graph engine

有個僥倖的機會，參與了微軟的項目，僥倖的接觸了，graph engine圖形數據庫，感受非常新穎，作點記錄，和你們分享，理解有限，發現不足之處，還請指點。

微軟發分佈式圖處理引擎GraphEngine1.0

歸納介紹：

http://tech.it168.com/a2015/0521/1730/000001730780.shtml

下面介紹一個官網的demo：

 

 

首先建立一個Data Modeling Projiect.建立數據模型以下：

//角色
cell struct Character
{
String Name;
byte Gender;
bool Married;
long Spouse;
long Performer;
}
//演員
cell struct Performer
{
String Name;
int Age;
List<long> Characters;
}
cell struct Friendship
{
List<long> friends;
}

建立GE application project：

直接調用上面數據模型便可。

//using Trinity.Extension;官網上要引用這個明明空間，咱們有引用，程序也完成了。不知道爲何啊？

//採用嵌入式的方式，相對而言，這種方式比客戶端的方式簡單一些。

TrinityConfig.CurrentRunningMode = RunningMode.Embedded;

//如下是根據數據模型創建的關係鏈接。

咱們首先建立12個實體單元

// Characters
Character Rachel = new Character(Name: "Rachel Green", Gender: 0,
Married: true);
Character Monica = new Character(Name: "Monica Geller", Gender: 0,
Married: true);
Character Phoebe = new Character(Name: "Phoebe Buffay", Gender: 0,
Married: true);
Character Joey = new Character(Name: "Joey Tribbiani", Gender: 1,
Married: false);
Character Chandler = new Character(Name: "Chandler Bing", Gender: 1,
Married: true);
Character Ross = new Character(Name: "Ross Geller", Gender: 1,
Married: true);

// Performers
Performer Jennifer = new Performer(Name: "Jennifer Aniston", Age: 43,
Characters: new List<long>());
Performer Courteney = new Performer(Name: "Courteney Cox", Age: 48,
Characters: new List<long>());
Performer Lisa = new Performer(Name: "Lisa Kudrow", Age: 49,
Characters: new List<long>());
Performer Matt = new Performer(Name: "Matt Le Blanc", Age: 45,
Characters: new List<long>());
Performer Matthew = new Performer(Name: "Matthew Perry", Age: 43,
Characters: new List<long>());
Performer David = new Performer(Name: "David Schwimmer", Age: 45,
Characters: new List<long>());

 

//定義一個描述關係，說明咱們是如何表示直接關係的。主要是演員和角色的關聯

// Portrayal Relationship
Rachel.Performer = Jennifer.CellID;
Jennifer.Characters.Add(Rachel.CellID);

Monica.Performer = Courteney.CellID;
Courteney.Characters.Add(Monica.CellID);

Phoebe.Performer = Lisa.CellID;
Lisa.Characters.Add(Phoebe.CellID);

Joey.Performer = Matt.CellID;
Matt.Characters.Add(Joey.CellID);

Chandler.Performer = Matthew.CellID;
Matthew.Characters.Add(Chandler.CellID);

Ross.Performer = David.CellID;
David.Characters.Add(Ross.CellID);

//表示一種配偶的關係

// Marriage relationship
Monica.Spouse = Chandler.CellID;
Chandler.Spouse = Monica.CellID;

Rachel.Spouse = Ross.CellID;
Ross.Spouse = Rachel.CellID;

// Friendship
Friendship friend_ship = new Friendship(new List<long>());
friend_ship.friends.Add(Rachel.CellID);
friend_ship.friends.Add(Monica.CellID);
friend_ship.friends.Add(Phoebe.CellID);
friend_ship.friends.Add(Joey.CellID);
friend_ship.friends.Add(Chandler.CellID);
friend_ship.friends.Add(Ross.CellID);

//運行時對象能夠很容易的轉換爲內存存儲單元，下面是保存的代碼

// Save Runtime cells to Trinity memory storage
Global.LocalStorage.SavePerformer(Jennifer);
Global.LocalStorage.SavePerformer(Courteney);
Global.LocalStorage.SavePerformer(Lisa);
Global.LocalStorage.SavePerformer(Matt);
Global.LocalStorage.SavePerformer(Matthew);
Global.LocalStorage.SavePerformer(David);

Global.LocalStorage.SaveCharacter(Rachel);
Global.LocalStorage.SaveCharacter(Monica);
Global.LocalStorage.SaveCharacter(Phoebe);
Global.LocalStorage.SaveCharacter(Joey);
Global.LocalStorage.SaveCharacter(Chandler);
Global.LocalStorage.SaveCharacter(Ross);

// Dump memory storage to disk for persistence
Global.LocalStorage.SaveStorage();

long spouse_id = -1;

using (var cm = Global.LocalStorage.UseCharacter(Monica.CellID))
{
if (cm.Married)
spouse_id = cm.Spouse;
}

using (var cm = Global.LocalStorage.UseCharacter(spouse_id))
{
Console.WriteLine(cm.Name);
}

Console.Read();
