 * TODO: Very early on let's add some form of BSON / binary data so they can upload images and docs.
 *       The SQL Parser allows for a type called BINARY. In that we would store the hash of the entity containing the data.
 * Here are the types the parser recognizes for CREATE TABLE:
 *
 * Expected "#", "--", ".", "/*", "BIGINT", "BINARY", "BIT", "CHAR", "COLLATE", "DATE", "DATETIME", "DECIMAL", "DOUBLE",
 * "ENUM", "FLOAT", "GEOMETRY", "GEOMETRYCOLLECTION", "INT", "INTEGER", "JSON", "LINESTRING", "LONGTEXT", "MEDIUMINT",
 * "MEDIUMTEXT", "MULTILINESTRING", "MULTIPOINT", "MULTIPOLYGON", "NUMERIC", "POINT", "POLYGON", "SET", "SMALLINT",
 * "TIME", "TIMESTAMP", "TINYINT", "TINYTEXT", "VARBINARY", "VARCHAR", "YEAR", "blob", "boolean", "longblob",
 * "mediumblob", "tinyblob", or [ \t\n\r] but "T" found.
