Architecture :: Design For Easy Integration Into Customers Websites?
Aug 22, 2010
The project, once done, will provide a "portal" into a limited portion of the client's database. All clients are using a SQL database, but various server software products are involved (MSSQL, MySQL, and others).
My question, however, has more to do with the "look and feel" of the finished product. We want to be able to integrate our 'portal' easily into the client's websites and have it look as seamless as possible. Obviously, placements of logos, etc. -- but also colors, fonts, etc.
Client sites tend to be simplistic in design. We envision the customer placing a link to our site from theirs, and our site will be running on IIS on their server. At least that's the plan.
The goal right now would be to make as much of this "parameter driven" as possible, so that a lot of the install can be accomplished through some simple settings, isolated in one or two files such that at installation time we can tweak those settings and be up-and-running in a short period of time with a site that integrates reasonably well with the customer's.
But I'm uncertain as to whether there is a better approach. Obviously, we could try to redesign our site with each install with the basic design of the customer's, but this would be cost-prohibitive in some situations. So, I'm thinking about a "second best" alternative that may be adequate in most circumstances.
I am currently developing a solution in which the user logs in once and can work on multiple customers at the same time on my site.I've looked at all possible solutions involving sessionid having stored the customerid, to launching a new browser session so i could have multiple sessions for one users etc. I also looked at using cookieless sessions.But the all fail because it's not a simple solution and in my opinion a simple solution is most of the time a good and predictable solution.
Therefore i came up with the idea to use url rewriting(i've seen this used in other applications). When the user opens a customer, i would like to start his url as follows "~/Customers/xxxxxxx/*.aspx" where xxxxxx represents the customerid. and *.aspx represents a complete subset of pages of my site. This would allow me to use a simple technique to use multiple user sessions within a single asp.net session.
Now coming to my problem, I have never done some url rewriting, therefore my questions:
- Is this possible.
- Can i protect all the pages that need a customerid as input(come to think of it, if no customerid in the querystring, redirect to a selection screen would be sufficient).
- How do i adopt all urls used in a sitemap etc in a structured way.
We're doing a data integration project between a MS Sql Server database and a Microsoft CRM system (through its web services).
We're trying to build a "service" layer on top of the database. The design of our current solution is to use web services for CRUD, with xml being the format of data.
Views are created to consolidate related tables into one entity, and we query these views, using the "SELECT * FROM someview " + "For XML" to generated xml that will be returned from our web services.
For update we're trying to use the same approach - using SQL XML to map updates views, we have "instead of" triggers defined on top of these views, and in these "instead of" triggers we update the underlying tables.
The views/triggers are generated by tools so don't be too concerned with coding efficiency here...
what do you think if we use WCF data Provider to publish a enterprise data model (essentially DTOs) ? p.s., we don't have a BL layer for now, it's all in the stored procedures!!!
I'm not too sure where to ask this question, and forgive me for the lack of research, but I have a meeting coming up this afternoon, and need the skinny on interfacing my asp.net web apps with ms dynamic crm.Basically I have the ms sql layer that is custom to my apps. Then I have the application layer, built in asp.net. This is basically connecting web forms and reports to a sql database. (Sounds so simple when put that way)Our department is merging with another department. Both MS shops, but they are using the CRM to manage workflow internally, user roles, web forms and the back end sql. It seems at first glance, that it's a well thought out comprehensive system. So my question is this: How extensible is ms crm, and where does a dot net web app programmer 'attach' to the system? Could I interface my current web apps with the crm back end for example, and populate the crm mechanisem?
i want to create a centralised business or Service authendication architecture in .net. for example, we have a clients like c1, c2, c3, c4, ... etc. everybody logins seperatly as well as grouply. ie, if client "C1" logins [with login authentication] he can access c2 , c3, c4 also without login authendication. So its like a google. if we enters gmail account, we can access orkut, picasa like that.. i need the cetralised architecture.
And, client "c1" seperately asks seperately how will be the authendication architecture.
so give me the single solution for both these two scenarios. how will be the architecture for these two and how is the Data Base (Login) Structure.
recently i've studied on ADO.NET's Entity Model Framework and say 'wow' as ORM is one of the fevourite pattern i practice..but suddenly i've come to an ambiguous situation when i'm going to start. i usually follow the following 3-tier architecture..
1. UI Layer 2. BLL - business logic layer 3. DAL - Data Access Layer a. DTO / DAO b. Gateway (contains the sql query/stored procedure and connection with DB)
now when i'm going to use the Entity Model Design,where the DBML/ .edmx File should be placed? Because many a times i'm using the DBML file as DTO because of the mapped objects.. in the same time, sometimes DBML ( .edmx file in .NET 4.0) contains CRUD methods and stored procedured method as well as methods with different selection operations,- which should be in Gateway. so where the .edmx file should be placed !?!! IN DTO namespace !? or in Gateway namespace!
moreover sometimes there is no need for the BLL which breaks the rules of inter-layer-communication (UI > BLL > DAL.Gateway)! what makes me confuse is, what should be the ideal n-tier architecture when i'll use the ADO.NET Entity Model Design Framework
integrate payment gateway in my webapplication. I don't have any idea on that.I want to get the payment through debit card, credit card, internet banking too..
I need to run the HttpContext.Current.Server.Execute method in my ASP.NET application. This application has a WCF operation that does some processing. Currently, I am running a Server.Execute call from within my WCF operation and getting the results I would expect. However, I would like to do this asynchronously.This is where my problem comes in. In an error to run Server.Execute asynchronously, I tried running Server.Execute in the DoWork event handler of a BackgroundWorker. Unfortunately, this throws an error that says
"object reference not set to an instance of an object"
The HttpContext element is not null. I checked that. It is some property nested in the HttpContext object that appears to be null. However, I have not been able to identify why this won't work. It happens as soon as I move the processing to the BackgroundWorker thread. My question is, how can I asynchronously execute the Server.Execute method? Are there options beyond BackgroundWorker that will work?
