  • Estimating the Complexity of Your Microsoft® Access® Project an Opengate White Paper
    Estimating the Complexity of Your Microsoft® Access® Project An OpenGate White Paper Traditional Access UI Design Microsoft Access is the world's leading desktop database application, with approximately 12 million licensed copies worldwide (according to Microsoft sources). With MS Access readily available on many PCs at work, a large number of prospective users try their hand at creating an Access database appliction to improve their group's productivity and minimize information errors often caused by maintaining data in spreadsheets. While Microsoft made many improvements in Access 2007 to simplify database creation, there is still much to learn when developing an Access database project. This brief paper is intended to help you better gauge how complex your project may be in order to evaluate the trade-offs between using a spreadsheet-based method versus Microsoft Access. Step 1: Determine Your Database's Purpose The first thing to identify is the purpose of your database. There are two fairly buckets you can place a database project into: A) A database that can be used to organize and track information. The simplest type of database, these sorts of projects are primarily to make sure you are efficiently storing information you need. Unlike spreadsheets, a simple database can help you avoid entering the same information multiple times, as well as help avoid errors like duplication of a customer name, or a misspelled product name that causes your reports and charts to show inaccurate data. If this is the type of database you will be creating, give this step a score of 1 B) A database that can be used to organize and track information and automate one or more processes.

  • Introduction to Microsoft Access 2010
    Introduction to Microsoft Access 2010 A database is a collection of information that is related. Access allows you to manage your information in one database file. Within Access there are four major objects: Tables, Queries, Forms and Reports. Tables store your data in your database Queries ask questions about information stored in your tables Forms allow you to view data stored in your tables Reports allow you to print data based on queries/tables that you have created The Navigation Pane The Navigation Pane is a list containing every object in your database. For easier viewing, the objects are organized into groups by type. You can open, rename, and delete objects using the Navigation Pane. To Minimize and Maximize the Navigation Pane: Click the double arrow in the upper-right corner of the Navigation Pane to minimize and maximize. 5-13 1 Sorting the Objects in the Navigation Pane: By default, objects are sorted by type, with the tables in one group, the forms in another, etc. However, you can change how the objects are sorted. Click the drop-down arrow to the right of the All Access Objects and click on a sort option from the list. Creating a Database 1) Start Access 2) Select Blank Database 3) Under File Name type a name for the database 4) To change the location of where to store the database, click the folder icon and select a location 5) Click Create Access opens in a new table in Datasheet View. 2 Understanding Views There are multiple ways to view a database object.

  • Exploring the Visualization of Schemas for Aggregate-Oriented Nosql Databases?
    Exploring the Visualization of Schemas for Aggregate-Oriented NoSQL Databases? Alberto Hernández Chillón, Severino Feliciano Morales, Diego Sevilla Ruiz, and Jesús García Molina Faculty of Computer Science, University of Murcia Campus Espinardo, Murcia, Spain {alberto.hernandez1,severino.feliciano,dsevilla,jmolina}@um.es Abstract. The lack of an explicit data schema (schemaless) is one of the most attractive NoSQL database features for developers. Being schema- less, these databases provide a greater flexibility, as data with different structure can be stored for the same entity type, which in turn eases data evolution. This flexibility, however, should not be obtained at the expense of losing the benefits provided by having schemas: When writ- ing code that deals with NoSQL databases, developers need to keep in mind at any moment some kind of schema. Also, database tools usu- ally require the knowledge of a schema to implement their functionality. Several approaches to infer an implicit schema from NoSQL data have been proposed recently, and some utilities that take advantage of inferred schemas are emerging. In this article we focus on the requisites for the vi- sualization of schemas for aggregate-oriented NoSQL Databases. Schema diagrams have proven useful in designing and understanding databases. Plenty of tools are available to visualize relational schemas, but the vi- sualization of NoSQL schemas (and the variation that they allow) is still in an immature state, and a great R&D effort is required to achieve tools with the desired capabilities. Here, we study the main challenges to be addressed, and propose some visual representations. Moreover, we outline the desired features to be supported by visualization tools.

It can be deployed in on-premise data centers and cloud. It is well- Linear scalability suited for high volume and velocity workloads, like Internet of Things, 360- High availability degree customer view, online contextual advertising, fraud detection, mobile Fast and easy deployment application, user personalization, and online gaming. Developers can use a single Smart topology management application interface to quickly build applications that run in on-premise and Online elastic configuration cloud environments. Multi-region data replication Enterprise grade software Applications send network requests against an Oracle NoSQL data store to and support perform database operations. With multi-region tables, data can be globally distributed and automatically replicated in real-time across different regions. Data can be modeled as fixed-schema tables, documents, key-value pairs, and large objects. Different data models interoperate with each other through a single programming interface. Oracle NoSQL Database is a sharded, shared-nothing system which distributes data uniformly across multiple shards in a NoSQL database cluster, based on the hashed value of the primary keys. An Oracle NoSQL Database data store is a collection of storage nodes, each of which hosts one or more replication nodes. Data is automatically populated across these replication nodes by internal replication mechanisms to ensure high availability and rapid failover in the event of a storage node failure.

  • Introduction to Microsoft Powerapps for Access Web Apps Developers
    ABSTRACT The one constant in software technology is that it’s constantly changing. You might ask: “What alternative is there to create a mobile or online solution for Microsoft Access?” Microsoft believes that Microsoft PowerApps is the answer. Although PowerApps is a relatively new product, Microsoft is making a significant investment in PowerApps to make it a premiere tool for business solutions and is adding new features on a regular basis. The purpose of this white paper is to demonstrate that PowerApps is a successor tool worthy of consideration for an Access web apps power user and developer. What follows is an in-depth comparison of INTRODUCTION TO PowerApps and Access Web apps that examines the pros, cons, and similarities of each tool, their key features, and the way data is managed. Hopefully, MICROSOFT you’ll take the time to try out PowerApps and add it to your business solutions toolkit.
