  • Data Governance (Veri Yönetisimi)

    - by Arda Eralp
    Data governance,veri ile ilgili islemler için bir sorumluluklar sistemidir. Bu sistemin temelini ise politikalar, standartlar ve prosedürler olusturur. Sistem politikalar, standartlar ve prosedürler sayesinde verinin ne zaman, hangi sartlar altinda, hangi eylemlerde, hangi yöntemler ile kimler tarafindan kullanilacagina karar verir. Sistemin kurumda basarili bir sekilde islemesi için öncelikle kurumda farkindalik saglanmasi gereklidir. Farkindalik saglandiktan sonra ise kurum governance ve mimari kültürünü benimsemelidir. Ancak bu sartlar altinda sistem basarili bir sekilde isleyebilecektir. Bu sebeplerden dolayidir ki data governance kisa bir süreç degil, aksine kurum varligini sürdürdügü sürece isleyecek olan bir süreçtir. Bu durum bize data governance in bir proje degil bir program oldugunu açiklamaktadir. Programin baslangicinda kurumun ihtiyaçlarinin netlesmesi ve farkindaligin saglanmasi temeldir. Hedef kitle ise, veri ile dogrudan ve ya dolayli olarak iliski içerisinde olan herkesdir. Bu sebeple programin baslangicinda hedef kitleyi içeren ekipler ile toplantilar düzenlenecektir. Bu toplantilar sayesinde hem farkindalik saglanacak hemde ekiplerin ihtiyaçlari birebir ekipler tarafindan aktarilarak netlesecektir. Hedef kitlenin ihtiyaçlari netlestirildikten sonra ise devamli isleyecek olan bu sürecin planlamasi yapilacaktir. Bu sürecin planlanmasinda ihtiyaçlarin önceliklendirilmesi gerekmektedir. Sebebi ise her ekibin ihtiyaçlarinin farkli olabilecegi ve bütün ihtiyaçlara ayni anda karsilik verilemeyebileceginin öngörülmesidir. Bu öngörünün temeli ise ekiplerin ihtiyaçlarinin birbirleriyle olan baglantisidir. Süreç planlamasinda ihtiyaçlarin önceliklendirilmesinin ardindan kurumun büyüklügünün gözönünde bulundurulmasi gerekmedir. Kurumun büyüklügünün önemi ise eger kurum bir bütün olarak ayni anda govern edilemeyecek kadar büyük ise ihtiyaçlari öncelikli olarak bulunan ekipler ile govern edilmesine baslanarak sürecin belirli bir hiz ile bütün kurumda isler hale getirilmesini saglamaktir. Ihtiyaçlar belirlendikten ve ilgili ekipler seçildikten sonra artik programin planlanmasina geçilebilecek. Programin planlama asamasinda öncelikli olarak sürecin asamalarini kontrol edecek ve süreç kurum içerisinde isleyise geçtiginde kontrolü saglayacak olan Data Governance Office in planlanmasidir. Office in planlanmasiyla birlikte süreçteki roller ve bu rollerin sorumluluklari belirlenecektir. Planlama asamasinda Data governance office, roller ve sorumluluklar, güvenlik ve veri saklanan sistemler ele alinacak konulardir. Planlama asamasi tamamlandiginda ise belirlenen ekipler ve ihtiyaçlar dogrultusunda programin isleyis asamasina geçilebilecektir. Isleyis kisminda ekibin ihtiyaçlari dogrultusunda güvenlik konusunda ve veri saklanan sistemler üzerinde çalismalar yapilacaktir. Bu yapilan çalismalar bir süreç olarak dökümante edilecek ve süreç sona erdiginde baska bir ekiple baska bir ihtiyaç dogrultusunda çalisma yapilarak ayni süreç isletilecek ve böylece kurum içesinde ilgili süreçte standartlasma saglanacaktir. Güvenlik konusunda verinin erisim güvenligi ve kullanim güvenligi ele alinacaktir. Veri saklanan sistemler üzerindeki çalismalar ise saklanan sistemlerin program dahilinde belirlenen standartlar ile olusturulmasi ve yönetilmesi saglanacaktir. Isleyis kisminin ardindan ise programin izleme kismina geçilecektir. Bu kisimda artik Data Governance Office olusmus, politikalar, standartlar ve prosedürler belirlenmistir. Ve Data Governance Office çalisanlari rolleri ve sorumluluklari dahilinde programin isleyisini izleyecek ve gerek gördügünde politikalar standartlar ve prosedürler üzerinde degisiklikler yapacaklardir.

