The Computer Resource Management System

The estimator Resource Management strategyA Computer Resource Management System is utilise to get up to date randomness of all in all the computer resources in an arranging. It is basically a management and informative placement. This arrangement helps the government activity to overcome the complexness in tracing proscribed all the computer resources of the organization by presenting customised reports, there by helps in effective and timely utilization of hardw be and mail boat package resources.Computer Resource Management System uses the Enterprise JavaBeans Version 1.1 its the component model for the enterprise applications. Enterprise JavaBeans combines server-side components with distri b arelyed object technologies such as Java RMI to greatly simplify the task of application development. The EJB automatically takes into account umteen of the requirements of business establishments tribute, resource pooling, persistence, concurrency and effectal integrity.On e of javas most important features is platform indep prohibitence. Since it was released, Java has been marketed as preserve once, run anywhere. Enterprise JavaBeans is not only platform independent -its excessively implementation independent. Its like JDBC API runs on a Windows machine or on a Unix machine, it tin access any vendors relational database that has a JDBC driver. Ideally, an Enterprise JavaBeans component, an enterprise bean, grass run in any application server that implements the Enterprise JavaBeans (EJB) specification. That is we can develop and deploy EJB business dodging in one server, such as BEAs Web logic and later move it to a different EJB server, such as IBMs Web Sphere or Gemstone/J. Implementation independence means that business components are not dependent on the brand of server.Computer Resource Management System uses Oracle 8i as the back-end RDBMS. Oracle 8i is actually a fully Internet supported database system. Oracle 8i perfectly handles the A CID Transactions. A performance is the execution of a unit-of-work that accesses one or more shared resources, usually databases. A unit-of-work is a set of activities that relate to each different and mustiness be completed together. The ACID properties are nothing but (Atomic Consistent Isolated Durable) propertiesA feat to be atomic, it must execute completely or not at all. Consistency refers to the integrity of the underlying data store, consistency is ensured by seeing that a transaction is atomic, isolated and durable. Isolated refers to allowing a transaction to execute without interference from other processes or transactions, i.e., the data that a transaction accesses cannot be affected by any other part of the system until the transaction or unit-of work is completed. Durability means that all the data changes make during the course of a transaction must be written to around sheath of physical storage before the transaction is successfully completed. This ensures th at the changes are not lost if the system crashes. Apart from intervention the ACID properties Oracle 8i has higher aegis level and web compatibility features.2. Problems of Present SystemAs of now the resource management in SOFT PRO SYSTEMS LTD is done manual of armsly. If an employee intends to know the information regarding the resources pertaining to computers or components and their present and accurate information in the organization, as of now it is being done manually which consumes a great manpower and the process is time consuming. The conundrum of maintaining the bulk database can be solved by atomizing the resources in the organization, which can be of great help to all the administrators, employee and the management members.Some of the frequent occurring problems in the present manual system are as followsFinding the ongoing status or position of a component in the organization is a time-consuming process.The Manager has to wait for the manual reports from the deve lopment department to know the current status of the resources.In the present system there is no auspices for the details of the resources as any user who is not authenticated to view the records may see them.To view the details of a computer and to know what are the components that are delegate to it, can be done only by a manual checking of that computer for the hardware and software components is a tedious process.The users of the organization require dissimilar reports to be generated in an easy format, which is not so easy when done manually.The Manager may get problems in finding out a user details in hundreds of records.2.1 Need For ComputerizationMaintaining the information regarding all employees, components and computers at single or multiple locations bestow rise to many problems likeDifficulty in retrieval of data in desired manner.Checking the uniqueness wherever it is required.Availability of information in this manner is subjected to damage.Providing protection is also difficult.One way to overcome all these difficulties is to store all the information in the computer. The computerization helps the users a lot. The user can get information in desired manner. Data retrieval is also easy and fast. This also restricts the users to enter invalid data and reduces the burden on the user.2.2 Benefits of ComputerisationA computer establish information system is usually needed for the following purposes.Greater Processing SpeedUsing computers inherent ability to calculate, sort retrieve data with greater amphetamine than that of the charitable doing and can get results in less time. Visual basic guaranties for the faster query processing thus we are satisfied with Visual Basic itself supporting in this direction.Better Accuracy and Improved ConsistencyThe computer carries out computing steps including arithmetic accurately and consistently from which really human is escaped which yields more fatigue and boredom.Cost ReductionUsing computerization we can do the required operations with lower cost than any other methods. Hence by computerization we can reduce the cost drastically.3. Modules