The science and technology below Windows serves the design of project management system and implementation

9The Design Of Technical DevelopmentMIS Based On WindowsTao Youqing(Dept.

Of Science Researching, nanchang Institute Of Aeronautical Technology)Abstract: Based On The Object-Oriented Design Method, this Paper Presents The Design Thought For Technical Development MIS With Keli Multimedia MIS Generator, and Discusses The Design Of Database Structure And Data-windows.

Meanwhile, main Functions Of The MIS Are Introduced.

Key Words:WIndows, research And Development Management, management Information System.

Introductive science and technology serves the main component that is college scientific research, the side runs in funds, it is different from fore-and-aft with project of free scientific research, because return the collection that involves a series of charge such as taxation, want to consider the case of each respect on the allocation of accrual, because this makes the funds of a project many, computational amount is large. Collect labour of choose and employ persons to undertake administrative working not only apparently strength is great, and efficiency is low, get used to science and technology to serve the increases increasingly need of the project hard. The definition that the process that 1 design train of thought develops a management information system includes to use a system, generate and carry out 3 phase. When service of design science and technology runs software, our main energy is put on functional analysis of the system, on the definition description that uses a system namely. The task that considers a system namely (the goal that should achieve namely, what that finish works) , the organization of the data that task flow, place needs, data, of whole system compositive wait. 1.

The main task of the system of management of service of main task science and technology of 1 system should include the process management of the project, the executive circumstance that makes administrator understands a project in time (if change, stop, finish etc) mix fund condition; The processing of project funds, if the project arrives after the paragraph the computation of all sorts of charge, deduct, to the accumulative total of money specified amount, each department and complete courtyard arrive the collect of money specified amount; The settle accounts of the funds after the project is finished and allocate etc. 1.

The functional analysis system of 2 systems basically should have data to type, data is safeguarded, forms for reporting statistics of statistic of data inquiry, data, data, system is safeguarded wait for basic function. Because division force MIS offerred module of among them major standard and Visual FoxPro almost all accusing a type, accordingly we can ask to choose and set design target according to real function. If batch is revised, current inquiry, current count can choose standard module, data is safeguarded in the project that can hang the design that accept place registers the window and window of project settle accounts. 1.

The data organization database of 3 systems is the foundation of whole system, in science and technology structure of table of service project data is designed in, the setting that we want to consider field of the numerical value in data table above all reachs his mutual the operation between concerns, because project of service of science and technology is numeric the field is much, and mutual the operation relation between is complex, because this is numeric field mutual the key that the operation relation between is the consideration when we are designing data to express. In addition the character field that considers to install a few keys even and logistic field, will determine the value of numeric field according to the content of these fields. Should accomplish data at the same time the watch is clear, concise. 1.

Of 4 systems compositive we accuse through data window, the window accuses, inquiry accuses, menu accuses, and the standard such as cover, statistic, forms for reporting statistics decides patternmaking piece, systematic place is indispensible accuse individually after reaching the window to be finished entirely, finished systematic frame to design namely, apace builds an application system. Systematic classics try out, evaluation, undertake refining mixing according to the opinion that offer augment, end up with the science and technology of a need serves applied system. In recent years, windows technology got popularize and be used extensively, already made the main trend of current operating system, and the occurrence of the MIS development tool below Windows, make we cast off multifarious process designing trouble truly likely. We used home's at present more popular MIS to develop a tool - the design that maker of system of management of division force multimedia will come to to complete a system. The implementation of 2 software we know, the sense that in Windows environment application software gives the person that use is to face each window, and all sorts of components in the window (the) such as casing of pushbutton, menu, list. Because the system was used with " the window " the design method that devises the incident drive that gives priority to a line, its in-house incident drive mechanism makes the switch freely between the window, the concept that past program sheds turned the window into the switch between. We design the design that considers a system for jumping-off place with the window, emphasize at window interface to mix namely design relative to the function at every window interface, whole system needs what window, every window should have what function, spread out a design to work step by step next. The key that we design is put on the design of data table structure and data window. The design of a few main module and component is below: 2.

In the data table that 1 data expresses structural design to serve an item in a science and technology (this system moves below Visual FoxPro environment, also use the notional) that data expresses, build data structure to want to consider the case of tripartite face, it is the fundamental condition of the project on one hand, like number, name, type, entrust square, carry on controller of department, project, period of validity; It is the charge situation that produces in item executive process on one hand, be like fund condition (mix to money specified amount money time) , charge of electricity of decanal fund, administration fee, water, strive for cost and taxation to wait, with arriving every time money specified amount regards computation as base these numeric fields; Another respect is the accrual after the project is finished divide into, welfare fund of the development fund that is like group of department, project, award, these numeric fields regard computation as base with net income. The data list that we build finally has more than 60 field. Besides major numeric field, still have a few crucial character fields and logistic field, be like project type, taxation field. The field content such as charge of electricity of the decanal fund because of the project, water should inspect an item is development or treatment type will deduct different scale, promotive fund also should inspect a project to whether go up capture taxes will decide. Because this is in design of data table structure, between the field operation and the operation after be being judged according to certain field requirement, a when the consideration wants in becoming data to express a structure to design main factor. This is explicit the field is add in attribute, regard only cost as the mark project number, the project repeats and cause computation in order to avoid to repeat. 2.