  • SQL 2014 does data the way developers want

    - by Rob Farley
    A post I’ve been meaning to write for a while, good that it fits with this month’s T-SQL Tuesday, hosted by Joey D’Antoni (@jdanton) Ever since I got into databases, I’ve been a fan. I studied Pure Maths at university (as well as Computer Science), and am very comfortable with Set Theory, which undergirds relational database concepts. But I’ve also spent a long time as a developer, and appreciate that that databases don’t exactly fit within the stuff I learned in my first year of uni, particularly the “Algorithms and Data Structures” subject, in which we studied concepts like linked lists. Writing in languages like C, we used pointers to quickly move around data, without a database in sight. Of course, if we had a power failure all this data was lost, as it was only persisted in RAM. Perhaps it’s why I’m a fan of database internals, of indexes, latches, execution plans, and so on – the developer in me wants to be reassured that we’re getting to the data as efficiently as possible. Back when SQL Server 2005 was approaching, one of the big stories was around CLR. Many were saying that T-SQL stored procedures would be a thing of the past because we now had CLR, and that obviously going to be much faster than using the abstracted T-SQL. Around the same time, we were seeing technologies like Linq-to-SQL produce poor T-SQL equivalents, and developers had had a gutful. They wanted to move away from T-SQL, having lost trust in it. I was never one of those developers, because I’d looked under the covers and knew that despite being abstracted, T-SQL was still a good way of getting to data. It worked for me, appealing to both my Set Theory side and my Developer side. CLR hasn’t exactly become the default option for stored procedures, although there are plenty of situations where it can be useful for getting faster performance. SQL Server 2014 is different though, through Hekaton – its In-Memory OLTP environment. When you create a table using Hekaton (that is, a memory-optimized one), the table you create is the kind of thing you’d’ve made as a developer. It creates code in C leveraging structs and pointers and arrays, which it compiles into fast code. When you insert data into it, it creates a new instance of a struct in memory, and adds it to an array. When the insert is committed, a small write is made to the transaction to make sure it’s durable, but none of the locking and latching behaviour that typifies transactional systems is needed. Indexes are done using hashes and using bw-trees (which avoid locking through the use of pointers) and by handling each updates as a delete-and-insert. This is data the way that developers do it when they’re coding for performance – the way I was taught at university before I learned about databases. Being done in C, it compiles to very quick code, and although these tables don’t support every feature that regular SQL tables do, this is still an excellent direction that has been taken. @rob_farley

  • Strategy for avoiding duplicate object ids for data shared across devices using iCloud

    - by rmaddy
    I have a data intensive iOS app that is not using CoreData nor does it support iCloud synching (yet). All of my objects are created with unique keys. I use a simple long long initialized with the current time. Then as I need a new key I increment the value by 1. This has all worked well for a few years with the app running isolated on a single device. Now I want to add support for automatic data sync across devices using iCloud. As my app is written, there is the possibility that two objects created on two different devices could end up with the same key. I need to avoid this possibility. I'm looking for ideas for solving this issue. I have a few requirements that the solution must meet: 1) The key needs to remain a single integral data type. Converting all existing keys to a compound key or to a string or other type would affect the entire code base and likely result in more bugs than it's worth. 2) The solution can't depend on an Internet connection. A user must be able to run the app and add data even with no Internet connection. The data should still resolve properly later when the data syncs through iCloud once a connection is available. I'll accept one exception to this rule. If no other option is available, I may be open to requiring an Internet connection the first time the app's data is initialized. One idea I have been toying around with in my head is logically splitting the integer key into two parts. The high 4 or 5 bits could be used as some sort of device id while the rest represents the actual key. The fuzzy part is figuring out how to come up with non-conflicting device ids that fit in a few bits. This should be viable since I don't need to deal will millions of devices. I just need to deal with the few devices that would be shared by a given iCloud account. I'm open to suggestions. Thanks.