of CRMSOf course there are many other systems which can maintain all the resources of the company, but there are some defects and difficulties in those systems regarding security and HR dependent issues. The Computer Resource Management System mainly consists of 6 modules and a brief explanation of those is effrontery below. (Overview of Metadata Annotations and EJB 3.0 Bean Files, 2009)1 ComponentsEach and every component that is either related to software or hardware leave be assigned with a unique number and entered in to a folder or shelf. Whatever goes out will be deducted from the shelf and must be entered either to bin, recycle bin or to a computer. For every component appropriate entry should be made.2 ComputersComputers will be assembled using the shelf parts. each computer should be given a unique number. The details of the c omputer will be entered including its hardware and software profiles with their parts. The computers may be servers, standalones and clients etc.3 BinThe damaged components, which are not repairable or replaceable, will be sent to this bin.4 Recycle BinThe repairable and replaceable parts will be kept here. A time report is given like when a part is submitted for repairs or replacement and expected back time and able to give warnings of delays etc.5 StatusThe status gives the statistics of the shelf, bin, recycle bin, computers. The status gives the present position of the component where it is situated in the organization. Basing on the status the components are utilise in different transactions.6. Search / ViewThe users can search or view the information of different resources based on their unique number given to them.The proposed system will be designed by using Java beans as front end and Oracle 8i as RDBMS of the system that is oracle as back end of the system. Hyper school text mark-up language is used to hyper text the information which can be moved from one platform to other, and JDBC concepts will be used.4. epitome of the get windSystem Planning is one of the important items to be considered before actually beginning the project. Planning is performed on the issues like defining Life round Model and an organizational structure project, configuration management, quality and validation activities.In the process of the System Planning different kind-dependent tools, techniques and notations are determined. Preliminary cost estimates for the system development and preliminary development schedules are established. Preliminary estimates of the computing resources required to operate and maintain the system are real, glossary of terms are prepared.4.1 discipline GatheringInformation relevant to the Computer Resource Management System of Laila Infotech is collected from the Laila Infotech Limited and the finance department of the company. The info rmation regarding company activities is gathered from the companys website www.lailainfotech.com.4.2 feasibility StudyAn initial investigation culminates in a proposal that determines whether an alternative system is feasible than the present candidate system. To do feasible study we pack to do Economic, Technical, Behavioural feasible studies.4.2.1 Economic FeasibilityIt is the most frequently used method for evaluating the effectiveness of a system. It is also called as cost/ realize abbreviation.In this project Computer Resource Management System, for the development of the candidate system the costs that have to spend is the computer resources like the required software and hardware that supports the software in an effective and efficient manner and the money to be paid to the developers. As the company itself is a development centre all the resources are in the company itself and no extra cost are spent for Computer Resource Management System. Hence our candidate system tak ings is economically feasible.4.2.2 Technical FeasibilityTechnical feasibility centres on the existing computer system (software/hardware) configuration and good software facilities in such a way that any new candidate system can be implemented without a large alteration of the lab nut with slight revision of the existing system. Hence our candidate system production is technically feasible.4.2.3 Behavioural FeasibilityPeople are inherently resistant to change. Our candidate system is genuine in such a way that it is very user friendly, easy to learn how to work with and there is also not much resistant to this package from the staff side also. As the company is basically a development centre it will be very easy for the employees of the company to learn approximately the developed candidate system. Hence our candidate system production is behaviourally feasible.5. ConclusionThis project aimed at developing a Computer Resource Management System (CRMS) is a total management and in formative system, where up-to date information of all the computer resources in the company can be provided. It helps the companies to overcome the difficulties in introduce the resources of the company by presenting customized reports, which helps the company to effectively and timely utilise hardware and software resources. partsDavid Austin., (2000), Using Oracle8, Eastern Economic Edition, 2000 Edition.Overview of Metadata Annotations and EJB 3.0 Bean Files, Retrieved march 15, 2009 from http//e-docs.bea.com/wls/docs100/ejb30/program.htmltypical_stepsPatrick Naughton., and Herbert Schildt., (1999),The Complete Reference Java 2, TATA McGRAW-HILL., 1999 Edition.Pressman, R., S., software product Engineering A Practitioners Approach, seventh edition, Retrieved 06 march, 2009 from http//www.rspa.com/spi/Roman, Ed.,(1999), Mastering Enterprise Java Beans and the Java 2 Platform, Enterprise Edition, WILEY., 1999 Edition.Tom Valesky., (2000), Enterprise JavaBeans, Pearson Education As ia, 2000 Edition.Project proposal1. IntroductionA Computer Resource Management System (CRMS) is used to get up to date information of all the computer resources in an organization. It is basically a management and informative system. This system helps the organization to overcome the complexity in