Design consideration and goals Few aspects need to be considered in order to achieve the goals of designing the Mobile Database System or MDS. Performance need to be stabilized due to the mobility usage. The design of the MDS should be unobtrusive interface. The MDS is reliable to fulfill the high expectation of mobile users. Lastly the scalability of the MDS, these includes, everyone will synchronize at the same time. Merge replication, let database engines synchronize the local database that resides on the mobile device with a central database running on a server. Determine how the data will be imported or exported to the driving database on the server as part of the database strategy. Plan the synchronization strategy as part of the database design phase Mobile Database Design Mobile database design is base on eight steps. The particular steps will help the design goal of MDS will succeed. The Figure 1 below will show the flow of the eight mobile database design steps. 1. Mobile Pla...

Basically SAP, an enterprise application is made up of programs together with the data used and formed by programs. The data are organized in a meaningful way within the database, making it easy for the programs to access and find the data necessary to do something useful like run a financial report or create a sales order. Both the programs as well as data exist in the same database in the case of an SAP component or products such as ECC. Normally each and every component has its own database a production system landscape composed of SAP ECC, SAP Business Warehouse (BW), and SAP Customer Relationship Management (CRM) consists of three production databases. Database Structure: Essentially database is an electronic filing system that houses a collection of information organized in such a way that allows a computer program to find preferred pieces of data in a rapid way. A database is composed of tables, columns (called fields), and rows (called records or data). The fundamental structur...

Transaction processing within the parlance of data base management systems is when SQL statements that are required to be executed on the database are grouped into units of transactions. This ensures that a single transaction executes a whole unit or does not execute at all. Let us for example take a banking transaction during which X transfers some money to Y. There should be a debit of X’s account and a corresponding credit into Y’s account. Imagine if there is a fatality during the transaction where the transaction which increases the bank balance of Y cannot be completed due to a disk crash or due to a power failure etc., in such a case the system will cease to be consistent as it has completed a transaction namely a debit, but did not complete the corresponding credit transaction due to a power failure or a hard disk crash. Let us also consider the alternative where both these database operations are bundled into a transaction, so either both execute together or both do...

Microsoft Access is showing its age. Most of the techniques (File Server, VBA, DAO, Jet Database Engine, etc) hark back 20 or more years. Microsoft will continue supporting VBA for many years to come, but the programming emphasis is rapidly changing in favour of Visual Basic.Net and SQL Server. For company administration systems, the combination of a VB.Net FrontEnd with an SQL Server BackEnd database is the ideal. Visual Basic is business rules oriented and SQL Server is efficient and easy to maintain. VB.Net Upgrade Conversion Reasons The reasons for an upgrade from Microsoft Access to Visual Basic.Net and an SQL Server database are: A strategic corporate decision A worry about the future of Visual Basic for Applications (VBA) The difficulty and cost in supporting obsolete and error ridden code The difficulty and cost in supporting code written by amateurs without regard to standards The need to replace an inefficient administration system that just “grew like Topsy” The n...

PHP and MySQL are two components that are almost always present in every web-based program. Data-driven Web applications can use the MySQL which has the main advantages of open source applications. In each database in MySQL there are a few tables. To learn how to access the data contained in the MySQL database, create a database instance with the name “online-store” . Databases can be created using the SQL command “create database online-store” or using PHPMyadmin . Later in the database table named instance make an “employee” table with the columns in it is the “id”, “first-name”, “last-name”, “address” . You can create table “employee” using SQL command as follows: CREATE TABLE IF NOT EXISTS `employee` ( `id` int(11) NOT NULL AUTO_INCREMENT, `first-name` varchar(50) NOT NULL, `last-name` varchar(50) NOT NULL, `address` varchar(200) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHAR...

Working with Microsoft Access designing a new database, the question here is what is the core process of the database that you are trying to define? Access Database design is more of an art than a science and common sense will prevail. By taking the time to identify the core process correctly, you will find that additional processes will plug in easily keeping the structure of the system stable and solid enough as time goes by and data volume increases. If you apply some of Microsoft Access techniques including ‘Database Normalisation’ rules (up to the third norm) and deal with relationships (tables joins) and setting their keys & indexes, this too will determine the solid foundation to build on. Scenario: Let’s take an example process like a ‘Sales Order Processing’ database system which has a list of international customers based in the UK, USA and/or Canada who place orders (eventually invoiced) for one or more food products (items) periodically (fo...