  • How should game objects with fixed positions in the world be positioned?

    - by mars
    I have some game objects that are always at the same position in my game world as they make up some of the scenery of my puzzle game. At the moment, their positions are sort of hard coded in and some of their positions are calculated relative to the hard coded positions of other objects at the time of game initialization. This has been hard to maintain because whenever I've decided to change the position of these scenery objects as the game design evolved, I have to go and rewrite parts of the code that place the created objects and calculate their positions in the world. Is there a more maintainable way of handling the positioning of fixed game objects?

  • Why is BIND giving me a SERVFAIL in this case? (Notes inside)

    - by imaginative
    Woke up this morning to a bunch of the following: root@foo:/etc/bind# dig @1.2.3.4 foo.example.com ; <<>> DiG 9.6.1-P2 <<>> @1.2.3.4 foo.example.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 36121 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;;foo.example.com. IN A ;; Query time: 0 msec ;; SERVER: 1.2.3.4#53(1.2.3.4) ;; WHEN: Thu Apr 1 09:57:59 2010 ;; MSG SIZE rcvd: 31 Some background on the fictitious "1.2.3.4". It's a slave name server in my nameserver "farm". Technically I have ns1 (being the master) and ns2/ns3. Currently ns1/ns2 are down for maintenance, so I left ns3 at it serving live traffic. That's the point, DNS is supposed to be resilient. Now the odd part is, "1.2.3.4" was serving requests for example.com just fine for the last 4-5 days. This morning I get a phone call that it's non-responsive. After investigation I see the message you see above, SERVFAIL. I looked into the zone file and saw the following: example.com IN SOA ns1.example.com. hostmaster.mail.example.com. ( I wondered if at this point that the nameserver thought it was not authoritative over example.com and adjusted it to the following: example.com IN SOA ns3.example.com. hostmaster.mail.example.com. ( After that, it started responding again for all authoritative queries for example.com. I have no idea why. I thought these things were supposed to be normalized upon zone transfer from ns1 - ns3? Can someone please example why this happened and how to prevent it from happening in the future? I've never had a similar problem, and because I don't understand it well, I might be missing some critical information in this question. So please let me know if I can further add any detail to make things clearer as well. One more thing to note: I have other domains that I'm authoritative for that have their SOA still saying ns1.example.com. and not ns3.example.com. Those domains are serving requests just fine! Is it a matter of time before they stop also and I have to change SOA to ns3.example.com? Is this also only required because ns1 and ns2 are currently offline?

  • JGoodies HashMap

    - by JohnMcClane
    Hi, I'm trying to build a chart program using presentation model. Using JGoodies for data binding was relatively easy for simple types like strings or numbers. But I can't figure out how to use it on a hashmap. I'll try to explain how the chart works and what my problem is: A chart consists of DataSeries, a DataSeries consists of DataPoints. I want to have a data model and to be able to use different views on the same model (e.g. bar chart, pie chart,...). Each of them consists of three classes. For example: DataPointModel: holds the data model (value, label, category) DataPointViewModel: extends JGoodies PresentationModel. wraps around DataPointModel and holds view properties like font and color. DataPoint: abstract class, extends JComponent. Different Views must subclass and implement their own ui. Binding and creating the data model was easy, but i don't know how to bind my data series model. package at.onscreen.chart; import java.beans.PropertyChangeListener; import java.beans.PropertyChangeSupport;

  • Using Word COM objects in .NET, WinWord process won't quit after calling Word.Documents.Add