I am a newbie to asp.net and work in a firm where the projects are quite small.
I was told by my manager that in a few weeks or so we would be getting a bigger project and I need to be well versed with Design Patterns and N tier arcihtecture.
I would really appreciate if someone could provide me some links and also drop me a few sentences on how this things are useful?
I am try to create architecture design for WCF service.
We have WCF service that we have to expose to third party so then can request with xml and get back xml response.
The wcf service should do the following:
- Accept the request call with xml
- Check xml against the schema
- Parse the xml
- Authenticate the incoming xml by username and password that will be in xml
- Send back the response
If anybody can let me know what kind of design I can use or is there any pattern available that I can take it and then extend it as per my requirement.
designing Business Objects. What a business object class can contain ?
I have looked many sample codes and articles. Some only use properties in them. Some use private members, properties and constructoers. As more I am reading becoming more confuse.
Some sample codes that I checked were making functions in BO classes as well. what a BO class should contain and what is its purpose. Should there be functions in them as well ? If yes how they can be differentiated from Business Logic class functions.
All the users of my system get a common Id (SystemUserId). There are predefined roles/groups in the system. One user can be belong one or more of these groups. We are populating the menu/dashboard at runtime according to logging credentials.All common details (properties) of group are stored in main table (SystemUser) and specialized details are stored in relavant tables.(Teacher/Student). My solution already has classes called, SystemUser, Teacher & Student.
Problem:My system should support new group addition. (eg-: Auditor)This should support new properties to be added to SystemUser/Teacher/Student or any other new group added by the Customer at runtime.
modules is being used for some sites when they are developing. what is this module. for example, this sites has some modules; membership module,comment module etc.Are modules a diffrent application that is added to site later, or they talk about httpmodules?
also, how can i begin this module design and coding?
suggest me a good design pattern for implmenting the following? I have an object say myObject. This myObject is created using few inputs from the UI. After the creation of myObject. This object will be passed to few methods.. like method1(myObject);
method2(myObject);... method5(myObject);etc. Each methods will prepare the input for successive methods call. For example method1(myObject) will set the values necessary for the operation of method2.Then method2(myObject) will set up the values necessary for the operation of method3 and so on..Same object is used as the argument for every method calls.Which design pattern can be implemented?
how to design following small webproject and database .i am totally new in this area.
I need to quickly develop a system so that everyone can access the status of the job going online into the system
Activities
Move the job between work centers when it's completed.
Transfer button. So when design is done we should be able to click the transfer button and move the job from Design to Procurement
Here are the work centers.
plan cerement TST Shipped Each work center should have due dates User will have to update manually due date for each work center and this will be different for each job.
I am thinking to use entity model as DAL, how should I create the BLL then? What kind of datasourceobject should I use in the asp pages?
I am looking for best practice to use Entity framework 2 in the three layers design. I had experience at dataset with three layers design.
Should I use objectdatasource at the pages for gridviews? My guess is that entitydatasource by passed the BLL which is not good, so the only option left is the objectdatasource.
Could and should my BL object inherit those entity model in the DAL, so I dont need to recreate their object's property?
I want to know what is the advantages of using aggregates in c# for design patterns.
suppose i have tree tables
Member(M_Id,M_Info)
Bid(B_Id,B_Info,M_Id,Item_Id)
Item(Item_Id,Item_Info)
"One member can place more than one bid on more than one item."
so there is one to many bidirectional association between Bid and Member table.
And one to many association between bid and item table Now According to defination of aggregates in this case Item table is the root of aggregate item and item has aggregation with bid table.
and bid table holds unidirectional reference to member table and hence only bid table has access over member table.
But ultimately this will also map in database same as without using aggregate then what is use of aggregates?
I visited this Link to study about Factory design pattern.http://wiki.asp.net/page.aspx/310/factory/ But i am confused about it still. What i understood is that we must use an Interface to define a class .In the interface we will give the prototype of functions and later on we will define it in concrete class. Is that simple concept is Factory design pattern ?
I have a ordinary Category/Product database relationship Design structure.
Now i wish to add a sub category to this architecture.
for example, Cloths Category needs to be sub divided - Women,Men,Children categories.Also what about other Ctegories such as: Car,this also has sub divisions: Model,Type.
My Products table contains ProductName field together with generic field for Size,Colour and Price fields.
How do you therefore incorporate this sub division into the existing Category/Product relationship model and is there a model example?
how a large ASP.NET webapplication can be structured / designed with "subwebs" !? In other words I want to structure a large web-application where I have a solution with more web-application projects. These projects are more or less independent "modules". One project should be a kind of frame application with shared masterpages, an shared sitemap and and a shared authentication. Later it should also be maybe possible also to integrate loosely older websites (which where written in classic ASP. ASP.NET 1.1, ASP.NET 2.0), but this not so important at the moment
I would like to provide my client with a aspx pages, with code behind provided, etc. But in some cases they will want to write their own markup - I'm thinking of having 2 directories [siblings of each other], one for the pages I provide, and the other for their custom markup. At page serve time, check to see if the client wrote their own markup and if so use it. Otherwise use the default provided.
In a nutshell I would like for my clients to be able to modify the pages I provide, but if they blow it up have a very easy way to back it out. Or to put it in a more positive light, allow them to override my pages easily.