Window of data of design of 2 data window is the extension of the database, namely the alternant interface between database and user, specific saying is data field on screen arrange a format. The field that serves project data table as a result of whole science and technology is more, it is impossible that will entire field is arranged in a window. Accordingly we designed two windows, one serves as the registering window of the project, the fundamental condition the project, to fund condition, and the cost that produces in project progress all is put in this window, use at the process management of the project; Another regards the settle accounts of the project as the window, the accrual after completing the project and cent are put in this window into the circumstance, use at the later period management of the project. We will have identical character through becoming group circle annual reach its corresponding numeric field to undertake to fund condition in group, make whole window distinct. Our basis " the field edits casing " accuse, the field such as type of square to carrying on, project uses pull-down phrase clew respectively, with achieving the goal that types quickly. And the numeric field that participates in operation to need, pass offerred formulary operation property, all operation the relationship has been defined. We use Iif() function to treat the numeric field that operation has after needing to be judged first. When designing a database to type an interface so, construction gave a function very strong type module, want to input money specified amount only, corresponding numeric field can be calculated automatically come out. A function of the system is collect in those days to money specified amount. Because some items are likely a year in to two moneys, some items are likely paid and total money. To arriving in those days money specified amount, we are installed to arrive every year the accumulative total of money specified amount, the condition is an accumulative total arrive identically to a particular year of money time and systematic date money specified amount. When project settle accounts, still involve the processing issue that completes award to. Because manage method to set, achieve when net income only 10% when, 5% what the award that finish just can draw paragraph specified number, can extract only otherwise 3% . And the computation of net income needs to assume the award that finish is first 5% , such we increased in data table " net income is judged " field, will judge net income to whether can be achieved with this 10% . = of net income judgement arrives money total - direct cost - overhead costs - the award that finish (5%)- arrives money total *10% . In type, direct cost is a purpose to be used up directly, if material, treatment, brigade needs fee,wait. Overhead costs is decanal fund, administration fee to wait, accordingly: Net income of =iif(of the award that finish judges ≥ 0, to money total *0.

05, to money total *0.

Window of 03) 　 data is the container of an object, all sorts of accuse an object to be able to be placed in data window. In data window, the position of field object, size can be arranged arbitrarily, still can accuse with what offer, attribute, font, color, right wait for a function together, and paintbrush, line, picture undertake got-up to the window, still can use sheet or many means, choose one screen to show a record or many record, accordingly we can design interface of beautiful, agile input, output. 2.

What 3 menu design and procedure-oriented programming differ is, in object-oriented visible development environment, the window serves as carry out accuse can hang receive fall in menu, at the same time menu is the window accuse, menu also can be hanged receive fall in the window. The menu of this system is hanged receive in advocate below the window, of menu hang receive install in window attribute. Dish of the function in menu is individual besides can hang outside receiving the window, still can hang receive a standard module, custom-built module and from program. Data is safeguarded medium project is registered and project settle accounts is hanged received a project to register the window and window of project settle accounts. The registering inquiry in data inquiry and settle accounts inquiry also are hanged respectively received window of the inquiry that register and window of settle accounts inquiry. The inquiry that browse, forms for reporting statistics that register and settle accounts forms for reporting statistics are hanged received custom-built module. Data safeguards medium batch to revise, data inquires medium current inquiry, the current count in data statistic, to load of the data backup in data processing, data all is hanged received standard module. 2.

4 cover and advocate the systematic the title page of a thread-bound book that the window designs us to be able to use cover to design a tool to match a rich characteristic or individual character to use a system. If we can use scanner the education the institute advocate the handwritten form of building picture and academic name is defeated into the computer, turn into via processing the setting that cover serves as after BMP image file, input advocate caption " science and technology serves project management system " , undertake got-up to literal color, size, font, position again. Same we also can place a scenery picture that we like to make the background that gives priority to the window, choose paintbrush to accuse next appearance attribute draws an ellipse, choose stereo word to accuse literal attribute is inputted " service of greeting use science and technology runs a system " character, the attribute such as deepness of repass shadow type, shadow, font undertakes got-up to the character, till satisfaction till. System of 3 functions brief introduction basically is typed by data, data is safeguarded, forms for reporting statistics of statistic of data inquiry, data, data, system is safeguarded wait for a part to comprise, we introduce a few main function module below: (1) is safeguarded in data in, we are hanged received a project to register with settle accounts two windows, the system offerred a database to safeguard accuse with the database inquiry accuses, can make we finish a record to increase below window condition directly, revise, delete, inquiry, print the main operation that waits for a database. Revise in batch in, we can appoint a field arbitrarily, define assignment expression. This module allows to define many assignment expression. The user still allows to input a record to choose a condition before executive batch is revised, undertake modification to satisfying conditional record. (Module of 2) current count makes we adopt choice data cause, the definition enters the sort of statistical field and data table in data table. Define statistical operation next, the data that handles like statistic in group, transverse operation is formulary, the statistical result of generation can have a variety of output forms. (3) is in design of forms for reporting statistics, we can use the current forms for reporting statistics in standard module to undertake the output of the project, if choose to need the field of output, forms for reporting statistics in group field, whether sue for peace. We will carry on is to regard as in group field, facilitating statistic fastens each to fund condition. The settle accounts form that serves an item as a result of science and technology is more complex, belong to irregular form, we still can use the tool such as the field that form designs, pane, line, page number, date, realize the design of complex form, make oneself satisfactory settle accounts form come. (4) is safeguarded in the system in, we are special increased to load of data backup, data, phrase to safeguard, index is safeguarded wait for module. Build backup in time to the database; Undertake maintenance to word group library, increase or delete word group; The system is compatible the database that develops with FoxPro, Foxbase, Dbase, the early days that can protect us invests. The moving environment of system of 4 last words is Windows 95 or 98 operating systems, visual FoxPro. Show via using systematic function is strong, master easily, achieved practical the requirement that change. CNC Milling CNC Machining
