Book Description

This creative guidebook teaches librarians in diverse communities how to develop and implement early learning programming beyond traditional storytimes. While traditional library storytimes are excellent tools for families, equally important is play. Children learn through play in many ways; it stimulates exploration and curiosity and builds gross and fine motor skills that are critical to reading and writing success. Perhaps most importantly, play has the power to cross barriers of culture and language, allowing families from differing backgrounds to learn together. In this book, Kristin Grabarek and Mary R. Lanni—the pioneers of Little University, an early learning program that focuses on play-based learning—share their experiences and provide guidance for implementing similar programs at libraries of various sizes and budgets. They teach readers how to create programs for a diverse group of families, work with outside providers, choose supplies, estimate costs, market your programming, and overcome the challenges of both big and small budgets and many or few patrons. These practical plans will enhance storytimes and even help build a brand-new early learning program.

As an Enterprise Service Bus (ESB), WSO2 Enterprise Integrator provides greater flexibility and agility to meet growing enterprise demands, whereas, as a Data Services Server (DSS), it provides an easy-to-use platform for integrating data stores, creating composite views across different data sources, and hosting data services. Using real-world scenarios, this book helps you build a solid foundation in developing enterprise applications with powerful data integration capabilities using the WSO2 servers. The book gets you started by brushing up your knowledge about SOA architecture and how it can be implemented through WSO2. It will help build your expertise with the core concepts of ESB such as building proxies, sequences, endpoints, and how to work with these in WSO2. Going further, you will also get well-acquainted with DSS data service concepts such as configuring data services, tasks, events, testing, and much more. The book will also cover API management techniques. Along with ESB and DSS, you will also learn about business process servers, the rules server and other components that together provide the control and robustness your enterprise applications will need. With practical use cases, the book covers typical daily scenarios you will come across while using these servers to give you hands-on experience.
