  • Is Domain Driven Design useful / productive for not so complex domains?

    - by Elijah
    When assessing a potential project at work, I suggested that it might be advantageous to use a domain driven design approach to its object model. The project does not have an excessively complex domain, so my coworker threw this at me: It has been said, that DDD is favorable in instances where there is a complex domain model (“...It applies whenever we are operating in a complex, intricate domain” Eric Evans). What I'm lost on is - how you define the complexity of a domain? Can it be defined by the number of aggregate roots in the domain model? Is the complexity of a domain in the interaction of objects? The domain that we are assessing is related online publishing and content management.

  • Alternative to GoDaddy's ConsoliDate feature (change domain expiration date)

    - by Jim
    I've been using GoDaddy to manage about 50 domain names for a few years, but recently decided to move (probably to namecheap) because of the elephant killing incident. One GoDaddy's feature I like a lot is Consolidate, which allows you to change the expiration date of domain names for a small fee. I've searched for a while but didn't find any other registrar that provides this feature. Does anyone know if there's a registrar that allows you to change the expiration date of domains? Thanks!

  • Challenge a .name registration?

    - by Shtééf
    The Wikipedia page on .name says the following: Registration restrictions: No prior restriction on registration, but registrations can be challenged if not by or on behalf of individual with name similar to that of domain, or fictional character in which registrant has rights But there's no further info on how this actually works. Can a .name domain registration be challenged, and if so, how?

  • MS DPM 2007: Testing the Recovery for a Production Domain

    - by NewToDPM
    Hi everybody! MS DPM 2007 is a new technology in my company, and so am I to the product. We have a classic Microsoft domain with two DCs, Exchange 2007 and a couple Web/MS SQL servers. I have deployed DPM one month ago on the domain, and after fixing the various issues I got with the replicas inconsistence and adapting the schedule and retention range to the server storage pool size, I can say the backup system is working correctly (no errors) as of today. However, there is one problem: we did not attempt to restore from the backups yet, which is a big no-no of course. I'm not sure about the way I should handle this, my main concern being Exchange and the System State of the DCs. From my understanding, DPM can only protect AND restore data on a server which is part of the same domain as the backup server. If I restore the System State (containing Active Directory) and the Exchange Storage Groups on a testing server, I am afraid it would completely disturb the domain functioning (for example, having two primary DCs on the domain). I am thinking about building a second DPM server on a testing separate domain which would mirror the replicas and then restore it on testing servers from this new domain. Is it the right way to handle the data recovery testing? How did you do on your domain when you first deployed DPM? I'd be grateful for any link/documentation or advice. Thank you in advance for your help! EDIT: Two options seem possible so far: i. Create another DC/Exchange server in the alternate location; ii. Create a separate domain in the alternate location and setup a trust between this domain and the production one. The option i is certainly the best but implies setting up a secondary Exchange server, with a dedicated public IP address so that if Exchange #1 dies, we can still send emails with Exchange #2. I don't know how complex this can be and would need to discuss it with my colleagues. The option ii would only fit the testing purposes. My only question regarding this is: if my production and DPM servers are part of domain A, and there is a trust between domains A and B, can I restore a domain A content to any domain B server?

  • Trying to configure DNS on a Godaddy Virtual Dedicated host, Mediatemple Domain Registration

    - by dclowd9901
    A client of mine purchased VD hosting with Godaddy and a domain name with Mediatemple. I've never configured DNS from scratch, and I'm finding it very difficult to find any sort of explanation on how to go about it. As of right now, Mediatemple is pointing to the Godaddy's ns1.domaincontrol.com and ns2.domaincontrol.com nameservers. The VD hosting on Godaddy (via their Simple Control Panel) has options to "Add a new domain", which brings you through a wizard of sorts that asks you if the domain has already been registered (yes), what it is (dclowd9901.com for this example), create a system username and password for it (with checkboxes for SSH and FTP access), which level of user can administer it, and whether a mail account should be setup. When complete, it also creates a zone file. In this zone file, the Primary nameserver is ns1.dclowd9901.com; the records are as follow (where 12.23.12.34 is the presumed host): @ A 12.23.12.34 @ NS ns1 @ NS ns2 ns1 A 12.23.12.34 ns2 A 12.23.12.34 @ MX mail www A 12.23.12.34 ftp A 12.23.12.34 ssh A 12.23.12.34 mail A 12.23.12.34 If anyone can shed any light on this for me, explain to me the interactions between the registrar and the host and so on, I'd be very grateful. Thanks in advance for the help.

