### Data from Companies  
Government databases that maintain data about local companies are relevant in supporting economic development, regulatory compliance, and public transparency. These databases collect and store extensive information about businesses operating within a jurisdiction, providing valuable resources for government agencies, businesses, and the public. In Brazil, companies' data are maintained by several institutions, with the primary source being the National Register of Companies (CNPJ), which Brazilian Customs manage. This database contains information about all registered companies in the country, including financial data, tax obligations, and legal status.  
Federal and provincial agencies manage Canada's company databases. The most important is Corporations Canada, which administers the federal incorporation process and maintains a database of federally incorporated businesses [107]. Additionally, each province, such as Ontario and British Columbia, maintains its own registry of provincially incorporated companies. The databases include information on company status, directors, and financial filings, providing a robust framework for understanding the corporate landscape in Canada. In the United States, corporate databases are decentralized, with each state maintaining its own registry. The Securities and Exchange Commission oversees publicly traded companies through its EDGAR database, which contains detailed financial statements and disclosures [108].  
China's corporate databases are managed by the State Administration for Market Regulation, which oversees company registration and regulation [109]. The Ministry of Corporate Affairs manages the primary corporate database in India [110]. This database includes information on company incorporation, directors, financial statements, and annual returns.  
France companies' databases are primarily managed by the National Institute of Industrial Property, which includes information on company registration, financial statements, and legal filings [111]. In the United Kingdom, Companies House is the primary repository for corporate data, maintaining a database of all registered companies [112]. This includes information on incorporation, directors, annual returns, and financial statements. Germany's corporate databases are managed by local courts' commercial registers (Han

Among the data commonly found in this type of database, it is important to highlight information on a company's partners and the company's monetary value. This information is crucial, as establishing a company is one of the primary methods used to conceal assets. The entities and relationships presented in Table 10 were mapped using the attributes found in these databases.