    - by Keith
    I'm running into the classic scenario where, when creating Word COM objects in .NET (via the Microsoft.Office.Interop.Word assembly), the WinWord process won't exit even though I'm properly closing and releasing the objects. I've narrowed it down to the use of the Word.Documents.Add() method. I can work with Word in other ways without a problem (opening documents, modifying contents, etc) and WinWord.exe quits when I tell it to. It's once I use the Add() method that the process is left running. Here is a simple example which reproduces the problem: Dim oWord As New Word.Application() oWord.Visible = False Dim oDocuments As Word.Documents = oWord.Documents Dim oDoc As Word.Document = oDocuments.Add(Template:=CObj(sTemplatePath), NewTemplate:=False, DocumentType:=Word.WdNewDocumentType.wdNewBlankDocument, Visible:=False) ' dispose objects oDoc.Close() While (Marshal.ReleaseComObject(oDoc) < 0) End While oDoc = Nothing oWord.Quit() While (Marshal.ReleaseComObject(oWord) < 0) End While oWord = Nothing As you can see I'm creating and disposing the objects properly, even taking the extra step to loop Marsha.ReleaseComObject until it returns the proper code. Working with the Word objects is fine in other regards, it's just that pesky Documents.Add that is causing me grief. Is there another object that gets created in this process that I need to reference and dispose of? Is there another disposal step I need to follow? Something else? Your help is much appreciated :)

  • Marshall a list of objects from VB6 to C#

    - by Andrew
    I have a development which requires the passing of objects between a VB6 application and a C# class library. The objects are defined in the C# class library and are used as parameters for methods exposed by other classes in the same library. The objects all contain simple string/numeric properties and so marshaling has been relatively painless. We now have a requirement to pass an object which contains a list of other objects. If I was coding this in VB6 I might have a class containing a collection as a member variable. In C# I might have a class with a List member variable. Is it possible to construct a C# class in such a way that the VB6 application could populate this inner list and marshal it successfully? I don't have a lot of experience here but I would guess Id have to use an array of Object types.

  • nmake makefile, linking objects files in a subfolder

    - by Gauthier
    My makefile defines a link command: prod_link = $(LINK) $(LINK_FLAGS) -o$(PROD_OUT) $(PROD_OBJS) where $(PROD_OBJS) is a list of object files of the form: PROD_OBJS = objfile1.obj objfile2.obj objfile3.obj ... objfileN.obj Now the makefile itself is at the root of my project directory. It gets messy to have object and listing files at the root, I'd like to put them in a subfolder. Building and outputing the obj files to a subfolder works, I'm doing it with suffixes and inference: .s.obj: $(ASSEMBLY) $(FLAGS) $*.s -o Objects\$*.obj The problem is to pass the Objects folder to the link command. I tried: prod_link = $(LINK) $(LINK_FLAGS) -o$(PROD_OUT) Objects\$(PROD_OBJS) but only the first file in the list of object files gets the folder's name. How can I pass the Objects subfolder to all files of my list $(PROD_OBJS)? EDIT I tried also PROD_OBJS = $(patsubst %.ss,Object\%.obj, $(PROD_SRC)) but got: makefile(51) : fatal error U1000: syntax error : ')' missing in macro invocation Stop. This is quite strange...

  • Qt, unit testing and mock objects.

    - by Eye of Hell
    Hello. Qt framework has internal support for testing via QtTest package. Unfortunately, i didn't find any facilities in it that can assist in creating mock objects. Qt signals and slots offers a natural way to create a unit-testing friendly units with input (slots) and output (signals). But is it any easy way to test that calling specified slot in object will result in emitting correct signals with correct arguments? Of course i can manually create a mock objects and connect them to objects being tested, but it's a lot of code. Maybe it's some techniques exists that allows to somehow automate mock objects creation while unit-testing Qt-based applications?

  • SSIS- Sharepoint list data transfer issue

    - by Vicky
    Hi , We are trying to transfer data from oracle database (about 60,0000) records only to a sharepoint list using SSIS. But we are getting following error when records reaches around 19000 . The attempt to add a row to the Data Flow task buffer failed with error code 0xC0047020 and System.ServiceModel.ProtocolException: The remote server returned an unexpected response: (400) Bad Request. Earlier we thought if could because of Sharepoint list limit so we tried by reducing two of the columns and then it has went fine. So we left with one of the column of Datatype DT_STR and length 400 in oracle beacuse of which issue might be happening, It is mapped to sharepoint custom list field of multiline type. We also verified if length of field is issue but in oracle DB for all records max length for this column is only 239 so length issue is also ruled out. Any one who has faced this kind of issue or knows cause of this issue.Kindly let us know.. Thanks and regards, Vicky

