`ducky`	`4. Expect ations`
`ducky`	`5. Questions`
`ducky`	`1. What is Midas ?`
`ducky`	`Midas is an open set of tecnical specifications which define a`
`generic model oriented to the Financial/Administrative Software`
`implementation initially for comercial/or service's enterprises.`
`ducky`	`Is a documentation repository which pretend a standard for the`
`FAS (Finnancial Accounting Software )tools design.`
`ducky`	`The project's purpose is to encourage multiple implementations`
`or different modules written in different languages.`
`ducky`	`In short, Midas ITS NOT A FINNANCIAL ADMIN SOFTWARE, Midas is`
`an open design for the FAS implementation or components of the same in`
`different languages.`
`ducky`	`2. Justification.`
`ducky`	`- The existant free projects were designed specifically for`
`some countries or at least they present functionality differences (and`
`resources comsumption) related to local needings (we already verified out).`
`ducky`	`- The project's documentation about their design is very poor`
`(at least when we began the research about in the art state). Adicionally in`
`some of the existant`
`MJesus`	`jaime startlog`
`jaime`	`MJesus: Estoy logueando el canal #redes en [http://felix.zapto.`
`org/jaime/redes.html]`
`ducky`	`ok`
`ducky`	`projects the information in the persistency 's mechanisms`
`(database), table's names and fields were found codified which make very`
`complex to understand its structure and its respective relations between the`
`tables.`
`ducky`	`GNUe's case: we found extensive documentation (in English)`
`about its design but no any concrete implementation which could give us any`
`light. Adicional, our initial idea was trying to be simple and concrete,`
`because GNUe was very complex to assume.`
`ducky`	`3. Design's bases`
`ducky`	`3.1 Needs`
`ducky`	`Thinking about the enviroment which it was Midas designed for,`
`we found what in Colombia, y a Latinoamerica's big part, exist serious`
`limitations related to`
`ducky`	`their infrastructure in telecomunications (common dialup`
`lines), which the digital information must be trasmited.`
`ducky`	`In the case of many enterprises which have many branches or`
`have sub-enterprises of different geographical places, and their connection`
`needing is imperative.`
`ducky`	`The FAS software we can found in the actuality in the our local`
`marketing its not`
`ducky`	`designed to work in efficent way under the given conditions`
`before (dialup`
`ducky`	`lines / limited bandwith)`
`ducky`	`In our case (Colombia), in these moments theres no any free`
`solution adaptable`
`ducky`	`to the enterprises needs and no any commercial solutions at low`
`price are very`
`ducky`	`limited.`
`ducky`	`On the another side, the functionally viable solutions, are`
`commercial and their`
`ducky`	`prices are too high, wich in some cases can beat the actives of`
`an small`
`ducky`	`enterprise, which is absurd.`
`ducky`	`Some groups, have been customizing toos, like SqlLedger, (a web`
`solution,`
`ducky`	`s/toos/tools/g`
`ducky`	`under the client/server model, where every data processing, is`
`performed at the`
`ducky`	`server side), which on Intranet based enviroments, (LANs at`
`10-100 mb/s), seems`
`ducky`	`to work very well.`
`ducky`	`In these moments we know about some proyects at national`
`level, which are`
`ducky`	`interested in fill this empty, what in present time we know`
`about free SAF`
`ducky`	`software.`
`ducky`	`nevertheles, under our particular vision, in the SqlLedger`
`case, we didnt use to`
`ducky`	`share the fact about any kind of client's request have to`
`travel, to the server`
`ducky`	`once and another time`
`ducky`	`including data have been already transmited in early operations`
`ducky`	`We havent done the test, but we would like to see sqlledger`
`working`
`ducky`	`trough a dialup line`
`ducky`	`doing an excercise where the enterprise, have an 500`
`processe/services stock`
`ducky`	`Aditionally, what would happen if i have a supermarket, with 30`
`terminals,`
`ducky`	`(486)`
`ducky`	`and i wanna implement a FAS system?`
`ducky`	`if i choose sqllegger, ill be in the duty, a graphical`
`environment`
`ducky`	`in order to open a web browser`
`ducky`	`(sqlledger supports text-based browsers)`
`ducky`	`yea..we already know`
`ducky`	`but a text-based browser for the girl who is at the box?`
`ducky`	`"use LTSP and problem solved"`
`ducky`	`..would say some people..`
`ducky`	`but and what happen if we wanna free the central server`
`ducky`	`of the load of the X clients`
`ducky`	`its clear, in a LTSP scheme`
`ducky`	`concentrates the all the processing in a single point : the`
`server`
`ducky`	`aditionally, we sum the resources, used by the FAS system`
`ducky`	`remember, we are talking about 30 online selling points`
`ducky`	`why cant i use terminal mode clients (ncurses,etc)?`
`ducky`	`if i would like the database in another server`
`ducky`	`?`
`ducky`	`or if i already have particular database motor and i wanna use`
`in the implementation`
`ducky`	`?`
`ducky`	`could it be possible to offer a platform- indepent system?`
`ducky`	`programming language indepent`
`evanginee`	`does anybody have a log of the talk/discussion so far?`
`evanginee`	`on Midas?`
`ducky`	`why not to offer an FAS architecture, which let clients, and`
`servers`
`ducky`	`evanginee, [http://felix.zapto.org/jaime/redes.html]`
`ducky`	`:)`
`evanginee`	`excellent, thanks ducky`
`ducky`	`joining to the infrastructure`
`ducky`	`and enteprise's needs?`
`ducky`	`3.2 Module Definition`
`ducky`	`Analysing this needs, we began to delimit, a design what would`
`be compilant with the requests, of the existant demand`
`ducky`	`in conectivity terms`
`ducky`	`aivability`
`ducky`	`hardware aivability`
`ducky`	`and funcionality`
`ducky`	`(we based on open develoment model)`
`ducky`	`Initially the design is composed of the following`
`ducky`	`modules`
`ducky`	`in the functional part`
`ducky`	`Accounting module:`
`	`holas`
`	`este server no se supone q debia ser japones?`
`fernand0`	`no`
`	`ah`
`	`jo`
`	`y de q es este server?`
`ducky`	`it starts on the suposed, of what the accouting should be the`
`result of the transactions done, by the software in some time`
`ducky`	`This module has the capability to generate, the necesary reports`
`ducky`	`in order to achieve`
`ducky`	`the right administration on the enterprise`
`ducky`	`among of them, balances`
`ducky`	`GyP(lost, and gains)`
`ducky`	`Box flow`
`ducky`	`Official books (Major, diary, summary)`
`ducky`	`Stock module:`
`ducky`	`in charge of the management, of the client's state`
`ducky`	`and accounts`
`ducky`	`which lets client's identification`
`viva UMEET!)`
`ducky`	`wholesalers`
`ducky`	`retailers`
`ducky`	`and making of their respectives stadistic resports`
`ducky`	`or account's status reports`
