• Two different tables or just one with bool column?

  - by Aidas

  We have two tables: OriginalDocument and ProcessedDocument. In the first one we put an original, not processed document. After it's validated and processed (converted to our xml format and parsed), it's put into Document table. Processed document can be valid or invalid. Which makes more sense: have two different tables for valid and invalid documents or just have one with 'Valid' column? Some of the columns (~5-7) are irrelevant for invalid document. Storing both invalid and valid documents would also make Document table filled with 'NULL' columns (if document is invalid, information like document number, receiver can be unknown). What else should we consider and weigh, when making this decision?

• Data Modeling of Entity with Attributes

  - by StackOverflowNewbie

  I'm storing some very basic information "data sources" coming into my application. These data sources can be in the form of a document (e.g. PDF, etc.), audio (e.g. MP3, etc.) or video (e.g. AVI, etc.). Say, for example, I am only interested in the filename of the data source. Thus, I have the following table: DataSource Id (PK) Filename For each data source, I also need to store some of its attributes. Example for a PDF would be "numbe of pages." Example for audio would be "bit rate." Example for video would be "duration." Each DataSource will have different requirements for the attributes that need to be stored. So, I have modeled "data source attribute" this way: DataSourceAttribute Id (PK) DataSourceId (FK) Name Value Thus, I would have records like these: DataSource->Id = 1 DataSource->Filename = 'mydoc.pdf' DataSource->Id = 2 DataSource->Filename = 'mysong.mp3' DataSource->Id = 3 DataSource->Filename = 'myvideo.avi' DataSourceAttribute->Id = 1 DataSourceAttribute->DataSourceId = 1 DataSourceAttribute->Name = 'TotalPages' DataSourceAttribute->Value = '10' DataSourceAttribute->Id = 2 DataSourceAttribute->DataSourceId = 2 DataSourceAttribute->Name = 'BitRate' DataSourceAttribute->Value '16' DataSourceAttribute->Id = 3 DataSourceAttribute->DataSourceId = 3 DataSourceAttribute->Name = 'Duration' DataSourceAttribute->Value = '1:32' My problem is that this doesn't seem to scale. For example, say I need to query for all the PDF documents along with thier total number of pages: Filename, TotalPages 'mydoc.pdf', '10' 'myotherdoc.pdf', '23' ... The JOINs needed to produce the above result is just too costly. How should I address this problem?

• Tables as relations in ER diagrams

  - by Richard Mar.

  Assume I have the following tables (**bold** - primary key, *italics* - foreign key): patient(**patient_id**, name) disease(**disease_id**, name) patient_disease(**p_d_id**, *patient_id*, *disease,_id* ) I want to draw the ER diagram for this. My idea is to make two entities, one for patient and one for disease, then make a n-to-n relation between them, with p_d_id as its attribute. Is that how it's supposed to be?

• How can I connect to a CIFS/SMB share on a non-default port?

  - by fsckin

  I'm trying to get a contractor connected to a CIFS share (port 445). He's not a big shop (so no go on using VPN). His ISP blocks outgoing connections on port 445. I've been doing some rsync to ftp madness as a workaround to have the share available to him, but it's getting out of control -- we're syncing nearly 40GB a day to an external ftp site and it's going to be much easier just to have him connect and only grab the stuff he needs. So... I can have the CIFS share open to the internet (filtered to allow access to his IP only) on port 446. How the heck can he connect to that? I looked through "net use" and didn't see anything about using another port.

• Active Directory: Viewing "Attribute Editor" after finding an account via ADUC's "Find" option

  - by Beaming Mel-Bin

  When I activate the Advanced features (View - Advanced Features) and open a user's properties by navigating to their OU and right clicking the user object, I see the Attribute Editor tab. However, if I search for a user (right click the domain - Find - search for the user), and double click on the user, I do not see the tab. I cannot normally navigate to users because some OUs have too many users. Can someone suggest an alternative that allows me to view the Attribute Editor tab?

• Distributing WPF apps to a legacy user base: How seamless is it?

  - by Christian Nunciato

  I'm considering developing a WPF application, to be hosted by a legacy Windows app (C++), and I'm trying to get a better sense of how feasible it'll be to do so, given the broad user base I'm targeting. Knowing WPF targets .NET 3.5, I'm looking for some insight as to what the field looks like right now -- who's already got the runtime, whether it's distributed by Windows Update, if so, how (e.g., as an optional or required download, to which operating systems, etc.), whether XP pre-XP2 supports it (and how), and so on. The current version's got many thousands of users, using all manner of Windows operating systems, and while I'd very much like to leverage WPF to breathe some life into their user experience, I want to make sure I'm not shutting anyone out by doing so, or burdening them with a download they might have to do manually. I realize most, or all, of this information's out there already, in various places, but I figured I'd ask here first, since I'm sure some of you've probably already gone down this road and have valuable experiences to share. Thanks in advance!

• Cross-forest GPO between 2003 and 2008 Denied Beacuse it's "Inaccessible"

  - by j.rightly

  I have a two-way, non-transitive trust between two forests and domains, "W2003" and "W2008". In W2008 I have a GPO with user settings linked to a machine OU containing machine "Server". The GPO applies to Authenticated Users. Cross-forest loopback processing is enabled in merge mode. When I log onto Server as User (whose account exists in the W2003 domain), the GPO does not apply. I run RSoP and see that the GPO is "Denied" for the reason "Inaccessible." The GPO name is not listed, but the GUID is. I have checked the file-level permissions on the DC to ensure that User has access to read the GPO's folder and all its contents. What is going on?