  • Sample domain model for online store

    - by Carel
    We are a group of 4 software development students currently studying at the Cape Peninsula University of Technology. Currently, we are tasked with developing a web application that functions as a online store. We decided to do the back-end in Java while making use of Google Guice for persistence(which is mostly irrelevant for my question). The general idea so far to use PHP to create the website. We decided that we would like to try, after handing in the project, and register a business to actually implement the website. The problem we have been experiencing is with the domain model. These are mostly small issues, however they are starting to impact the schedule of our project. Since we are all young IT students, we have virtually no experience in the business world. As such, we spend quite a significant amount of time planning the domain model in the first place. Now, some of the issues we're picking up is say the reference between the Customer entity and the order entity. Currently, we don't have the customer id in the order entity and we have a list of order entities in the customer entity. Lately, I have wondered if the persistence mechanism will put the client id physically in the order table, even if it's not in the entity? So, I started wondering, if you load a customer object, it will search the entire order table for orders with the customer's id. Now, say you have 10 000 customers and 500 000 orders, won't this take an extremely long time? There are also some business processes that I'm not completely clear on. Finally, my question is: does anyone know of a sample domain model out there that is similar to what we're trying to achieve that will be safe to look at as a reference? I don't want to be accused of stealing anybody's intellectual property, especially since we might implement this as a business.

  • Anemic Domain Model, Business Logic and DataMapper (PHP)

    - by sunwukung
    I've implemented a rudimentary ORM layer based on DataMapper (I don't want to use a full blown ORM like Propel/Doctrine - for anything beyond simple fetch/save ops I prefer to access the data directly layer using a SQL abstraction layer). Following the DataMapper pattern, I've endeavoured to keep all persistence operations in the Mapper - including the location of related entities. My Entities have access to their Mapper, although I try not to call Mapper logic from the Entity interface (although this would be simple enough). The result is: // get a mapper and produce an entity $ProductMapper = $di->get('product_mapper'); $Product = $ProductMapper->find('[email protected]','email'); //.. mutaute some values.. save $ProductMapper->save($Product) // uses __get to trigger relation acquisition $Manufacturer = $Product->manufacturer; I've read some articles regarding the concept of an Anemic Domain model, i.e. a Model that does not contain any "business logic". When demonstrating the sort of business logic ideally suited to a Domain Model, however, acquiring related data items is a common example. Therefore I wanted to ask this question: Is persistence logic appropriate in Domain Model objects?

  • Keeping a domain model consistent with actual data

    - by fstuijt
    Recently domain driven design got my attention, and while thinking about how this approach could help us I came across the following problem. In DDD the common approach is to retrieve entities (or better, aggregate roots) from a repository which acts as a in-memory collection of these entities. After these entities have been retrieved, they can be updated or deleted by the user, however after retrieval they are essentially disconnected from the data source and one must actively inform the repository to update the data source and make is consistent again with our in-memory representation. What is the DDD approach to retrieving entities that should remain connected to the data source? For example, in our situation we retrieve a series of sensors that have a specific measurement during retrieval. Over time, these measurement values may change and our business logic in the domain model should respond to these changes properly. E.g., domain events may be raised if a sensor value exceeds a predefined threshold. However, using the repository approach, these sensor values are just snapshots, and are disconnected from the data source. Does any of you have an idea on how to solve this following the DDD approach?

  • Where we should put validation for domain model

    - by adisembiring
    I still looking best practice for domain model validation. Is that good to put the validation in constructor of domain model ? my domain model validation example as follows: public class Order { private readonly List<OrderLine> _lineItems; public virtual Customer Customer { get; private set; } public virtual DateTime OrderDate { get; private set; } public virtual decimal OrderTotal { get; private set; } public Order (Customer customer) { if (customer == null) throw new ArgumentException("Customer name must be defined"); Customer = customer; OrderDate = DateTime.Now; _lineItems = new List<LineItem>(); } public void AddOderLine //.... public IEnumerable<OrderLine> AddOderLine { get {return _lineItems;} } } public class OrderLine { public virtual Order Order { get; set; } public virtual Product Product { get; set; } public virtual int Quantity { get; set; } public virtual decimal UnitPrice { get; set; } public OrderLine(Order order, int quantity, Product product) { if (order == null) throw new ArgumentException("Order name must be defined"); if (quantity <= 0) throw new ArgumentException("Quantity must be greater than zero"); if (product == null) throw new ArgumentException("Product name must be defined"); Order = order; Quantity = quantity; Product = product; } } Thanks for all of your suggestion.