  • Alternatives to GameKIt for iPhone to iPhone transfer

    - by Mike
    I am needing to transfer information as an NSData object from one iPhone to another inside an application and was originally planning on using Bluetooth/GameKit, but the data looks like it will be in the neighborhood of 500KB - 1MB in size. I don't think this is going to fly with GameKit (Bluetooth) as it will take forever and it seems like people are having all kinds of issues with GK anyway. I'd prefer the users to not have to be on the same WiFi network to make it work but am running out of options and time so I'd probably be happy with whatever works. What is a reasonable alternative? The simpler the setup the better or something with sample code would be greatly appreciated and preferred. Thanks.

  • Can dummy objects be simulated on iphone?

    - by Mike
    I come from 3D animation and one of the basic things all 3D software have is the ability to create dummy objects. Dummy objects can be used to groups objects that can be rotated, moved or scaled together around a specific anchor point. This is the idea of what I am asking. Obviously we can have fake dummies by using a view and put other views as subviews, but this has problems as the view receives clicks and sometimes you don't want it to do so. You cannot change the anchorpoint of a view too. So, the dummies as I ask have, at least, these properties: adjustable anchor point it is not clickable it is totally invisible (cannot be rendered). any scale, rotation and translation of a dummy are propagated to the grouped objects considering the dummy's anchor point. it is totally animatable. Can this be simulated on iPhone? Is there any object that can be created to simulate this? thanks.

  • Silverlight 3 - Creating Custom Objects inside a Merged ResourceDictionary

    - by Tony Heupel
    I have custom classes that I currently instantiate within App.xaml as resources. I want to move these custom objects into a Merged ResourceDictionary, where they are used within styles, and keep them close to where they are used. Here's an example of what I want, arbitrarily using fake converter objects, but they could be any custom object... App.xaml (namespace declarations ommitted): <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Merged.xaml" /> </ResourceDictionary.MergedDictionaries> <Style x:Key="SomeStyle" TargetType="SomeControl"> ... </Style> ... </ResourceDictionary> And then in Merged.xaml (namespace declarations omitted): <ResourceDictionary> <cvt:VisibilityToBoolConverter x:Key="BoolToVisibility" Inverted="True"/> <cvt:VisibilityToBoolConverter x:Key="NotBoolToVisibility" Inverted="True" Not="True"/> <Style x:Key="SomethingThatUsesVisibilityToBoolConvertersStyle" TargetType="SomeOtherControl"> .... </Style> </ResourceDictionary> The issue I'm seeing is this: when I create the BoolToVisibility and NotBoolToVisibility objects (as well instantiating other objects that are instances of custom classes I have created) just as part Application.Resources, they are created and all the references work as expected; however, when I move these into a Merged Resource Dictionary (as I have in the sample above), I get a malformed Application exception when the Silverlight application loads. I belive this to be an issue with how objects are instantiated differently in Merged Resource Dictionaries (I belive it is more of a lazy-load approach), but I would expect it to work nonetheless. I am very much able to add Style objects, DataTemplates, ControlTemplates, and the like. But when I want to create instances of custom classes that are named or keyed using Xaml, it works great inside of App.xaml's Application.Resources directly and Application.Resources/ResourceDictionary as well. As soon as they are moved into a merged dictionary, it throws the exception. Is this by design? Any other ideas that work? Thanks in advance...

    - by iTayb
    I have the same classes on my server and on my web service. I have the following WebMethod: [WebMethod] public int CreateOrder(List<Purchase> p, string username) { o.Add(new Order(p,username)); return o.Count; } However the following code, run at server: protected void CartRepeater_ItemCommand(object source, RepeaterCommandEventArgs e) { List<Purchase> l = ((List<Purchase>)Session["Cart"]); if (e.CommandName == "Order") { localhost.ValidateService WS = new localhost.ValidateService(); WS.CreateOrder(l, Session["username"].ToString()); } } gives the following error: Argument '1': cannot convert from 'System.Collections.Generic.List<Purchase>' to 'localhost.Purchase[]'. How can I transfer the list<Purchase> object to the web service? Thank you very much.