Your client database can generate money in the bank over and over and over again. Many small business owners do not take the time to build a client email list. This is one of the biggest marketing mistakes a small owner can make. Why? An existing customer is your best customer and being able to communicate with him at a moment’s notice is crucial. Example of How to Trip Your Monthly Income: You own a dress store. You are at a fashion convention to purchase new clothing for the fall. You run across a beautiful unique coat, but you are not sure if your customers will like the coat. The coat is fairly expensive, even at the wholesale price and you would hate to purchase 3 or 4 and they just sit on the rack. Solution: Send your client database an e-mail with an image and your price for the item. Tell them that you are in New York City at the Annual Fashion Convention and want to know if any one would be interested in the coat? You explain that there is a limited number of the coats av...

Any serious business endeavor should have come up with a good database management system. This is a very crucial element that ensures you have everything under control.

The software is also a good tool to maintain your contacts with the members of your web site. Aside from storing the information entered by members, you can also use the software to send messages and do tasks as ...

The Field Design & Validations This is the last step which completes the ‘back-end’ database design process and steps 6 and 7 (later articles to follow) focuses on the ‘front-end’ database design process and is deemed optional to this final step of the ‘back-end’ database design process. In this section, I’m going to discuss the process which talks about the field’s properties and the business rules of how fields control data input. If you are not designing input screens (Access Forms), then the process could effectively stop here. If however, you intend to handle ‘front-end’ processes for your database, this is the preliminary step of setting the best fit attributes (ideally in table design view mode). You will therefore need to know about what properties are and how and where you apply them. Properties is a general term to describe an attribute of an object. For an example, a field (the object) has many attributes to it ...

I’m often hired to carry out and audit an Access database application that has been built and re-developed over the years due to: The developer (perhaps a former employee) has since left the organisation and left no documentation. An individual has accidentally locked a database and can not gain access which requires an official ‘hack’. Some of the components to the Access database has been lost and users need some new functions added. New administrators have been given a database and do not have enough knowledge to extend the system reports. The client wants an honest opinion on how well (or poorly) designed an Access database has been built and implemented. But with a little bit of training and know how, there are some basic but simple tasks that users can carry out for themselves to breakdown and understand an Access database before calling in the repairman/woman. I have 5 common tips to help you on your way: With most well designed Access database systems, you norm...

PHP is one of the “scripting languages” of the Web. It is an interpreted language, interpreted by the official PHP interpreter, developed specifically for web programming. Being quite similar to ASP in many ways, chances are a change from ASP to PHP would not be all that difficult for a seasoned developer who was experienced in a C-style language. PHP, combined with Apache, or another web server handles all the “standard” web serving side of development; it watches for requests, it hands them off to the appropriate handlers, it sends the required headers, and it finalizes the job. On it’s own, PHP is a language capable of many simple things: date functions, file manipulation, mathematics, logic, all the traditional programming language stuff (including some very feature-filled mechanics for topics such as string manipulation and date manipulation) – but it doesn’t expand in to the power given by database driven web applications. Luckily, there a...

Passing the Oracle Database 12c: Essentials exam (1Z0-497) will earn exam candidates the Oracle Database 12c Certified Implementation Specialist certification. It will also make them an OPN Certified Specialist in Oracle 12c if they are employed by a company that is part of the Oracle Partner Network (OPN). Partner companies with employees who are certified as OPN specialists gain a higher level of specialization in the OPN program. As such, this credential makes you a more attractive employee to companies that are part of the Oracle Partner Network. The 1Z0-497 exam is a standalone test and is not part of any track. To earn the related certification requires only passing the exam. There is no required training or other pre-requisites. The 12c database will be Oracle’s flagship product for several years to come and this exam will be a popular one for some time. This exam covers many of the same topics as the 12c database administrator track but does not require the same depth of...