  • dns hosting - url forwarding - hiding forwarded url?

    - by jeremycollins
    I have free dns hosting with the domain registrar and I'd like the dns hosted domain www.example.com to display contents of www.myotherlongdomain.com. I only have 301/302/iframe forwarding options, however I want to mask the redirected (longdomain) url. If I use frames, users can view the source and see the (longdomain) url the contents are coming from. How can I hide it so it always displays www.example.com? There is no cloaking/masking option with the registrar. Thanks.

  • Forwarding non-www domain to other domain with dns

    - by Zen Savona
    Is it possible to forward firstdomain.com to www.seconddomain.com or seconddomain.com using surely dns records? I know how to forward www.firstdomain.com to seconddomain.com (with CNAME). What I am trying to do is move my site from one domain to another (new) one, and not break all the links which use the old domain name. I can't do a 301 redirect as it's hosted on Github Pages and I don't have access to the webserver. Thanks

  • I am transferring a namserver domain what do I need to update?

    - by Mech Software
    Perhaps I am totally over thinking this but I have a domain name and name servers that are working just fine. I want to transfer the one domain name that I have for my server which is also the name of the nameserver. e.g. mydomain.com with nameservers ns1.mydomain.com ns2.mydomain.com I am transfering the mydomain.com from the current registrar to the one I use for all my other domains. The question is what do I have to update? Once the transfer is complete mydomain.com will have ns1.mydomain.com and ns2.mydomain.com as it's nameservers as it is today. I was wondering though how ns1.mydomain.com and ns2.mydomain.com are resolving if mydomain.com is pointing to ns1 and ns2. Am I over thinking this or am I missing something in the process here? I always just enter the nameserver names when I configure any domains on my server. Do I have to setup A records somewhere for ns1 and ns2 ?

  • Is domain-transfer inherently safe for downtime when the name servers remain the same?

    - by jlmt
    I've been reading around this topic towards understanding whether there's some or no chance of downtime during an upcoming domain transfer for 15 live and very critical domains. In our case there are three companies involved: CompanyA is the original registrar and DNS host, CompanyB is the new DNS host, and CompanyC is the new registrar. I've already changed the nameservers for all domains to those of CompanyB. We suffered some downtime because CompanyA deleted their hosted DNS for our domains directly after the change, but the changes propagated and we're now able to configure our DNS with CompanyB. From what I understand (please correct where wrong!): There exists an SOA record that points oneofourdomains.com to ns.companyb.com. That record is maintained and authoritatively hosted by the ccTLD registry for the domain (eg. Verisign for .com). CompanyA currently has the ability to change the SOA record because they're the registrar. There exist NS records for oneofourdomains.com, which are also related to the link from domain name to nameserver, are similarly hosted by the ccTLD, and which CompanyA are also able to change while acting as registrar. Neither CompanyB nor CompanyC currently have any control over the SOA or NS records. CompanyA are unable to cause us (DNS) problems during the transfer by dropping service early, because they are not the authoritative source for the SOA and NS records. When we transfer the domains, it's administrative control of the SOA and NS records that will be transferred to CompanyC. As long as we advise CompanyC that the SOA and NS records must not change (as regards pointing to CompanyB's nameservers), there's no need for any kind of DNS change, and therefore no possibility of downtime. Is my understanding of this correct? My fear is that CompanyA will somehow cut us off again, and their support dept hasn't given me much confidence in their understanding of the topic.

