A start-up routine for a Switched-Mode Power Supply (SMPS) gradually increases the duty cycle while reducing an initial dead time to a final optimal dead time for normal operation. Reliability is improved by the larger initial dead time that reduces ringing in switching transistors during low-voltage conditions early in the start-up sequence. Efficiency is improved by reducing the optimal dead time as voltages approach operating levels. The initial dead time is pre-calculated as a function of the input voltage and initial duty cycle. Optimal dead times are pre-calculated as a function of output voltage and output current. The optimal dead time is adjusted for each iteration of a second loop that also increases duty cycle until the target operating output voltage is reached.

For which database a query that is received from the outside and described corresponding to the structure of the first database is a query is determined with reference to the conversion table. When the query is determined to be a query for the second database, the query is converted and is introduced into the second database, and a query result in response to the query is converted into a format corresponding to the structure of the first database and output.

Various methods, apparatuses/systems, and media for implementing a smart database driver are disclosed. A receiver receives a request for establishing a connection between an application and a target database. A processor, operatively coupled to the receiver via a communication network, authenticates the application by implementing a java authentication authorization service (jaas). Authentication of the application is performed at runtime with connection properties and configuration details provided via system properties or environment variables. The processor also generates a database connection uniform resource locator (URL), validates the URL; and establishes a connection between the application and the target database based on the validation of the URL and successful authentication of the application.

In example embodiments, techniques are provided for decoupling user access to infrastructure models from proprietary software that maintains and updates the infrastructure models. A backend application may include an infrastructure modeling backend module that, among other functions, handles communication with an infrastructure modeling frontend module of a frontend application that provides user access to the infrastructure model, infrastructure modeling hub services that maintain repositories for the infrastructure model, and an infrastructure modeling native module that creates, performs operations upon, and updates local instances of a database that stores the infrastructure model. While the infrastructure modeling backend module may pass information obtained from the infrastructure modeling frontend module and infrastructure modeling hub services to the infrastructure modeling native module, it may be functionally separated from the software of the infrastructure modeling native module that understands how to maintain and update infrastructure models, including interacting with local instances of the database.

Embodiments provide a computer-implemented method for automatic detection of an event from an enterprise application, comprising: initiating a CRUD action connector of an integration platform; providing a business object name to the action connector; randomly obtaining a sample record from the enterprise application; creating a dummy record in the enterprise application, wherein the dummy record has a dummy record ID and a first time range within which the dummy record is created; and searching for a first timestamp field in a business object schema to determine whether the first timestamp field is queryable, wherein the first timestamp field indicates when the dummy record is created. If the first timestamp field exists, and the first timestamp field is queryable, then a first event indicating creation of the dummy record is detectable; if the first timestamp field does not exist, then the first event is undetectable.

A database management engine provides a user interface that allows users to access and modify employee information in a database. The database includes entries for employees, and each database entry includes identifying information about the associated employee. A user can request to modify data within database entries, for instance in order to update information associated with an employee. Responsive to the request, the database management engine identifies liabilities associated with the database modification stemming from associated tax laws. Based on the identified tax liabilities, the engine computes the aggregate tax liability owed by the employer and/or employee. Before modifying a database entry, the engine modifies the user interface to include interface elements detailing the computed aggregate tax liability. The user explicitly can be required to confirm the database modification in view of the aggregate tax liability. Once a user gives explicit confirmation, the engine modifies the database entry.
