    I think this relates to database development in a number of ways. One is how it starts, gathering information and finding the intent of the system. Next you must plan out how to set up the database, which is the vital information? What are the minor details? Then you set up your database fill in some test information insure it works properly and make needed adjustments. Finally you implement your database design where in it works properly you merely maintain and fix any errors.…

    If we are going to develop Database, we might as well make it look good. By doing this, we can improve the database ability to provide information and to enhance the operational characteristics. It is important to understand that normalization cannot be relied on to make designs by itself but will need to by create separately. The following two methods can be used to improve the design of database system.…

    A. Lab # : BSBA BIS245A-1 B. Lab 1 of 7 : Introduction to MS Visio and MS Access C. Lab Overview--Scenario/Summary TCOs: 1. Given a business situation in which managers require information from a database, determine, analyze and classify that information so that reports can be designed to meet the requirements. 2. Given a situation containing entities, business rules, and data requirements, create the conceptual model of the database using a database modeling tool. Scenario: You have been asked to create two conceptual database models using MS Visio Database Model Diagram Template. The purpose of this lab is to have you gain familiarity with the various modeling tools needed to create a conceptual model (entity relationship diagram) of a database. You will create two conceptual models. You will then open an existing Access database to explore database objects and to experiment with simple data manipulation using filters and sorts and to begin elementary work with relationships. Upon completing this lab, you will be able to 1. relying on detailed instructions, create a simple conceptual model for a two-table database using MS Visio; 2. use experience gained in creating the first model to construct a similar conceptual model without the instructions; and 3. download an existing Microsoft Access database file. Open the database; find and identify different database objects in this database.…

    Tables that contain redundant data can suffer from update anomalies, which can introduce inconsistencies into a database. The rules associated with the most commonly used normal forms, namely first (1NF), second (2NF), and third (3NF). The identification of various types of update anomalies such as insertion, deletion, and modification anomalies can be found when tables that break the rules of 1NF, 2NF, and 3NF and they are likely to contain redundant data and suffer from update anomalies. Normalization is a technique for producing a set of tables with desirable properties that support the requirements of a user or company. Major aim of relational database design is to group columns into tables to minimize data redundancy and reduce file storage space required by base tables. Take a look at the following example:…

    Functional Dependency is the starting point for the process of normalization. Functional dependency exists when a relationship between two attributes allows you to uniquely determine the corresponding attribute’s value. If ‘X’ is known, and as a result you are able to uniquely identify ‘Y’, there is functional dependency. Combined with keys, normal forms are defined for relations.…