  • Cannot create a new domain in an existing active directory forest

    - by Mackenzie Carr
    I have a domain controller setup on Windows Server 2008 R2 (Forest) and I have another Windows Server 2008 R2 (New Domain) and I want to create a new domain in an existing forest. I get the following error: An Active Directory domain controller for the domain mackdev.mackenziecarr.com could not be contacted The error was "no records found for the given DNS query" The query was for the SRV record for: _ldap._tcp.dc._msdcs.mackdev.mackenziecarr.com I've seem to have tried everything even tried adding this record to the DNS server of the primary forest. I even successfully joined this server to the domain without any issues but trying to create a new domain under the existing forest is no luck. The primary forest I.P. address is 192.168.2.20 the server that I am using to try to make a child domain is 192.168.2.21 My ipconfig are as follows: I.P. Address: 192.168.2.21 Subnetmask: 255.255.255.0 Gateway: 192.168.2.1 Primary DNS: 192.168.2.20

  • Using "Active Directory Users and Computers" for a different domain

    - by Jaxidian
    How can I manage a domain with the "Active Directory Users and Computers" from a computer that is not on that domain? I realize I'll need some domain admin (or less) credentials, but that's fine. I have 2 scenarios where I'd like to do this: From a machine on Domain 1 but I'd also like to manage Domain 2 (the 2 domains are in no way related) From a laptop that is not a member of any domain. If we can figure out #2, that will be "good enough" but #1 would be nice too.

  • apache domain redirect to subfolder

    - by Dennis
    I have a hosting account with godaddy. Its a linux system running apache. The way they do their setup is your primary domain is the root folder. When you add a subdomain its in a subfolder of the root which sucks. I want to setup a subfolder structure to organize my domains.. I called godday support and they said to use redirects.. but did not know how to do that.. How its setup now: primary domain: www.domain.com / sub.domain.com /sub I want to create a directory structure and then redirect to each but only show www.domain.com in the url www.domain.com /domain/www sub.domain.com /domain/sub I tried using: RewriteEngine On RewriteCond %{HTTP_HOST} ^(www.)?domain.com$ RewriteRule ^(/)?$ domain/www [L] but it just changes the url to www.domain.com/domain/www Can this be done in htaccess?

  • Domain registration public information, measures domain authority in SEO?

    - by Rana
    I have seen on internet in various places talking about this and they says this information do have impact on SEO, specially in the domain authority section. Is it so? If so, Is there any proper way to fill this up? Like, I am running a site as my blog, what should the the organization field? If I own multiple domains, will having same contact information on all of them help gain domain authority? As a owner of multiple sites, should organization name be same or different? Considering I don't own a company yet? Any other suggestion about this?

  • Domain forwarding (GoDaddy) - Forward only / Forward with masking

    - by jan
    I am trying to configure my domain to forward to my app engine application. For the forwarding I can choose from "forward only" and "forward with masking". Assume my domain is called "myDomain.com" and my app is located at myApp.appspot.com. If I choose "forward only" and I go to myDomain.com, I get redirect to myApp.appspot.com (myApp.appspot.com also showing in the address bar - But I want to show myDomain.com of course). If I choose "forward with masking", "myDomain.com" is always shown in the address bar, even if I navigate to some subpage. The URL then should look like e.g.: "myDomain.com#!page:xyz", but still shows "myDomain.com". Is there some way in the middle?

  • How to enable customers to use their own domain for sites hosted by me

    - by Scott
    I am thinking of running a self-site builder. But was wondering how would I allow customers to use their own domains that they already own. Is that even possible? Let's say my site is www.bestsitebuildingwebsite.com and each customer has urls like this www.bestsitebuildingwebsite.com/frances www.bestsitebuildingwebsite.com/eden www.bestsitebuildingwebsite.com/john And a customer has a domain called widgets.com Is it actually possible domain widgets.com to go to my site somehow and have HASHES on the URL still work (my site makes use of hashes for AJAX queries). And their site still have good SEO with Google? Thanks Scott

  • New domain and submission to search engines

    - by Guandalino
    I have registered a new domain with a hosting company. They offer the feature that for each new domain there is an associated placeholder page. Actually it is a "Site not configured page" with some technical text and links to the hosting site. I could: submit its URL to search engines right now remove the page and submit the URL when the site will be online (could be a couple of months) replace the default page with "coming soon" contents and submit the URL opt for simplicity and add a blank html page having a focused and well descriptive title and maybe some meta tag other? I prefer 4 over 3 because at the moment there aren't precise project details to provide. What's the proper way to notify search engines that soon this site will be online, without getting penalized for side effects I'm not considering or aware of?
