Company and Summary of Significant Accounting Policies and Estimates (Textual) [Abstract]      
Revenue, performance obligations, timing   Subscriptions are typically sold with a three to five year initial term with a customer option to renew on an annual basis after the initial term. Term licenses generally have a two-year initial term with a customer option to renew on an annual basis after the initial term. In certain circumstances, the Company will enter into term licenses with an initial term of more than two years or a renewal period longer than one year. Support for term licenses follows the same contract periods. Professional services typically are time and materials contracts that last for an average period of approximately one year.
