The database community has developed a series of guidelines for ensuring that databases are normalized. These are referred to as normal forms and are numbered from one the lowest form of normalization, referred to as first normal form or 1NF through five fifth normal form or 5NF.
Fifth normal form is very rare. Remember, these normalization guidelines are collective. For a database to be in 2NF, it must first fulfill all the criteria of a 1NF database. Data Dictionary The term "data dictionary" is used by many, to denote a separate set of tables that describes the application tables.
The Data Dictionary contains such information as column names, types, and sizes, but also descriptive information such as titles, captions, primary keys, foreign keys, and hints to the user interface about how to display the field.
The data volume of this table is less, since number of employees in the clinic is about three to four users. So there is no need for index as well as making a view. Data volume of this table is very large and it can reach Gigabit GB , because of number of patients that visits the clinic daily and we can say at least 50 patients come every day. Data volume of this table is the smallest table in the whole database, and the reason is that there is one doctor in Abokor Artan Dental Clinic and because of that; there is no need an index.
Appointments: The table of appointments also has its own primary key that is Patient ID Also this is a foreign key Fk which is referring patient Registration table. Volume of this table is like Patient table and more, since one patient may take more appointments. It is necessary to make an index for this table.
Complaints: Table of complaint has it is own primary key Pk which is Patient ID which is, at the same time a foreign key of table patient Registration.
It will be nice if we make an index for this table. View and index is good for this table in order to enhance its performance since more data will be stored on it. ADO is also used by VBScript, which is a specialized language that is used primarily to program functionality for web pages. NET is a data access technology from Microsoft. Net Framework , which provides communication between relational and non-relational systems through a common set of components. NET was built for a disconnected architecture, so it enables truly disconnected data access and data manipulation through its Dataset Object, which is completely independent from the Data Source.
The two key components of ADO. Net Framework. NET Framework serves as a bridge between an application and a data source. A data provider is used to retrieve data from a data source and to reconcile changes to that data back to the data source. Core classes of the. Dataset Dataset object is the core of the ADO. NET disconnected architecture and is used to store data in a disconnected state in which there is no need to have a live connection. It contains data table in which data row and data column is present.
Benefits of ADO. Because XML is the format for transmitting datasets across the network, any component that can read the XML format can process data.
Maintainability In the time working systems need maintenance, changes are possible, but substantial, architectural changes are rarely attempted because they are so not easy. That is unfortunate, because in a natural course of events, such considerable changes can become necessary. NET data components in Visual Studio encapsulate data access functionality in various ways that help you program more quickly and with fewer mistakes.
Scalability ADO. NET accommodates scalability by encouraging programmers to conserve limited resources. Because any ADO. NET application employs disconnected access to data, it does not retain database locks or active database connections for long durations. Visual Basic. NET, is an object-oriented computer programming language. NET Framework. To implement this system we will use visual basic. What is a. NET is a platform that provides a standardized set of services.
And it exports a common interface so that its programs can be run on any system that supports. NET: 1. First of all, VB. All features of the. NET framework are readily available in VB. NET, which follows the disconnected paradigm. Platform independent. Easy to debug and maintain.
Event driven programming facility. Net version as the front- end for developing my project. Back-end selection: Microsoft SQL Server is a computer application used to create desktop, enterprise, and web-based database applications. It is used at different levels and with various goals. Multiple user support. Efficient data retrieval and maintenance 3. Stored procedures. As shown below. This means that access to the system is not granted unless a correct user name and password is given.
This means that if an incorrect password is entered access to the system is not approved. Add Patient button will save contents of the controls after you confirm to save the record. In order to update or modify the information of a patient, first search the patient that you are going to modify his information then load to this form by clicking search button.
Delete button also work with the search button, by selecting the record that you are going to delete. Finally Close button: when you press close button, you will be asked whether you are going to close the form or not.
To demonstrate these steps see this picture. To make changes to this record, first search as usual the record then load the data to their textboxes. Can be implemented with the same characteristics. Testing Methods The box approach Software testing methods are traditionally divided into white- and black-box testing.
These two approaches are used to describe the point of view that a test engineer takes when designing test cases. Testing Levels Tests are frequently grouped by where they are added in the software development process, or by the level of specificity of the test. Unit testing Unit testing refers to tests that verify the functionality of a specific section of code, usually at the function level. Ronald Joshua B. Documents Similar To Plumbing Ventilation.

Popular in Mechanical Engineering. Biswajit Das. Accessory brackets can also be utilized to add work trays or additional instrumentation to the sides of the delivery system. The customizable configuration allows ergonomic and efficient hand access to the instruments you need when you need them. Consider designing your system to neatly integrate computer monitors, USB connection ports for digital radiography, CPUs, 3D microscopes, camera recorders and any additional required cabling within the system with convenient access.
This makes the entire system your communication control hub from treatment instruments to diagnostic devices. Patient Experience Opportunity — Adding a computer monitor on top of the delivery system is an easy method to make it look less intimidating and more diagnostic. Patients have become accustom to a wide range of hospital diagnostic units, such as ultrasound devices that look like mini computer carts. Making the treatment unit resemble more of a medical diagnostic cart elevates the specialization of your practice, and makes it more disarming at the same time.
Having a front side monitor is also ideal for providing patient education and treatment planning. Convey the ultimate perception to your patient that the treatment they are receiving is a highly specialized procedure from someone with true expertise. Use internal cord management and storage within the cart to neaten the appearance of the delivery cart. A single umbilical allows compressed air, suction, electrical and computer data cables network, USB, video to be neatly organized and routed to either an In-Wall or In-Floor Junction box.
Foot Control Placement An aspect of a new dental operatory design to consider during architectural planning is the placement of the foot control.
The foot control tubing can be run underneath the floor through a conduit from the junction box to the patient dental chair. The end result creates easy access to the foot control without tubing running across the floor. Now there are advanced choices in how the utilities and data connections will be made to power the delivery systems.
Dentists can choose from a number of modern junction box configurations or to use self contained carts that have an on-board internal air compressor and suction systems. Dental Junction Boxes Select from a modern style of dental junction boxes to efficiently manage, conceal and protect your dental operatory air, suction, electrical, computer data cables and chair controls.
The In-Floor and Above Floor models are generally placed at the foot of the dental patient chair and can provide ambidextrous use of a cart to be moved on either the right or left side of the room. The In-Wall Model is placed in the side wall of the treatment room and allows the dental cart to be placed up to the wall for a neat appearance. Plumb Free Connections Self-Contained Dental Carts with internal compressed air and vacuum only require a connection to a standard electrical outlet for operation.
This makes their placement in the room very flexible and adaptable. Do you need to hire a dental architect? Carefully select who is going to design it and determine if they have experience with the nuances of dental operatory design including utilities, med gas and ideal technology connections.
Some dentists and specialists choose to use the design services of a dental distributor, and others elect an architect that specializes in dental office design.
Your decision should depend on the extent of your project, and should be influenced by whether you are renovating an existing dental space or planning complete ground-up building construction. Your evaluation should also include cost and style factors. STEP 2: Select the Dental Treatment Room Layout and Size Once you have determined your office design goals for a distinctive operatory optimized for treatment, the next step is to decide which type of treatment room style will work best for you.
