Body
You can overwrite Object in Chrome/V8 and bad things happen if you do. Typing the following gets these responses. <pre><code>> Object function Object() { [native code] } > Number function Number() { [native code] } </code></pre> Looking at Number.prototype we can see a full set of methods and Object as Number's prototype: <pre><code>Number constructor: function Number() { [native code] } toExponential: function toExponential() { [native code] } toFixed: function toFixed() { [native code] } toLocaleString: function toLocaleString() { [native code] } toPrecision: function toPrecision() { [native code] } toString: function toString() { [native code] } valueOf: function valueOf() { [native code] } __proto__: Object __defineGetter__: function __defineGetter__() { [native code] } __defineSetter__: function __defineSetter__() { [native code] } __lookupGetter__: function __lookupGetter__() { [native code] } __lookupSetter__: function __lookupSetter__() { [native code] } constructor: function Object() { [native code] } hasOwnProperty: function hasOwnProperty() { [native code] } isPrototypeOf: function isPrototypeOf() { [native code] } propertyIsEnumerable: function propertyIsEnumerable() { [native code] } toLocaleString: function toLocaleString() { [native code] } toString: function toString() { [native code] } valueOf: function valueOf() { [native code] } </code></pre> But if we overwrite Object <pre><code>Object = {} </code></pre> Number's prototype goes a bit wonky: <pre><code>Number.prototype > Number ...empty... </code></pre> As Object is the root of the hierarchy there's a bit of a paradox if you reassign it to another object.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