tracing out all the computer resources of the organization by presenting customised reports, there by helps in effective and timely utilization of hardware and software resources.A transaction to be atomic, it must execute completely or not at all. Consistency refers to the integrity of the underlying data store, consistency is ensured by seeing that a transaction is atomic, isolated and durable. Isolated refers to allowing a transaction to execute without interference from other processes or transactions, i.e., the data that a transaction accesses cannot be affected by any other part of the system until the transaction or unit-of work is completed. Durability means that all the data chan ges made during the course of a transaction must be written to some part of physical storage before the transaction is successfully completed. This ensures that the changes are not lost if the system crashes. Apart from handling the ACID properties Oracle 8i has higher security level and web compatibility features.2. Background of the projectThe purpose of proposed system is to provide a computer based system which can manage total resources of an organization. In preceding systems the resource management was done manually, which wastes so much of time and the man power. The most important thing is the lack of security in previous resource management system. The atomized management system is efficient enough to maintain the resources. The development of the proposed system is needed for so many reasons such as security aspects, ease of use for the employees of organization. The disadvantages of the paper based or existing system can be rectified by implementing the proposed system .The disadvantages of paper based system are mentioned belowFinding the information slightly a component in the system is difficult and time taking course of action.In the existing system any user, who is not authenticated can also view the information and change it, which leads to poor design and implementation of the total system.A lot of manual work is required in finding and generating the reports about various sections in the organization, because of this work people can become irritate and get bored of doing the work.The employees of the organization must produce the reports in a simple and understanding way, generating of such reports is not that easy to do.Authentication of a user cannot be given in the existing system, and there is so much difficulty in taking out and recovery of data in a preferred manner.The present system is going to provide the security to the database, and atomizing the system to manage the resources in the organization by using the enterprise java be ans, oracle 8i as front end and back end of the system. To develop this system a good knowledge about life cycle model of software development, different functions of the organization and about marketing strategies is required. The knowledge of various reports that are to be generated which are helpful to different branches in the organization is required. In the development of the proposed system the different phase dependent tools, methods and document specifications are determined. (Roman, 2002)3. Aims and objectivesAimTo design an automated computer based system and to get up-to-date information about components which helps organizations to conquer the complexity in tracking all the resources of the company by generating reports that are more easily understandable and to improve security for database. It provides proper initiatives and approaches that need to be undertaken, thereby avoiding the huge cost of implementing a new system or by simply adapting to one currently deploye d.ObjectivesThe main objectives of this study are as follows The main objective of Computer Resource Management System is to provide an automated system to maintain the resources of the company.To provide a user friendly and multi-user interface for handling the application.To provide a user authentication and different interface depending upon the type of user logged in.To provide maximum level of security for the data.To provide the necessary reports to various users in time.4.

Design is maintaining a record proof design division and providing a blueprint for the implementation phase. Design is the bridge between system analysis and system implementation.System design is transition from a user oriented, document oriented to programmers or database personnel. The design is a solution, a how to approach to the creation a new system. This is composed of several steps. It provides the understanding and procedural details necessary for implementing the system recommended in the feasibility study. Design goes through transparent and physical coiffures of development, logical design reviews the present physical system, prepare input and o utput specifications, detail the implementation plan, and prepare a logical design walkthrough. (Dennis, A. Wixom, B. H. (2000))The database tables are designed by analyzing various functions involved in the system and the format of the field is also designed. The fields in the database table should define their role in the system. The unnecessary fields should be avoided because it affects the storage areas of the system. Care is to be taken to encode the lengthy names. Then in the input and the output screen design, the design should be made user friendly. The menu should be precise and compact.4.3.1 Objectives of DesignSystem design is like a blue print for a building, it specifies all the features that are to be in the finished product. Design states how to accomplish objectives determined in the analysis phase.Logical DesignThe design of an information system produces the details that state how a system will meet the requirements identified during systems analysis. This stage is login design.Physical DesignThe process of developing program software is referred to as physical design. In this stage the logical design elements are specified which support the business activities. The physical design ensures the system features to meet the user requirements.5.
