Comparison of Traditional File-Based Approach and Database Approach At what is the medical model in health and social care beginning, you should understand the rationale of replacing the traditional filebased system with the database system.

File-based System File-based systems were an early attempt to computerize the manual filing system. Filebased system is a collection of application programs that perform services for the endusers. Each program defines and manages its data. However, five types of problem are occurred in using the file-based approach: Separation and isolation of data When data is isolated in separate files, it is more difficult for us to access data that should be available.

The application programmer is required to synchronize the processing of what is a weak positive association or more files to ensure the correct data is extracted. Duplication of data When employing the decentralized file-based approach, the uncontrolled duplication of data is occurred.

Uncontrolled duplication of data is undesirable because: i. Duplication is file based approach vs database approach. pdf ii. Duplication can lead to loss of data integrity Data dependence Using file-based system, the physical structure and storage of the data files and records are defined in the application program code. This characteristic is known as programdata dependence.

Making changes to an existing structure are rather difficult and will lead to a modification of program. Such maintenance activities are time-consuming and subject to error. Incompatible file formats The structures of the file are dependent on the application programming language. However file structure provided in one programming language such as direct file, indexed-sequential file which is available in COBOL programming, may be different from the structure generated by other programming language such as C.

The direct incompatibility makes them difficult to process jointly. Any required queries or reports have to be written by the application programmer. Normally, a fixed format query or report can only be entertained and no facility for ad-hoc queries if offered. File-based systems also give tremendous pressure on data processing staff, with users' complaints on programs that are inadequate or inefficient in meeting their demands.

Documentation may be limited and maintenance of the system is difficult. Provision for security, integrity and recovery capability is very limited. Database Approach In order to overcome the limitations of the file-based approach, the concept of database and the Database Management System DMS was emerged in 60s. Advantages A number of advantages of applying database approach in application system are obtained including: Control of data redundancy The database approach attempts to eliminate the redundancy by integrating the file.

Although the database approach does not eliminate redundancy entirely, it controls the amount of redundancy inherent in the database. Data consistency By eliminating or controlling redundancy, the database approach reduces the risk of inconsistencies occurring. It ensures all copies of the idea are kept consistent. More information from the same amount of data With the integration of the operated data in the database approach, it may be possible to derive additional information for the same data.

Sharing of data Database belongs to the entire organization and can be shared by all authorized users. Integrity is usually expressed in terms of constraints, which are consistency rules that the database is not permitted to violate. Improved security Database approach provides a protection of the data from the unauthorized users. It may take the term of user names and passwords to identify user type and their access right in the operation including retrieval, insertion, updating and deletion.

Enforcement of standards The integration of what does a qv mean database enforces the necessary standards including data formats, naming conventions, documentation standards, update procedures and access rules. Economy of scale Cost savings can be obtained by combining all organization's operational data into one database with applications to work on one source of data.

Balance of conflicting requirements By having a structural design in the database, the conflicts between users or departments can be resolved. Decisions will be based on the base use of resources for the organization as a whole rather that for an individual entity. Improved data accessibility and responsiveness By having an integration in the database approach, data accessing can be crossed departmental boundaries. This feature provides more functionality and better services to the users.

Increased productivity The database approach provides all the low-level file-handling routines. The provision of these functions allows the programmer to concentrate more on the specific functionality required by the users. The fourth-generation environment provided by the database can simplify the database application development. Improved maintenance Database approach provides a data independence. As a change of data structure in the database will be affect the application program, it simplifies database application maintenance.

It ensures no interference between users that would not result any loss of information nor loss of integrity. Improved backing and recovery services Modern database management system provides facilities to minimize the amount of processing what is the role of acid and bases in body fluid can be lost following a failure by using the transaction approach.

Disadvantages In split of a large number of advantages can be found in the database approach, it is not without any challenge. The following disadvantages can be found including: Complexity Database management system is an extremely complex piece of software. All parties must be familiar with its functionality and take full advantage of it.

Therefore, training for the administrators, designers and users is required. Size The database management system consumes a substantial amount of main memory as well as a large number amount of disk space in order to make it run efficiently. Even after the installation, there is a high recurrent annual maintenance cost on the software. Cost of conversion File based approach vs database approach.

pdf moving from a file-base system to a database system, the company is required to have additional expenses on hardware acquisition and training cost. Performance As the database approach is to cater for many applications rather than exclusively for a particular one, some applications may not run as fast as before. As all users and file based approach vs database approach. pdf reply on the database availability, the failure of any component can bring operations to a halt and affect the services to the customer seriously.
