I FINALLY RECOVERED ALL MY LOST BITCOIN SUCCESSFULLY THROUGH META TECH RECOVERY PRO

It all started with a simple error; I mistakenly made some settings on my phone, which affected my phone's operational settings. No big deal, I thought. I’ve done this before. But this time was different. I noticed a change on my device; many apps weren't working, mainly my crypto wallet—it held my crypto wallet, which contained $512,000 worth of Bitcoin. When I realized what I’d done, I froze, then panicked. No backups. No seed phrase written down. Nothing. I tried to stay calm, but every second that passed felt like a countdown to permanent loss. I spent hours online, reading recovery guides, downloading data recovery tools, and more. While scrolling through a late-night tech forum, I saw a thread about crypto investment and forex trading scam victims and how they managed to get restitution. Someone mentioned a crypto recovery specialist called META TECH RECOVERY PRO, known for handling complex wallet recoveries and also recovering funds lost to scams. I was skeptical, the internet is wide and wild, you never know who is on the other side of the screen, for me to just easily release my wallet information to. 

I reached out to META TECH RECOVERY PRO out of desperation because what do I have else to lose? I was never expecting a swift engagement; their response was quick and professional. Their confidence, reviews, and composure made me believe they are worthy of handling my task. They were transparent, knowledgeable, and honest. That was more than I’d gotten from any recovery software I have been downloading for weeks, and paying for passkeys. They laid out their working terms, which were straightforward, and their price was fair. It was a back-and-forth phase with META TECH RECOVERY PRO during the recovery of my lost Bitcoin Wallet. META TECH RECOVERY PRO was able to recover my Bitcoin wallet seed phrase. My wallet was safe. The funds were untouched, and that's when I concluded that you can never find any reliable recovery professional on Google besides META TECH RECOVERY PRO. That experience taught me more than I ever wanted to know about digital security and about how fragile digital assets can be without proper backup. But it also reminded me that even in the worst situations, there’s still hope if you know where to look, and as for me, META TECH RECOVERY PRO was my ray of light. 

If you ever find yourself in that kind of nightmare, don't forget to contact,

Definições e Referências de Cubos de Analytics

Talvez isso já seja bem conhecido, mas quis compartilhar para ajudar.

 

Considere que você tem as seguintes definições de classes persistentes:

Uma classe Invoice (Fatura) com uma propriedade de referência para Provider (Prestador de serviço):

Class Sample.Invoice Extends (%Persistent, %Populate)
{
Parameter DSTIME = "AUTO";
Property InvoiceNumber As %Integer(MINVAL = 100000) [ Required ];
Property ServiceDate As %Date(MINVAL = "+$h-730") [ Required ];
Index InvoiceNumber On InvoiceNumber;
Property Provider As Sample.Provider [ Required ];
Index Provider On Provider [ Type = bitmap ];
/// Build some invoices, this will firstly create 100 Providers
/// <Example>
/// Set tSC=##class(Sample.Invoice).Build()
/// </example>
ClassMethod Build(pCount As %Integer = 100020, pInit As %Boolean = 0) As %Status
{
    #dim tSC 			As %Status=$$$OK
    #dim eException  	As %Exception.AbstractException
    try {
        If pInit {
            $$$THROWONERROR(tSC,##class(Sample.Provider).%KillExtent())
            $$$THROWONERROR(tSC,##class(Sample.Invoice).%KillExtent())
        }
        $$$THROWONERROR(tSC,##class(Sample.Provider).Populate(100))
        $$$THROWONERROR(tSC,##class(Sample.Invoice).Populate(pCount))
    }
    catch eException {
        Set tSC=eException.AsStatus()
    }
    Quit tSC
}
}

E a classe Provider

Class Sample.Provider Extends (%Persistent, %Populate)
{

Property Name As %String [ Required ];
Property NPI As %Integer(MAXVAL = 9000000000, MINVAL = 100000000) [ Required ];
}

Se você chamar o método Build da Sample.Invoice, poderá consultar isso via SQL:

SELECT
InvoiceNumber,Provider->Name, Provider As ProviderId,ServiceDate
FROM Sample.Invoice

E verá algo como:

O ponto que este artigo discute é: como criar uma dimensão no Provider.

O que eu descobri que funciona bem é seguir esse padrão:

O que isso faz:

  1. Define o identificador único da dimensão como o Id do Provider (que vem de Sample.Provider).
    Isso é importante porque é perfeitamente possível existir mais de um prestador com o nome SMITH, JOHN.
    Ao definir o nível da dimensão na propriedade Provider, estamos dizendo para construir a tabela de dimensão baseada em um Provider único.

Se olharmos na tabela de dimensão gerada, veremos:

  1. Define uma propriedade para o nível que:
    • Identifica a propriedade como Provider.Name
    • Define que o valor deve ser buscado em tempo de execução (Get value at runtime = Yes)
    • Usa esse valor como nome dos membros da dimensão (Use as member names = Yes)

Isso tem como efeito colateral gerar na tabela de dimensão a seguinte declaração de propriedade:

/// Dimension property: Name<br/>
/// Source: Provider.Name
Property Name As %String(COLLATION = "SQLUPPER(113)", MAXLEN = 2000) 
[ Calculated, 
SqlComputeCode = {Set {Name}=##class(Sample.BI.Cube.Invoice.Provider).%FetchName({Provider})}, SqlComputed ];

Com o método %FetchName assim:

/// Fetch the current value of %FetchName.<br/>
/// Generated by %DeepSee.Generator:%CreateStarTable.
ClassMethod %FetchName(pKey As %String) As %String
{
 // If we don't a value, show key as this is most likely the NULL substitute
 Set tValue=pKey
 &SQL(SELECT Name INTO :tValue FROM Sample.Provider WHERE %ID = :pKey)
 Quit tValue
}

 

O que isso significa?
Quando os membros da dimensão são recuperados, o que será exibido é o nome do Provider e não o seu Id.

No Analyzer, podemos ver:

Por que isso é importante?

  • Se o nome de um Provider for alterado na Sample.Provider, o cubo não precisa ser reconstruído ou sincronizado.
    Se tivermos centenas de milhões de faturas e o nome de um único Provider mudar, não queremos reconstruir ou sincronizar todo o cubo de Invoice só por isso.
  • A tabela de dimensão para Provider é baseada no Provider.Id, o que permite termos mais de um Provider com o mesmo nome na tabela de dimensões/cubo.
  • Se, em vez de definir a propriedade do nível da dimensão dessa forma, definirmos como Provider.Name, o identificador único da dimensão passa a ser o nome, o que faz com que todos os Providers com o mesmo nome sejam agrupados sob o mesmo nome.
  • E, se o nome de um Provider for alterado, somos obrigados a reconstruir o cubo.