  • Tomcat gzip while chunked issue

    - by hoodoos
    I'm expiriencing some problem with one of my data source services. As it says in HTTP response headers it's running on Apache-Coyote/1.1. Server gives responses with Transfer-Encoding: chunked, here sample response: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Content-Encoding: gzip Date: Tue, 30 Mar 2010 06:13:52 GMT And problem is when I'm requesting server to send gzipped request it often sends not full response. I recieve response, see that last chunk recieved, but then after ungzipping I see that response is partial. I never seen such behavior with gzip turned off in request headers. So my question is: is it common tomcat issue? maybe one of it's mod which is doing compression? Or maybe it maybe some kind of proxy issue? I can't tell about versions of tomcat or what gzip mod they use, but feel free to ask, i'll try ask my service provider. Thanks.

  • How can I transfer an NHibernate PersistentGenericSet over WCF

    - by Ian Oakes
    I'm trying to send objects retrieved by NHibernate over WCF, but whenever a have a property of ICollection I get an exception. When NHibernate gets the data from the database this property is intitialized with an instance of PersistentGenericSet. Is there a way I can send a PersistentGenericSet over WCF? -or- Is there some way making NHibernate initialize these properties with another type?

  • Having trouble animating Line in D3.js using and array of objects as data

    - by user1731245
    I can't seem to get an animated transition between line graphs when I pass in a new set of data. I am using an array of objects as data like this: [{ clicks: 40 installs: 10 time: "1349474400000" },{ clicks: 61 installs: 3 time: "1349478000000" }]; I am using this code to setup my ranges / axis's var xRange = d3.time.scale().range([0, w]), yRange = d3.scale.linear().range([h , 0]), xAxis = d3.svg.axis().scale(xRange).tickSize(-h).ticks(6).tickSubdivide(false), yAxis = d3.svg.axis().scale(yRange).ticks(5).tickSize(-w).orient("left"); var clicksLine = d3.svg.line() .interpolate("cardinal") .x(function(d){return xRange(d.time)}) .y(function(d){return yRange(d.clicks)}); var clickPath; function drawGraphs(data) { clickPath = svg.append("g") .append("path") .data([data]) .attr("class", "clicks") .attr("d", clicksLine); } function updateGraphs(data) { svg.select('path.clicks') .data([data]) .attr("d", clicksLine) .transition() .duration(500) .ease("linear") } I have tried just about everything to be able to pass in new data and see an animation between graph's. Not sure what I am missing? does it have something to do with using an array of objects instead of just a flat array of numbers as data?

  • Binding list of objects to WPF ListView

    - by Dave Colwell
    Hi all, I have a list of objects which i want to bind to a ListView control in my WPF application. The Objects have a DataTemplate already, so no need to define that. The list of objects is a property in the codebehind file in the format list<object> When i add one object programatically, it appears fine. But when i try to bind the ItemSource of the ListBox to the list of objects, nothing shows up. I am using the following binding: ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=Portfolios}" where the name of the property i am trying to bind to is Portfolios and exists on the parent window

  • Fastest way to iterate through an NSArray with objects and keys

    - by AppGolfer
    Hello, I have an NSArray called 'objects' below with arrayCount = 1000. It takes about 10 secs to iterate through this array. Does anyone have a faster method of iterating through this array? Thanks! for (int i = 0; i <= arrayCount; i++) { event.latitude = [[[objects valueForKey:@"CLatitude"] objectAtIndex:i] floatValue]; event.longitude = [[[objects valueForKey:@"CLongitude"] objectAtIndex:i] floatValue]; }

  • Marshal a list of objects from VB6 to C#

    - by Andrew
    I have a development which requires the passing of objects between a VB6 application and a C# class library. The objects are defined in the C# class library and are used as parameters for methods exposed by other classes in the same library. The objects all contain simple string/numeric properties and so marshaling has been relatively painless. We now have a requirement to pass an object which contains a list of other objects. If I was coding this in VB6 I might have a class containing a collection as a member variable. In C# I might have a class with a List member variable. Is it possible to construct a C# class in such a way that the VB6 application could populate this inner list and marshal it successfully? I don't have a lot of experience here but I would guess Id have to use an array of Object types.
