SQL created in the last 26 years. In 1986, SQL-86 (SQL-87) was first published. In 1989, SQL-89 was a minor revision made to the original SQL. In 1992, SQL-92 (SQL2) was a major revision to its previous version. In 1999, SQL-99 (SQL3) added regular expression matching, recursive queries, triggers, non scalar types and some object oriented features. In 2003, SQL-2003 introduced XML related features, standardized sequences, and columns with auto generated values. In 2006, SQL-2006 defined ways in which SQL can be used in conjunction with XML and it defined ways of importing and storing XML data in an SQL database, manipulating it within the database and publishing both XML and conventional SQL-data in XML form. It also enables applications to integrate into their SQL code the use of XQuery. In 2008, SQL-2008 Legalized ORDER BY outside cursor definitions, added INSTEAD OF triggers, and added the TRUNCATE statement. As of March 2012, the newest SQL was released its new features include AlwaysOn SQL Server Failover Cluster Instances and Availability Groups which provides a set of options to improve database availability, Contained Databases which simplify the moving of databases between instances, new and modified Dynamic Management Views and Functions, programmability enhancements including new Spatial features, Metadata discovery, Sequence objects and the THROW statement, performance enhancements such as ColumnStore Indexes as well as improvements to OnLine and Partition level operations and security enhancements including Provisioning During Setup, new permissions, improved role management and default schema assignment for groups…

    Case Study Director's Request for Pcs- Part 2: Vendor Database (Ms Access)

    This exercise will introduce you to the basic building blocks of any database – fields, records, and files (also called tables). Although you will create a database with a single table containing a small amount of data about computer vendors, the more applicable use of databases involves the creation of many tables linked together with a common field or “key.” Regardless of the size of the database, the data is stored in the same way – in fields which are combined to create a record. And those records are stored in a file or table. The data is entered into the field via a data entry form, and the information is extracted (to answer a particular question or need) via reports and/or queries.…

    XML is a universal data standard and thereby does not need to be translated for use in different database systems. This is very important with large corporate data systems. In companies that have web presence this is a vital concern where some of the data base systems are handled by external companies that use an entirely different database system. Rather than creating a program to make the translation between that databases XML makes the data readable by both database systems by sharing a schema.…

    Relational Databases

    Data for our programs are stored in various formats. The most commonly used format is in the form of a database since databases are not dependent on a single program or hardware platform. These databases are stored in five structures of hierarchical, network, relational, multidimensional, and object-oriented. Hierarchical structure organizes data in a one to many relationship. The network goes of the hierarchical structure by organizing data in a many to many relationship. The relational structure organizes the data in tables and allows the end user to determine the relationship at run time. Multidimensional takes the relational structures concept and uses multi dimensions to organize the data. Object-oriented structure has not only the attributes of the entity, but also contain the operations that can be performed on it.…