• Can storage-spaces drives be moved to a replacement server when there is a failure

  - by Joe C

  I have tried to search here and Google, but cannot find a case explaining this. Storage spaces is similar to software raid. If the server fails due to motherboard or some other issue, can the drives that comprise that storage spaces config be moved to another win2k12 server without restoring from backup? This can be done in linux software raid. If so, does the storage space config have to be re-created prior to the move, or do the drives hold the config so they are essentially plug and play? Thanks.

• Dynamic DNS registration for VPN clients

  - by Eric Falsken

  I've got a VPN server set up in my Active Directory on a remote network. (VPN Server is separate box from DNS/AD) When I dial into the network (client machine is not a member of the AD) the machine does not register its IP or Hostname in the DNS. I've played with all possible combinations of DHCP and RRAS-allocated IP pools, and none of them seem to cause my client to register. Is it because my client has to be a member of the domain? Are there some security settins I can tweak so that it can register its hostname/ip? I've looked in the event logs (System and Security) for the AD, DNS, DHCP, RRAS, and the client machine, and don't see anything relating to DNS Registration. Here's the IPConfig on the client machine (once connected): PPP adapter My VPN Name: Connection-specific DNS Suffix . : mydomain.local Description . . . . . . . . . . . : My VPN Name Physical Address. . . . . . . . . : DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 192.168.1.22(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : DNS Servers . . . . . . . . . . . : 192.168.1.52 <- DC1 192.168.1.53 <- DC2 NetBIOS over Tcpip. . . . . . . . : Enabled

• What is an index in MySQL?

  - by Eric

  http://i.imgur.com/JdsUK.jpg I created a table like the picture above. What are the "Indexes"? primary key? unique? It works well without setting indexes.. What do they do? why do I need them? Also, I set all String fields to TEXT because I didn't know how many characters I need. Is this a good idea? I don't see any difference. Thanks!

• Can't double click files to open them in inDesign (CS5)

  - by Matt

  I cannot open a file unless I open inDesign (the program) and then do File-Open If I double click, it starts to open, then just hangs forever. AFTER I close it, and look in the directory where they're saved, I see a (temporary?) "lock" file. Now I can double click the original file and it opens just fine. However, now when I close iD it deletes the file and the whole process starts again... I have tried updating the software, uninstalled COMPLETELY and reinstalled, tried a brand new Win7 install. These files are all saved on a network drive, the computer is a new quad-core Dell with 12GB of RAM and a fresh x64 Win7 install on the SSD. Does not happen with other programs.

• How to force grails GORM to respect DB scheme ?

  - by fabien-barbier

  I have two domains : class CodeSet { String id String owner String comments String geneRLF String systemAPF static hasMany = [cartridges:Cartridge] static constraints = { id(unique:true,blank:false) } static mapping = { table 'code_set' version false columns { id column:'code_set_id', generator: 'assigned' owner column:'owner' comments column:'comments' geneRLF column:'gene_rlf' systemAPF column:'system_apf' } } and : class Cartridge { String id String code_set_id Date runDate static belongsTo = CodeSet static constraints = { id(unique:true,blank:false) } static mapping = { table 'cartridge' version false columns { id column:'cartridge_id', generator: 'assigned' code_set_id column:'code_set_id' runDate column:'run_date' } } Actually, with those models, I get tables : - code_set, - cartridge, - and table : code_set_cartridge (two fields : code_set_cartridges_id, cartridge_id) I would like to not have code_set_cartridge table, but keep relationship : code_set -- 1:n -- cartridge In other words, how can I keep association between code_set and cartridge without intermediate table ? (using code_set_id as primary key in code_set and code_set_id as foreign key in cartridge). Mapping with GORM can be done without intermediate table?

• Common one-to-many table for multiple entities

  - by Ben V

  Suppose I have two tables, Customer and Vendor. I want to have a common address table for customer and vendor addresses. Customers and Vendors can both have one to many addresses. Option 1 Add columns for the AddressID to the Customer and Vendor tables. This just doesn't seem like a clean solution to me. Customer Vendor Address -------- --------- --------- CustomerID VendorID AddressID AddressID1 AddressID1 Street AddressID2 AddressID2 City... Option 2 Move the foreign key to the Address table. For a Customer, Address.CustomerID will be populated. For a Vendor, Address.VendorID will be populated. I don't like this either - I shouldn't need to modify the address table every time I want to use it for another entity. Customer Vendor Address -------- --------- --------- CustomerID VendorID AddressID CustomerID VendorID Option 3 I've also seen this - only 1 foreign key column on the Address table with another column to identify which foreign key table the address belongs to. I don't like this one because it requires all the foreign key tables to have the same type of ID. It also seems messy once you start coding against it. Customer Vendor Address -------- --------- --------- CustomerID VendorID AddressID FKTable FKID So, am I just too picky, or is there something I haven't thought of?

• Symantec Gateway Security 320 VPN/Port Forwarding trouble

  How do I check to see if port forward is enabled with one of my dynamic tunnels on this device? I'm having trouble using a feature in our software that requires a vpn to be used. My firewalls shows it as connected but I'm unable to ping the subnet ip. Our software vendor told me that port forwarding might be causing this problem, but I didn't set up this network I'm on and I don't fully know symantec hardware.
